Car- 1976 XJ-S

Is there any highly recommended battery for this car or should I just look at cranking amps and size?? I was planning on a red top optima.

Hi John,

Amazing! I was just on the Optima site looking for their recommended battery for my 1990 XJ-S since the Red Top is suppose to be a good solution for stored vehicles.
However, the web site (http://www.optimabatteries.com) does not list a battery for the XJ-S, just the XJ6 up to 1980. They do not officially offer a replacement for the standard vented battery. The reason is due to safety - if the charging system on the XJ-S were to fail and start over-charging the Optima battery, there would be no safe way of venting hydrogen gas from the boot area of the XJ-S.

Best,
Dwight
