There's a fundamental problem with rechargeable batteries - they lose charge very quickly when left unused. That means you charge them fully, maybe use them a little, then have to charge them again when you next need them
And that's a problem that Duracell has tried to tackle with the new ActiveCharge range.
Promising to retain around 75% of their charge when left over long periods, they cut down on the power you use by cutting down on the power you lose. (Ooh, I done a rhyme.) I've been using them for the last few months and can vouch for those claims.
I'd love to have time for my Xbox and Wii, but the reality is that they get used less than once a month (unlike my PS3, which is used for DVD/Blu-ray duties, but that's another story altogether).
That means I pick up a Wii controller and I want it to work, which hasn't been a problem since using the ActiveCharge cells.
Hopefully this is going to be the turning point for me and rechargeable batteries. Looking good so far.
