"Bought this as a back up for my 18V Makita drill battery. NOTE it's half the capacity of the original (and half the weight) but hopefully keeps me going when the larger one runs out. Worked straight out of the box so no problems there. Can't comment on long term reliability but if it's as good as other Makita products then will be great. As ever great service from screwfix wrt delivery price etc. Used them many times in the past and will definitely use again. Recommended to all. p.s. Used Screwfix via topcashback and order / payment tracked within 10 minutes (unlike some other sites) so alls good there"
