I am very disappointed with All-Battery’s customer service.  
To summarize the events:  
I ordered the R2U AA 2300mAh batteries on 11-29-2008 when the items were in stock. The packing slip that came with the order indicated the R2U batteries were sent with the order however 2600mAh batteries were placed in the package instead.  
I reported the error and was told that the R2U batteries are out of stock and to either keep the wrong batteries or wait until 01/31/2009 for an exchange. I responded by saying I did not want the wrong batteries/ to wait and requested instructions for return/refund. I am then told to return the wrong batteries at my cost and then a credit for shipping/items would be made.  
These are my complaints regarding the above statements:  
The purpose of a Packing Slip is to show what is placed in the package. Clearly this company lacks quality control because the packing slip shows the ordered batteries but wrong batteries were placed in the package. And now I learn they are out of stock of the correct batteries.  
The suggestion that I accept the wrong batteries saves them any expense for their mistake, i.e., the cost of return for the wrong batteries and the cost for shipping the correct batteries. The R2U batteries are more expensive than the wrong ones sent and no offer was made to refund any price difference.  
The suggestion that I wait until 01/31/09 for an exchange and to just hang onto but not use the wrong batteries is unconscionable. For a Company whose primary business is selling batteries, the inability to replenish normal stock for two months indicates a severe problem  

Only buy from this company if you are willing to accept something that you did not order.They will do the old bait and switch and if and when you can actually get a response from them,they will tell you to send back the wrong items at your own expense.Terrible company!!!!!

On 11/30/08, I ordered a pack of 16 AA ready-to-use batteries and a travel charger from All-Battery. They sent me regular AA NiMh batteries and a different charger without any notification. After emailing the company they were reluctant to pay return shipping. Will never purchase anything from this store again.

I ordered 2300mah Ready To Use (R2U) batteries. They shipped 2600mah Ni-Mh regular batteries that have received extremely poor reviews on the web. I have seen other postings on SlickDeals that others have also received this intentional substition. This is bait and switch. Advertise new desirable batteries, then ship poorly rated batteries that no one wants. Unbelievable.

Bought a battery charger. Used only a few times and it failed. In fact, internals melted and smoke came out! I filed case with Fed consumers affair department for potential product safety hazard. When I contacted the company they said past 6 month they won't do anything, not even provide paid repair service.  
Stay away; buy a Maha or at least a major brand that offers repair service.

I have been using rechargeable batteries for many years. With two young children and lots of battery-powered toys, I found that I needed more batteries. One problem with nickel metal hydride (NiMH) batteries is that they "self discharge" fairly quickly. Depending on the brand, they can be 25% discharged within a few weeks, 50% discharged within a couple of months and fully discharged within half a year. Therefore, I have put a lot of time into researching "low discharge" NiMH batteries. Sanyo Eneloop are one of the most popular, but they typically cost about $3.00 per AA battery. As I was planning on buying at least a couple dozen batteries - I wanted to find something that works well and is inexpensive.  
 
After doing some research on the Internet, I discovered All-Battery. Some reviews I read were favorable - while others were not as positive (particularly in regards to customer service). I placed an order through their eBay store (http://stores.ebay.com/All-Battery-Center) for 24 AA and 12 AAA "Tenergy Ready to Use (R2U)" batteries. Including shipping/handling the AA and AAA batteries each cost about $1.70 each - and both have a higher capacity than Sanyo Eneloop batteries. I also ordered one LED flashlight and two LED headlamps.  
 
All the items were delivered just three days after ordering. There was a minor issue with one of the headlamps, but a replacement headlamp was immediately shipped out (and is working just great). I am extremely happy with the excellent service that I received, particularly with how a problem with the order was immediately resolved. My overall opinion is that although All-Battery may have had some customer service issues in the past, that they are working very hard to resolve them. Their high positive feedback score on eBay is a testament to this!  
 
I did some extensive testing of the Tenergy R2U batteries. I tested some of the batteries right out of the package. They did not have much of a charge left in them. This is likely due to either: [1] not being fully charged at the factory when manufactured, and/or [2] sitting in a package for a long time (more than a year) so that some "self discharge" had occurred. I have a La Crosse BC-900 battery charger which is capable of testing the actual capacity of rechargeable batteries (by fully charging then discharging the battery). It also has a very useful refresh mode - which discharges and recharges up to 20 cycles or until rechargeable battery is refreshed to full capacity. New NiMH batteries greatly benefit from being refreshed to gain maximum charge capacity.  
 
For example, Tenergy R2U AA batteries are rated at 2300 mAh. Initial test results for 4 R2U AA batteries were: 1943, 1930, 2020, 1159 (charging at 500 mA, discharging at 250 mA) for an average of 1763. The same 4 batteries after being refreshed three times were: 2340, 2310, 2200, 2290 (same charge/discharge current) for an average of 2285. This is very close to the rated capacity of 2300 mAh! I have at least six other brands of AA batteries that I have tested (rated from 2000 mAh to 2600 mAh). Most of these AA batteries have a actual capacity that is 10% to 15% lower than the advertised capacity.  
 
Tenergy R2U AAA batteries are rated at 1000 mAh. Initial test results for 3 R2U AAA batteries Tenergy R2U AA batteries were: 787, 782, 813 (charging at 500 mA, discharging at 250 mA) for an average of 794. The same 3 batteries after being refreshed two times were: 834, 822, 848 (same charge/discharge current) for an average of 835. This is about 15% lower than the rated capacity of 1000 mAh ... however is still a good result when compared with other AAA NiMH batteries. I have at least three other brands of AAA batteries that I have tested (rated from 800 mAh to 1000 mAh). Most of these AAA batteries have a actual capacity that is 20% lower than the advertised capacity.  
 
I haven't owned these R2U batteries long enough to thoroughly test the "slow discharge" capability ... perhaps I'll be able to update this review sometime in the future. :-) As for the flashlight and headlamps - I'm very happy with them. They are incredibly bright (compared to other LED flashlights that I have) and durable. In fact, I like them so much I just ordered some more!

he price was competitive and the service was great. I ordered the wrong battery pack and had very prompt and courteous help in getting my error corrected. I will be a their customer from now on

My purchase of the latest-technology lithium polymer batteries from All-Battery.com went seamlessly. I received my shipment even earlier than anticipated and the batteries work great! Plus I got free shipping on my next order. I will buy from them again for sure, and would recommend them to anyone. A++.

I have ordered quite a few batteries from All-Battery, including AAA, AA, C, D, and 9V sizes. Overall, my experience has been extremely positive, and I would highly recommend ordering from All-Battery. Below are a few comments:  
* Batteries are cheap and have high capacity. In fact, after some internet comparison shopping, they're by far the best battery deal I've found.  
* Unlike some other reviewers, I've found their batteries to be standard sized so that they fit all of the uses I've wanted them for.  
* Shipping is fast. Communication is great about receipt of order information, and notifaction of shipment.  
* I once ordered way too many C batteries. When I called to return them, I was immediately connected to an actual person, who was helpful and courteous. Returning them was fast and easy, and my credit card was refunded in a reasonably prompt way. When I called to inquire about the refund after a couple days, the person I spoke with told me the exact day the refund would be forthcoming, and he was correct.  
* My one suggestion for improvement is in the packaging. Most of the time, the batteries have come well-padded and packaged adequately. However, on a couple ocassions, they have been not padded at all -- I just ordered 5 D cells that had zero packaging around them at all -- they were just put in an unpadded manila envelope. We'll see if they work. I once had a 9V battery not work from them because (I think) of poor packaging. However, overall, the packaging has struck me as sufficient -- this has just been a single occurrence when they haven't worked.  
* I also have purchased a battery charger from All-Battery, and thus far I've been pleased and impressed with it. This will be my 3rd rechargeable battery charger, but it seems like it's the most versatile, intelligent, and reaosnably fast.  
 
My school also uses rechargeable batteries from them -- lots and lots and lots of batteries from them. They are used in our physics lab as well as in the tech department for cameras. Both departments have had a great track record with them. The tech support person told me that occasionally they will get a bad batch of batteries that don't hold a charge well, but that's the exception not the rule.  
As I previously mentioned, I would highly recommend them to anyone. Oh, one word of advice: google for coupons, because you can almost always find coupons for free shipping.

Tenergy NiMH Batteries Have Nonstandard Size and Unacceptable No-Load Discharge Rate. I purchased two dozen AA NiMH batteries from All-Battery.com in an ebay auction on January 19, 2008 for home use. Twelve were to be for me and twelve for a friend. I purchased these specifically, because the price was good and they came in a package deal, including C and D adapters. The adapters seemed like a good idea for three reasons. 1) you need fewer types of batteries on hand, to always have charged AA, C and D cells, 2) most chargers are only for AAA and AA cells and 3) true high capacity C and D NiMH batteries are very expensive, and the cheaper ones are really just AA batteries in a larger shell. This was fine, because the particular uses for C and D cells that we have, Roomba virtual walls, are low drain and the more rapid turnover for the AA batteries would be acceptable.  
 
Upon receiving the batteries, I charged all twelve of mine and tried them out. It turned out that they did not work in my Cateye LED bike light or in the controller for my radio-controlled helicopter, two main reasons I needed them. Comparing them with other AA batteries, it seems that the problem is that the positive terminal of the Tenergy batteries stands a little less proud from the body than the others, and the aforementioned devices happened to have plastic bosses around the positive terminals, so that the positive terminals of the batteries could not reach those of the devices. I contacted All-Battery.com about this, and they referred me to Tenergy for technical support. The Tenergy tech support person assured me that the batteries met the IEC specification and offered me a 50% refund. It was not clear if I had to send the batteries back and only 50% of my money would be refunded or they would refund 50% of the money without taking the batteries back, but I didn’t clarify this, as I thought I might add a little solder to the terminals to make them work – I did not get a chance to try that.  
 
Fig. 1: Photos of the positive terminals of a Tenergy AA cell (left) and and Ultra AA cell over a mm scale. The positive terminal of the Tenergy cell is just about 1 mm proud of the shoulder, while that of the Ultra cell is significantly longer. The shorter terminal on the Tenergy cell prevents it from functioning in some devices.  
 
 
In the applications where the batteries did work, they seemed OK initially, but lost their charge very rapidly. My friend tried newly-charged ones in her Roomba virtual walls one day and they worked, but a few days later they did not. She also put them in her wireless computer keyboards, but they only lasted a couple of days, while other brands last several months. I put a newly charged pair in my etrex GPS one weekend and went on a hike, but the next weekend they were dead. It seemed that the batteries were running down very fast between charges, so I decided to do a test. I charged 12 batteries and measured the voltages. I found that the voltages were lower than the other NiMH batteries I had (Sony and Ultra). I also found that they discharged faster than other batteries and were very weak after one week. I unfortunately lost that data, but I wrote to All-Battery.com and Tenergy again, asking for a complete refund. They never answered my email, so I decided to do another test and write this review.  
 
I charged 12 Tenergy cells and 2 Ultra cells. The Tenergy cells were bought January 19th 2008 and the Ultra cells were at least two years old but in excellent condition. I had bought them from Globalcomputer.com. I measured the no-load voltage of all cells immediately after charging and a couple of times over the next three weeks. The results for all 14 cells are plotted individually in the graph below. Even at time zero, all Tenergy cells had significantly lower voltage than the Ultra cells, by 68 mV on average, and the discharge rate was much greater, so that after three weeks, the Tenergy cells were on average 190 mV lower than the Ultra cells. After the three week measurements I tested pairs of batteries in a 2-cell Maglite. The Ultra cells lit the bulb brightly with no noticeable decrease during half an hour of continuous operation. On the other hand, all six pairs of tenergy cells produced a very dim light that extinguished completely within 30 seconds.  
 
In conclusion, the Tenergy cells I received are defective in three ways. 1) they have a nonstandard positive terminal size that makes them unserviceable in some devices. 2) the fully charged voltage is lower than that of other NiMH cells and 3) The no-load discharge rate is much higher than that of other brands. I can’t see how any customer could be satisifed with this performance. I think that I may have gotten a bad batch or the comments from satisfied Tenergy customers I have seen on their site were from customers who had just tried their batteries after charging them. In either case, it is unacceptable.  
 

Speedy delivery. I was thinking the price was too good to be true, but the batteries seem to be as advertised and they arrived promptly. As a bonus, I managed to find a great package deal and a discount code via fatwallet.com  
 
I'd buy from them again.

At first I was upset because there was an issue with the PayPal payment but they apologized and gave me free upgraded shipping. Order arrived in 3 days which is acceptible I would recommend this company to anyone.

I ordered smart universal charger upc 8000104.The charger that i received did not worked properly. I sent it back, they shipped a replacement and it does not work either. Here it is april 24 with a charger that does not work. I have purchased batteries from these people i had to send them back also....

In early March, I purchased a replacement battery pack for my Roomba from all-battery.com  
 
iRobot charges $60+ for a battery, and therefore many companies have begun selling cheaper replacement "battery packs".  
Basically, you take the screws out of the proprietary roomba battery and remove the contents (a 14.4V NiMH battery pack) and replace it with the new battery pack you have.  
 
This is the item I ordered: http://www.all-battery.com/index.asp?PageAction=VIEWPROD&ProdID=1035  
 
At the time that I placed the order, it was indicated to be in stock.  
I placed the order on the 7th, and received an email that the order had shipped on the 8th.  
 
Strangely.... I received an email from them on the 10th saying that the item was in fact NOT in stock, and that it was back ordered until March 20th.  
 
They gave me the opportunity to cancel the order, but I asked them to ship the battery when they got it back in stock - which they did.  
 
I received the battery on March 25th. As described, it came with the screwdriver (necessary because iRobot uses a strange triangle shaped screw that you can't remove with typical screwdrivers).  
 
The tenergy battery (their brand) works very well so far. Using the screwdriver and the instruction on the page for the battery, it was relatively simple to install.  
 
So, In short, they did sell me an out of stock item, but customer service took care of things and everything went smoothly after that.  
Overall a positive experience.

I ordered 101 double-A batteries and was sent 111 triple-A batteries. Not only was the quantity incorrect, but the type of battery was incorrect. After I finally got someone to respond to me, they mailed me a sticker to send the package back to them. They refuse to refund the full purchase price back to me saying that it's against their policy to refund the shipping costs. I am not giving up and will report to the BBB and my credit card if they continue to refuse to refund my money. Since it's only $10 that I'm out for shipping, it's not a huge deal, but enough to convince me to never work with this company ever again.  
4/3/2008 update - They agreed to refund my shipping charges so I am now happy. It was a trying time, but they have finally satisfied me.
