Rechargable Batteries.

Santer the thing is I have to take care with the MaH values and ensure everything is straight before doing that - I dont know anyone with the same charger so I cant go that route. I could only be sure if it was the same charger I think. Im not too tech.

Do you know anyone with a charger you could try with the batteries your charger rejects?

As long as it charges the same battery type, you can use any charger

Chargeable batteries are not always the best answer.

The issue is that a non rechargeable is 1.5v where as a rechargeable is 1.2v. For most applications thats fine but for some it isnt. Wii remotes are a good example - the charge state is monitored and once it dropps below a certain level they stop working. That level is just under 1.2v meaning that rechargeables cant be left to discharege - as soon as they loose their initial full 1.2v and drop to 1.1v (normal) they stop working.

it doesnt help that such uses are often those which rechargeables are perfect for in theory - ie high useage. If you use non rechargeables than you'd spend a small fortune (with my kids at least) - so its the lesser of two evils.

Im looking a the newer rechargeables that have 1.5v nominal - but they need special charges - so the charging docs (that keep the handets topped up) wont work - in fact could distroy the batteries. That means taking them out of the remotes and charging them seperately when needed - which the kids wont appreciate. Ultimately it means 16 batteries. 8 in the remotes and 8 spares. when they die - swop them and charge the dead ones.

Theres always a way, and theres always compromise. Whats best is completely up to the individual.

I think the suggestion about giving the "bad" batteries a quick blast with a cheap charger will solve the problem.

Here's my take on what happens from experience with my own "intelligent" charger.

When you use batteries in sets they don't all have exactly the same capacity even if they are nominally identical. The one with the least capacity may end up getting reverse charged a little before the device finally reports flat batteries. Such reverse charged batteries will show as "bad" on the charger. You can check this with a multimeter if you have one.

An alternative is to recharge the batteries before they are totally flat - that way there is less chance of one being reverse charged. This was bad practice with NiCad but doesn't seriously harm the newer NiMh types although it may slightly reduce their overall lifetime.
