advice needed on new battery for w124
 

Well, the battery on my 87 300e crapped out yesterday. Any advice on buying a new one? Any particular brand or type better than another? Thanx everybody. p.s. I run a small amp off my battery, if that makes a difference.

Get a Optima battery from autozone or a Die Hard from Sears.

There's been a lot of discussion on this subject.

Here's a link to one of the threads:
Optima Batteries

Try searching using "Optima Batteries", "Johnson Controls". You'll get lots of info.

The 124 and 201 gasoline engines use a Group 48 battery as OE, but a Group 26R will fit perfectly and has plenty of cranking power eventhough it is several pounds lighter that the OE Group 48. The 26R is a common size and the type sold by Costco, Pep Boys, and Autozone are all identical and manufactured by Johnson Controls. They cost about $40 and have about a four year warranty, but last seven to ten years in the mild So Cal Climate I live in. If you peel off the stick on labels, they become unobtrusive plain black batteries.

A modern medium priced 26R is about 525 CCA. The OE Group 48 was 495.
