Battery terminals are the electrical contacts used to connect a battery to a charger or a load (a device that needs energy). These terminals have an extensive array of sizes, designs and characteristics. In this article we will be discussing the 14 most common Sealed Lead Acid Battery (SLAB) terminals.
1) F1 Faston Battery Terminal:
The F1 Battery Terminal is usually found on batteries used for home alarm systems, toy cars, fish finders and many other products. The position of F1 Terminal might vary between different types and sizes of batteries. The F1 terminal measures 3/16″ (0.187″) – 4.75mm wide. It is also knows as TAB 187.
2) F2 Faston Battery Terminal:
The F2 Battery Terminal is usually found on batteries used for UPS Systems. The F2 terminal measures 1/4″ (0.25″) – 6.35mm wide. F2 terminal positions are usually at the top of the battery. The F2 terminal is also known as TAB 250.
3) Faston Polarized terminal: There are two different terminals on this battery. Positive Terminal F2 and Negative terminal F1. A good example of this is the HR1224W battery. 
4) SP terminal:
The terminal on this battery is a spring. The negative and positive terminals are fully collapsible. This type of terminal is found in flashlights and lanterns.
5) WL terminal: Also known as the Insulated Wire Leads has the specifications of a) Molex Housing 5264-02 & 5263-PBT plug on PS-605 b) AMP Housing 1-480318-0 & 8116-1 on PS -1208. An example of this is the 12V 0.8Ah battery. This battery is commonly used in alarm systems and medical devices.
6) PC terminal:
PC is short for Pressure Contacts. The terminal on a PC battery is usually on the side, not at the top as with other terminals. This battery is commonly used in medical devices. An example of a PC Terminal battery is a PK12V2.3PC.
7) TH terminal: This is one of the two most common types of toy battery connectors.
8) TS terminal:
Another type of toy battery connector.
9) U terminal:
U terminal stands for Universal Automotive Post. This type of battery has a battery post with nut and bolt connectors connectors.
10) NB terminal:
The NB stands for Nut & Bolt. This is a very common battery terminal, an example of this is the 12V 18Ah – TLV12180 battery. There are some varieties of the NB terminal, NB1, NB2, NB3, NB4. The most common is NB. It’s a standardized terminal available on many batteries.
11) B, T6 terminal:
Threaded Insert 6mm stud. Notice the width of the terminal is 16mm. The stud is 6mm
12) T8 terminal: Threaded Insert 6mm stud. On the T8 terminal, the stud is also 6MM, but the the insert is 20mm wide.
13) T11 terminal: Threaded Insert 8mm stud. On the T11 battery terminal, the stud is 8mm. The terminal is 20mm wide.
14) T12 terminal -: Threaded Insert 5mm stud. On the T12 Terminal, the width is 12mm and the stud is 5mm.
