There are different kinds of batteries with different kinds of battery terminals. The higher the output, the heavy-duty the terminals get. The F1 and F2 terminals are used in batteries that go in on small toys, charger lights, razor scooters, electric wheelchairs, and UPS systems.
Let’s dive into their specs to have a closer look at them.
F1 vs f2 Battery Terminals
F1 Battery Terminal or Tab 187 Connector

The F1 battery terminals are found in SLA or Sealed Lead Acid batteries. This terminal sits on top of the battery most of the time. Sticking its head out with a bend on the end, it is done so for easy installation. It is a push-in installation process that requires no wire attachment. Push it in and it gets connected to the female connector for quick connection and disconnection. The F1 connector measures 0.187 inches or 4.75mm. Hence they are also called a TAB 187 connector. It is also called a Faston connector or a Blade terminal.
F2 Battery Terminal or Tab 250 Connector

The F2 battery terminals sit on top of Sealed Lead Acid batteries or SLA batteries. They come in pairs on a battery. The red one signifies the positive terminal and the black one as the negative terminal. F2 connectors are the same as F1 connectors. They differ in size. F2 terminals measure 0.25 inches or 6.35mm. That is why it is also referred to as a TAB 250 connector.
Difference Between F1 and F2 Battery Terminal
Both of the connectors serve the same purpose, supply power to your device. Due to their look-alike characteristics, you will have to pay close attention while changing the battery.
