Rechargable Batteries Lidl

I got a 4-pack a while back (greyish exterior), and they are a little wider than normal and they also don't hold their charge nearly as well as a smaller 1800mAh one I have. I thought these would last longer due to the rating, but they don't.

That would depend on what you are using to charge them. To get the maximum life out of rechargeables, a good voltage sense charger is required. If your charging higher capacity batteries in a charger designed to charge lower capacity batteries e.g. timer type charger, they will never reach their full capacity.

I agree that the Lidl ones are very good value and work just fine.

Surely you just have to leave them in the charger longer.

Time to charge 1800maH, x 25/18, i.e. almost half as long again to recharge the 2500maH ones.

Note batteries tend to get hot when they are fully charged

Depends on the charger, some will say that they are charged but charging stops due to a timer.

Agreed a higher capacity battery will take longer to fully charge using the same charger.

A good charger e.g. here will sense that they are fully charged and stop the charging current, so they should not get hot when done!

It was exactly that charger that exploded my Lidl batteries. I had red hot bits of black goo bubbling away all round the bedroom. I started up a case with trading standards but unfortunately my wife through the exploded battery away!

I think that you were just unlucky with a faulty battery. I have used that charger and Lidl/Aldi batteries for several years with no problems.

I bought Lidl's 12 x AA size batteries for my digital camera and found them to be terrible... the shortest life by far when compared to Duracell and Energiser brands.

Maybe I got a bad batch, but I haven't bought any since....

I would guess that it was the charger that was faulty, not the batteries.

You can charge batteries indefinitely if the charging current is limited to one tenth of the battery capacity.
Fast chargers are usually the cause of poor battery life.

This thread is about rechargeable batteries.

:rolleyes:

They would be ordinary zinc chloride batteries if in a pack of 12 and thus false economy. You need heavy duty batteries for cameras, preferably rechargeable, Alkaline are useable but more expensive as what you spend is dead money. Alkaline are best kept as backup for if your batteries run out when you have no access to a charger.

I use a "smart" charger, not a timer one.
