Never a bad call to recheck wires etc
I always got jump leads, battery chargers etc, but for that extra peace of mind a friend recommended a particular portable battery charger
While it won't fix the underlying issue.
I found it useful as a "Get out of jail" card
Recommended one by a biker friend.
perfect size for a bike, fitted neatly under seat .
Bought in 2017..still working £55 Ish.
Size of one of those large phablet phones.
Light enough to carry in glove box
Charge at home via mains or in car by cigarette lighter
Jump start car, also useful for many other electrical devices.
Never used on bike
first use was poor chap in pc world car park.
Not starting so had flattened battery by time I walked over
Gave it a go ...and brum Brum in minutes.
Used on the civic a few winters back, before replacing battery.
Fired car up fine
My charger model not sold any more.
Halfords one very similar.
So
Amazon search may provide some help
Bigger numbers is better, read reviews + due diligence.
Might provide a little more confidence in future if you have battery issues.
Hope it's not needed.
