  • 100% OEM replacement matches PXL12072 and LC-R127R2P1 specifications
  • Four-pack format supports multi-battery installations

12V 7.4Ah SLA 4-pack

This pack supplies four 12-volt 7.4Ah sealed lead-acid batteries built with absorptive glass mat technology. They serve as direct OEM replacements for UPS units, alarm panels, emergency lighting and similar backup power applications. The maintenance-free design eliminates watering or specific-gravity checks. Each unit arrives new and ready for immediate installation.

Sustained backup performance

The AGM construction absorbs electrolyte in fine glass-fibre separators to deliver steady service over long discharge periods rather than only short bursts. Gas recombination recovers over 90 percent of generated gas during normal float operation, reducing internal pressure buildup. Expected floating service life spans four to seven years depending on temperature and depth of discharge. Sealed construction prevents electrolyte leakage in any mounting orientation.

Interface and safety limits

Each battery is classified as non-spillable and meets International Air Transport Association requirements for transport. The sealed case allows operation in any position without leakage from terminals or housing. No provision exists for adding water or measuring electrolyte density during service life. These constraints define the practical limits for deployment in mobile or remote installations.

Questions about this item

Does the 12 V 7.4 Ah AGM battery generate noticeable heat or noise during continuous float charging?

The sealed AGM construction recombines over 90 % of generated gas internally, so the battery runs silently and produces negligible heat under normal float operation.

What existing equipment is required to use these four 12 V 7.4 Ah units as a direct replacement?

They are 100 % OEM replacements for models such as pxl12072, lc-r127r2p1, wp7.2-12 and sh1228w, so any device designed for those part numbers will accept them without modification.

Will the 12 V 7.4 Ah AGM pack work reliably alongside older lead-acid batteries already in my UPS string?

Mixing batteries of different ages or chemistries is not recommended; for balanced performance and the stated 4-7 year service life, replace the entire string with this matched 4-pack.
