Pramac Generator Battery
The BatteryJack 12V 18AH AGM battery serves as a direct replacement for Pramac generator models. It uses sealed absorbed glass mat technology that requires no fluid checks or maintenance during its service life. The unit arrives ready to install with nut and bolt terminals included.
18AH Capacity Match
This battery delivers an 18 ampere-hour rating at 12 volts, matching the original Power Sonic PS-12180 specification. Builders must verify that their generator requires exactly this capacity because the physical case size and terminal layout are built around the 18AH form factor.
Sealed AGM Operation
The sealed AGM construction prevents acid leaks and allows operation in any orientation without venting gases. Internal resistance stays low under normal float charge, so the battery runs cool and silent in standby use. Expected service life spans four to seven years in backup applications.

Questions about this item
What does the 18AH rating mean when the battery is installed in my Pramac generator?
The 18AH rating indicates the battery can deliver a steady current for a defined period, giving your generator enough reserve capacity to crank the engine and run the control electronics during start-up.
The terminals are described as nut and bolt — what connection standard does that follow and what gauge cable does it accept?
The nut-and-bolt posts use a standard M6 thread common on AGM batteries of this size, accepting ring terminals crimped to cables up to 6 AWG for a secure, low-resistance connection.
Will the 7.13 × 3.00 × 6.6 inch case fit the battery tray on my Pramac unit without modification?
The case matches the Power Sonic PS-12180 footprint exactly, so it drops into the original Pramac tray and the hold-down bracket lines up with the existing mounting points.
