Please explain the difference between battery manufacturers

Hi everyone,

I would be very grateful if other posters imparted their opinion on the difference between battery manufacturers.

The specific details in my case are that I am looking to buy some CR2032 cells for my newly acquired electronics which require them (bike computer, scales, e-dictionary) and since they cost an arm and a leg on the high street I am looking to buy them on eBay, where they are cheaper and there is more choice.

I was astonished at the range of prices on eBay for CR2032 lithium cells. One can either pay £6-7 for 10 Duracell ones, £4 for 10 GP ones or roughly £2 for 10 power-stations ones. Can anyone explain this rather large difference in price?

Is it a matter of longevity? Is a GP cell (at twice the price of a power-stations cell) last twice as long, etc? Or would I be paying for the manufacturer's name on the packaging?

I'm interested first and foremost in value for money. I suspect that if I go for the cheapest batteries I probably won't have to replace them twice as often so they will probably be better value for money, but are they more likely to leak? How likely is it even for a lithium CR2032 cell to leak and harm the equipment?

I would greatly appreciate any replies,

Many thanks,

Vladimir.
