Generac battery service done right, here in New Orleans
A dead battery is also the single most common finding on the annual visits we make, which is why a load test is built into every Generator Maintenance service we perform across the county — catching a fading cell in the fall beats discovering it during a January outage.
- Genuine OEM 12-volt Group 26R battery rated around 525 cold-cranking amps
- About a 3-year service life — freezing weather cuts cranking power fast
- Charging system tested, not just the battery swapped
- Terminals cleaned and treated; the old battery recycled responsibly
Why New Orleans trusts our battery replacement
Homeowners across New Orleans choose a professionally installed Generac for one simple reason: when the grid goes down, it just works.
OEM battery, correct CCA
We fit the exact group size and cold-cranking rating your model needs, so it spins the engine fast even on the coldest morning.
Tested, not just swapped
We check charging voltage and parasitic draw, so if something is killing your batteries early we catch it instead of selling you another battery.
Beat the cold-weather no-start
Replacing a tired battery before winter removes the single most likely cause of a generator that won't crank during an outage.
In and out, same day
A battery service is quick — we test, replace, treat the terminals, and confirm a strong start, usually in one short visit.
