    Hello,

    I have searched but not found a good source of advice on general least impact use of batteries AA/AAA etc. We try to avoid but so many things use them.

    We use some rechargeable NiMh ones but they loose charge over time. We have a good charger that refreshes them.
    Are there any that hold charge better these days ? They were no good on remotes etc. all old batteries now.

    With Alkaline batteries - we take them or turn one around when not in use on things like torches to preserve them and they last well. We have them in remotes, computer mice etc. We recycle them but it would seem better to not keep buying them.

    I have come across some usb cable rechargable lithium batteries at £4 to £5 each with high capacity and you charge then off a USB lead. Has anyone used them? They would quickly pay for themselves in say 20 charges. eg amazon "USB AAA Lithium ion Rechargeable Battery, High Capacity 1.5V 550mWh Rechargeable AAA Battery, 1 H Fast Charge, 1200 Cycle with Type C Port Cable, Constant Output"

    I generally use nimh Eneloop AA and AAA, I'm happy with them - it's a nuisance having different brands/capacities, as you should try and match them up when you use them - and most self discharge annoyingly.
    Have also got some of the below in smoke alarms, they seem fine in place of the usual alkaline ones. I tried a NimH PP3, but it really didn't last long enough and was disappointing.

    Thanks Rob. I concluded modern nimh are much better at holding charge than my old ones. I have bought some nimh claiming 80% charge after 2 years and 1000 cycles.
    About a third of price if lithium ones but slower to charge.
    Lithium are 1.5 v rather than 1.2 v though.

    Been using Uniross rechargeables for years. No problems with them discharging too quickly

    I have 10-year lithium batteries in my smoke/heat alarms. They seem to be working so far. Dunno what my Casio watch has but it lasts ten years too. I replaced the batteries in our Dect phones with some Eneloop, but I'm not convinced they're working very well. They sometimes seem to discharge very quickly. In remotes I still use Lidl Aerocell AAA since they seem to last a long time.
