LampVPath (Pack of 4 14250 Battery Holder, 1/2AA Battery Holder, ER14250 Battery Holder, 1/2AA 3.6V Battery Holder with PCB Solder Mounting Lead

Hods batteries snugly but easy to add and remove the cells. Lead spacing seems to be standard.

This product worked great when retrofitting slot machines motherboards from soldered batteries to this product which makes battery replacement simple and pain free as once installed , no future soldering is required when batteries need replaced.

I ended up finding these direct from China, for about 20 cents each, rather than the $2 each. However, they did an important job, in letting me quickly prototype, and see if they would work. The wire legs are strong, long, and seemed to consistent among the 4. They have a bit of wiggle room, so adding them to a through-hold PCB shouldn't be much of an issue, provided the hole spacing is close enough. They hold the 14250 batteries I bought nicely as well - however, for long term use, I think I would find some way to fasten the battery to the holder, as the batteries are snug, but /not secure/ - and can pop out easily if jostled hard. The project I'm using these for does not have that issue as there's no "head room" for the battery to escape to. Other than now knowing they're 100 times more expensive than wholesale, or if needing them quick, or only a few - I'd buy these again in a heartbeat.
