The MPL Power Elektro MWS3.4-12 is a sealed, maintenance-free lead-acid battery built in VRLA (AGM) technology. It is designed primarily for use in control panel charging systems and also serves as a backup power source in portable devices. The rated service life is 3–5 years when stored or operated at 20–25°C.

Its compact 13.4×6.7×6 cm footprint allows it to fit into confined enclosures typical of alarm panels, UPS units, and automation cabinets. The battery supports both standby and cyclic charging modes.

Key Features

• VRLA (AGM) sealed construction — maintenance-free, no acid spillage risk
• 12V nominal voltage with 3.4Ah nominal capacity
• Dual charging mode support: standby use (13.50–13.80V) and cyclic use (14.40–15.00V)
• Max. discharge current of 35A for 5 seconds for high-demand surge loads
• Internal resistance of 46 mΩ when fully charged

Product Benefits

• Sealed AGM design eliminates topping-up and reduces maintenance effort
• Wide operating temperature range (-20°C to 50°C) covers both indoor and unheated enclosure installations
• Low max. charge current (0.95A) allows safe charging from low-power charger outputs
• Compact dimensions make it compatible with most standard alarm and UPS battery bays
• Rated 3–5 year service life at 20–25°C gives predictable replacement cycles
