A couple years back I removed a corroded & leaky Varta NiCd battery from my 486 and replaced it with a Lithium Ion coin cell. I used two simple wires to move it off-board to guard against any future damage.
I'm not too pleased with the performance, 2 years into it the battery seems to not charge very well and has a short life of just a few months. Even at the low power drain of a CMOS clock. Internal resistance.. Cheap china crap, you know..
Looking for suggestions for replacement. I want it to stay rechargeable (trickle charge). I heard good and bad things about SuperCapacitors. I was also wondering about using a 3.6v NiMH batt. But I hear they self-discharge. And are still expensive at $8.00 a pop.
Suggestions and discuss please?
