Adding Electrolyte to Motorcycle or ATV Battery

Hello Kip, it seems anymore when you buy an ATV or motorcycle battery they come in a box with a container of fluid that needs to be put in the battery. I was wondering how long do you need to charge the battery after putting what i believe is electrolyte in it? Some people have told me its ready to go after putting the electrolyte in the battery. The instructions leave a lot to be desired if you ask me.

Mark, you ask a good question that a lot of people don’t seem to fully grasp. We’ll start with answering the question in reference to the fluid inside the container. You are correct in assuming its electrolyte (acid) inside the container. Once the electrolyte is poured into the cells of the battery, it starts a reaction inside the battery. You will get some gassing  due  to  the  release  of  carbon  dioxide  that  is  a product of the drying process of the hydrogen sulfide produced by the presence of free sulfur. Therefore, the filling  operations  should  be  in  a  well-ventilated  area. These gases and odors are normal and are no cause for alarm. The battery is approximately 80% charged after adding the electrolyte to the battery. The battery 9 times out of 10 will have enough CCA at that point to start the ATV or motorcycle. Now with that being said, you should put the battery on a battery maintainer overnight to bring the battery to 100%. Never use a auto car charger to charge a motorcycle or atv battery. These types of chargers are often to big for motorcycle and ATV batteries and will boil the electrolyte inside the battery. Now if your going to ride your ATV or motorcycle for 2 to 3 hours with no interruptions it will be fully charged on its own. Remember Mark, always wear safety goggles and rubber gloves when working with batteries. You do not want a battery to explode in your face or get sulfuric acid on your skin.
