(24 PACK) Amazon Basics Rechargeable AAA NiMH Performance Batteries, 800 mAh

Update 06/26/2025 These don't hold a charge as well as previous sets of Amazon Basics AAAs. When I got them I put some directly in old school wireless phones (Panasonic - see photo. After a full charge in the phones, I noticed "low battery" warnings after only a day or two off the charger. Other brands and previous orders of these lasted 1-2 weeks off the charger before "low battery." I swapped them out for some of the others that I'd "cycled/tested/refreshed" expecting that in testing, sometimes the batteries will hold a bigger charge. Not so with these - same result as the first ones out of the box. Reviews here and personal experience shows a "hit or miss" with these AAAs. I've had two orders with one or two that were weak or dead out of the box and could not be revived or improved. Amazon was great to swap the set out for a new one and those were fine. This is the first set of these that I've gotten with such a low "pre charged" level out of the box and such quick discharge under moderate loads. Today, using a cordless phone, I got the garbled "breaking up" side voice on my end and the other end of the call. This is consistent with worn out batteries I've had that can't deliver enough current to maintain a good connection with the base. I've been using Amazon Basics AAAs for years. In the photo with four different labeled batteries, I have the left one (latest batch) with newer markings and the right one (last year's version) and the two between. The left one is the only one not holding up well. The black and white ones still hold up under a load. Being older, they don't charge to quite the capacity a when new but still doing well enough for every day use. I think I got a bad batch this time. Going to see if I can simply return them. Update 06/18/2025 Good so far. I used a few straight out of the box in some cordless phones. Some phones showed fully charged and some showed only partially charged. The remainder went into chargers to cycle/refresh/test them which took some time and after an overnight of "testing" I did note that some appear to have a higher capacity than others. That said, I have noted similar variability in a single package of 24 previously. This batch did not quite make the 875 mAh that I've seen in previous batches. I like them and as they wear out, I'll buy more but I have noticed they self discharge a bit faster than the big brands and capacity is somewhat variable. On the whole, a good value when they go on sale. PS 06/19/2025 - Having just commented about inconsistencies and lower capacity pictured on my LaCrosse charger, this morning I saw this on my Bluetech (LaCrosse knockoff) charger. Pretty consistent across the board and a little above the claimed capacity. Now, who do I believe? To I believe the knockoff or the brand name charger? Addendum 04/29/2025. Just got another set on a "tax free weekend" and all cycled/refreshed fine and charged to 800-850mAh. No duds. These have always been dependable and I expect the same from this set. Addendum 08-09-2024 - Just took the last two sets of four from the chargers. No duds with the replacement order. After cycling/conditioning them most are showing 875mAh and up [one set in the high 700s but that charger always reads low]. Addendum 08-06-2024 - Just received another 24 pack and this one has four "duds." I like to condition or cycle my batteries before using them. 20 of them worked fine but four of them would not "stay lit" in the charger. All four were from the same little pack of four. I was using a Maha MH-C3000. Two would not start a charge cycle at all. Two others would erratically start a charge cycle such that I could input "refresh/analyze" and then input the charge and discharge currents (I generally use 200 ma for both charge and discharge - low and slow.) I had to wait for the two erratic ones "came on." After waiting 30s to a minute they did start. I tried the slots with some old working batteries and they "came on" immediately in the same slots so - not the charger. Both batteries would eventually come on and I could input refresh and the current levels but would then not stay on. The screen would go back to its appearance when no batteries are inserted. After 5-6 attempts with the erratic ones (more with the two complete duds) I chose to exchange them. I'll still buy these and I have had the occasional dud or two in previous packages but those would eventually start and cycle in the charger and have been dependable enough over time (see below). The four in this set would not even let me get through the first step. Amazon is great at taking things back so I'll still take my chances. More good, than bad but, this was a bad set. PS: I don't use these in high demand situations or in applications where reliability is a concern. For light, everyday use, they are fine. This is first set of fully non chargeable duds. Addendum 05-19-2024 - Just got another 24 pack on a good sale and am starting to use them. In that time I've noticed a continued trend in that these batteries do not last quite as long, charge to the same level, or tolerate a deep discharge as well as other brands. I still think they are a good value for the sale price (otherwise I would not buy them). As long as I can baby them a bit and make sure they do not discharge too low (motion sensor lights too dim) and swap them out a bit more frequently than other brands (Fujitsu, Ladda, Eneloop [Japanese?] and EBL [Chinese?]). I've not started marking the ones purchased last year with dots to indicate the capacity. I add a dot each time the battery falls below a certain amp hour level. I've had a few die altogether and have about eight from last year's sets that are charging to a lower capacity. On a tangential note - I have had good luck with EBL NiCd AAA. PS - they hold up well enough in dollar store solar recharge yard lights. Not as well as the EBL NiCds but some are still going since last June. Addendum 11/27/2023 - I purchased a 24 pack in March '23 and another 24 in June '23. Overall still pleased but the value for price is fading a little. It is now 5 to 8 months later and I'm going to retire two of them as they are now "dead," bringing my total to 3. These last two are giving an error message or null in multiple chargers. In the past, when this has happened usually I've been able to "wake up" the batteries using an Ansmann charger. Not so, today. The total that I can't recharge is 3 out of 48 so, not all that bad, I guess. The ones that I have been able to rejuvenate (around 8 of 48) tend to have a bit lower capacity and are in general "weaker," fading faster than the remainder. The main WARNING here is to not let them drain completely. I've had several drain to a low level and recharge with no problem BUT, if they go dead, it is difficult to bring them back. [I've had a single one go "dead" with the remaining batteries in a light still giving dim light.] If you place them in devices which have a constant drain, don't forget and leave them for extended periods of time. My most recent two were left in a FireTV remote that was used for three days on vacation about a month ago. Light use but left them in the remote. PS - It has been my experience that these do not hold a charge, long term, as well as other Low Self Discharge brands. On the whole, for the price I got, I would buy them again. I now routinely either remove them or rotate them and am having acceptable results. They're fine for everyday use but I would use something else for demanding uses where reliability may be an issue. I was wary but bought because of price per battery. Others here found a couple of "duds" in the mix when they received theirs. I had 4 of the 24 charge weakly the first time with one less than 100 mAh, two less than 400 mAh, and one just over 700 mAh. I placed these back in the charger with the charger set in the "test" (cycle) mode and they all came out over 800 mAh. I had one that on first charge was >900. Overall pleased. Some are going into yard lights and some will go into keyboards, remotes or old Harbor Freight "giveaway" flashlights. Update 06-10-2023. Just bought two more sets of 24 at a really good price. Switching out AAAs in yard lights. I did notice these don't hold up as well as the 1100 mAh EBL nicads in the yard lights. As before, one set had a couple of duds but after a couple of cycles through a smart charger in test mode, they're all >700mAh with most solidly in the 800 mAh range. When this bunch wears out, I'll gladly buy again. Short version. If you get a couple of duds, try putting them in a charger that can "test" or "cycle" them a few times until they come to a full charge - if your charger has that capability. I've used these before and have been pleased with the value.
