Hi guys , do any of you know a good place to get a replacement battery for my Bosch cordless drill? I have seen a few places online but I don't know if they are any good , that's why I'm looking for recommendations .

If you don't mind paying Bosch prices, order direct from them. At least you know you are dealing with the organ grinder then so to speak.

for my works Bosch cordless power tools and batteries. I don't know if you use their professional li-ion range or if it's the DIY range. Anyway, they are pretty cheap either way.

Try Screwfix. CPC might do them also. You might find somewhere has an offer on that makes it cheaper to buy a new drill than a battery. Black MY2013 SD4 GS Auto, Wood Company Armrest, Freel2 sticker.

I bought a Bosch cordless hedge trimmer about 2 years ago that came with 2 14.4v ni-cad batteries... disappointed with their life despite using them regularly (I bought a second hand drill and torch that used the same battery off ebay). Replaced with a pattern battery off ebay with a higher capacity (2000mAh) and it has been brilliant. Cost £21 inc delivery. Even if this battery lasts as long as the originals, it represents good value compared to the Bosch ones. 2016 BMW X3 30d SE in red
