Hi all
going to put away my set of mtb batteries xml light set
Do i need to drain the battery of juice before i retire it for a few months or so!!
If not what is the best longterm storage solution so that i do not bugger up the battery pack??
Many thanks
Martin
Funnily enough, was tempted to ask exactly this question myself...
Store them at 40% charge in a cool dry place

Best way with any Li-Ion battery is best stored just over 50% charged if left for long peroids.
Although the battery isnt being used, the protection circuit still monitors each cell - although this is only a few milliAmps this can build up if left in a relatively low state of charge. This will continue to drain the battery, even below its lower level cut off voltage limit.
Also Li-Ion batteries, do not like to be left for long periods 100% charged either and can effect the long term impedance of the battery.
Lastly, Not kept in a fridge either.. just somewhere cool, like a cupboard.
