521792 2007-02-02 02:56:00 I have some AAs which are not in use, they are kinda spares when I go out and shoot a lot. When they are not in use how do I store them? It could be months before they are used, some have not been charged even once in a yr's time.

Do I leave them in a dry cool area, do they go off by itself if not charged or used?

This is a trick question..right?

If you are shooting the batteries, it doesn't matter if they are charged or not.

Grrooaannn, Joe.

But seriously, I'd also like to know the answer to Nomad's question. I have rechargeables that rarely get used.

521796 2007-02-02 06:58:00 "Most" rechargeables self discharge a few % per day. If it was 2% per day, after 1 day from full charge they are at 98%, ofter 2 days 96.04, 3 days 94.11 etc (2% of what is remaining, not of the original).

So it matters little if they start off charged or not, they will soon be "uncharged". Store in an environmentally friendly place, warm and dry, but they will still self discharge.

The exceptions are the Sanyo "eneloop" AA ones now on the market that are supposed to maintain a good charge for a year.

Thanks GF. What happens if the batteries are not used in a yr or so, should a person charge them each 3 or 6 months just to prevent them not being operative? Like use the discharge/charge function. I read on the net that they say, you should not store unused batteries 6 months or you may find they may not charge at all ..

For others, it wasn't a trick question ..:o

521800 2007-02-02 09:31:00 What about Lithium-ion?
I've recently bought 2 for my 5 year old Archos MP3 player, the second as a spare just in case, eventually, the batteries become no longer available.
Should I keep both in use?

PS I understand that one problem with iPods is repairs and spares. There's a guy in the States who can supply just about every part you might need for an Archos and his service is awesome.

I know for lithiums they do not like it when you let them drain off. Lithium guys love it when they get charged while their stomach is semi full :D

When you leave the lithium overtime it will slowly discharge, could be the same or slower then the others not sure, but they will eventually.
