I usually get decent brand motorcycle batteries but I’ve had a battery on my Mv agusta wghich i rarely use and the batteries only 18 month /2 years old and the batteries goosed I’ve priced up a yuasa one and it’s 80 quidish but I can get this Lucas compatible one for £30, which if it’s goosed after a year or so isn’t as bad as spending 80 on one anybody had one or similar https://www.ebay.co.uk/itm/360849057493
That battery is only 7 Ah and 130 CCA. A but low for your MV. I bought this one and that works fine for me.https://www.ebay.co.uk/itm/EXIDE-AG...-/202395004359?_trksid=p2349624.m46890.l49286 I generally buy the cheapest battery with the highest CCA I can find. That way I get 2 batteries for the price of 1 Yuasa
If you do not look after any battery and keep it properly charged on a decent maintenance charger, it will always fail. Especially so with sealed batteries Yuasa and GS will always have more stamina than cheap batteries, because GS-Yuasa always use only new lead in their plates...they have no contaminants in the recycled lead like in the cheap batteries (which is partly why they are cheap) You get what you pay for, but like Ducati's themselves...they still need looking after properly or they fail
I’ve a few bikes so it’s hard to keep all the batteries charged all time but I’ll try and keep up with them a bit better
