If you have a motorcycle, it is good to use the trickle charger to keep the
battery from dying down when you are not using it for long intervals. (Also
good to recharge and check the battery before replacement. A New battery
also needs to be charged to full capacity before installation)
A Trickle charger intelligently does this by monitoring the output voltage
of the (Lead acid battery).

price elsewhere ~$36.
(In case you are wondering the difference between this and Battery tender is
amperage of charging. Junior outputs 0.75A, the other one 1.25A. But deal
is only on Junior)
Shipping is free for prime, but you can use fillers to get to $25 for free
shipping anyway. One suggested accessory is the 25f extension cable (so that
you dont have to remove the battery from your bike) for $10.93
