Quoting: FUBAR
I may still have some of those, and a charger and some mountings for them in my old (and very dead RC car), they're old but should be fine, i'll check with my mum & see if they've been thrown away, if they haven't they're yours for free
Much appreciated. A pack will certainly be easier to fix long-term . . . .
Good news, though . . . I tested the two remaining Duracells in a torch earlier and they didn't even light the bulb !
That made me think that they were definitely specific-use batteries.
So I threw them away.
Brought some new Duracell "Ultras" at CostCo earlier . . . . .
Ta-Dah ! - It's like Fooking daylight !!!
VERY happy with that.
Just got to fit the battery box somewhere (not a clue atm) and solder in the last couple of wires . . . couple of finishing-off jobs after that and she's done . . . . I have a final, simple, finishing touch to add that I hope works as I plan.
Oh, and here's the second battery that exploded . . . It's not a good pic but you can make out that the (-) end has been blown almost entirely away from the casing . . . . And that's how I found it.
