These may be a fraction of shop prices, but I suspect they may be fake. I use these in cycle lights and 'genuine' ones last me two winters.
I purchased these at the beginning of November 2010, and by the end of the month all are spent, each pair lasting between two days and two weeks. Not quite the same as two years!
im using the batteries for my bike lights, and in 2 weeks in need to replace them. i dont know if is thia what they last or is that they dont take well the moist of the air in the street, but with other brands this didnt happen...
12 batteries for our kitchen scales for £2.59 is great value for money.
Have only needed to use 2 of the batteries so far (thats how many our scales take), and they work fine. Im sure they will last quite a while before they need to be replaced.
Good value for money, considering how much these will cost on the high street - Boots will charge you £4.99 just for 2 of these...
