Default NiMh batteries in Lidl

These have previously been mentioned as good so today 20 Dec 16 I bought some of their AAA batteries 8 for £4.99. Also have AA at same price. Only available until stock runs out as usual.
No connection, just passing on info.

I bought some of the AAs yesterday again for £4.99. There were still plenty left of both types. They seem to have a Christmasy plastic coat.

I also bought a set today. They have reasonable capacity (though nothing special) and low self discharge. They seem good value, though the cell colouring does make them look tacky.

It's always worth looking at the capacity such cells claim: I've seen plenty that are cheap but are rather questionable in terms of milliamp-hour rating.

Of course not everything *needs* maximum capacity so there can be situations where cheaper but lower capacity are a good option. Horses for courses.

These claim 2300mA, which is pretty average though far from class leading. The Poundland ones are 800mA, which is very feeble but OK for the price if you understand what you're buying and don't need the capacity.

Yes I started this thread https://www.vintage-radio.net/forum/...d.php?t=121819 in December last year and I've had no problems with the ones I bought then though they haven't been subjected to particularly intensive use.

Hi

I've bought several rechargeable NiMH cells from Lidl over the years and have been generally very pleased with them.

I did however have a problem with a batch purchased a few years ago. These appeared to be short circuit possibly due to tin dendrites though I can't be sure. To be fair, these were inadvertently neglected and thus not correctly charged as they should have been so that's probably the reason for failure. I did try to "blast" the s/c cells with a large value charged electrolytic capacitor without success so had to reluctantly concede and disposed of these "new" cells at the recycling centre.

Regards
Symon.

Weren't Eneloops the first low self discharge NiMHs?

This image from Wikipedia looks remarkably like the Lidl batteries in terms of physical appearance: https://en.wikipedia.org/wiki/File:E...pack_front.jpg Presumably the similarity is just a coincidence.

Yes they were. Also persistently the most reliable batteries I think I've ever had. I've had the oldest set about 6 years in monthly charge and discharge cycles in an HP 50G calculator and I can't see any capacity reduction yet.

Assume Lidl are trying to make their products look quality.

This site may be useful if looking for comparisons. http://www.batteryshowdown.com/
They do not appeaqr to have any bias, or commercial interest in any particular maker.
The testing is reasonably scientific.
Unexpectedly Ikea batteries seem way out in front, at least on cost per watt-hour ! Tony

I had an Eneloop go O/C for no apparent reason. It was only a couple of years old too. But I guess this could happen to any make of cell.

This would match my experience of them and my 'unconscious' purchase of dozens of them every time visit there (which isn't that often hence the large quantities).

I say 'unconscious' as you get a very distinct impression of battery efficiency during use and my previous 'favourite' was Duracell but the Ikea batteries seem to surpass even those - and with the low price benefit you can't go wrong.

The need to constantly (or so it seems) recharge batteries even when they aren't used is off-putting to me.

I've found IKEA and Amazon's own brand NIMH AAs to be very good at having a low self discharge rate and appearing to hold close to the capacity they're rated at. Both a lot cheaper than Eneloop branded ones too.

The low self discharge technology seems to have become pretty universal now. You can use them like alkalines in occasional use devices, just giving them a top up charge every year or so.

They also seem to survive well when exposed to wide temperature-changes; I've got a set of these in the 'outdoor' part of my weather-station and the current set have gone for six months without signalling 'low battery' back to the indoor-box - that's as good as any alkaline AA's. They're currently "basking" in a balmy -3.7 Centigrade environment.
