Handling of Li-ion Battery

Restriction on Usage

Restriction on Usage Environment

The recommendation temperature range for use of the Lithium-ion is as follows,
- Charge: 0~40℃
- Discharge: -20~60℃
- Storage: -20~50℃
Do not use or store a battery at high temperature, such as in strong direct sunlight, in cars under hot weather, or directly in front of heaters. This may cause battery fluid leakage, impaired performance, and shortening of battery service life.
Do not charge a battery when it is cold (below 0℃), or outdoors at cold temperature (below 0℃). This may cause impaired performance and shortening of battery service life.
Do not splash fresh or saltwater on a battery, or allow the terminals to become damp. This may cause heat generation and formation of rust on the battery and its terminals.

Restriction on Condition of Use

Do not connect different assembled batteries together. This may cause electrical shocks, fluid leakage, heat generation, bursting, or fire. And also do not connect same assembled batteries in series. This may also cause electrical shocks, fluid leakage, heat generation, bursting, or fire.

Preparation before Use

Do not Connect Batteries to a Power Source

The Lithium-ion battery has + (positive) and - (negative) terminals. If a battery does not work when connected to a charger or device, do not attempt to force the connection. Verify the accuracy of + and - terminals. Charging the battery with the terminals reversed may drain rather than charge the battery, or cause abnormal chemical reaction in side the battery, abnormal current flow during discharge, fluid leakage, heat generation, bursting or fire.
Do not connect a Lithium-ion battery directly to a power outlet or insert it into a cigarette lighter socket in a car. High voltage may cause fluid leakage, heat generation, bursting or fire.

Methods of Use

Operation

Do not use the Lithium-ion batteries together with other batteries of different type, brand name or capacity. That may cause leakage of battery fluid, heat generation, bursting or fire.

Do Not Misuse Batteries

Do not dispose Lithium-ion batteries in fire or heat. Doing so may melt the insulation, damage the sealing parts or protective devices, cause leakage of battery fluid (electrolyte) from the batteries, bursting or fire.
Do not connect the + (positive) and - (negative) terminals of Lithium-ion batteries with a wire or electrically conductive materials. Do not carry or store Li-ion batteries together with metal necklaces, hairpins, or other electrically conductive materials. Doing so may short circuit the battery, which could result in excessive current flow and possibly cause leakage of battery fluid, heat generation, bursting or fire. When carrying or storing batteries, use an electrically nonconductive (insulated) case.
Do not solder a lead wire or plate directly to Lithium-ion batteries. The heat generated by the soldering may melt the insulation, damage the sealing parts or protective devices, cause leakage of battery fluid, heat generation, bursting or fire.
Do not charge or use Lithium-ion batteries with the + (positive) and - (negative) terminals reversed. Charging the battery with the terminals reversed may drain rather than charge the batteries, or cause abnormal chemical reaction inside, abnormal current flow during discharge, leakage of battery fluid, heat generation, bursting or fire.
Do not connect a Li-ion battery directly to a power outlet or insert it into a car cigarette lighter socket. High voltage may cause excessive current flow, leakage of battery fluid, heat generation, bursting or fire.
Do not break open the casing of a battery or damage it. Doing so will expose the battery to the risk of a short circuit, and may cause leakage of battery fluid, heat generation, bursting or fire.
Do not strike or drop Lithium-ion batteries. A sharp impact can cause leakage of battery fluid, heat generation, bursting or fire.
Do not connect two Lithium-ion batteries in series as this may cause leakage of battery fluid, heat generation, bursting or fire.
Do not transport Lithium-ion batteries by holding onto the connectors or lead wires, as this may damage the batteries.

Do not Use Continuously for Periods Longer than the Rated Time or with Loads Exceeding the Rated Load

Do not overcharge Lithium-ion batteries exceeding the predetermined charging period specified in the charger's instruction manuals. Also, do not recharge a battery fully charged. This may cause leakage of battery fluid, heat generation, bursting or fire. It could also deteriorate the performance or cycle life.

When Batteries Are Not in Use

Be sure to turn off the equipment or the device after using Lithium-ion batteries. Failure to do so may cause leakage of battery fluid.

During non-use, do not leave the Lithium-ion battery connected to the equipment or the device for a long time. To prevent leakage of battery fluid and corrosion (rust) during the period when the Li-ion is not being used, remove the battery from the equipment or the device and store it in a place at low humidity and temperature of -20 to +30℃. Batteries that have not been used for a long time may not be fully charged.

Maintenance and Inspection

Totex Recommends Periodic Inspections

Lithium-ion batteries have a predetermined operating life. If the operating time shortens excessively, this means that the battery life has expired. If it comes to that point, stop use immediately and replace with new batteries.

Inspection and Cleaning (including label on unit)

If the Lithium-ion battery terminals are dirty, clean them with a soft, dry cloth prior to use. These terminal dirt causes loose contact with the equipment or the device, loss of power, or inability to charge.

Countermeasures

Do Not Use Defective or Abnormal Battery

If Lithium-ion batteries are not fully charged after the battery charger's predetermined charging period has elapsed, stop the charging process. Prolonged charging may cause leakage of battery fluid, heat generation, or bursting.

If Lithium-ion batteries leak electrolyte, change color, change shape, or change in any other way, do not use them. Usage may cause heat generation, bursting or fire.

Emergency Measures

If leaked electrolyte comes in contact with the eyes, flush the eyes immediately, washing them thoroughly with clean water from a tap or other source, and consult a doctor. Leaked electrolyte can damage the eyes and lead to permanent loss of eyesight.

If skin or clothing comes in contact with leaked electrolyte, wash this area immediately with clean water from a tap or other source. Leaked electrolyte can cause skin damage.
