I have a replacement Li-ion battery. When should I start using it?

Hello!

I have a VAIO laptop, and we were given a replacement battery. The laptop is about a year old already, and so is the original battery. But the original battery is still working, and that's why I'm still using it.

However, I read that Li-ion batteries start degrading right after manufacture, and I'm worried that if I don't use the replacement battery soon, it might be too degraded to use.

When should I start using the replacement battery? Should I use the original and the replacement battery alternately?

I plan to keep this laptop for a long time, so I want to maximize the lifespans of both batteries. Thank you very much!
 
Just use both batteries, put one in the laptop and charge it, then charge the other one. Then when your on battery power and one dies, just swap in the other fully charged battery;)

Thank you! The truth is, I don't use my battery too often, because I often use my laptop as a desktop replacement (I remove the battery and plug it to AC). That way, I don't damage my battery too much. (At least that's how I think it is.)

A question though. If I DON'T use the replacement battery, how long do I expect it (the replacement battery) to last? Thanks.

Well, you shouldnt really just leave the battery in the laptop then. You should charge cycle your batteries every few weeks(full charge, then run them down to about 20%, charge back up) or else the cells will become "dead".
 
put the new battery in a ziplock bag, push out the air, and freeze it. that should hold the charge longer till you decide to use it. haven't tried this but i read it off some website long ago
