Re: Battery Clinic follow up & Questions
The way to resolve the question on the sealed pack is as follows:
Determine the capacity of the pack. Example: 2000 Mah.
Determine the charger outputs. Example: Quick charge = 500 Mah. Divide 2000 by 500 = Charge time of 4 hours.
Slow charge = 200 Mah. 2000/200 = charge time of 10 hours.
Connect it to a timer set for 10 hours or 4 hours to prevent overcharge on FULLY DISCHARGED pack. You can make a simple discharge device by wiring 10 12V. 1 to 2 Amp automotive taillight bulbs in series and connect to pack. Just wait until the bulbs no longer light. Your pack sounds like it is Nimh cells. Remember that the slower charge will give you more capacity in the pack, where a quick charge will give you increased initial voltage.
