Summary: The battery on this page is the Optima RTS-2.1, aimed at cars and vans. Technology matters here: it is a spiral-cell AGM battery.
Rated 50Ah 6V 815A, the Optima RTS-2.1 replaces the original in plenty of cars and vans. The figures for the Optima RTS-2.1 are copied from the maker's data, so you can compare like with like. The search box at baterias.online accepts the brand followed by the code, nothing else needed.
50Ah is right in the usual range for cars and vans. Big diesels and cold climates appreciate the 815A on offer here.
A teenager's first car, used twice a week, rarely keeps its battery happy. Match the spiral-cell AGM technology of the original rather than swapping to a different type. A rotten-egg smell near the battery points to overcharging.
The six-cylinder shape is the trademark of spiral cells. Winches, light bars and audio systems pair well with dual-purpose spiral batteries. Secure spiral batteries with proper brackets.
It belongs to OPTIMA RED TOP. If you need a different size with the same construction, look within that range.
