Camleion QTY100 F1 to F2 and F2 to F1 Sealed Lead Acid Battery Terminal Adapters (50 Per Adapter) 0.250 to 0.187 and 0.187 to 0.250 Battery Terminal Adapter with Plastic Storage Case

I liked the ease in using these connectors. There were F1 to F2 and F2 to F1 connectors and it did not require any special tools to put these connectors on. If your battery has either F1 or F2 terminals, it does not matter which type are needed. I would recommend these connectors.

My alarm system needed a new battery. I had a new battery but the prongs were too large. These connections solved the problem.

The adapters do their job however they could be better. The metal is soft and it bends easily. I've used terminal adapters made decades ago that were much stronger. Again these work, just be careful not to bend them. Older units were made of spring steel. These are made of soft steel. There is no spring to these.

Proper material, size and crimps for the 12 of each that I used. Just the right amount of effort needed to install.Arrived in individual bags in the case, and the case is better than average (it latches).

When you need these things, you really need them! It took me a year to think of a search term that found them for me. Before I found, I was spending time making jumpers.
