go on then battery charge type knowledge typses of the forum

[bertie]

Use an old fashioned charger that does not sense the battery type, stick it on 12 volts and leave for four or five hours. Older batteries sometimes don't fullfill the requirements of fancy chrgers. But they still charge up and start cars.

it may be 'piss taking' but there's plenty of info on t'net about regenerating batteries that wont charge by removing crystallization or resetting ni-cad memory.using a 240v zap

Ignore him Bertie, it'll be fine. Can you video you doing it for the Darwin Awards, though?

Edited for likely outcome .


I really don't know, to be honest. But I strongly suspect that connecting a 12V lead-acid battery to 240VAC could well cause it to overheat, melt, explode, spray acid in all directions, or a combination of the above.

240V ??!!!! I've done it with 24VDC on a 12V and it worked. I believe it's more to do with the current than the voltage. I would definitely not connect 240V to a battery - besides which, it's AC, which I think defeats the object.

240V can stop your heart - don't fuck with mains electricity for the sake of a battery - it's simply not worth the risk.

been on the the old style charger for past 2 hours, changed it to the smart charger and its kicked onto bike and is now charging fine...

strange, smart charger destructions says it can charge up dead/new batts.. I won't be counting on it though.
