Testing.

Testing conditions

(1)Temperature and Humidity:

Unless particularly specified, tests shall be conducted at the temperature (20±2℃) and the humidity (45%-75%RH).

(2) Storage of test specimen batteries:

Specimen batteries to be tested shall be kept at the ambient temperature (23±5℃) and the relative humidity (45%-75%RH).

Measuring instruments and devices:

(1) Dimension

The accuracy of Verniers are specified in 0.02mm, and micrometers or gauges specified in 0.01mm, or those having equal or better accuracy shall be used.

(2) DC Voltmeters:

The accuracy of voltmeters shall be 0.25% (max.) and the input resistance rating shall be 1MÙ or more.

(3) Load Resistance:

Load resistance shall include all resistance throughout external circuits, and its tolerance shall be 0.5% or less.

Test Methods.

(1) Appearance:

Appearance of batteries shall be inspected by visual means.

(2) Dimensions:

Dimensions shall be measured with instruments specified in Subparagraph 4.2(1), and the measuring end one or both shall be insulated when measuring the overall height of the batteries.

Open-Circuit Voltage:Tested specimen batteries shall be kept for 4 hours or longer at the ambient temperature specified in [Table 1], and then the voltage between both terminals shall be measured at the same ambient temperature with a voltmeter as specified in Subparagraph 4.2(2).

(3) Closed-Circuit Voltage:

Tested specimen batteries shall be kept for 4 hours or longer at the ambient temperature specified in [Table 1], and then the closed –circuit voltage between both terminals shall be measured with a voltmeter as specified in subparagraph 4.2(2) while the load resistance as specified in subparagraph 4.2(3) is connected between both terminals at the same ambient temperature as specified above; requiring that the reading measured value shall be taken for 0.8 seconds after the circuit is closed.

(4) Service Life:

Tested specimen batteries shall be kept for 4 hours or longer at the ambient temperature specified in [Table 2].and then shall be continuously discharged at the same ambient temperature and through the specified load resistance specified in Table 2. The discharge shall be continued until the voltage of the tested specimen falls below the end-point voltage of 2.0V, and the time from beginning to end point shall be taken as the service life.

(5) Service Life after High-Temperature Storage:

Tested specimen batteries, after having been stored at the temperature and through the period specified in [Table 3], shall be kept for 4 hours or longer at the ambient temperature (20 ± 2℃), and then shall be continuously discharged through the load resistance specified in [Table 3 ]at same temperature (20±2℃). The discharge shall be continued until the voltage falls below the end-point voltage of 2.0V, and the time from beginning to end point shall be taken as the service life after high-temperature storage.

Do not punch or hammer the batteries.

Do not connect the (+) and (-) terminals in reverse polarity to devices.

Do not mix use of different type or different series of batteries, nor used batteries with new ones.

Do not put a lead or spot weld directly on the battery, if requirement please contact with our sell-dept.

Do not expose the batteries to direct sunlight, hot and humid places.

Do not damage or mishandle the package of batteries. If package is damaged, the batteries must be quarantined, inspected, and repacked.

Optimum storage condition: temperature range 23±5℃、humidity range 45 % ~ 75 %

Please read this instruction carefully before use.

Warning.

Never recharge/short-circuit / disassemble. Never dispose in fire or expose close to a heat generating area.

To prevent to be swallowed by children accidentally, please keep them out of children in case that they are swallowed, contact with a physician immediately.

Never expose batteries to strong impact because there is the danger of combustion or burst. Be sure the battery disconnected from circuit when storing or disposing.
