SKU CH-YYJM-V4JTY

12 V 2.3 Ah sealed lead-acid battery replaces dmu12-3 vec158 with maintenance-free AGM design

  • 12 V 2.3 Ah capacity powers compatible devices reliably
  • Advanced AGM technology delivers maintenance-free sealed operation
  • 100 % OEM replacement fits dmu12-3 vec158 directly
  • Expected service life of 4 to 7 years
  • Three-year warranty covers UPS and backup applications

Direct Replacement Fit

This 12V 2.3AH sealed lead acid battery is an exact 100% OEM replacement for the dmu12-3 vec158 unit. It serves owners of UPS systems, backup devices or power tools who need a drop-in cell without wiring changes. The advanced AGM technology keeps the pack maintenance free and ready for standby or cyclic use.

Rugged Valve Regulated Build

PowerStar valve regulated construction seals the electrolyte so the battery can be mounted in any orientation without leaks. The rugged case resists vibration in portable tools and stays stable on a UPS shelf. Maintenance free operation means no water topping or acid checks are required during the expected 4-7 year service life.

Upgrade From Worn Cells

The battery replaces ageing SLA packs that no longer hold a full charge or that show swelling and high internal resistance. A swap is worth it when runtime has dropped below useful levels or when a UPS self test fails. Warranty coverage runs three years on UPS and backup devices and two years on other applications.
