brken mb battery clip

IBM PC 300GL

Broken motherboard battery clip. Big problem.

I couldn't slide the battery out of it's holder sideways, so I lifted the
clip up too far & it snapped right at its base.

I've tried to hold it in contact position with some super/crazy glue and
electrical tape. Which kinda worked for a while, but not permanently. Now
after each shut down, the bios settings are lost & .I have to find a decent
solution without replacing the motherboard ($$).

I have just removed the entire motherboard to see how the battery holder is
attached, and how I might be able to tackle the problem.

Underneath the board there are two 'pins' soldered - one must lead from the
clip (positive) and the other from the contact below the battery (negative).

One option I considered was applying a little heat, with an electrical
soldering iron, to these two points to free the entire battery holder? Maybe
I can replace it.

Another option is to try & solder the clip back in position. Problem is
there is no stem protruding and I'd have to try & cut away a bit of the hard
black plastic surrounding the base of the clip that remains below the
surface. This would have to be done with the battery in position which has
an explosive risk attached, and also the risk of dropping a bit of solder on
the mb.

Another thought was to take a bit of electric wire, strip the insulation and
try to attach one end to the battery (tape or solder or glue) and try to
wedge and/or solder or glue the other end to the remaining clip stem.
Or attach the electrical wire to the battery and take it around to the
bottom of the board to the point where the positive terminal solder
point/pin from the clip is located? The battery holder is located near the
edge of the mb so I could get some wire around.

Has anyone had and solved this problem - let me know what you think my best
avenue is - I gotta get this machine up and running again.

I've heard of an epoxy type glue with metal content that is conductive ?

Just replace the battery holder... generally there are just two solder
points (+ and -).

You might find a suitable replacement on some dead mobos you might have
lying around...

I've only done an electric solder once before - plumbing is more what I'm
used to
The two solder points on the underside of the board - one looks like it
comes from the bottom of the battery and the other looks like it comes from
the broken retaining clip stem. These are what you refer to -right ? If I
apply heat to these they should loosen and allow the entire holder o come
out ? And then if I find a replacement, push the two pins through the board
and solder them on the underside ?

Hi fhg,

Just to relieve any issues that you have in doing this, it's not unlike
sweating copper pipes. I'm an industrial technician and done both

If you apply heat to the bottom of the posts, on the underside of the
motherboard, you should be fine. If you start to see any discoloration on
the motherboard, stop applying heat. Usually, these are manufactured with a
solder 'paste', but a soldering iron is used to repair them. Try to use a
fine tip on the iron, applied directly to the solder, and it should come out
without any issue. If you notice any type of smoke, don't worry too much,
that's usually just a small coating, or a flux that is applied after the
'reflow' of the solder has been done. Just watch the board for any
discoloration, to the organic material itself.

When reapplying, make sure and use a form of flux. Around the holes, you
should notice the 'solder pad' and try to use those as best as possible.
That is actually the run, or the electrical contact that the battery needs.
When done, look for any 'solder balls' (small spatter of solder from the
initial heating) and remove. These can cause a short on the system, which
will put you in deep doo doo. If needed, use a solder 'wick' (small, copper
strand, usually found at most electrical sellers, like radio hut) to remove
them. You just heat the wick and drag across the solder balls to remove.
To tie to sweating, try to use the flux to 'drag' the flux around the
connection and solder pads.

Just like plumbing, get yourself setup, good lighting, firm work area. Take
two deep breaths and have at it. Just remember, this is not silver solder,
so you don't need quite that much heat...

I've found identical battery clips in old car radios and even in old VCR's.
Like others have said if you're experienced in soldering/desoldering very
easy to change but if not you can ruin it.

Essentially, correct.. but be careful not to apply too much heat or you
will destroy the mobo...

Ghost

removing the old one sounds easy enough - heat the two points on the
underside and lift the holder up & out.
However, replacing a new one and soldering the points back to ensure the
contact with the mb circuitry (pad, run, balls, wick......... yikes !

Thanks to all for replies.

Do you think a 2 battery AAA or AA battery holder (Radio Shack) with pos.
wire attached (soldered if possible) to the broken off stem of the clip (I
can file away the black pastic and expose it a wee bit), and the other neg.
wire attached to the silver bit that was beneath the battery in the holder,
would do it?
If I could get away with AAA rather than AA it would save a little space.
Another option may be a cell phone battery with the plug cut off and the
wires attached

I feel a little unsure of replacing the original holder - heating the two
points on the mb underside and lifting the holder up and out sounds doable.
However getting a replacement attached correctly with the right contact to
the circuitry sounds more challenging.

in principle, is it a viable option to use one of these?
