This is a bad idea on desktops, the real 3.6v lithium lasts ~7 years and only costs a few dollars off eBay or other online sources, no more cost than this wrong camera battery. This is the “G-Books” lists, he’s asking about laptop PRAM batteries which are usually 3 to 6 button cells that are welded together, shrink wrapped, and have a wire with a small motherboard connector attached. These cost $20-30 each, when the button cells can be bought online for less than $1 for all. The problem is constructing a replacement that will fit is very difficult from naked OEM button cells. You can buy the same individual cells with welded tabs on them already, then the problem is simplified to connecting the tabs to create the replacement, and attaching the wiring, then shrink wrapping the unit. This isn’t easy, but it may be doable. The tabbed cells will cost about $4-5, you can use the old wiring from the dead battery, and you’d need shrink wrap or good electrical tape. It may be easiest to find a different battery for a different electronic device that’s constructed from similar button cells with similar size & voltage to the Mac PRAM battery, but with different wire connector, and then cut the wires and splice on the Mac PRAM connector. Other batteries are sometimes half the price, say maybe $10 or so, but finding one that’s the correct voltage that will fit may be harder than assembling a replacement from the pre-welded, tabbed cells. -- -- You received this message because you are a member of G-Books, a group for those using G3 iBooks and PowerBooks (we run a separate list for G4 'Books).
