When it comes to winterizing
your RV or boat, ensuring the health of your battery is one of the most
important steps to take. Freezing temperatures and extended periods of
inactivity can lead to costly battery damage or even a complete battery failure
by spring. Here’s a comprehensive guide on how to protect your RV and boat
batteries during winter storage, so you can get back to your adventures as soon
as the weather warms up.
A fully charged battery is better equipped to handle cold temperatures.
Battery electrolytes freeze at lower temperatures when charged compared to when
they’re partially or fully discharged. Before storing your RV or boat, make
sure the battery is fully charged to reduce the risk of freezing and ensure
it's ready to go when you return.
Dirt, corrosion, and debris can cause battery terminals to lose connection
over time, which may lead to a dead battery by spring. Clean your battery and
terminals using a solution of baking soda and water, and scrub off any
corrosion with a wire brush. Rinse thoroughly and dry before storage, ensuring
a clean, strong connection. Click HERE to

Even when not in use, RVs and boats have small electrical draws that can
drain the battery over time. To prevent this, disconnect the battery cables
once your vehicle is in storage. This will minimize the drain and help retain
the charge for longer.
If you live in an area with harsh winters, consider removing the battery and
storing it in a warmer environment, like a garage or basement. Keep the battery
off the concrete floor, as this can accelerate discharge; instead, place it on
a wooden board or shelf.
Batteries perform best when stored at moderate temperatures. Extreme cold
can cause the battery’s electrolyte to freeze and expand, potentially cracking
the case or damaging internal components. If you’re storing your RV or boat in
a colder climate, look for a storage facility with temperature-controlled units
to protect the battery and other sensitive equipment.
A battery
tender, or trickle charger, keeps your battery charged throughout the
winter without overcharging it. These devices deliver a low current that
maintains the battery’s charge, making them ideal for long-term storage. Be
sure to choose one that’s compatible with your battery type and check in on it
periodically during the winter months.
If you have a flooded lead-acid battery, check the water levels before
storage. Top off with distilled water if needed, ensuring that the battery’s
cells are fully covered. This will prevent the plates from being exposed,
reducing the risk of damage and prolonging battery life.
Finally, before taking your RV or boat out of storage, inspect and test the
battery. Ensure there are no signs of corrosion, leaks, or damage. Charge it
fully if needed, and run a quick test to confirm it’s holding a charge
properly. This extra step can save you time and hassle when you’re ready to hit
the road or water again.
By following these steps, you can protect your RV or boat battery throughout
the winter, ensuring it’s ready to power up your adventures as soon as the
season turns. Winter storage doesn’t have to be a challenge – with a little
extra care, your battery will stay strong and reliable year after year.
