Uniform internal heating is an important feature of our cold-weather performance batteries, as many external heating blanket options currently available cannot sense the internal temperature of the cells and may not be completely effective at heating the battery throughout. The system features proprietary technology that draws power from the charger itself, requiring no additional components. The entire process of heating and charging is completely seamless. Simply plug the battery into the regular lithium charger and the internal heating and monitoring system takes care of the rest.

Abyss Battery®, Inc manufacturing process is compliant and licensed on an international level by TÜV Rheinland for Functional Safety as a result of exposure to harsh marine environments such as vibration, impact, ignition protection, water ingress, and salt spray corrosion common on pleasure craft and boats. TÜV Rheinland stands for safety and quality in virtually all areas of business and life. TÜV Rheinland’s highly qualified experts test technical systems and products around the world, support innovations in technology and business, train people in numerous professions and certify management systems according to international standards. In doing so, the independent experts generate trust in products as well as processes across global value-adding chains and the flow of commodities. Since 2006, TÜV Rheinland has been a member of the United Nations Global Compact to promote sustainability and combat corruption.

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 a 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.  The 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 a temperature of 55°C, apply short circuit (<0.1ohm) across terminals.  Maintain at least an hour after the 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 the 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 in diameter, it simulates impact to the case of the cell. For cylindrical cells <20mm in diameter and all other cell constructions, it simulates the crushing of a cell. Pass criteria for any type are: Case temperature does not exceed 170°C & no disassembly or fire within 6 hours of the 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.
