Electrically there is no reason why not .
If you are asking the question, can you charge a 6 volt battery with a 12 volt charger, the answer is no.
If it is a 12 volt marine battery, then yes. If it's a 6 volt marine battery, then you would need two of them wired in series to make the 12 volts needed to start the vehicle.
The first thing you need to know is if the truck is still the original six volt system or not. The charger is still hooked pos to pos, neg to neg regardless of whether it is pos or neg ground. Do not use a twelve volt charger on a six volt battery.
With any 12 volt battery charger.
Buying a six volt battery is better than 12 volt. If you buy the 6 volt takes up less power so it holds more.
They are all 12 volt. i charge my marine battery for 6 to 8 hrs. on 6 volt. the less voltage with a longer time is best. the faster the charge the more the lead plates in the battery disintegrate. slow and easy for long life of any battery
It varies widely from around 300 on a small car to over 1000 on a truck battery.
12 volt batteries if fully charged should show 14.2 volts
It is in the truck under the 'cover' near the spare tire, there should be another cover over the battery as well.
Yes they will work, golf cart battery have a few more plates in them for longer run time.
No
if it is any think over 1 volt it is not a cell battery it is just a 6 volt battery if you had a 1 volt then it would be a cell battery
