Optima RTS-4.2 in everyday use
A car parked under a streetlight for a fortnight can greet you with silence. A memory saver plugged into the 12-volt socket keeps radio codes and window settings alive during the swap. Batteries rarely fail on a warm day; winter usually exposes them.
Optima RTS-4.2 for cars and vans
Drivers who search for Optima RTS-4.2 usually have the old battery right in front of them, code and all. On paper it reads 50Ah 12V 815A, which is what most drivers compare first. Comparing batteries online side by side rules out the wrong size in seconds.
Nothing unusual about 50Ah: a standard capacity for cars and vans. 815A of cold cranking current is strong for a battery of this size.
Questions buyers ask about the Optima RTS-4.2
Will both the size and terminals match?
Compare 254 × 175 × 200 mm with your tray and check the old battery is also positive on the left-hand side.
Can a battery be stored before use?
Store it fully charged, away from heat and frost, and give it a refresh charge before installation.
Five checks for a perfect fit
- ✓ The capacity rating, 50Ah, should suit the consumers you run. Lots of electrical equipment calls for the higher end.
- ✓ Cold cranking 815A: compare with your handbook's requirement.
- ✓ Technology to match: spiral-cell AGM. Moving to a different chemistry may need settings changed in your system.
