I was given an NP213 21.6v cordless, used condition, about 2 years ago. The drill itself is in great condition, but the battery has developed a short memory. The difficulty is getting hold of a 21.6v battery. I emailed Enigma
These packs are generally made from standard cells. Its sounds as if this pack has 18 cells.
Have you considered taking it apart and re-celling it yourself?

If you are stuck, could you not open the unit up and re cell it? The problem might also be due to the cells growing internal whiskers, which short them out. You can recover these to some extent, by charging up a large capacitor and discharging it across an internally shorted cell. The idea is it blows the whisker away, like blowing a fuse.
You can get new cells from companies such as Strikalight.
Likely to cost more than buying a complete new drill.
But dunno what an 'NP213' is anyway.

This could be the way Enigma (above) recon them. I'd rather pay a tenner for a recon, rather than take one apart. The problem is, Enigma don't know if the 24v or their 18v will fit mine. I suspect my 21.6v model, wasn't meant for the UK market, as there's no mention of it on Google. I'll have a look at Strikalight - thanks.
Yes my father-in-law has the same problem, Can't even find the manufacturer. ....Who makes them,..? Help please
manufacturer. ....Who makes them,..? Help please
Ahem! What was the question?

Drill batteries are standard batteries in casings specific to the manufacturer of the drill.

Depends what you mean by standard. For a start, they come in a variety of capacities. Then they could be Ni-Cad, NiMH, or Li-ion. And the case is generally Sub-C size - which you can't buy in the average shop.
Oh - and then there's the quality of the cells. This varies enormously.
