I have often heard about trickle chargers and how they save your battery over the winter.
I have to admit,I have never used one and have had no issues with my batteries being charged enough to start my bikes.
I live in Colorado, so not much more than a month or so will go by without it being nice enough to ride,my bikes are in a completely enclosed garage that is not heated. When there are continuous days that will be warm start to show up(another couple of months,I will charge them up and ride all season with no problems.
Batteries generally last about 3+ years.
Should I be concerned about leaving a trickle charge on those weeks to a month that I am not riding them?
For those using trickle chargers,how long do your batteries generally last?
