Keep Your Basement Dry with a Healthy Battery

By Llya Ostashev

When talking to customers, I often get asked, “How do I get the most out of my battery? “The Basement Watchdog Battery is the heart of your backup system. Without a healthy battery, your backup system is useless when you lose power. Wouldn’t you want to keep your basement dry? Wouldn’t you want your battery to last for years? In order for these things to happen it’s important that you be proactive about maintaining your battery. If you neglect to do so, the battery will not be able to activate your pump during a power outage, causing your basement to no longer be dry.

I recommend that you create a schedule that will help remind you to care for your battery. Write yourself a note every 4-6 months to check on it. Remember, adding water is a very important step to having a healthy battery. Be sure to use only distilled water. Do not use tap water or drinking water, as the minerals may create buildup in the battery cells. You can purchase distilled water at most grocery stores. When adding water, fill it to the upper level mark on the outside of the battery or approximately an inch below the top of the opening of the battery cells. Make sure not to overfill your battery. Overfilling your battery can dilute the specific gravity of the battery, which can shorten its lifespan.
Quick tip: It is best to use a flashlight to help see into the battery to ensure you are not overfilling.

Another important step is to keep the battery terminals clean of corrosion. Corrosion is a chemical reaction that occurs when the battery is being charged. This will prevent the system from reading the battery properly and is very bad for the operation of the system. You can clean corroded terminals by using light sandpaper or a wired brush. Keeping the terminals clean will allow the system to keep your battery fully charged, which is key to making it through a power outage.

To help keep your basement dry, it is very important to take care of your battery. I would highly recommend keeping your schedule for adding distilled water and cleaning the terminals, making sure not to wait too long between times. It’s easy to consider inspecting the battery terminals whenever you check the fluid levels. Just keep in mind that taking good care of your battery will mean a more protected basement.
