12 V 18 Ah AGM Deep-Cycle Battery

The BatteryJack CB19-12 is a sealed lead-acid battery built with absorptive glass mat technology. It delivers 12 volts and 18 ampere-hours of capacity for standby and cyclic use. The maintenance-free design requires no watering or specific-gravity checks during its service life. It is classified as non-spillable for safe transport and operation in any orientation.

Suits UPS Backup And Standby Power

This unit fits users who need a direct 100 percent OEM replacement for existing 12 V 18 Ah packs in UPS units, alarm panels or emergency lighting. Buyers who want more storage capacity or a different voltage should look at other models. The gas-recombination system handles over 90 percent of generated gas under normal floating charge. Expected floating life spans four to seven years depending on application.

Check Terminal Layout And Dimensions

Before ordering, verify that the physical case size and terminal arrangement match the equipment you are replacing. Confirm the charger or UPS is programmed for AGM charge profiles rather than flooded-cell settings. Ensure the installation location allows the battery to operate within its specified temperature range. The three-year warranty covers UPS and backup devices while other uses carry a two-year term.

Questions about this item

What voltage system must my device use for this 12V battery to work?

Your equipment must operate on a 12 volt DC system; the battery is rated at 12 volts and 18 ampere-hours.

Can I keep my existing charger when replacing an older sealed lead-acid unit with this AGM model?

Yes, provided the charger is designed for 12 volt AGM or sealed lead-acid chemistry and its voltage limits match the battery specifications.

How can I confirm the battery is performing correctly after installation?

Measure the open-circuit voltage with a multimeter; a fully charged unit should read at the rated 12 volts, and the device should run for the expected duration based on the 18 ampere-hour capacity.
