Optima XM not charging battery - fit aux battery? in !!..DIY Installers..!! Posted December 4, 2018 We have a 20 year old Optima XM, which works fine, except it does not charge the battery. I presume it needs a new main board to correct this. I wondered if permanantly connecting an external trickle charger to the battery would fix this, without causing any problems? I would welcome any advice on this. Thanks
