Upgrade Kit for MBP-1207 Battery

Part # MBP-1308-KIT

Replaces NSN 6140-01-393-9041

Peak Beam Systems, Inc. discontinued all MBP-1207 NiCad Batteries and Chargers in August 2016.

The replacement for the obsolete MBP-1207 NiCad Battery System is the Lithium Iron Phosphate (LiFePO4) Battery System.  LiFePO4 Batteries are compatible with all older Maxa Beam Searchlights and offer several significant advantages over the discontinued NiCad Battery Systems.

Advantages of the Replacement LiFePO4 Battery System include:

  • Longer Run Time (115 minutes vs. 90 minutes on default beam level)
  • Faster Recharge Time (110 minutes vs. 150 minutes)
  • More Life Cycles (>2000 vs. 1000)
  • Lighter Weight (3.5 lbs. vs. 5.5 lbs.)
  • Lower Cost

Peak Beam Systems will continue to provide phone and email technical support for NiCad Battery Systems indefinitely, but spare parts are no longer available.  Peak Beam Customer Support recommends replacing any non-functional NiCad Battery or Charger with a complete new LiFePO4 Battery System.

    Battery Storage and Transport:

    Always disconnect battery from the searchlight before storing or transporting.  If storing battery for long periods of time, store battery at 75% charge level and recharge once every six months.  Do not store batteries above 60°C (140°F) or below -20°C (-4°F).  Store in a cool, dry location not subject to frequent temperature fluctuations.  Elevated temperatures can result in reduced battery service life.

    All Lithium Ion batteries are classified as Class 9 Dangerous Goods for air, sea and surface transport and must be packaged and transported according to applicable regulations.  However, small, “excepted” batteries such as the MBP-1308 LiFePO4 Battery are not subject to certain provisions of the regulations (e.g. Class 9 labeling and UN specification packaging).

    • Batteries shipped within the United States via ground transport methods must be packed, marked and labeled in accordance with the exceptions for small lithium batteries per 49 CFR 173.185(c).
    • Batteries shipped via air transport methods without searchlights are classified as UN3480 Lithium ion batteries and must be packed, marked and labeled in accordance with Sec II or Sec IB of IATA/ICAO PI 965 – Cargo Aircraft Only.
    • Batteries shipped via air transport methods with searchlights are classified as UN3481 Lithium ion batteries packed with equipment and must be packed, marked and labeled in accordance with Sec II of IATA/ICAO PI 966.
