AAA Rechargeable Batteries by AmpTorrent - Power Your Devices for Longer!

Glynn: I have smart door locks that use a lot of AA batteries as well as smoke detectors that also use AAs. I used to buy AA batteries in bulk on an annual basis but since buying Amp Torrent 3000mw AAs plus enough to have 4 chaging at my desk I now have a glut of conventional AAs that I have no idea of what to do with. At least I can get some of the conventional AAs used in holiday decorations.

CM: I usually do not take the time to write reviews… but was compelled to do so in this case. A couple of months ago. I ordered two 4-packs of the batteries. I did not charge them right away, as I was using up my supply of disposable batteries first. When it came time to use the batteries, I plugged them in to charge. It was then that I noticed one of the batteries would not charge. I contacted support, and they got back to me and immediately shipped a replacement. When the package arrived, there were actually two batteries in the package. Over and beyond my expectations!!!! Who does that in this current day? Thank you for the exceptional customer service after the purchase!!! 

Alvin LeeAlvin Lee: I bought a set of four back in end March 2023 and used them in a low-power kitchen scale, changing them about once a month. The four batteries cycled two times in the four months since receiving. During charging in August 2023, one of the batteries was burning to the touch and couldn't charge. The heat melted the label due to the high temperature. I contacted AmpTorrent's support (on AmpTorrent's website, the link in the Amazon description was broken) and the support promptly arranged a set of two replacement batteries. Overall, I'm very impressed by AmpTorrent's support but I'm a little wary of these batteries suddenly failing.

As for this class of batteries, I'd say they fill the niche for the small number of devices that strictly require above 1.2V to operate. These include my aforementioned kitchen scale and a laser pointer. Otherwise, LSD NiMH batteries would be my main pool of rechargeable batteries. One particular advantage this model of li-ion battery has is the ability to accept mini USB-B so you don't have to carry a bulky charger, especially when travelling.

JWJW: Update: AmpTORRENT was paying attention to the product reviews and has updated their advertisement to correctly indicate the cell discharge current. So, +1 star for being a good and responsive company!

AmpTORRENT AA cells provide a regulated 5VDC output and are very reliable.

However, the ad copy on Amazon says "Maximum Discharge Current: 2A". This makes sense as the maximum continuous discharge current of an alkaline AA cell is approximately 2A. This would indicate that the AmpTORRENT AA cells are direct replacements for AA cells.

I put three AmpTORRENT AA cells into a AA powered LED light. That light is rated for 4.5V at 1.7A. Three series AmpTORRENT AA cells should be able to provide 4.5V at 2A according to the advertisement on Amazon. Shortly after turning the light on it started to dim. Given the AmpTORRENT cells are regulated, this is unexpected. Upon further investigation I found the AA cells to be hot to the touch. Digging out a magnifying glass, I found the text "Model: ATM2960 | Type: AA | Cap.: 2000mAh | Max Discharge: 1.5A | Made in China" on the cells.

Clearly, the 2A maximum discharge current advertised on Amazon is not...

Joe °: Great batteries for my purposes! I have a small pen light that emits UV light which I use to spot cure UV reactive resins like LOCA and those made for jewelry making and crafts. The intensity of the pen light is higher than most so it saps up the juice from two AAA batteries in about 20 minutes. With these Li-Ion rechargeable batteries, I get a higher intensity beam compared to NIMH batteries and they last longer too. I'd even go so far as to say that they work as well if not better than alkaline batteries. With the quick charge, I can use one pair in my pen light while the other pair charges. By the time the ones in use drain, the other pair is charged so I can essentially swap then out without wasting batteries and time. I don't know how many cycles they'll be able to handle, but so far they've already been a time and money saver compared to lower voltage NIMH batteries that have a longer charging time and are more cost effective than non rechargeable alkalines.
