Which rechargeable batteries?

[Madders]

For an LED Lenser front light. Lots of unknown brands on ebay but thinking of 1000 maH high performance Uniross batteries. They are the AAA type btw. Any ideas?

I use these, 1100 maH, mainly for my electric (battery powered) toothbrush, usually last me over a week before I notice its slowing down and recharge them.

I believe Sanyo 'Eneloop' are considered to be very good, a little more expensive. I have not had a great deal of joy with Uniross and lots of other people have had problems. Had some ome of the Fuji ones, they seem okay.

Maplin batteries are good - worth buying when on offer. I tend to use hybrid batteries, slightly less run time, but much better standby. Maplin, EverReady, Panasonic Hybrids

2700 MAh Uniross performance.

Mine last me Oct to April on 3 or 4 charges. 2 hours a day - ride every week day.

Having said that, get the highest MAh available and any decent brand should be good enough

These....

Can't go wrong with Uniross.

The more capacity there is the less stable it is and the faster the capacity degrades.
So I wouldn't worry too much about capacity.

They'll be AA (I've got some 2900mAh from 7 day shop). OP needs AAA

Yes, they have to be AAA, pencil thickness. Smaller, I guess, means less capacity.

Sorry you're right. The AAA equivalent is 1000MAh.

I tend to go for either Vapex ( http://www.component-shop.co.uk/html/aaa.html ) or for Uniross.

I would recommend low self discharge (LSD) hybrid type batteries such as Sanyo Eneloop, Uniross Hybrio or GP Recyko (which are being sold off at PC World, so you could get some cheap if you're lucky). Though the capacity is slightly less, they hold their charge, and are far more tolerant of abuse. High capacity NiMH cells in particular are fragile and you'll find their capacity will soon drop off with repeated use. Worse still, you normally find one cell is weaker than the others with less capacity - in use that weak cell gets overdischarged and will suffer an early death. All the LSD batteries I've tested are closely matched in capacity, so this won't happen: they're much more reliable.

^^^^^^McWobble speaks the truth ^^^^^^^
Sanyo Eneloops are really good. I think that their AAA cells are "only" 800mAh, but the technology is far in advance of a lot of their rivals. Willy-waving "capacity" is a poor indicator of overall performance.
