LiftMaster A12330SGLPK battery replacement.
High quality compatible replacement battery for LiftMaster A12330SGLPK gate opener, 12v sealed AGM batteries.

Being a sealed AGM unit, there's no electrolyte to check or top up, which suits equipment that often sits outdoors with limited access. Still, how it's charged matters for lifespan: let the system bring it back to full after every outage or heavy cycle of use rather than leaving it partially drained, and if the gate operator is going into storage or seasonal downtime, give the battery a top-up charge about once a month so it doesn't settle into a deep-discharge state.
Once this battery eventually wears out, it doesn't belong in general waste. Lead-acid AGM batteries are built almost entirely from recoverable materials, and the lead, plastic casing, and electrolyte all get reclaimed through standard battery recycling channels, so an old unit should go to a recycling point or a retailer that runs a take-back scheme rather than the bin.
For gate systems that draw down harder or need longer runtime between charges, a higher-capacity AGM version of this battery is also available. It drops into the same control box using the same connections, just with extra reserve capacity built in for sites that need more backup time per outage.
