During a long time, there has been a tangled question - The advantages of disposable and rechargeable batteries incompatible.
Some rechargeable batteries' voltage always drops gradually over time. When the voltage is not high enough to wake the device, a new annoyance arises - the rechargeable battery always seem to fail to achieve the ideal battery life.
The key to solving this problem is how to keep the voltage of the rechargeable battery at a constant level.
Kratax new generation of 1.5V constant voltage output AAA rechargeable batteries is here. Equipped with short-circuit protection, overcharge protection, constant voltage control circuit, etc. - the Kratax laboratory has once again defined the smart chip technology in the battery field
