That much is true, but it doesn't detract from the fact that trying to recharge dry cells is pointless given the variety of proper rechargeable cells that are available.

As to watch batteries, this is one of the few applications where it is more sensible to use non-rechargeables: where they last for a year or more. Here, the self-discharge of a rechargeable becomes significant.

Why is it that a lot of these posts dissolve into the 'green issue'. I get fed up having to wade through a post weeding out the bits about bargains (which this site is about) and some bloke demanding we stop buying/using something which will contribute massively to the saving of our planet.

It would be far simpler if a post consisted of price, location, any good, anywhere cheaper not 'if you dont fart for a week we may get snow at christmas'

I am not into the green hype but you seem to be listening to the battery companies hype.
If you are selling a product in the UK it has to pass a series of tests, If there was a chance of exploding batteries the item would be banned.

Maplins have a cheaper greener charger only £9.99

Sorry to OP for going off topic. But,


NO, I am a chartered electrical engineer and know what I am talking about.

The warnings are for safety reasons, not to con you.

Batteries ARE safe, WHEN being used for the purpose they were supplied for, hence ordinary carbon-zinc and alkaline types not recommended or really suitable to re-charge, hence the warnings. You would get just as much extra use as your recommended devices by heating you batteries too, again not recommended.

So you save 20p on a 30p battery by spending £15?, and still have to throw it away, your choice.;)

When being recharged ALL batteries emit gasses some of which can cause explosions, especially lead acid. Lithium batteries are highly explosive when mis-treated, yet still are sold with every computer.

Non-rechargeable should be used in preference to rechargeables for low drain uses - e.g clocks, remote controls. Rechargeables will run out more quickly in these situations, needing frequent re-charging, thus using more electricity.

Could it possibly be because buying rechargeable batteries is the bargain of the century compared with feeding power-hungry appliances with "bargain" packs of dry cells?

If you are an chartered electrical engineer you should have posted your second post first.
I thought the "frought with danger of explosion" might worry people who already have a charger/regenerator.

The chargers/regenerators for normal batteries on sale a few years ago had problems with overheating and were withdrawn. They have now been fixed/upgraded and they all have warnings on the packets (& optional gas mask):p

PS stop giving terrorists ideas "Lithium batteries are highly explosive when mis-treated":eek:

That's hardly news! Petrol is also highly explosive when mis-treated, and a good deal cheaper than lithium batteries...

10's of thousands of rechargable batteries are thrown away every year...........and they are 1000 times more damaging to the enviroment than ordinary zinc carbon batteries..........

Sorry, but are we not going a bit OFF TOPIC here ?

According to http://en.wikipedia.org/wiki/Rechargeable_batteries NiCd batteries can be recharged 1500 times so even if they are 1000 times more damaging than zinc carbon when thrown away they would appear to be better overall.

What do you mean by '1000 times more harmful'?
