Batteries in your fridge

Hi,

Pile alcaline is french for alkaline battery.

Take care,

Michel

I'm not sure if this is bullshit or not, but I was once told that charging a NiCad while keeping it cold, is supposed to help it charge better. He then said that the battery will perform better at normal temperatures.

No it's not bullshit. In fact, it is true of all chemical batteries. It is a widely known, and well established principle, that a cold battery accepts (gains) electron charge more readily than a warm battery. The reverse principle is also true: a warm battery delivers (loses) electron charge more readily than a cold battery.

Anybody who lives in a cool climate, and has owned a car long enough for the battery to start losing it's capacity, will likely to have experienced this principle first hand. That common problem of not being able to start the car first thing in the cold morning, and then "magically", a couple of hours and rising temperature degrees later,....Walaaaah! - it starts!

Cheers

Thanks for varifying that Bud

A french battery?

I also found it's bigger brother, a 1.25 volt D cell NiCd - I was wondering what type of current had to flow through one to recharge it?

Bossman, it says on it.

Does someone have a link to the charging characteristics of the modern rechargeable batteries?

Additionally,  I find it odd that, after browsing, that no one uses those C-cell sized rechargeable batteries from the RC car electric motor industry ( and everyone seems to have an oscilloscope and a function generator )
