I have the makita version for my impact and driver combo. I was thinking of buying a spare so will keep and eye on your thread mate in case others have experience of replica batteries.
Hi,
I bought a genuine battery from these people http://www.ffx.co.uk for £24 which was a lot cheaper than most people. I've had mixed results with replica batteries but didn't want to pay £40 for the privilege of a genuine one.
(No connection with this company apart from being a happy customer).
Charged them a few times now .longer running time than Bosch. But they are I.5 amp as to I.3 on the Bosch.so far Gerry pleased with them,time will tell.some of my Bosch batteries have only lasted just over a year.
