Hi guys,

it is right time to replace main battery..I know i know, this question probably been asked xxxx times here..but still, please, i need advice.

Main battery replacement - what i was able to retrieve when checked currently installed main battery in a boot - genuine MB, 70AH, VRLA..label worn off - this is much as i got here..

So guys - i am very confused, i want to ask few questions to clarify something;

Should i look after exact same 70AH - or it can be bigger, 95AH,100AH etc.?
Current battery is genuine MB - "VRLA"..i researched what is it..question is, should be VRLA type all the way - or, can be something else?

Any comments welcome, please guys give me a hand here.


Thank you.

most are 70ah, some higher spec ones are 90ah due to the toys onboard.

an 04 e class isnt a high value car anymore, just lob in a decent ish quality 70ah battery and enjoy the car.

Thank you for your replay;

you mean - any 70ah battery which fits regarding size, if it fits? or VRLA one.please?

Thanks

P.S. it is still very great to drive this car after so many years

70AH sounds much too low for a 320cdi.
Mine's something like 100AH.

Well, mine 1 is "half full" i believe..at the moment, sitting on genuine MB, 70AH one..

VRLA means it's a valve regulated battery which in normal use will not vent. Presumably chosen because you don't want hydrogen gas in the boot space. A VRLA can also accept a higher charging voltage which if the car is set up to provide might make a conventional battery gas - which you don't want in the boot space. At the very least I would check the charging voltage and ventilation provision before choosing a conventional battery.

My 211 is fully loaded and has a 100ah battery

Also a nice 211 will always be a high value car.

Just installed an Enduroline 019 AGM, it's 100AH. That's the closest and cheapest to the original MB one I could find. Although there are differeing opinions, the car is supplied from new with AGM batteries front and rear. Having said that, mine has run on a 70AH standard wet battery for the last year, but it wasn't up to the job AH-wise.
