KrataxRechargeable Lithium AA Batteries 3500mWh 4 Count and AAA Lithium ion Batteries 1100mWh 4 Count with Fast Charger for 1.5V Lithium Rechargeable Batteries, for Xbox Controller, Toys, Flashlight

I’ve bought several of these, aaa and aa. One of these batteries is equal to buying 1600 batteries. They aren’t cheap but do the math. I’ve had mine over a year with zero issues. With all the remotes in my house and some small flashlights I was sick of buying batteries every time I turned around. I bought enough to keep some spares charged up so there’s no wait for fresh batteries. It doesn’t take long to more than pay for them selves.

Bought to operate a wifi irrigation controller that was going through batteries like crazy. These batteries seem to last much longer. I am very happy, so far.Using the batteries in other wifi enabled devices that previously required frequent battery changes.

At this point, I have built up a group of (2) Kratax AA/AAA charger/batt combos and several 9 volt batteries with a charger. My AA and 9V rechargeable batteries and chargers from Kratax have been reliable so far.Unfortunately, my first purchase of Kratax AAA batteries arrived not only with a failed battery (and 0 volts on arrival), but it had leaked smelly brownish fluid which had dried to a sticky state as well. The remaining 3 AAA batteries are in apparently good physical shape.The initial charge cycle for the remaining AAA batteries seems to have worked, but the indicator led's between the charger and battery B+ terminals really didn't agree with each other. The AA batteries and same charger from the same shipment has no issues.I have provided a pic of the bad AAA in case anyone is curious.Perhaps it is a better idea to stick with disposable batteries for the next few years, at least on the lithium front.Seller reached out to offer replacement cells...2 for the single dud. Nothing mentioned about inconsistent charger behavior. Good enough.

I have been looking for Li-Ion AA rechargeable batteries for awhile. This look like a good value as it provides more power and longer lasting than available nickel metal hydride batteries. A charger was included and the AAA batteries was an added bonus.

In a typical flashlight these batteries last as long or longer than a standard alkaline battery.

Upon receiving the Kratax battery and charger combo, I proceeded to charge the batteries for the first time and noticed that two of the AAA batteries would not take a charge. Prior to charging, I made sure that the batteries were fully discharged, as this can sometimes be an issue with some rechargeable "smart" batteries. I contacted Hixon (Kratax distributor) customer service and they promptly sent two replacement batteries. In the interim, all four of the AA batteries then began to act up.After trying the charged AA's in my camera flash, they cycled the flash two times before dying. When placed in the factory charger, the charging lights simply blinked and the batteries would not accept a charge. The problem is not in the charger, as it managed to charge the AAA batteries without any problems. While I am sure that Hixon (Kratax) customer service would replace the defective AA cells, I opted to return the entire combo set as I do not have time to deal with persistently faulty products.Hixon/Kratax customer service was great, but their products are rubbish.

The media could not be loaded. Well, I love the batteries (except they have hard time getting inside 2aa mini maglitw, but it is a maglite problem. It also has trouble with some nimh battwries.)3 months into this now, and 2 aa batteries have died (that's the only way to put it.) One battery reads zero volts and when put into the charger, it does nothing. No lights at all, not on the slot or on the top of the battery. The second bad one reads zero volts but when it is put into the charger, the slot shows red (like it is supposed to) and the light on top of the battery flashes real quick, not steady like all the other aa batteries. Then about 2-3 minutes later, the red light will turn green. When you take it out of the charger and test it, no volts out.I have purchased 3 of these combos (4aa and 4aaa with charger) and the rest of them seem to be functioning, but I am sure for how long.I hope your luck is better.

I wanted some rechargeable batteries for some special devices I have, like my left handed trackball mouse, that do not come with rechargeable options. It works great so far.
