Just received a new Lithium Ion laptop battery for my Dell laptop.
To cut a long story short order was duplicated so i now have two batteries and Dell have said keep it.

My question is is it better to keep one in the cupboard as a spare for a couple of years ,does its life start ticking away?, or is it better to use both batteries alternatively changing every week .

Thanks in advance Dominic

Leaving one as a spare for a couple of years shouldn't be a problem, but it may be worth giving it a charge every six months or so.

If they go completely flat they can be a pain to get going again. I've got an old Dell which I hadn't used for a few years and it took several hours before the batteries started to charge normally. I'm guessing the charger was very, very 'gentle' until it got some power in to them.

Battery life is reduced for each charge/discharge. It's peferable to keep one as a spare after ensuring a full charge, then replacing at annual intervals say, but dependent on the battery useage, (leaving a laptop continually plugged into the mains, will have a minimum effect on the life of the battery).

One manufacturer I remember recommended keeping a new battery in the fridge until required, (not freezer!)

Things last longer if you keep them in vinegar!

Except chips, ironically enough !!

Nowt worse than soggy chips

from memory, aren't LioN batteries optimised at about 18C, should be stored with about a half charge and topped up and discharged to about 50% every 3 - 4 months and shouldn't be stored when fully flat.

my laptop battery is only put into laptop when taking the laptop somewhere i know there will be no 240v for charger. the rest of the time laptop battery sits in office drawer.

When i do use laptop battery i still can get maybe 3/4 hours on battery
