IF the vehicle will be outside in the sun, then you can use one of those small solar voltaic panels that plug into the cigar/accessory socket and are intended specifically for maintaining a battery's charge. Just set the panel on top of the dashboard top panel and plug it into the cigar lighter outlet.
Indefinitely.
Yes it has a 2amp trickle charge
Yes, that is the purpose of a trickle charger. Just make sure it is an automatic charger that comes on when needed and then stops charging when the battery is fully charged. You can leave it on a battery for years if need be.
It is not advisable to leave a trickle charger on your battery when starting the vehicle.
pick up a trickle charger from your local motorcycle shop. i leave it on overnight and it is charged in the morning.
Nothing you have to do. It will be fine sitting for 1 month. If you plan on storing it for 3 or more months then put a trickle charger on it and leave it connected.
Use of "Trickle" type Battery ChargersIF you're talking about automotive battery applications, and it is truly a trickle charger, then the charger and cables can be left attached to the battery, and it should keep the battery at max voltage. IF however, the charger puts out more voltage than a true trickle charger, then the battery could be damaged by "overcharging."
Any car charger will do. I recommend that you use a trickle charger rather than a jump charger. Also, look into a Battery Tender which will not only charge your battery at a proper pace, but you can leave it plugged in an the Battery Tender will maintain your battery for you so that it never becomes low again.
yes if you leave it for about 2 months it will eventually die
leave the camera so when you next turn it on and charge it, it will charge.
You Charge it by putting it on the charger before you leave.
