beetlez 0 Report post Posted August 11, 2004 Anyone come across any charging & discharging circuits for NIMH batt? To be more specific, it is for the GP 170mAH 9v battery. Thanks. Share this post Link to post Share on other sites
bpribadi 0 Report post Posted August 12, 2004 I made one long time ago, if I found it, I will post it. Basically there are two methods, constant current (easy to build) and trickle charge which often need micro processor. For constant current, the rule of thumb is 1/10 of the battery capacity. Means if for 170 mAH, you can just feed it with 17-20 mA with voltage about 3-5 volts higher than the battery. Share this post Link to post Share on other sites
