Batteries are usb rechargeable, so you don't need to plug in a charging station. They have 2600mwh which comes out to 1800mah. My door locks and unlocks faster like if there is alkaline batteries. Then just recharge and start over.

They fit perfectly, they align in the holes if the aftermarket cases we bought for his controllers. The connect of the magnetic charger to these got so perfectly.

If you convert this battery's 10,000 mwh to mah, it's only 6666 mah. They last about 50% or less than alkaline equivalent. Charged after purchase and placed in flashlight unused for several months.

Can't charge in standard battery chargers. These are a rip off, unless you're willing to sacrifice almost half of the usable charge, just to avoid having a separate charger.
