Terminal Adapter, F1 to F2 (50 PER)-Adapter

Perfect for when you're replacing a UPS battery and has the F1 connectors and the new batteries always seem to come in with F2...

Wanted to like these, connectors not tight enough, they move too much. Very loose connections, had to remove & not use.

They did the job at a good price. I wish I could have gotten them to clip on tighter. They could move a little when attached to a connector.

Terminals arrived on time and as advertised. They fit my batteries perfectly and are a much better value than buying in bags of 5 at the auto parts store.

Sadly, these are utterly worthless! It's hard to find 12V 7Ah batteries with .25 terminals, but many UPS units use exactly that: F2 terminals on 1207 batteries. The only batteries available are extremely expensive, and in my opinion, vastly inferior with price considered. Yet, these terminal adapters simply don't fit! The F1 side is too wide and thin, so when attached, does not maintain reasonable contact. The F2 side is too thin to clamp those terminals, either! Then, the combination of terminal and adapter often is too long for the battery to fit back into the cramped space available.

Well made. These are what you need to convert F1 connector to a F2 connector typical used on sealed lead acid batteries in UPS for PCs.

The metal is thin and easily bent. There is not a lot of options for such adapters and this one is not great. A lot better just to recrimp cables.

These are unfortunately very loose on the F1 side. I'm not sure if they were made wrong or for some obscure terminal spec between F1 and F2. I ended up having to tack them in place with some solder, because they were moving so much that power was being interrupted. They work for my needs, but when these are used up I'll be buying something else.
