Hey guys, Had a few issues with my Mutt battery since I bought it ~9 months ago. Doesn’t seem to hold its charge for more than a few days. The battery currently in there is “MT battery cb7-A part number 712071” https://secure.bitzforbikes.co.uk/photo/images/supplier/hilevel/products/712071/listing/712071.jpg Thinking of replacing/upgrading. Anyone have any recommendations... motobatt? Also very confused over which one I need. Any advice hugely appreciated. Also feel like I should invest in a trickle charger. Again, any reco’s hugely appreciated. And also advice on how to use/how often to use. Thanks again!
