My trusty old Wicks cordless drill has a failed battery. The other one is still ok - but won't be far behind. It's a drill I like - has an add on right angle drive attachment, so I think it is worth fixing. Wicks don't do spare batteries and it's an odd size - 15.6v 2Ah NiCad. The cells are definitely Sub C size.
I'd be happy to replace them myself using tagged ones. But where to buy decent ones at a good price? Or would a firm that fixes any battery be a better bet? It's quite a few years since I bought any cells like this, so any up to date info appreciated.
