Re: battery replacement
Caution: there is a difference between a battery tender or float charger and a battery charger. The former will cycle on and off to maintain the battery at full charge. A battery charger will continue to pump juice into a battery regardless of charge level, and can overcharge and damage the battery. You can find float chargers online for under $10. I bought four on sale years ago and keep them on my three stored cars and motorcycle battery all winter.
