Camera Cell ?

[bobbill]

Have a L-ion Sony FV 50 I need to re energize...have figured out wiring and have a charger...how long should I charge to jolt, 15 seconds or so? Thanks...lots of dodgers charge to max and let them sit...figure that is wrong...and have this one must have been too low too long.

If the battery is very low, then yes just hook up the charger to it to bump it up to a safe voltage for lets say a few seconds and measure the settled rise in voltage, repeat until safe voltage is reached, like for 18650's would be 2.8V or 3V. Then charge it very slowly, if you can 0.1A charge.

Safer that way, but also less stress on the battery cell, your case a coin cell like watch battery or whatever? Guess I could google L-ion Sony FV 50

6.8V it says. looks like 5 or so contacts.

Whats the voltage at now?
Hopefully its not to low, guessing if 3.4V is half, then 2.5Vx2=5V if its 5V would means its very very low? I dont know. But if it is, just bump it up with quick pulses of charge, wait till settled higher voltage and repeat.

Thanks.
Right now will not charge and have not checked voltage...only two contacts, center is null. Right side is + per this.

Seems most users charge full and let sit...figuring a quick jolt to liven and then to charge to 80 percent.

3 pics are because I am dim...pics are of underside of charger...

Consumer grade products such as Sony have safety features that may not charge. Like some of the tool batteries with their pcb boards will make the battery useless under certain conditions even though the battery itself is fine, its the pcb cutting out the power for safety reasons, hence Sony, Dewalt, Hilti and the like. Watch AvE channel on YT newest video 3 wks ago? on "best battery" he talks about it.

Mark, thanks, thought of that and planned that might be the case. Sony, so me, is not above profit, a dime at a time, like a church or government or politician...I generally expect the worst...

Have not caught the AveE thingy and will look for it.

Stay loose and things will come together.
