Battery Charger Connection help

I have a 2012 Winnebago Via Class A Sprinter 3500 diesel engine. I forgot to disconnect the chassis battery and had to jump it and it started right up.

I have this charger, Battery Tender Power plus 3 Amp Charger, 6V and 12V. My question is, do I need to take the battery out of the floor (drivers side) to charge it or can I charge it the same way I jumped it?

Plug the charger into the wall and hook it up to the positive cable and the ground rod? Let it set and charge for a day or two?

Thanks

I

There's no reason you can't just hook up a charger like you would with your car. You don't need to take the battery out.
Are you sure you don't have a boost switch that would have got you going with out jumping?
Good luck.

You can even wire it up solid, and leave it there all the time.

That way whenever you hook up to 120 volts, it will charge and maintain it.

This is if you have it stored and powered up.

How long with it take to charge? I was afraid to let it hooked up in the rain so I took it loose after about 4 hours and it was not reading green, but yellow. It did start easy.

At 3 amps it will likely take over 24 hours.

You can check the state of charge by unhooking the charger and letting the voltage stabilize for 5 to 6 hours, then check the voltage.

There are charts giving state of charge (SOC) you can find on the internet. I will see if I can find one.

The SOC is only one thing to check. You will also need to know the capacity of the batteries. As they age and are charged and drained (cycled) they will loose capacity.

Here's a SOC table. Remember that you have to let the battery rest or discharge it for a short time to get rid of the surface charge.
