I still use the Dewalt 18V cordless XRP range of tools which I have had for years
As we speak, I am trying to convince 2 of my batteries to take some electricity, but I suspect they've had it.
I'm torn between buying new batts (genuine batts are pricey), or thinking of moving to a new range. Trouble is, I have quite a lot of the XRP type range, so I suspect it'll be Ching Chong batteries for me, and hope they last a year or 2.
The original Dewalt NICAD batteries that powered the tools weren't of a good standard and they lost their charge very quickly and / or wouldn't charge up at all.
I replaced them with a couple of copy / Chinese NIMH batteries which have performed a lot better, but they need careful looking after and if not used , I tried to charge them once a month.
They are now not lasting as long as they did between charges, plus having smashed the case on one when it fell 6' from where I was working >:, I have bought two Li-Ion nano type batteries (no doubt from China) plus a genuine Dewalt li-Ion nano charger for them, and the batteries have been great. Two years or so on, and both are performing very well, power the tools well even under hard use and hold their charge when not in use. They also have the useful charge level status lights. Given the tools a new lease of life!
