Not low self discharge. Which is important for most things AAAs go in. Nice attempt at patronising the OP though.

This is my first ever comment on HotUKDeals so please be gentle!

I believe that with NiMH batteries likes these, you won't achieve full capacity until the battery has been through a few charge-discharge cycles according to batterystuff.com/kb/…tml so this may explain the lower capacity you measured (although I'm surprised it's as low as 367 mAh). Also the capacity of a battery depends on the rate of discharge according to some datasheets I have looked at in the past.

7dayshop claim that these are low self-discharge batteries and advertise them as retaining of 80% charge after one year of not being used although I have not checked this myself.

Another good reference is batteryuniversity.com/

Not the same product, so them having a slightly higher capacity doesn't necessarily make them a better buy-it'll depend on your needs. Personally I now always try and go for the low discharge ones.
I've had a number of rechargeable AA and AAA batteries from 7 day shop over the years. Unfortunately they rarely last long, and I'd suggest buying better brands such as Eneloop. There is a good reason why these are cheap. However, the price is good, so won't vote cold.

yes from totally flat
Try the IKEA rechargeables for about a fver for pack of 4 AA AAA.
Get the IKEA LADDAs instead (if you live near a store).

AAA
ikea.com/gb/…80/

AA
ikea.com/gb/…76/

They are Eneloops.
Edited by: "redserpent" 22nd Sep
Yup I love the Ikea laddas - took advice on here along with buying the xstar charger above ... awesome combo and first time I’ve ever been happy with my recharging setup
also recommend Varta recharagebles from Screwfix when on offer - sometimes down to £3.50/£4 for 4 AAA/AA
Voted hot for the price, but calling extra high capacity at 850mah it's a bit of a push.
PSP9122/09/2019 12:23

yes from totally flat


How did you confirm they were totally flat? When a device stops working because the batteries are "flat", that does not mean the batteries are totally out of charge. Most devices will stop functioning once the voltage drops below 0.9V, 0.8V or something like that.

It seems most likely that you have measured how much charge has been put in to batteries that aren't completely flat.

Get the fast charge Duracell one, about £15. Ignore comments that fast chargers kill batteries, have one since about 5 years ago, used on regular basis and didn't notice any changes in my batteries, 15 min and job done. If you're not keen on fast charge, there are plenty of chargers, some on 7days shop too, but will take much longer to charge.
The 1100mAh batteries from 7 day shop are imo the best value for money,I have tried just about every make in recent years and they lasted longest on my wireless headphones.Did you remember to charge the ones on the mAh meter PSP91?
Only 50p more for 1100mAh

Yeah but things that need a really low discharge (like remotes, clocks etc) are not really suitable for rechargeable batteries anyway. At least in economic terms.

Even cheap batteries like these are 12 for £7, whereas cheap zinc batteries for remotes etc can be commonly found for 12 for £1. So in order to make your money back, you'd have to use the AAAs 7 times. In low powered devices like remotes and clocks, that would likely take 10 years plus. Add in batteries breaking, being lost, etc and it's not worth it.

Of course, if you're buying for environmental reasons instead of economical, then it's a lot more difficult to work out how many times you have to use rechargeables to make it worthwhile.

Thanks, I posted that out too, but was told that I was patronising, even though I was just trying to help out and trying to give credit to the OP, if it wasn't for the OP I wouldn't have found it.

Again thanks to the OP .

They will last the longest if u are using the device within a couple of weeks its 1100mah not 850mah, but in remote controllers etc they probably won't last as long as a 850mah as over time the power will drain much faster when not in use. Like another said it will depend in which circumstances u are using the batteries.

Thanks that's really helpful 🙌
I have some of these and have found the capacity to be genuine based on my C9000 charger. IMO they self-discharge a fair bit faster than Eneloops though, but got nothing scientific on that.

IKEA ones are superb. Well worth the investment if you have a nearby store. Last for ages.
