12V 18Ah AGM battery

The BatteryJack inc. HR22-12 is a sealed 12 volt, 18 amp hour AGM battery built for jump starters, battery chargers and portable power units. It uses absorptive glass mat technology to deliver maintenance-free operation in any mounting position. The non-spillable design meets International Air Transport Association requirements for safe transport. It serves as a 100 percent OEM replacement for compatible equipment.

Upgrading from flooded or lower-capacity units

This battery replaces older flooded lead-acid units that require water top-ups and upright mounting. The jump is worth it when you need a maintenance-free block that recombines over 90 percent of generated gas and eliminates electrolyte leakage risk. The sealed construction also allows operation on its side or end without acid spills. Buyers who need a higher amp-hour rating than 18Ah must select a different model.

Capacity and runtime headroom

The 18Ah rating supplies steady service for backup devices, portable chargers and jump starter packs within its designed load range. Expected floating life spans 4 to 7 years depending on application and temperature. Runtime ends when the connected load exceeds the battery's discharge capability or when the voltage drops below the device cutoff. Units demanding more than 18 amp hours of capacity will drain this block faster than intended.
