    UN/DOT 38.3: Lithium Battery Transportation

    All Abyss Battery®, Inc. Lithium Batteries are required to pass section 38.3 of the UN Manual of Tests and Criteria, to ensure the safety of using products for our end users and for shipping purposes. We are proud of our investment to ensure our products have been UN38.3 certified.

    T1 – Altitude Simulation
    This is low pressure testing that simulates unpressurized airplane space (cargo area) at 15,000 meter altitude. After storing batteries at 11.6kPa for >6 hours, these criteria shall be met: no mass loss, leaking, venting, disassembly, rupture or fire, and voltage within 10% of pre-test voltage.

    T2 – Thermal Test
    This test covers changes in temperature extremes from -40°C to +75°C.  Batteries are stored for 6 hours at -40°C (12 hours for large cells/batteries), then 6 hours at +75°C (12 hours for large cells/batteries), for a total of 10 cycles. Testing may be performed in a single chamber or thermal shock chamber, but less than 30-minute transitions shall be used. 

    T3 – Vibration
    This test simulates vibration during transportation.  Test is a Sine Sweep: 7Hz – 200Hz – 7Hz in 15 Minutes; 12 Sweeps (3 hours); 3 mutually perpendicular axes. 

    T4 – Shock
    This test also simulates vibration during transportation.  Test is a Half-Sine pulse: 150G/6ms for small cells/batteries; 50G/11ms for large cells/batteries; 3 pulses per direction; 6 directions (+/-z, +/-x, +/-y).  Same pass criteria as T1.

    T5 – External Short Circuit
    This test simulates an external short to the terminals of the cell or battery. At temperature of +55°C, apply short circuit (<0.1ohm) across terminals.  Maintain at least an hour after sample temperature returns to +55 +/-2°C.  Pass criteria are: Case temperature does not exceed +170°C and no disassembly, rupture, or fire within 6 hours of test.  Fuse, current limiting circuit, and venting mechanism activation are allowable.

    T6 – Impact
    This test is only applicable to primary and secondary cells.  For cylindrical cells >20mm diameter, it simulates impact to case of cell. For cylindrical cells <20mm diameter and all other cell constructions, it simulates crushing of a cell. Pass criteria for any type is: Case temperature does not exceed +170°C & no disassembly or fire within 6 hours of test.

    T7 – Overcharge
    This test is for secondary or rechargeable batteries only.  It simulates an overcharge condition on a rechargeable battery: 2x the manufacturer’s recommended charge current for 24 hours.  Then battery shall be monitored for 7 days for fire or disassembly.

    T8 – Forced Discharge
    This testing simulates a forced discharge condition for primary and secondary cells only.

    Very excited to charge my AGMs and Lithium batteries

    This charger was a larger profile than the 4 bank Minn Kota that I was replacing. I had to relocate it, but that worked to my advantage. It is now easier to see the charge status. I connected to the batteries before changing the profiles. it defaults to lithium. I pulled the fuses from the AGM connections, changed the charging profiles, reconnected the fuses and -- ALL GOOD.
