A battery backup system provides valuable protection for homes in areas prone to power outages during storms. With an average cost of $900, these systems help prevent potentially significant water damage and related expenses. Even preventing a single flooding incident can justify the investment, especially considering standard homeowner insurance policies don’t often cover flood damage.

Regular maintenance includes testing system operation by disconnecting the primary pump and verifying that the backup activates properly. Inspect battery terminals for corrosion and clean as needed. Check battery charge levels according to manufacturer recommendations. Standard batteries require replacement every three to five years, while deep-cycle batteries with proper maintenance can last up to 10 years. An annual professional inspection (approximately $250) helps ensure reliable operation.
