APPLE powerbook g4 battery Buying Guide

Here's What You Should Consider Before Purchasing a APPLE powerbook g4 battery:

Lithium APPLE powerbook g4 battery are interchangeable between any of the different processor speeds. An A1012 battery will work in a 500 MHz PB as well as a 1 GHz PB. The main difference between the model numbers is the battery's capacity.

Li-Ion batteries have a 300 to 500 cycle lifetime. Mac OS X Tiger (10.4.3 and on) allows you to monitor the number of cycles on a battery using the System Profiler. Try to avoid a used battery that has a very high number of cycles on it.

A new APPLE powerbook g4 battery should be able to play a DVD for about 2 and a half hours. A good used battery should be able to play a DVD for at least an hour and a half. A used battery that plays a DVD for about an hour and a half will probably operate for over 2 hours under "normal" operating conditions (this is just an educated guess based upon my experience).

Li-Ion batteries tend to lose about 15% capacity each year, depending upon storage conditions. Try to avoid purchasing a battery that is more than 5 years old.

Be cautious if you're considering a battery where the listing doesn't provide any test data. It's a simple matter to test the battery and provide operating conditions and run time in the listing.
Be cautious when a battery listing makes claims like "holds full charge" or "all 4 lights illuminate" . As I stated above, this means virtually nothing regarding the health of the battery.

APPLE PowerBook G4 Battery buying guide:

Li-Ion batteries combine the best qualities of alkaline batteries with the best qualities of rechargeable batteries. Li-ion batteries provide constant voltage during discharge and do not suffer from the memory effect that plague Ni-Cd batteries. Li-ion batteries also provide the highest available energy density of any available battery technology (i.e. provides more power per ounce as compared to NiMH or NiCad) Li-Ion batteries also have a low self-discharge rate (about 5% per month) compared to Nickel Metal Hydride (about 30% per month) or Ni-Cd (about 20% per month). A little known characteristic of Li-Ion battery technology is that Li-Ion batteries lose approximately 15% usable capacity each year (depends upon storage temperature). Because of their characteristics, PowerBook batteries can operate for between 300-500 cycles and last for about 5 years from the manufacture date.
