One of the problems with most rechargeable batteries is that they don’t stay charged for extended periods of time. Most batteries will gradually lose their power over just a few weeks if they are not used after charging.
However, Duracell have developed a new range of rechargeable batteries which do not suffer from this problem. They will hold up to 80% of their charge for an entire year after charging, which means they can be stored and instantly used when needed with no fear of loss of performance.
What’s more, they are also sold pre-charged, unlike most rechargeable batteries which must be charged before use, so they can be used straight from the box as and when you need them.
