Thanks for the information 👍, just had a same issue today with my 2014 b 180, could you please let me know is main battery circuit under the bonnet needs to be disconnected before changing this auxiliary battery ?
I bought a compatible auxiliary battery for my B class but it has no exhaust hole to connect to the pipe, is it ok to let the exhaust pipe just loosely there? Pls give me some advice, thanks.
Hi, I'm not sure if the battery model you replaced is correct. If it is correct, there should be a exhaust. For safety reasons, there will be chemical reactions during the charging and discharging of the battery, so you need to install the exhaust pipe as required.
