12V 4.5Ah SLA Battery DP4.5-12 VRLA AGM Rechargeable Sealed Lead Acid

Standby Battery for UPS and Alarm Panels

The 12V 4.5Ah SLA Battery is a sealed valve-regulated lead acid block for standby and cyclic duty. The DP4.5-12 case measures 90 x 70 x 101 mm and weighs roughly 1.5 kg. Absorbent glass mat separators hold the electrolyte, so the unit installs in any orientation except inverted.

Six series cells deliver 12V nominal with a 4.5Ah capacity at the 20-hour rate. The battery accepts a float charge of 13.5 to 13.8V and a cycle charge of 14.4 to 14.7V. Internal resistance sits near 40 milliohms on a fresh block, which supports short high-current bursts for alarm sounders and door strikes.

F1 spade terminals measure 4.8 mm and seat in standard crimp receptacles. The case uses flame-retardant ABS and vents through a one-way pressure relief valve. Self-discharge holds under 3% per month at 25°C, so stock rotates on a 6 to 12 month cycle. Design life reaches 5 years at 20°C under float conditions.

Key Features

• Absorbent Glass Mat Construction
  Glass microfibre separators immobilise the electrolyte and allow spill-free operation in any cabinet position.

• Sealed VRLA Design

  • One-way relief valve vents excess pressure
  • No water topping required through service life
  • Low gassing supports use inside occupied rooms

• 4.5Ah Capacity at 20-Hour Rate
  The rated capacity covers long standby holds in alarm and access control panels.

• F1 Spade Terminals
  4.8 mm tabs accept standard female crimp connectors without adapters.

• Low Self-Discharge
  The block loses under 3% capacity per month at 25°C, which suits buffer stock.

• Flame-Retardant ABS Case
  The housing resists ignition and maintains shape if a cell vents.

• Rechargeable Chemistry
  The block accepts repeated charge and discharge cycles under a suitable charger.
