Fast dispatch and delivery. These 123 batteries are honest rechargeables, forget eBay's dishonest dealers quoting unrealistic capacities for these batteries, these are probably the best 123's available in UK.

Great technical advice and using these batteries has overcome my concern with wanting to use the 18350's which seem to need far too much supervision! They do stop working very abruptly, no slow run down, so have a spare available.

Does exactly what it says on the box, good battery from a reliable source.

Very good quality, no issues and they have replaced the duracells I ve been buying due to expensive cost and not being easily obtainable.

i bought the RCR 123A batteries to go in my range finding binoculars.

I bought four of these batteries. Two of them were right on 650mAh (648 and 652mAh, averaged on five charges each). One of them averaged 599 mAh and the last one had both a bit higher internal resistance than the others, and averaged only 572mAh. All batteries were charged at the recommended 300mA. However a reasonable price and fast delivery, even to Sweden.
