PI-72-04 EnerChip Standards Compliance
• Tests for Technician-Replaceable and User-Replaceable Batteries Sections 10-20. Even though
EnerChip batteries are not within the scope of UL 1642, the tests described in this document should be
understood and EnerChip batteries should pass these criteria for safe operation :
• 10 - Short Circuit Test - The battery is to discharge until a fire or explosion is obtained, or until it has
reached a completely discharged state of less than 0.1 volts. The EnerChip will not catch on fire and
will reach a state of less than 0.1 volts in the presence of a short circuit.
• 11 - Abnormal Charging Test - The battery is to be subjected to a charging current of three times the
current specified by Cymbet for a minimum of 7 hours without catching fire. The highest amount
of charging current used for a particular EnerChip device is 4 times the energy storage capacity
of a device. For example this would be 200 microamperes for a CBC050. Therefore for this test
600 microamperes would be supplied to an EnerChip CBC050 for 7 hours. When this is done, the
EnerChip does not catch on fire.
• 12 - Forced Discharge Test - this test is intended for cells that are to be used in series-connected
multi-cell applications. EnerChips are typically connected together for increased capacity, but could
be connected in series for increased voltage. A completely discharged cell is to force-charged by
connecting it in series with fully charged cells of the same kind and not explode or catch on fire when
done so. EnerChips do not explode or catch on fire.
• 13 Crush Test- A battery is to be crushed between two flat surfaces and not explode or catch fire.
EnerChips when crushed do not explode or catch fire.
• 14 - Impact test - A test sample battery is to be placed on a flat surface and struck with a 20 pound
bar is to be dropped 24 inches onto the device and not explode or catch fire. EnerChip batteries when
impacted do not explode or catch fire.
• 15 - Shock Test - a cell is to be subjected to 3 shocks where the shock to the cell is be accelerated
such that the during the initial 3 milliseconds the minimum average acceleration is 75g with no
explosion or fire. EnerChips do not explode or catch fire.
• 16 - Vibration Test - A battery is to be subjected to simple harmonic motion with an amplitude of
0.8mm with varying frequency between 10 and 55 Hz over 90 minutes tested in three mutually
perpendicular directions and not explode, catch fire, vent or leak. EnerChip batteries do not explode,
catch fire, vent or leak.
• 17 Heating Test - A battery is to be heated from a temperature of 20 degrees C to a temperature of
130 degrees C and remain for 10 minutes at that temperature and then cool down to 20 degrees C
without exploding or catch fire. EnerChip batteries do not explode or catch fire.
• 18 - Temperature Cycling - Repeating 9 temperature variation cycles from 70 to 20 to 40 to 20
degrees C and not explode, catch fire, vent or leak. EnerChip batteries do not explode, catch fire, vent
or leak.
• 19 - Low Pressure (Altitude Simulation) Test - Sample batteries are stored for 6 hours at an absolute
pressure of 1.68 psi and temperature of 20 degrees C and not explode, catch fire, vent or leak.
EnerChip batteries do not explode, catch fire, vent or leak.
• 20 - Projectile Test - When a cell is subjected to a fire heated screen until it explodes, no part of
an exploding cell shall penetrate a wire screen. EnerChips do not explode under these heating
conditions and would not project cell debris through this wire screen.
• Marking Guidelines - EnerChips also comply with the device marking requirements:
• Cymbet’s trade name appears on the device
• A distinctive model number identification is marked
• A dating period of manufacture is marked
