Wait! Before you dis the deal these are a different sort of rechargable battery, they come fully charged and dont loose charge when stored in the same way as other rechargables so are a big step up from ordinary rechargables!
# Can be used straight after purchase
# Has a high performance
# Long shelf life with no loss of energy
Recharge with your normal charger too.
Edit: Price now dropped to £9.99 for 8 so add something else to get free delivery, or why not buy 16 ;-)
