Routine Maintenance; Transportation - Tecate TPLC Series User Manual

Our recommendations for appropriate cell mounting and spacing are as follows:
Please contact the engineering team at the Tecate Group for more information,
(eng@tecategroup.com) on cell mounting and spacing. Using the Hybrid Capacitor could
generate heat and should be used within the currents specified on the data sheets. When
an application requires multiple cells in combination, care must be taken to maintain
equalized voltages and use of an equalization circuit is recommended. We always
recommend that extreme care should be taken when Hybrid Capacitors are used in
combination, whether for series or parallel connections as these are already charged cells
and ensuring proper voltage integrity is essential. Many applications do require the leads
to be cut or bent for assembly onto a PCB. Do exercise caution and cut and/or bend each
lead separately to prevent electrical shorts. Do not bend or cut the leads without a proper
fixture to eliminate additional stress on the body of the cell or terminals. Specific
recommendations for bending or cutting leads may be discussed with Tecate Group
engineering (eng@tecategroup.com).
6. Routine Maintenance: It is recommended that the state of charge of cells in storage should
take place annually to ensure cell voltage does not dwell below 2.2VDC while in storage.
Any cell found to be below or close to the 2.2VDC threshold should be charged using a
power supply to 3.8VDC.
7. Transportation: When transporting the cells be mindful of the following:
 Avoid excessive shock and vibration
 Sturdy packaging to prevent damage from stacking
 Isolation of the individual terminals to avoid a short circuit
 Do not drop or pierce the packaging
 Ensure the product is dry, free from condensation and excessive humidity
 Voltage should be measured to verify it is within specification before and after
shipment
Hybrid Capacitors with an energy density less than 0.3Wh are not restricted as dangerous
goods according to IATA or 49 CFR § 172 regulations. However, as transportation regulations
may be modified it is best to check local regulations for any updates regarding new mandated
