Re: What Battery for my 166?
Hi Redalf, use the physically largest one that will fit. You can simply measure the available size. Battery should be 12V obviously. It will not do any harm to use a battery with a larger capacity (Ah) than specified but it probably won´t do any good either. It´s like a bankaccount: there won´t be more money on the account than what you deposit. If you do want the exact size specified by the factory, I think the specification (Ah) can be looked up in the manual. Be sure to have the code for the ICU which you´ll need after installing a new battery. BtW if the current battery is doing the job OK I would not change it.
