Questions about this item

What size faston tab does the F1 terminal on this CSB GP-645F1 battery use?

The F1 terminal is a standard faston tab sized to mate with common quick-disconnect connectors used on alarm panels and UPS units.

Match the positive and negative markings on the battery to the panel's terminals; reversing them will prevent the alarm system from powering up.
