I bought a booster from Amazon for my Suzuki 400 Burgmans. I wanted the security knowing I could self rescue if I played my radio too long. The booster looks something like this: https://www.amazon.ca/Arteck-12000mA...857862&sr=8-25

It turns out this capacity booster seems OK for a Mirage engine. My 2017 battery went flaky from abuse, only starting the car in warmer temps and failing miserably at anything below 50F.
