Rodsob,

Since you engine starts easily, its hard to tell how much reserve your battery has.

Do a test yourself. Pull the GP wire out the relay and see how long your battery cranks the engine cold. If less than 30 seconds, you probably don't have enough reserve.

I have been using AUto Zone batteries and have had good service from them. $60 for a 7 year battery is a good deal to me. They have a group 49 battery which is what most MB use.
