Long story short, I came up to Sydney recently for what was supposed to be 2 weeks. This is more likely to be months now. I'm expecting when I get home my motorbike battery will be dead as a dodo from lack of use.
II had it fail to start about a month ago after riding dropped from daily to once every few weeks with the lockdown, too.
So, I'm looking at mobile jump starters. Specs and prices are all over the place for these things.
Anything from 400 amps to 2,400 amps. In the handheld/battery styles ones anything from 3,000mAh to 18,000mAh.
As I understand the basics, the started will only draw what it needs. More amps are needed for larger engines, but as long as there are enough the actually amps doesn't matter.
I'm not really sure how mAh or amp hours is relevant when you're only using it for a few seconds. is 1 amp hour, 60 amp minutes, or a 3600 amp second? Not sure if they can supply power like that, as by that math some of the bigger units would have colossal amperage available for the second it takes to turn over a motor, more than you could ever need.
For a motorbike battery, is something like this $35 portable unit the go?

Am I getting anything for the extra money in the case of having it on hand to start a bike?
