Wow. I'm guilty of doing #3, now I know I shouldn't keep doing that. Thanks, wonderful input!

What kills the battery is high temperature, high number of cycles when doing 100-90-100-90-100 and keeping the battery at high level of charge (not just 100%) which is the same as keeping it at hot place.

Best is to get the battery to 40% charge and store it in fridge.

Yes, you are guilty of prolonging your battery's life!

Thanks mate. That remind me to add another point about how to store battery for longer period,

Great post! I always thought it's better to fully discharge, before recharging

Thanks for this. For years I've been very disciplined in ensuring the batteries of my electronics are fully discharged before I charge them. It's a bit sad to know my effort may have actually been wasted.

for everyone more interested in numbers and graphs take a look at this: http://batteryuniversity.com/learn/a...ased_batteries Table 3: Permanent capacity loss of lithium‑ion as a function of temperature and charge level.

np. btw you should warn people not to let totally empty batteries sit for prolonged times without use as they drop voltage over time without usage and their electronic circuitry _might_ prevent them from charging from deep discharge completely.

Thanks so much for the tips guys. I have always wanted to ask a expert in battery engineer about all the myths on internet about batteries.

I just hate I didn't recap the link I've posted before in this thread as did Xenova, so I would have 250+ "thanks" too. More and more this "thanks system" looks useless to me.
