The MPL Power Elektro MWH 12V/9Ah uses VRLA (AGM) technology and is built for standby and cyclic duty in emergency power systems, UPS units, and automation controllers. Its sealed construction makes it maintenance-free and safe for use in enclosed equipment.

At 50% depth of discharge, the MWH series delivers up to 500 charge-discharge cycles — 25% more than the MWL series. With a designed service life of 6–9 years at 20–25°C, it suits medium-term installations where replacement access is limited.

Key Features

• VRLA (AGM) technology for maintenance-free operation
• Nominal voltage 12V with 9Ah nominal capacity
• Max discharge current 135A for 5 seconds
• Max charge current 2.7A
• Operating temperature range: -20°C to +50°C (discharge/charge/storage)
• Internal resistance 16mΩ on a fully charged battery

Product Benefits

• Up to 500 cycles at 50% discharge provides longer service in cyclic applications than standard lead types
• AGM technology immobilises the electrolyte, eliminating leakage risk in any orientation
• Standby charge voltage 13.50–13.80V keeps the battery float-charged without gassing
• Cyclic charge voltage 14.40–15.00V supports regular charge-discharge routines
• Designed service life of 6–9 years at 20–25°C suits medium-term infrastructure
