How many AMPs the battery should be for 560SEL 1989?
 

I wounder what is the best AMPs for the battery that I should install on my 560SEL 1989.

I don't know about the dynamo (alternator) but I guess it's 80 Ampere.

The original Mercedes battery is arround 100$ and it's 100 Ampere. Shall I buy it or buy the 75 Ampere one?

My last question, what is the best battery brand?

All W126's use the same battery. Interstates number is MTP-93.

Autozone's lists for $65
Interstates 84 month battery lists for $110
MB's is $110 also.

Take your pick all these work fine. Don't forget Sears Diehards as well.

I have bought replacement batteries for my '91 420SEL at both the local M-B dealer, and also Autolite/Exide brand at Kragens. I have been happier with the one from Kragen, and it is a lot cheaper as well ($69 versus $110 or $120). This is for a 84-month battery - I forget the cold-cranking amp rating. BTW the group number is 49 (for the correct size and terminal placement).

Where are you located? I'm guessing it's not the USA, because we use a different battery rating system. For example, the Interstate MTP-93 is rated at 850 CCA (cold cranking amps).

Buy the 100 ampere battery. It will last longer and give you stronger cold starts.

Consult with Mercedes agent, perhaps even obtain owner's manual.

Thank you guys for your replies. I live in Kuwait.
What I need to know is the battry AMPs [Ah] and I guess you answered me 93.

My Autozone battery says 1000 CCA's at 32F.

CCA are measured at 0F. CA is measured at 32F. Chances are, it's got 850 cold cranking amps.

Or, you can just walk into autozone and ask for the most powerful battery they have. Even the group 65's (Ford trucks) aren't as powerful.

Again thanks to all of you guys : ))..

I bought the original one that has 100 Ah, sorry not sure about the cold cranking amps but I guess more than 800 amp.

It's really good one and nice starting, tomorrow I'll try it on cold enshaa allah : ))..

What are the temps running in your neck of the woods? I have been told that it gets very cold over their at night.

Sorry sir but I didn't understand your question : ))..

He was asking how cold it gets at night.

ok i got it. It's about 18c (64.4 Fahrenheit). Not much cold in Kuwait.

I was just curious. Battery's are currantly a big topic in the northern states, since winter is here.
