Cordless Drill Battery

GB · 2009-10-11T18:54:36+00:00

I have a very decent rechargeable drill that has done good work for the last 6 or 7 years. It came with two batteries which are holding less and less charge. I would quite like to buy replacement batteries, rather than throwing the whole thing away.Looking around these look like Hitachi batteries. Is there any way to find out for sure what batteries to use, or can anyone put new cells in the existing plastic battery case? The drill is badged Detor Power Gold - it's just a sticky paper label - but as I said this drill has been quite a class act, so I'm wondering who actually made it. Otherwise I wouldn't bother.It looks like each battery has about 15 cells in it connected with strips of metal that have been spot welded (or something like that, but well beyond anything I could do anyway).Also, failing that I was wondering about this one as a replacement:- there better/cheaper? I really can't justify spending a lot more, though.

In general, if the capacity is greater than that from a respected manufacturer as listed on their own web site then what is printed on the side of the battery is likely to be a lie.

Yup, it is not uncommon to see ads on ebay etc claiming capacities 3x higher than the best available from the premium brands.

There are some good comparisons here:
