We only use cells listed with UL standards entities. QUALITY AND ENVIRONMENTAL MANAGEMENT SYSTEMS (ISO Certified) ISO 9001:2008 Quality Management System ISO 14001:2004 Environmental Management System IEC/UL 62133IEC62133 certifications and additional laboratory services are available as required by our OEM clients.

Abyss Battery®, Inc manufacturing process is compliant and licensed on a 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.

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.
