Just a quick surprisingly positive review of some NiMH cells. I finally replaced some ultramax AAAs from poundland, not very high capacity but they must have done about 4000+ charge cycles on 1 - 2hr charge rate. Quite impressive. Still working, but now taking excess charge time & discharging a fair bit overnight.

At least 11 years old even if charged every single day, so I doubt if
the same type are available to buy now, therefore they've served you
well, but the information is not particularly useful for anyone looking
to buy some rechargeables?

I think I detect another "diki-wiki" entry coming soon ;)

So go write the wiki yourself.

More like 5 years.
In a Poundish-type shop there were some LSD NiMH cells, but the AA were
about 800mAh and the AAA were about 300mAh, so obviously made to a price and
useless.
Aldidl's offerings seem to be good.

4000 / 365 = 10.9 years, use your own value for "+". If I had an
application that required such frequent** charging I'd be using the best
batteries I could find, not cheapos from Poundland.

Pretty much.

Yep, I bought a couple of packs first time I noticed them selling LSD
NiMH and then bought a boatload the next time they had them, enough to
pension-off all my non-LSD ones.




** Not that the O/P said they were being charged daily, but if they were
only being charged weekly they'd have lasted 76 years, which I somehow
doubt.

Ouch! - why was I 'thinking' in hours?

Yes - Eneloops as first choice for e,g, a camera.

Same here, along with the charger. Seems that the cells spec. a charging
time of 7h (AAA) at 190mA and the charger sold alongside boasts of its
speed! I've not seen a charger under about 30 quid that could be set to meet
that spec.

er, yes.

Meh, I wasnt thinking right there. About 1.5 years at 3-4 charge cycles a day is about 1900 cycles. Theyre still on sale in poundland.

/massive backpedal

So, old boy, what application is this that needs rechargeable batteries recharging 3-4 times a day for ~2 years??

Shurely a wall wart type power supply might be a better option?

Or how about simply bigger batteries?

Do they actually get full cycles, or just topups?
