are these LR754 batteries?
Why are 8 2032 batteries £12.71 i.e. more than £1.50 each when 4 batteries are £3.27, so less than a £1 each. 10 Duracell 2032's are also only £7.20.

They do what batteries do - work a treat
Not much to say - they do the job well at a price that reflects their quality.

Backup
Bought as backup. Don't really use these size batteries much but never seem to have one when I need one. So bought these since they advertise the longest shelf life and of course are a recognised brand. To use an old saying 'it's better to have them and not need them than to need them but not have them'. Only knocking off a star because I haven't used them so really can't yet say how wonderful they are.
