With the increase in the demand for 9V PP3 batteries, there is a significant need for an efficient charger. One might be able to find several PP3 batteries that are manufactured majority being NiMH, however, there is an alternative of Li-Ion batteries.
This has made it difficult to get a suitable charger for your rechargeable PP3 batteries. Some battery chargers provide 7.2V up to 9.6V but are limited to certain battery chemistry. This new product, MintyCharger, is an invention to solve this confusion and chaos. For those looking for a single battery charger that can work on every single PP3 battery out there in the market, this will work seamlessly through its compact form fact.
There are several things that you can look for while buying a battery charger for your 9V PP3 batteries, one of which is avoidance of overcharging of batteries. To resolve this, MintyCharger comes with a refresh function that allows the hardware to perform a full discharge/charge cycle. This helps to improve battery life when several chargers in the market abuse them by over-discharge. Looking at the internals of this battery charger, we noticed that it works on the Microchip PIC16F18325-I/SL as the main controller. With this 8-bit microcontroller getting 14KB flash memory is capable of supplying 7.2V, 8.4V, 9.6V outputs for NiMH batteries while 7.4V for Li-Ion batteries.
