Battery removal A122

Hi I have a simple question and have searched the answer to no avail.

How do I remove my A122 battery for the Winter (take hot connection off before neutral, the other way around or does it not matter?)?

I also heard that I need to keep my battery charged through the Winter, how do I simply do this this (I do not own a trickle charger)?

Thank you!

I do the ground first, then the positive.

Battery MINDer | 12v 1.5 Amp Battery Charger, Maintainer, & Conditioner

The battery is removed from the camper and stored in the garage while the BT Jr. is connected. My battery life has been greatly extended by using my BT Jr. all winter. Keeps the battery fully charged and prevents sulfating, a big killer of lead-acid batteries.
I bought that because I plan on installing at least one more battery three would be better but real spendy, the battery minder will handle up to four.

Yeah, I think the BT Jr can handle just the one batt.

Perhaps this is a naive newbie question, but I am curious. Is there any downside to simply leaving the camper connected to shore power in the winter in order to keep the battery charged? The only thing I can see is that I won't get the de-sulfating benefit.

Similarly, I am considering leaving it set up in my driveway for use as a guest room in the winter. It's already winterized, so no worries about freezing. It can snow a bit here, but it doesn't appear that snow load should be an issue, between the pitch of the roof and the structural design. Any opinions or experience with this?

Not yet!
The old camper I had never leaked any that I could find.
This is my first winter with this trailer so I will keep a sharp eye out for leaks and then take it to the dealer if need be.

The reason that the neg should be DCed first.... If in the process of disconnecting the first post, the wrench should touch a metal surface - the surface would be naturally be grounded. A circuit through the wrench ground (at the neg post) to ground (on camper metal) would cause no arc... Conversely, a circuit through the wrench POSITIVE (at the battery positive post) to ground ( camper body metal) would result in a dead short acctroo the full battery!!! Over a hundred amps!!! Severe burns when the arc flash occurred... Burns from the red hot wrench... Possible acid burns from an exploding battery!!! Yup, I would disco the neg first!!!

Welcome to the forum, BuckeyeJeeper.

Let me add that when disconnecting a battery, make sure to move the wire away from the terminal so it can't fall back on it and inadvertently reestablish the connection. That can lead to an unpleasantly negative surprise.

Thank you for the replies. I just took the battery off of the trailer without a problem. When connecting it up again in Spring should I connect the positive side first?
