Hello,
A few years ago I bought one of those portable jump starters in a sale from Maplin. I think it was this one:
It never got used for jump starting, nor for anything else for that matter, and that's the problem; it got forgotten about in the boot of the car and the battery seems to have died.
It is a 12V, 17AH battery and from limited googling, it seems these are used in mobility scooters, so they should be quite easy to find. So far I am finding them for about £50, which is more than the whole jump starter.
Is it that the manufacturer buys the batteries in bulk and gets a better price, or is it that the manufacturer uses lower quality batteries?
Should I buy a new battery or a new jump charger (or on the basis that it was never used, not buy anything and risk getting a flat battery tomorrow!)
Thanks, Stephen.
