Pack of 4. Economical and environmentally friendly, ready to use batteries. Rechargeable up to 500 times, and compatible with any standard battery charger. 5-year battery life.
These are the type that retain their charge if not used, so 800mAh is about the norm.
A far better buy than the misery types on Ebay - or the dubiously rated BTY brand that appears to claim twice the battery's actual capacities.
There are 120 Screwfixes distributed about the country for you to pop into to buy these - but if you do decide to have them delivered the postage is a rather prohibitive fiver on sales under fifty quid. So its only really worth visiting to buy these or to use them to up an order over the free delivery threshold. If you do - then there is quidco at 6% too.
