Portable 12V 18Ah jump starter

The BatteryJack inc. Solar Booster Pac ES5000 is a sealed AGM battery rated at 12 volts and 18 ampere-hours. It serves as a direct OEM replacement for numerous legacy part numbers across security panels, UPS units, mobility scooters and emergency lighting. The unit arrives maintenance-free and ready for cyclic or standby duty.

Sealed AGM thermals and draw

Advanced AGM construction keeps the electrolyte absorbed, eliminating gassing during normal charge and discharge cycles. The sealed case operates silently with no moving parts, and self-discharge remains low enough for seasonal storage without trickle charging. Expected service life spans four to seven years under typical float conditions.

Nut-and-bolt terminals included

Each battery ships with nut-and-bolt terminal hardware so installers can secure ring lugs directly without adapters. The 100 percent OEM-compatible footprint matches the listed Powersonic, Panasonic, Yuasa and CSB cross-references, simplifying drop-in swaps. A two-year warranty covers defects in materials and workmanship.

Questions about this item

How do I install the ES5000 with nut-and-bolt terminals and what step is often missed?

Mount the 12V 18Ah AGM battery in the correct orientation, then tighten the supplied nut-and-bolt terminals securely; the step often missed is verifying polarity before the first connection.

What maintenance or replacement will the ES5000 need during its 4-7 year life?

The sealed AGM unit is maintenance-free; plan to replace the battery once it no longer holds a full charge, typically after four to seven years of service.

What limit appears first when the ES5000 is used repeatedly for jump-starts?

The 18Ah capacity and internal resistance of the AGM cells limit the number of consecutive cranking cycles before voltage drops below usable level.
