Came across this video a few days back. It's a comparison between the cheap batteries and the expensive.
One aspect he discusses is cost per hour of a given brand of batteries. For some applications, cheaper is better. Others, the expensive are better.
He performs some simple tests to find out.
I only use rechargeable AA batteries.
What happens when the power go's off and they can't be recharged?
How long will they store with a full charge?
I have various rechargeable stuff and if they're not kept up on a charge. They discharge themselves in a progressive way of things. Being rechargeable is about the only thing I've seen them being good at.
...with uncalibrated, unreliable test equipment. How can he possibly know each cheap fan is going to pull power at the same rate? He can't. His test results are interesting and, I'm sure, somewhat valid. But they should come with a big pinch of salt.He performs some simple tests to find out.
Yes, that's why I stopped using Rayovac in anything that might be damaged. In my experience, they are the worst at leaking.One thing that doesn't get tested is the likelihood that it will leak. A dead battery is inconvenient, but one that leaks can destroy my equipment.
Or solar; we have solar charges for phones and solar power bricks for scanners and 2-way radios. The upside of rechargable is there is at least a chance to re-new the energy... Alkis once dead are just trash.get a jump start battery for your car and you can use it to charge the AA's or fire up the generator and recharge them while the fridge is cooling down.
