PowerBook G4 battery replacement recommendations

Hi, mph. There are lots of third-party replacement batteries on the market at a wide range of prices, as you've discovered. The least expensive battery I've seen widely advertised with a one-year warranty is this one bearing the TechFuel brand:

Many other vendors also sell it, perhaps at lower prices. I've seen no reports on it, positive or negative, from people who bought it.

I have, on the other hand, seen dozens of reports posted in these forums from disgusted buyers of $40-$75 batteries through Ebay, some of them "Apple-branded," that proved to be worthless, counterfeit junk. Stay away from those.

My personal inclination will always be to buy batteries from vendors that I trust to stand behind them if I have a problem. In my case, those vendors are smalldog.com and macsales.com. They don't have the lowest prices, but they are honest and dependable, and they don't sell junk.

When I replaced the battery in several Powerbooks, I've gone with one from OWC: http://eshop.macsales.com/shop/powerbook/battery/g4-12inch-aluminum/ . While not a great deal less expensive than the Apple battery, it's of good quality, and all have been performing well. Agree with eww that you get what you pay for.
