| 417587 | 2006-01-03 03:16:00 | I have just unsoldered an old battery from a computer, as it was dead and starting to leak. it has written on it: Varta Ni/Cd 3/V60R 3.6v 60mAh 14h 6mA 122 Where can I get a replacement NiCd like that?? does it even have to be NiCd?? as far as I knew computers didn't charge the bios battery... |

| 417588 | 2006-01-03 03:37:00 | It's too late now, but it is much better to snip off a dead battery, to leave short stubs to which a replacement can be soldered. Re-chargeable nicads used to be used on older 386/486s, it could be difficult to find exactly the same ones now. Many boards though, also had a couple of pins in the vicinity of the rechargeable to which an "off-board" battery could be connected. Any old 3 volts will do, like a couple of AAAs, or a CR2032 mounted in a battery holder salvaged from an old motherboard, but dont connect to where the rechargeable was. |

| 417589 | 2006-01-03 03:44:00 | actually there is a pin header for a second battery.. although I managed to download the manual for the board here (support.octek.com.au), there was no information about the batteries. I take it that the removable battery would be a non-rechargable type? |

| 417590 | 2006-01-03 04:51:00 | I take it that the removable battery would be a non-rechargable type? That's right, I see that P15 is the connector for an external battery. These batteries in a case with a plug on a flying lead used to be available at exhorbitant prices, and they were usually stuck with Velcro to a convenient part of the case, but any 3 volts will do. Hopefully P15 will have polarity marked. |

| 417591 | 2006-01-04 00:46:00 | South Island Components (sicom.co.nz/) in Christcurch stock a NiMH replacement (BGP60K) for $4.29 + GST. The 4.5V lithium batterires which connect to that pin header cost about $40 these days. They are best replaced with a 2- or 3-cell AA cell holder and a few alkalines. You could solder the cells together, and even solder to the MB pins (taking great care with the polarity). Some IBM models used a Dallas clock/memory/battery module. Soldered in. :( |
