[RESOLVED] External battery for 486 boars

[Ron]

Does anyone know if you can still get "external batteries" (3.6v.) to salvage an old 486 mobo? Have searched, but can't seem to come up with a supply.

The logical answer would be "why would you want to", but some customers are sentimental I guess.

Thanks

The customers are not sentimental their cheap. Yes you can still get them. Look for a company called Federal Distributers.

Hi!
answer to your question is yes, they are still available.
We have a really great distributor for batteries among other misc things... They were formerly "Fedco", now called "3klix" here is their web address: http://www.3klix.com
also another to try is www.batterytech.com.
these are both wholesale distributors. batterytech will custom make any battery you need - they're awesome

Radio Shack carries them but you will have to order it. Only takes a couple of days and its not the cheapest place to by anything.

teh real question is can they afford it. I have done the proces 3 time and it takes about an hour. I cant justify spending that much on a 486!

There are several. You can get 3.6v and 4.5v from any number of places. Radio Shack, Frys, CompUSA, etc. Anywhere tho, you need to find someojne willing to look it up. Most stores don't keep them in stock.

They also make 6v ones. Most systems don't care if it is 6v or 3.6v as long as there is power. I even saw a 7.2v once. tho I feel that is pushing it.

how about the Dallas Real time clock. Its socketed so I pulled it out but it is dead but the battery is on the inside.

Anyone have a pinout of this thing? Itsa for a Pentium 133. I cant seem to find one anywhere. If I knew which terminals provide the voltage perhaps I could attach an external battery to it.

There is a good white paper at the above URL w/ some mention of the Dallas Clock.

As jhutto stated, voltage, up to about 6v, is immaterial. What I do is use one of the battery holders from Radio Shack (4 AA cells), solder the old connector on, and install 4 alkaline AA cells (6v total). Use small Velcro patches to hold in place. Quick and cheap. Takes about 20 min and alkaline cells will last a long time.

[oldman]

have you every seen what is left of the mainboard when those alkaline batteries leak

[Grafman]

There are drawbacks to any type of makeshift repairs, and I'm not talking about a lifetime warranty here. The solution to the leakage problem is to mount the pack in a location where the leakage will not get on the board. Hell, put 'em in a baggie. Also, I recommend not using batteries from the local salvage store. Good quality batteries do not, as a rule, leak until they are long dead.
