Hi, You can rebuild the original battery without a lead-acid battery. I have rebuild one using 10x AA NimH batteries of 1.2 Volts, 2500 Mah ( 2x series of 5 ).
The main advantage is that it doesn't matter anymore if the Mac portable drains these batteries completely. You can easily recharge them without problems. They easily fit into the original battery housing: works perfect and capacity is the same as the original lead-acid battery.
