Hixon 1.5V Rechargeable Batteries Lithium AAA 1100mWh High-Capacity Long-Lasting Triple AAA Li-ion Battery 12Counts,1600 Cycles,Constant Output(No Charger)

Tried to expand my rechargeable battery arsenal so I picked up a set of these. I picked these over the LiIon batteries with a microUSB/TypeC charger slot as these Hixons do house a larger battery without the slot. They also appear to be a better build/brand than many of the other cheap Chinese equivalents out there.Cons: Not quite close to their rated capacity. At a 500mAh draw, the AA's made it to 2100 mAh (about 3150 mWh's, not 3500), and the AAA's made it only to 570 (830 mWh, not 1100). The AAA's won't supply as much total current as their alkaline or NiMH equivalent. Price per battery is much higher than that of NiMH. Charger requires you to plug it into USB power before connecting the batteries (more of a nuisance). At the 1.5volts that these run at, they could be good for flashlights, however, they get too hot when used at a high discharge for too long due to the buck converter circuit inside. If used in a flashlight, i recommend only intermittent use to reduce overheating batteries.Pros: The AA's have about the same amperage output as their NiMH or Alkaline equivalents. The cells hold a constant 1.5volts throughout their whole life, only briefly dropping to 1.1v, then shutting off the circuit upon being dead, nice feature for some applications. Lighter than Alkaline or NiMH. Easy and quick to charge.Summary: Until these style batteries can either increase their capacity or reduce their cost, they likely won't be competing with NiMH rechargeables for 80% of use cases anytime soon. For the 20% - some electronics require or perform better at higher voltages (Smart locks, RC cars, wireless controllers to maximize range, anything with a motor, etc.), so I'd recommend buying a set of these for those specific electronics, and sticking with NiMH for everything else. DO NOT: recharge these via any charger other than the one supplied with the batteries, they require a 5V input regulated by the Hixon charger.

Why has it taken so long to have regular sized batteries in rechargeable Li-ion? We have all used and abandoned the crap alternative Ni-metal or cadmium rechargeable ones because of short life. We have landfills full of disposable batteries when we have had the tech to make this for the last 10+ years.

Use and toss batteries are so expensive! I can now use these instead and save a lot of money and also no worries for polluting the environment since they will last for years. I have them in some battery operated devices for a couple of months and love the way they hold charge and save me money long term.

These batteries came without charge. No voltage measured. They were placed on the charger that came with the batteries. They took the charge. Stored them for future use. Six months later, when I took them out to use, they all are dead, now.

Doesn't last as long as non-rechargeable batteries but in the long run is cheaper.

These batteries act like new batteries for a long time in whatever you use them in and they last a long time. They recharge in about 2 hours and then it's like you have brand new batteries again. Regular rechargeable batteries are not like that. I recommend these batteries. Make sure you get the right charger. It won't work with a normal rechargeable charger

These are fantastic because they are full 1.5 volt so you can use them anywhere.. will never buy anything else these...

The AAA batteries I received do not hold a charge for very long. The AA batteries work fine and the stored batteries have been holding a charge as described. I am doing a test to see exactly how long the AAA (triple A) batteries are holding a charge. I was disappointed after charging the batteries and the alkaline batteries in a remote finally went. Put two Hixon 1.5V Rechargeable Lithium AAA Batteries in and nothing. Checked the batteries and they were dead.
