There's a £1 discount (promotion) if you buy 2 packs of '7dayshop "GOOD TO GO" AAA Pre Charged NiMh Rechargeable Batteries 850mAh 4 Pack' (other items are in this promotion too, e.g. 40 AA Alkaline batteries for £7.69).

1 pack is £2.79 delivered (£69.8p per battery, which isn't bad)
2 packs are (2 x £2.79) - £1 = £4.58 delivered (57.3p per battery)

Their low self-discharge makes them good for long use scenarios, where you don't want to change the batteries too often. If you plan to use enough AAAs in your devices over Christmas, then 8 batteries might be a good quantity for you.

Which? magazine gave the AA version of these batteries a good review in May 2014.

"These 850mAh AAA Cell batteries are pre-charged & are 'GOOD TO GO' straight out of the pack.
LSD batteries (Low self discharge) retain 85% of their capacity after one year, compared to about half for normal NiMH batteries.
7dayshop rechargeable batteries are compatible and will re-charge with any good quality Ni-Mh battery charger.
AAA size batteries are also known as LR3, LR03 and MN2400."

Thanks, good reviews too. You can never have enough batteries, SOLD!!

I' ve had several packs of AA and AAA rechargeables from 7dayshop both old style NiMh and good to go versions. None of them last more than a few charges. The good to go type didn't even last 6 months after I found a pack of 4 in a drawer I'd put them in, had lost the charge on 2, and the other 2 came up faulty on a top up recharging, using 7dayshops own intelligent charger. I'll not buy any more.

Completely agree! Worst rechargeable batteries ever. The ones I use for the xmas lights don't even last a full day - they started out with a week's charge! The ones on the photos are just so dull after just 3 recharges.

heat for posting a deal OP!

But Cannot recommend them at all!

Flamedeer thanks

Over the years I have had many rechargeable batteries from various manufacturers and have found that 'smart' chargers are not at all that smart. Often if a battery goes really flat having not been charged for a long time smart chargers refuse to charge them. I keep an old fashioned dumb charger just for that purpose, putting very flat batteries in it to charge over night works a treat.

good price...ordered

I bought a 7dayshop smart charger from a deal on here a couple of months agoand it was only putting 1.2v into them. I thought it would be an improvement on my 5 year old Aldi charger. I emailed them and they gave me a refund and didn't want it back. I'm back with the Aldi one which charges them properly even when completely flat. I've got various AA's, AAA's, C's D's including Sanyo eneloop, Panasonic eneloop, Fujicel, Amazon basics, 7dayshop, uniross. The only ones I have had problems with are Ansmann 1800mAh (2200mAh are ok)
Check your duff batteries in a non-smart charger you may find you can revive them.

Perfect, I've been looking for some extra strong mints for ages... oh, wait.

Thanks OP

NiMh batteries have a voltage of 1.2V; this is limited by the chemical reaction, Wikipedia says: "The voltage developed across a cell's terminals depends on the energy release of the chemical reactions of its electrodes and electrolyte".

The voltage of a charger has to be higher than that of the battery in order to charge it.

To me it seemed the complaint was that the battery voltage didn't increase beyond 1.2V? Just above 1.2V would be what you'd want from the charger to slow-charge a 1.2V battery?

Yes I expect to put at least 1.3v in the batteries to perform optimally. The sevendayshop charger was rejecting perfectly good batteries and sometimes only charging them to 1.17, 1.18. I thought the display was wrong to start off with but when my son came to me with a flat xbox1 controller for me to change the batteries and then returned 10 minutes later because they were flat again I realised it was the charger and not the batteries that was at fault.

Hmm, price increased to £4.98 for two packs.
