Is it OK for me to recharge my A2's battery when it is down to one or two bars on the indicator, or should I completely exhaust the battery before recharging? If I recharge the battery when it is only half used up will it shorten my battery life? :confused:

I'm not exactly a specialist but I think for any battery it is always better to drain it completely before charging it again.

I know that this is critically important for the first few charges as you need to cycle the battery.

However, if I remember correctly the A2's battery does not show a memory effect,
so I think that after you have cycled the battery a few times you should be able to recharge it whenever you want without adverse effects.

Can anyone with more knowledge confirm this, or am I stating plain B.S. here?

Actually Li-ion batteries don't have memory effect so you can charge at any point without losing max capacity.
The problem is that as any other battery there is a limited life based on how many time you recharge the battery, so the few time you recharge the long battery life you get. (in my opinion)

Excellent link, eXity!
Thanks for sharing!

To all users: ignore my first post above, I was wrong. Sorry about that!

So in fact, you SHOULD actually frequently recharge your A2, it's better to recharge it a bit all the time than to let the battery drain completely.
(since it's a Li-ion polymer battery)

Are these 2 opinions true for (Li-ion) battery?

Hi,
from the website posted above it seems I was wrong.
A Li-Ion battery to make it have a longer life should be charged more often and usually it's better before it is empty.

Should the battery still be "cycled a few times" for the first time?
