Lithium ion Rechargeable batteries tests ( AA, battery packs etc)

[Jim_e_Jib]

Are the company testing all of the batteries before each is accepted for use in a product or are they just checking samples from a batch to ensure general quality?

The number of charge/discharge cycles before capacity drops below a certain percentage might be useful as could the self discharge rate.

I imagine an AA battery has a specific size with an allowable tolerance. Does this need to be checked?

Likewise weight if the overall weight of your product is critical.

Jim_e_jib - thanks for your Inputs. They are only checking samples from a batch to ensure quality.
"The number of charge/discharge cycles before capacity drops below a certain percentage might be useful as could the self discharge rate." - yes definitely. Is this also referred to as an ageing test?

Also any idea what a sensitivity check is and also frequency response range check when testing rechargeable batteries?
Thanks.

Hi, that probably is what is meant by an aging test, although whether there is also some element of physical aging that can be tested too. I guess that's tricky to assess if it's in real time.

Self discharge is how quickly a battery looses it's charge when it is sat on a shelf unused.

I've no idea on the sensitivity or frequency response check I'm afraid.

Is your product likely to be used in extremes of temperature? Could be worth getting charge and discharge rates at the expected temperatures to make sure they meet the spec you need.
