I've done dummer things....
Yesterday I was manually balancing my new 200 Ah TS pack of 34 cells and SOMEHOW forgot and left a 0.66 ohm load resistor connected to one cell all night (must have been the football game!). It drained that cell down to 1.6V (measured right after I disconnected).
I attached a 4.5V, 500mA wall-wart battery charger to the battery and in 10 minutes, it's now at 2.5 and slowly rising.
I'm curious what best practices are here to try and recover a battery from over discharge. The discharge rate was continuous (3-5 amps or so) if that matters. What should I expect?
Any suggestions? Anyone had any luck with recovering an over discharged battery? Thanks. Tom.
