Be gentle with me, this is my first post!
Bought one of these from my local Maplin store in Chester the other day.

These AlwaysReady nickel metal hydride rechargeable batteries offer amazing value for money. Up to 1,000 charge/discharge cycles can be expected and a single charge outlasts most standard alkaline batteries. This makes these the ideal choice for today’s battery-hungry digital devices such as digital cameras, MP3 players, hand-held games etc.
These AlwaysReady™ batteries come pre-charged so can be used straight out of the pack – no need to wait for them to charge. They also have a very low discharge rate and will hold their charge for up to 1 year.
