What battery is this?

[AC123]

Hi

Need to replace the boot battery in my SL500. Loathed to pay dealer prices so wonder whether anyone can tell me what battery it is so I can get one from a local motor factors?

Thanks

Guessing at your car it's probably this one or similar. I don't think GSF are open today but they're my main choice - unless you want to pay halfrauds to fit it today. GSF also do an on line discount code for Pistonheaders; 25% off with PISTON25.

Looks like you need a heavy-duty 096 battery, I'd go for a Varta (same as MB/Bosch) ...

Careful there, that's no ordinary battery. It's an AGM type (absorbent glass mat) specially made for cars with stop/start systems and/or regenerative braking. If your car is fitted with either of these systems an ordinary lead-acid battery will not do. I would look for the same battery again which is an exide EK700. You will find it is a lot dearer than the ordinary battery.

Hi

It's not fitted with start stop or anything like that - this (I believe) powers all the electrics in the car though.

What would happen if a normal lead battery was used? I could do with saving money if possible, but if it's going to knacker something than it's obviously a daft thing to do.

Thanks

Any motor factors will be able to tell you what should be fitted from the registration number...

It'll be an AGM battery because it is inside the car. Performance wise a normal battery will be fine but you should be consider the fact that it could vent or spill acid in the boot.

If Merc spent the extra to fit an AGM then you can guess there was a reason for it. As stated above AGM batteries do not gas when charged like a normal battery and as the battery is in the boot and could leak gasses in to the cabin then I would fit the AGM battery. Also they are designed to do about 9-10 times the start cycles a regular battery does so will last longer if that helps ease the pain of the extra cost
