BatteryJack SH1228W 12V 9AH SLA Battery

The BatteryJack SH1228W is a 12V 9AH sealed lead-acid battery built with AGM technology for maintenance-free operation. It serves as a direct OEM replacement in uninterruptible power supplies, backup systems and compatible power tools. The sealed construction prevents electrolyte leakage and allows safe use in any orientation. It is classified as non-spillable for transport.

AGM sealed lead-acid practical limits

AGM sealed lead-acid chemistry delivers reliable standby power but offers lower energy density than lithium alternatives. The expected service life ranges from four to seven years depending on temperature and depth of discharge. Gas recombination exceeds 90 percent during normal use, yet the battery cannot be fast-charged like modern chemistries. Capacity will gradually decline with repeated deep cycles.

Verify voltage terminal type

Confirm that your device requires a 12V 9AH SLA unit with T2 terminals. The physical footprint measures 5.94 in length, 2.56 in width and 3.72 in height, weighing 13.16 lbs. Check the available space and terminal clearance in your UPS or tool chassis. Ensure the charging circuit is designed for sealed lead-acid batteries.

Questions about this item

Should I pick the 9AH version or a different capacity for my UPS?

Choose the 9AH model when your device specifies a 12V 9AH battery; a higher or lower amp-hour rating will change runtime and may not fit the compartment.

What does the 12V 9AH rating deliver in a real UPS or backup unit?

It supplies 12 volts nominal and can provide 9 amps for one hour or proportionally less current for longer periods, matching the runtime your equipment was designed for.

How do the T2 terminals connect and what current can they handle in practice?

The T2 terminals are blade-style faston tabs that slide onto matching connectors; they are rated for the battery's full 9AH discharge capability in standard UPS and backup applications.
