BOSCH STARTER SET CONSISTING OF 2 X GBA 18 V 4.0 AH M-C + AL 1860 CV 1600A002F9 - Free delivery
These are the professional series batteries for use with the blue tools.
2x 18v 4.0AH batteries and charger.
Good price at £109.99 with free delivery. Best deal I could find, currently £219.99 at Screwfix. Which is a bit much, batteries are worth £50 each and the charger around £30 if you shop around. Screwfix want £89.99 per battery.
This is the first time I've used campbell miller tools but I was impressed with the professional service. This was delivered within a couple of days via DPD.
Hope it helps. Goes well with the cheap Bosch professional Impact driver posted recently on Amazon at £60.
