About Optima Batteries
Optima Batteries have an easily decoded UK part number system. All part numbers have three letters and a floating point number.
The first two letters signify the range:
- RT - Red Top
- YT - Yellow Top
- BT - Blue Top
The following letter signifies the terminal type:
- An 'S' signifies standard SAE round posts in the standard orientation (positive left).
- An 'R' designates standard SAE posts, but reversed layout (positive right).
- A 'C' dictates that the terminals are SAE but down the centre line of the battery.
- A 'U' signifies that it has universal terminals: both standard and side screw-in terminals (common on USA cars).
The floating post (decimal) number after the three letters indicates the volume of the battery in litres. Common sizes are 3.7, 4.2 and 5.5. The higher this number, the larger the battery an the associated power ratings.
Optima Batteries are specialist AGM batteries designed for use in extreme conditions. They have a unique patented Spiralcell technology that leads to an unusual cylindrical shape of the individual cells. The part numbers reflect the cylindrical shape by being based around the litre volume of the batteries. E.g. The Optima 4.2 range are 4.2 litres in volume. Being AGM, all Optima batteries are completely spill proof and safe to handle.
