  • 100 % OEM-compatible fit for direct UPS replacement

UPS Replacement Battery 12 V 18 Ah

This sealed lead-acid unit serves as a direct OEM replacement for uninterruptible power supplies and modified ride-on toys. It uses absorptive glass mat construction to deliver 18 Ah capacity at 12 V without maintenance.

Sustained Load Behaviour

The AGM design supplies steady service during extended discharge rather than only short bursts. Gas recombination exceeds 90 percent during normal use, so voltage remains stable throughout the battery's expected 4-7 year floating life.

Thermals Noise Power Draw

Sealed construction prevents electrolyte leakage in any orientation and eliminates the need for water top-ups. Silent operation with zero moving parts means no audible noise, while the maintenance-free design draws no parasitic power during standby.

Questions about this item

How much gas recombination does the 12 Volt 18AH AGM battery achieve during continuous daily use?

The sealed lead-acid cell recombines over 90% of gas generated in normal operation, so heat and pressure stay low even when the UPS runs all day.

Which terminal style does the 12 Volt 18AH replacement battery use so I can confirm my existing cables fit?

The battery follows standard UPS form factor with F2 faston tabs, letting it drop into most APC, CyberPower and Eaton units without new harnesses.

Will the 12 Volt 18AH AGM unit charge correctly on the float voltage of an older UPS designed for 7 AH cells?

Yes — the 100% OEM replacement design accepts the same float charge profile, so legacy chargers maintain it properly without adjustment.
