They are excellent value. I bought a load of them last year and will be buying more.

Am I missing something here,but the 7 day ones seem to be more expensive.
Chargers look to be fairly competitive though.

The 7dayshop batteries are lithium.
Lidl are NiMH
NiMH like NiCad have a memory so you have to discharge fully each time

Sorry I was comparing like for like!
NiMh in my exp have no significant memory.

NiMH do have a memory effect, but not as bad as NiCAD.
Li are the only ones with no memory effect.
Still a bargin though

AS I get older I find that I have no memory effect as well. /forums/images/graemlins/smile.gif

Twelve Volt cigarette lighter plug supplied battery charger to take AAA, AA batteries. Came with four 2000MampH AA's of type NiMH - 40 euros. Been working regularly over two years.
Supplier in Las Palmas de Gran Canaria.
I do find various brands of MiMH AA's don;t seem to hold a charge for more than a week.

The shops supplying electronic tat to cruise ship passengers are poor quality, but the rest of the city and the Canaries and peninsular Spain is as good as Great Britain. Spain is not a virtual third world country, although perhaps Great Britain is looking that way.

Not actually
they are NiMH, but 2500 instead of 2100μah.
Don't know of any A, AA or AAA cells in lithium - perhaps U can point to some.
I've found the 2500 to be more fault prone than 2100μah as well as about 50% more costly.

Doesn't accept ASCII symbols - for the garbage above read milliamp hour.
Other disadvantage, you can't sit on your butt and get the Lidl, you've got to present yourself in person, and after 26th january - I've got better things to do with my time!!!

But are these lithiums rechargeable? The bumph doesn't indicate that they are.

modern nicads dont have memory problem.. it was decades ago, and the" myth" continues. Unless you have a fairly sophisticated fast charger though, discharging first means the charger is more likely to identify peak charge correctly. Or if you have a trickle charger, you are more likely to charge for the correct time. One advantage of nicads is that they hold the voltage at a more steady, higher level for longer before a fast drop off. Good for some applications.

As you say. Doesn't look as though they are rechargeable.

Re: Not actually
Tisme,
I found this information on http://www.greenbatteries.com/libafa.html#Li-ion%20in%20AAFAQ's. So I suppose that answers everyones question on rechargeable Lithium Ion batteries.
"Are Lithium Ion batteries available in standard sizes like AA , C or D cell size?
No, Lithium-ion batteries are not available in standard sizes. We believe this is because it would be too easy for users to inadvertently put them in a charger not designed for Lithium-ion batteries creating a potentially dangerous situation. (If an alkaline battery is put into the wrong charger it might leak or even burst, but a lithium-ion battery put into a NiCd or NiMH charger not designed for lithium-ion, might ignite. Also, because Li-ion batteries operate at much higher voltage (typically 3.7V per cell) than the 1.2 to 1.5V of most cell batteries, designing a 1.5V lithium-ion cell would be expensive."
