It is that time of year here in upstate NY to winterize the trailer. Had a great season if you don't count the two hurricanes which led to early departures from our campsites.
Here is my question. Each year I remove the battery and store it in the basement. In May I will bring it up and start using a trickle charger to get it ready. I was told that I should also check the water level each month (over the winter) and add water as needed. I have only added water once to the battery but now I am wondering if I need to do more, and how often and how much distilled water. Any information or advice is appreciated.
