[SLUG] Question on lithium ion batteries.

2015-01-22 Thread William Bennett
So, having absorbed, from my friends,  the dangers of partially recharging
a  lithium-ion battery due to “memory”, I read the insert that came with
the new laptop battery:  –

“Recharging a partially charged lithium-ion does not cause harm because
there is no memory. Short battery life is mainly caused by heat rather than
charge/discharge patterns.”

Um, who's right?

No memory on Lithium batteries, that was an effect you would see on
Nickel-Cadmium batteries and in a more limited sense Nickel-Metal-Hydride.

Only issues with Lithium batteries is they like to be kept cool, and the
best long term storage charge amount is about 30%, not full.

Menno,

Thanks for the information.

I will add this: you'd be surprised how many computer experts,
professionals included,

labouring under this misapprehension.

I asked around because I had been told of the existence of “memory”, but
felt that the

manufacturers should know what they were talking about.
