Allmax AAA Maximum Power Precharged Rechargeable Triple A Batteries (8 Count) – Ultra Long-Lasting, Recharge up to 2,000 Times – 1.2V

I purchased the AA size 12 pack option and immediately tested all 12 via "Discharge Test" mode on my IQ 338XL charger/conditioner. I'm pleased to report all (slightly) exceeded the advertised 2,000mAh rating right out of the carton which is a good sign. Generally NiMH cells need to be fully cycled several times when new in order to achieve max energy output, being that these cells have exceeded advertised energy output with no cycling/straight out of the box is commendable. No duds in 12 pack of AA's. FWIW- I also recently purchased the 12 pack of AllMax AAA size cells and they all also exceeded their advertised energy rating of 800mAh right out of the box. One way to look in to a cell's overall "health" is to look at it's internal resistance when charging. Cheap/junk (think dollar store brands) cells have higher internal resistance, also cells that have aged or have been abused by being too deeply discharged or charged or discharged too fast show higher internal resistance over time. I have some Fujitsu and genuine Enloop cells (both manufactured in Japan) that are from 2015/2016 and still exceed rated mAh output and their internal resistance is in the 50+ milli-ohms range range at this point. All the AllMax AA cells, including the AAA cells I purchased earlier measured in teens to mid 20's milli-ohms range out of the box... so another good sign that these are good quality cells. One last word.. Charging. The last thing you want to do to any cell is cook the cells (overheating them) by charging them too fast at a very high mA rate relative to their size. An AAA size cell can not handle the same charge current rate as a much larger C or D cell or even a AA cell. You need to base the charging on the cells rated mAh output not the charger device guessing what rate to use. There is much nerd controversy about charging rates, but most manufactures now state to charge between 0.5 to 1X of the cell's rated mAh capacity. So for these 2,000mAh rated AA's you should be able to safely charge them between 1,100mA to 2,000mA. A good practice is to feel your cell's temperature as they are recharging. If they are getting hot, you need to step down the charging current. I've been charging my Fujitsu 1,950mAh rated cells at a low 500mA rate since 2015 and they still exceed the "as new" advertised mAh rating 8 years later. If your charger has the ability to drop down to 500mA and are not in a hurry to recharge, try using the lower rate as it generates less internal cell heat which lengthens the cell's usable life. For the small 800mAh rated AAA cells, 500mA charging seems a bit too high for my liking. I like to charge them at 300mA if I can as this prevents them from getting hot during charging. I also have several 7-8 year old AAA's that are still performing at advertised output, I think that is mostly due to charging them at these lower rates over the years. In the end, there is no real way to determine how well these AllMax cells will age, but their specs are good right out of the box during testing.. so they are off to a good start at least!

These batteries work well on my landline phones so far. I can't take any pictures or videos of them at work to show you, so I didn't, but just take my word for it, OK? My word is good, believe me, but then again I am asking you to trust someone you have never seen before or even met. Now, how dicey is that nowadays? I mean, a dude who you don't know, have never seen or met and never heard of until this moment is asking you to trust him and jump into a possibility of endangering possibly hundreds, if not thousands of dollars of equipment that you might use these batteries in. So, you might have a huge decision to make right now and you have to seriously ask yourself, do I trust him or not? Well, what's it going to be? Sometimes you need to trust your fellow man and go for it! If we all could be honest with one another and ourselves, life would be lovely and so much better living with one another...

The price to performance ration on these is great! The only thing I've noticed while using them is that they need to be charged right out of the box. Also, I've been running the first charge on "refresh" mode with my Opus battery charger to get the full advertised capacity. Otherwise, no complaints.

I use these batteries for wireless headphones for the TV and they seem to hold up fairly well but they will not activate the associated charger while installed in the headphones. I have another charger that will charge them separately out of the headphones but the charger will not turn off when fully charged. I didn't check them too close when I first charged them and when I did they were very hot, checked them with a meter and they were fully charged. The headphone charger and other charger work well with other batteries.

I bought these to replace some aging batteries in my cordless phone handsets and they've been working great and with better longevity than the original batteries when they were new.

I like these pretty god rechargeables to bad you can’t buy them anymore

Soso

I replaced all of the original Panasonic AAA batteries in my cordless phones with these and they work great. Sure, the numbers claimed are inflated but they're still 250% better than the OEM on my DECT phones. You really can't beat the price.
