Thats guaranteed is it?

Good ..explosion my a
Remember to recycle your batteries.

These are Alkaline, not lithium. So no they won’t.
AAA same price
£9.34 now
AAA still ok to buy, AAs must have started selling out

or buy rechargeable!

An alkaline battery will drop to ~1.2-1.3v very quickly under even a modest load, a Ni-based battery will maintain 1.2v for most of the discharge.

For almost everything they’re interchangeable.

The problem with high capacity NiMH is the voltage sag in higher current devices.

Just so long as it does not destroy the planet.
Alkaline batteries are for things like remote controls and wall clocks that you want to last for a long time at low energy. If you use these in xbox controllers or cameras they will die after 5 minutes. You want NiMH or Li ion batteries for these things.

What do you class as low power ???? Under 100 watts ?

I wouldn't say NiMH, but definitely Liion.

Alkaline batteries are good for high drain stuff, been using them for ages.

33375338-KbI27.jpgthis is a discharge at 1C (2 amp) for the eneloop (an AA battery), vs 2 different 'D' size cells at the same discharge current.


And it shows the little NiMH stays above 1.2 V for longer than the massive (in comparison) D size batteries, despite the fact they're actually being discharged at significantly lower rates compared to their capacity than the rechargeable AA is. If the test was done between AA batteries the alkalines would look significantly worse as they just can't handle this kind of discharge current.

NiMH batteries excel at higher currents compared to alkaline batteries as their internal resistance is much lower. This is why alkaline batteries are awful in digital cameras and the like - the voltage sags are huge under load. Nickle chemistry batteries are much better. Lithium is better still, but you can't get a comparable rechargeable lithium battery and primary lithium cells are expensive and the higher voltages can damage equipment not designed for them, especially if multiples are used in series.
