Mercedes O305 (OH1316) battery type?

Post by busface »

Hello, I’m looking to buy my first bus (1984 O305) but the batteries were recently stolen and the current owner doesn’t know the exact type to replace them. Does anyone know the specs of what I need? I understand it has two batteries.

If anyone has a PDF of the user manual that I could buy please let me know!

Many thanks in advance.

Another bit of info - there appears to be space for two batteries but only terminals for one.

There would be 2x 12v batteries connected in series to give 24v output. You will need a connector cable between them.

Thanks Boronia - any idea what Ah rating they’d need to be? Each battery bay is 20cm X 31.5cm so I guess I could try narrow down the type based on fitting to that size?

I don't know specifically. I'd suggest you talk to a battery specialist. They'd need to know the orientation of the terminals (eg both at one end or opposite ends)

Perfect, thanks so much for the info I really appreciate it. I found a post on another forum which has some info from the OM366a user manual that specifies 2 X 55Ah batteries, or optionally 2 X 70Ah batteries: https://www.benzworld.org/threads/om-36 ... e.3074614/

If you are not using the bus regularly, I would suggest getting a battery charger/maintainer, like C-Tek, to keep connected while parked up.
