Victron Energy Lead-Carbon 12V 160Ah (M8) Battery BAT612116081

The Victron Energy Lead-Carbon Battery BAT612116081 is a 12V VRLA battery designed for applications involving frequent cycling and partial state-of-charge operation. Victron's lead-carbon technology uses a lead-carbon composite in the negative plate to help reduce sulfation and improve charge acceptance compared with conventional flat-plate VRLA lead-acid battery construction. 

This model provides a rated capacity of 160Ah at the C20 rate, with additional capacity ratings of 150Ah at C10 and 138Ah at C5. Victron specifies at least 500 cycles at 100% depth of discharge, at least 1,000 cycles at 60% depth of discharge, and at least 1,400 cycles at 40% depth of discharge under the manufacturer's stated test conditions.

Key Technology

• Lead-Carbon Battery Technology
  The negative plate incorporates a lead-carbon composite designed to reduce sulfation and improve charge acceptance during demanding cycling applications.

• 160Ah C20 Capacity
  Provides a rated capacity of 160Ah at the C20 discharge rate to the manufacturer's specified 10.8V endpoint.

• Improved Partial State-of-Charge Performance
  Lead-carbon construction helps reduce negative-plate sulfation when the battery spends extended periods at partial state of charge.

• Enhanced Cycle Life
  Victron specifies at least 500 cycles at 100% DoD, at least 1,000 cycles at 60% DoD, and at least 1,400 cycles at 40% DoD under the specified test conditions.

• Improved Charge Acceptance
  The lead-carbon composite is designed to improve charge acceptance at the negative plate, supporting applications where regular cycling and recharge performance are important.

• Lower Charge Voltage
  Victron identifies lower charging voltage as an advantage of lead-carbon technology, contributing to higher efficiency and reduced corrosion of the positive plate.

• VRLA Construction
  Combines valve-regulated lead-acid battery construction with lead-carbon negative-plate technology intended to address common cycling limitations such as sulfation.

• M8 Insert Terminals
  Uses M8 insert terminals for secure electrical connections in properly designed battery systems.

Best Uses

• Solar Energy Storage
  Suitable for compatible solar battery systems that experience regular charging and discharging cycles.

• Off-Grid Battery Systems
  Well suited to battery-based power systems where repeated cycling and periods of partial state of charge are common.

• Backup Power Systems
  Suitable for compatible backup and standby applications requiring a rechargeable 12V lead-carbon battery.

• Marine Battery Systems
  Can be incorporated into properly designed marine electrical systems requiring compatible lead-carbon energy storage.

• RV & Mobile Power Systems
  Suitable for compatible mobile energy-storage applications where battery banks undergo regular charging and discharging.

• Partial State-of-Charge Applications
  Particularly useful in applications where the battery may operate for extended periods without immediately receiving a complete recharge.
