This cheap and easy to build nicd/nimh battery charger is suitable for automatically charging a wide range of batteries for many applications. proper chargers are usually expensive and cheap chargers supplied with the original equipment often incorrectly charge the cells and dramatically shorten their life.. Batteries play an important role in any battery operated project/products. rechargeable batteries are expensive, as we need to buy battery charger along with.... The charger in this project is designed to charge two aa nimh or nicd cells of any capacity (as long as they are the same) at about 470ma. it will charge 700mah nicds in about 1.5 hours, 1500mah nimhs in about 3.5 hours, and 2500mah nimhs in about 5.5 hours..
This is fully automatic battery charger circuit using lm311, when battery voltage is lower, it will power to battery then stop when full battery only. Nimh battery pack: 4.8v 800mah nimh (aaa) rc battery packs with optional terminals. Battery charger circuits - battery chargers - find out thousand's of electronic circuits & hobby projects, microcontroller based projects, schematics, electronic tutorials, electronic for beginners, intermediate electronics, science hobbyist, engineering projects, electronic resources to find out quick solution for electronic design problems.
