Keep spare batteries in the fridge?

I came across this site How to prolong lithium-based batteries while looking at ways of extending the life of Li Ion batteries and it reccommends storing your spare batteries partially charged at fridge temperatures to prolong their life.

If possible, store the battery in a cool place at about a 40% state-of-charge. Some reserve charge is needed to keep the battery and its protection circuit operational during prolonged storage. Avoid keeping the battery at full charge and high temperature.

Anyone got any comments on this?

I've heard of it before. It slows the chemical reaction and prolongs the life. be sure to insulate the battery, get some silica gel packs (common in packaging materials) and put it in a zip lock bag with the battery to keep moisture out. It may sound silly, but it's true. Also works for alkaline batteries.

The good life span of the average 901 battery is roughly a month or 2 it shouldn't make much difference but if ya keep the e-liquid in there anyway, why not

Thats for the link! I love graphs...
I especially liked the graph which show discharging your lithium ion battery lessens life. More ammo for putting your batteries on the charger whenever your not vaporizing. I never let my batteries die.

Is it OK to leave the battery on charge all the time, so it's fully charged the next time swap? Thanks.

Yes once your light goes green it indicates your battery has reached its charge capacity and charging is no longer taking place Keeping the battery in there is OK but you can turn the charger off to prolong its life!
