Battery contact description

[quelgeek]

I have a ciruit board into which two AA cells are intended to be inserted in a spring-loaded carrier. The cells make contact with the board using a couple of "studs" that extend slightly beyond the edge of the board. What would you call a contact of this type if you were trying to google it? Here are top and bottom views:

pcb battery contact?

Hello,

Those contacts look quite corroded.
I would also check the continuety of the contact to the PCB track.
It can well be that the corrosion attacked the tracks.

You are correct Bertus. That board is a write-off. I am fabricating a replacement. Annoyingly the contact studs are the only thing I haven't been quickly able to source.

Duh. I'd like to think a night's sleep and a cup of coffee would have given me that idea. But you beat them to it, for which, thank you. Googling "pcb battery contact" led me to a number of potentially suitable alternatives. None are identical but several will do the job.

There are many everyday objects you could use there, like a brass nut, copper nail or washer, sawed up pre-1982 (all copper) US penny or for that matter machine them out of any (conductive and solderable) bulk material. For that matter you could probably just use a stainless steel bolt and nut and solder plate the area but not attempting to solder the stainless, rather just mechanical clamping. It wouldn't be as conductive but for 2 x AA should be okay, I did this to make a DIY MP3 player charging cradle back in the day.

Or a big ol' blob of solder... Or better still, plain gold-plated earing studs. But I was kinda hoping to preserve the manufactured look of the board, for purely aesthetic reasons.
