These may be rubbish but the Kodak rechargeables (2 x AA for £1) are great.
these are zinc
This is the problem, they're are misleading consumers, because they are batteries for a very light use.
Well, to be fair, these are for light use. I use them for my wall clock, doorbell, even in a flashlight bike. If you get the right use the deal is superb! Stop say it's crap because you are use them in power hungry devices.
I can confirm these batteries are garbage. My daughters Ollie the Owl takes 4 at a time and they need replacing every 2 days with the same usage as I’d been getting 5 days out of my Energizer ones.
