I was looking at buying a Duracell D2A 2 AMP 12V Battery Maintainer / Charger to use during cold weather months to keep a level charge on things that are not being used like the lawn tractor battery and the motorcycle battery. I have never used one of these trickly type chargers that you leave hooked up to your equipment all the time. Just wondering - do you have to disconnect the battery from machine, or can you leave the positive & negative cables from the vehicle hooked up to the battery while the trickle charger is connected and working ? I did not know if the constant positive charge going in from the slow charger would cause a problem with the vehicle's electrical system if left hooked up to the engine. Thanks for the help !
Thanks Frank, thats exactly what I wanted to know - good deal.
You can leave the cables connected. As long as the key is off, the charge will only be going to the battery. Most trickle chargers will cut off when the full charge is complete. Mine will kick back on when the battery needs more charge.
If you are only getting one charger, you will probably want to change from one battery to the other about every 2 or 3 weeks.
