Unless you want to sacrafice Reliability there is NO other Way. BUT if you don't care about CEll life then go with the 10% of mAH for a starting trickle charge point and make downward adjustments for any cell heating. At a minimum you will need a two step charger. One for the actual charging of the discharged cells and another or the Storage trickle. Rembembering that the cells should bacicly be at room temperature while on Long term trickle charging. BR>My application consists of two parallel banks of 5 cells each (single "A" BR>NiMH pulls, probably from older Laptop packs or similar) for 6 VDC @ 6 AH (y BR>each cell is rated 3.5AH so I'm assuming I can get at least 3 AH each). Wherw dod yuo locate the "A" cell batteries? I don't recal seeing that size. IF yuo mistypes and ment "AA" where did yuo find the 3500 mAH cells. the largest ones I have ran across are 2300. Althouhg they are making advances. In days past 800 was concidered GREAT. BR>I have a Timex Diehard (flashlight that plugs into AC and kicks on BR>automatically when power fails or when it's pulled out for use) that used BR>rechargeable NiCds originally.
