What is the battery of the air conditioner remote control

Under normal circumstances, home appliance remote controls use AAA batteries, while cameras, shavers, and wall clocks use AAA batteries. Therefore, the air conditioner remote control is also a AAA battery. If we are not sure, we can determine it by measuring the diameter and length of the battery. No. 7 battery is 43.6 mm high and 10.1 mm in diameter, while No. 5 battery is 14 mm in diameter and 49 mm in height.

3.Test Method

	Item	Condition
1	Dimensions	When measure with vernier calipers which precision is up 0.02mm. to avoid short circuit, should paste on one insulation material on one end of the vernier calipers.
2	Open voltage	the precision of multimeter is not lower than 0.25%, intel resistance is bigger than 1MΩ
3	Instant short-circuit current	When test with multimeters, not surpass 0.5 second each time, avoid duplicating tests, if need once more, the time-gap should above half hour
4	Appearance	Appearance of batteries shall be inspected by visual means.
5	Min time of discharge	Lay aside above 8 hours in the temperature of 20±2℃ and under the humidity of 60±15% conditions, with the condition that Resistance is 15kΩ, end-point voltage is 2.0V. The new battery (Initial stage) should be tested in 60 days after produce. The old battery (Delayed for 12 months) should be tested in 14 days after the storage period.
6	Over-discharge Characteristics	Take nine battery in the temperature of 20±2℃ and under the humidity of 60±15% conditions, with the condition that Resistance is 15kΩ, end-point voltage is 1.2V. visual test.

4.Acceptance rule

4.1 Delivery inspection for each shipment quantity for a test batch。

4.2 Delivery inspection using GB2828.1-2003 Normal inspection sampling plan at a time，inspection item、inspection level（IL）、acceptance quality limit（AQL）According to the provisions of the table below。

	Check item	IL	AQL
1	Dimensions	I	0.25

3	Appearance	Ⅱ	0.25

5.Important Notes（Warranty）

5.1No swallowing

Keep the battery out of reach of children. Never put batteries in mouth. If ingested, immediately seek medical attention.

5.2No recharging

Forbid using any other power supply to charge the battery. Recharging can lead to produce gas and internal short circuit, causing cell deformation, leakage, overheat, explode or catch fire.

5.3Do Not Dispose In Fire

The lithium will be melted when dispose in fire.

5.4Do Not Disassemble

Do not disassemble the battery or it will cause the damage of gasket or the separator, deformation, leakage, over-heat, explosion or firing will happen.

5.5Insert Batteries Correctly

Depending on the application device, incorrect insertion of batteries, with positive(+) and negative(-) poles reversed, may result in short circuits and the risk of heat generation, fire or explosion.

5.6Do Not Short-circuit

Do Not Short-circuit. Do not keep or store the battery with metal or it will cause deformation, leakage, over-heat, explosion or firing.

Do not take several pieces of batteries from the packing box at one time or stock mixed, it can lead deformation, leakage, over-heat or firing.

5.7Do Not Mix Different Types Of Batteries

For some application, mixing different types of batteries, or new and old batteries, can cause over discharge due to difference in voltage and electrical capacities. This may lead to the risk of swelling or explosion.

5.8Do Not Weld Pin Or Wire Directly On The Battery

The lithium will melt when welding or cause damage of insulation material. This will lead deformation, over-heat, explosion or firing. If weld is needed, please contact Daily-max or professional welder.

6.Cautions

6.1Shaking、jumbling、Scatters or trampled batteries, may cause short circuits, heat generation, fire or explosion.

6.2 Install batteries, please be careful when operating, don't let the battery come into contact with metal objects could make the battery short circuit.

6.3Selecting suitable batteries as the operation instructions.

6.4Do not use or store the batteries in high-temp places like exposure sunshine or in car which in burning hot, it will lead deformation, leakage, over-heat, explosion or firing.

6.5Do not let the battery contact water or store in a wet environment or it will cause rust, deformation, leakage, over-heat, explosion or firing.

6.6The voltage may lower than target one by bad contact so pls keep 2N contact pressure.

6.7If any questions please contact Anyida.

7.Storage Environment

The storage environment should be clean, cool, dry, ventilation, do not close to high-temp or high moisture, the environment temp should 0℃-30℃, RH not exceed 75%.

8.Marking and Packing

8.1Sign Of Positive Pole
