on nicads - db (martinez, ca.) - 08-05-2010 from the font of all knowledge: Re: on nicads - Vieira, Luiz C. (Brazil) - 08-06-2010 Hi, db; all I'd add about that is something mentioned by Katie Wasserman a couple of weeks ago: NiMH cells work better/live longer if kept charged at 60% +/-15% of their full charge, based on Prius battery regulation. Please, follow this thread; Katie's is one of the last two. I sometimes find only NiCad's when searching for certain types, like the ones to rebuild the 82143A batteries (and related cases: Topcats, 82162A, etc.). I never found NiMH Sub-C batteries where I searched for them. Cheers. Luiz (Brazil)

NiMH Sub-C batteries - tim m. - 08-06-2010 I've bought many from BatterySpace.com, mainly for rebuilding Roomba battery packs (with 12 cells in series, usually one or two die, bringing down the entire pack voltage enough that I get very little operating time from the robot).

Re: NiMH Sub-C batteries - designnut - 08-06-2010 I have hadsuch good reesults with Sanyo Eneloop low discharge AA cells I use them in most appliances. I used to have 2 4 station chargers on nearly full time, now one used rarely. I read there has been further improvement lately in the self discharge rate. |
