Simple Guidelines--Great Battery
Written by GG from Cambridge
Feb 26, 2006
* 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.

Need another Battery

First battery lasted 18 months.......... Now it only holds charge for 30 mins or so.
I think $129 is a bit expensive if they are only going to last this sort of time, that's over $7 per month for a battery?
Shop around is my advice.......they can be purchased for less.
I do think Apple should be looking to supply better quality batteries at a more reasonable price too.
So come on Apple................look out for your customers! …More526 of 776 people found this useful

Fast discharge
Written by KP from Arlington

I've had an iBook since 2001. I use it mostly with the power cord rather than the battery. I've noticed recently that when I charge it fully and run it on the battery, after about an hour it dies even though the power meter registers over 50% charge. Has anyone else experienced this false charge reading? …More

Replacement back-up battery for the iBook G4. 15 minutes until it's dead. Overpriced and poor performer.

Fine at first. Then a couple of weeks go by and you lose half of the time. A few months and it's toast. Overpriced, poor product. I recommend an external battery. …More
