An unsecured battery can be unsafe and costly. How do you secure a marine battery? Try a battery hold down.
Battery hold downs can at most times, be just as important as the cables themselves. If a battery is allowed to move and jostle around where it’s been installed, it will cause damage not only on the outside, but also internally. Damage inside the battery can greatly reduce the life and performance of the battery, so protect your battery. A battery box will keep in any acid spells and gasses; it will also keep water out and could prevent any potential heath dangers.
