Testing standards for marine batteries

　　Testing items:

　　The existence and durability of all parameters, some parameters, information and warning signs, appearance, high current tolerance, safety, capacity, sealing reaction efficiency, size, exhaust valve action, *, airtightness, short-circuit current and internal resistance, balance of terminal voltage, insulation resistance, tilt resistance, vibration resistance, sway resistance, overcharge resistance, charge retention ability, overcharge life, acid mist resistance, airtightness, short-circuit current and internal resistance level, balance of terminal voltage, balance of terminal voltage performance test, capacity performance test, short-circuit current and internal resistance test, overcharge resistance test, charge retention performance test, sealing reaction efficiency test, exhaust valve action test, overcharge life test, safety Performance test, acid mist resistance test, tilt resistance test, sway resistance test Vibration resistance test, existence and durability test of information and warning signs, short-circuit current and internal resistance test

　　Testing standards:

　　1. CB/T3821-2013 Lead acid batteries for ship communication and lighting

　　2. CB/T3821-2013 Lead acid batteries for ship communication and lighting CB/T3821-2013

　　3. CB/T3821-2013 Lead acid batteries for ship communication and lighting

　　Purpose of testing report

　　Supermarket entry, e-commerce listing, internal quality control, bidding, university research, etc.

　　Validity period of testing report

　　The general testing report will indicate the time when the laboratory received the sample and issued the report. The validity period will not be indicated on the testing report. Normally, as long as the test is not updated, the test remains unchanged and the detection report remains valid. If it has been used on e-commerce platforms, they generally only recognize products within one year. So it also depends on the platform or buyer's requirements.
