Lithium ion do's and don'ts
- To avoid damage to the battery pack, make sure that the battery pack is positioned away from heat sources in the equipment or in the battery charger.
- Be sure to use a battery pack lock mechanism to prevent the battery pack from being ejected when the equipment is dropped or receives a sudden impact.
- Use a terminal structure that makes it unlikely that the terminals will be shorted by metallic necklaces, clips, hairpins, etc. Structure the battery and the terminals to the battery in such a way that the battery pack cannot be put in backwards when installed in the charger or the equipment.
- If the battery is built into other equipment, use caution to strictly avoid designing airtight battery compartments.
- Use materials that are highly resistant to corrosion (such as nickel or nickel-coated copper). If contact resistance is an issue, we recommend that you use contact plating (such as gold plating) on the terminals.
- The batteries should be stored at room temperature, charged to about 30 to 50% of capacity. We recommend that batteries be charged about once per year to prevent over discharge.
- See the section on “Safety Precautions for the Lithium Ion Battery Pack.”
- Because batteries utilize a chemical reaction, battery performance will deteriorate over time even if stored for a long period of time without being used. In addition, if the various usage conditions such as charge, discharge, ambient temperature, etc. are not maintained within the specified ranges the life expectancy of the battery may be shortened or the device in which the battery is used may be damaged by electrolyte leakage. If the batteries cannot maintain a charge for long periods of time, even when they are charged correctly, this may indicate it is time to change the battery.
- The performance and life expectancy of batteries depends heavily on how the batteries are used. In order to insure safety, be sure to consult with us in advance regarding battery charging and discharging specifications and equipment structures when designing
