Best charing method to protect battery health?

I was wondering what you guys think about this topic. I use my macbook quite a bit, usually at least have to charge it 1 to 1.5 times per day. What is the best method of charging to get the best batter health? I have heard some said to charge it before 30,35%, some said let it drop to "critical battery level" then recharge, etc. how do you guys go about it?

 

Usually, let the battery run down to say about 10-20% battery charge before charging up. I don't think there's a real optimal setting that always works, but let it go down, yes.

 

everything's Li-Ion these days so it shouldn't make a difference. i charge mine up if i'm near a wall, i don't if i'm not.

but i'd recommend doing a complete charge/discharge cycle at least once a month...

here's some infor:
Simple Guidelines

* Avoid frequent full discharges because this puts additional strain on the battery. Several partial discharges with frequent recharges are better for lithium-ion than one deep one. Recharging a partially charged lithium-ion does not cause harm because there is no memory. (In this respect, lithium-ion differs from nickel-based batteries.) Short battery life in a laptop is mainly cause by heat rather than charge / discharge patterns.

* Batteries with fuel gauge (laptops) should be calibrated by applying a deliberate full discharge once every 30 charges. Running the pack down in the equipment does this. If ignored, the fuel gauge will become increasingly less accurate and in some cases cut off the device prematurely.

* Keep the lithium-ion battery cool. Avoid a hot car. For prolonged storage, keep the battery at a 40% charge level.

* Consider removing the battery from a laptop when running on fixed power. (Some laptop manufacturers are concerned about dust and moisture accumulating inside the battery casing.)

* Avoid purchasing spare lithium-ion batteries for later use. Observe manufacturing dates. Do not buy old stock, even if sold at clearance prices.

* If you have a spare lithium-ion battery, use one to the fullest and keep the other cool by placing it in the refrigerator. Do not freeze the battery. For best results, store the battery at 40% state-of-charge.

Thanks all, very helpful!
