How to change the IC card water meter battery? How to change the battery of the water meter

It depends on whether the IC card water meter uses a 3V lithium battery or a lithium battery or a 6V or lithium battery, and determines the voltage.

Secondly, it depends on the battery model: CR123A, CR14505, CR17450, CR17505, CR18505, CR26500, etc.

Common models of lithium sub-batteries: ER14250M ER14335M ER14505M ER17335M ER18505M ER26500M, etc.;

If the two batteries are wrapped together, the battery model is: 6V lithium manganese battery pack: 2cr cr cr cr17505

Lithium sub-battery packs: 2ER14250M, 2ER14335M, 2ER14505M, 2ER17335M

Then it depends on whether the battery is a cable or a plug on the line, if the battery with a wire, use a soldering iron to solder the positive red wire of the battery** on the wiring board of the road board, the black wire or other colored wires are usually the negative pole of the battery, and the wire is soldered at the negative terminal connection. It is best to have a plug, but it must be equipped with a plug with the same spacing as the original model, and the position of the red and black wires must be the same, otherwise it will short circuit and damage the circuit. If your battery only has two wires or the plug model is different, there is no soldering iron.

There are also ways. Finally, you can cut off the original old battery plug, red to red, black to black to connect the wire core, and wrap it separately. Install the battery, swipe the water purchase card, the solenoid valve will open, and your water will be ready to use.

IC card water meters are used in the special lithium battery, and generally must open the shell or the battery cover plate on the shell (but must open the front seal), so you still find a water company to replace it, now there are dual power supply, you can directly replace the external 4 No. 5 batteries.

IC card water meter is replaced with lithium batteries, it is best to contact the manufacturer to replace, about 20 yuan to change, on the market to buy your own may not be able to use!

First, prepare a water meter.

Second, then use a paper cutter to pry out the round cover along the edge.

3. Then open it with a slotted screwdriver, and you can see the battery.

4. Then take out the old battery and unplug it.

5. Replace it with a new battery.

6. After changing the battery, plug in the card again, if it can't be read, unplug the battery, and then install it and try several times, so that the replacement of the water meter battery is completed.

To find the battery compartment and take out the battery, buy the same type of lithium battery, the auxiliary style is basically the same as easy to install, some wiring, some batteries with plugs, just plug it in.

Now most of the battery replacement is the manufacturer, and the manufacturer is killing people too expensive, which is a commodity long breaking behavior.

How to replace the battery of the water meter.

The water meter is driven by pressure, and there is no need to change the battery.

Are you talking about a water meter or a waterproof watch? If the water meter doesn't have a battery, you don't need to change the watch, so you have to get the maintenance person to change it.

Hello dear, I'm glad to answer for you! 1. Cut open the lead seal of the battery compartment, remove the screws that fix the hatch cover, and take out the battery. The battery compartment is on the underside of the water meter.

2. Press the buckle, unplug the joint, and disconnect the battery buckle. The water meter uses two 3V lithium batteries, the model is CR14505E, and the battery is connected to the water meter by a buckle. 3. The battery can be bought from **, search for "CR14505E", ** is about 30-40 yuan.

4. After buying the new battery, pay attention to whether the positive and negative electrodes are the same as the original battery, mainly depending on the connecting wire. If it is correct, plug the buckle with the water meter buckle.

2. Press the buckle, unplug the joint, and disconnect the battery buckle. The water meter uses two 3V lithium batteries, the model is CR14505E, and the battery is connected to the water meter by a buckle. 3. The battery can be bought from **, search for "CR14505E", ** is about 30-40 yuan.

4. After the new battery is bought, pay attention to whether the positive and negative electrodes of the dust destroyer are the same as the original battery, mainly depending on the connecting cable. If it is correct, plug the buckle with the water meter buckle.

How to replace the water meter battery:Tools: smart water meter, flathead screwdriver, battery.

1. Find the battery compartment on the side of the smart water meter, and if there is a shield on it, tear it off directly.

2. Remove the battery compartment cover with a flathead screwdriver, and then you can take out the battery.

3. Unplug the plug and wire on it, so that the battery can be removed separately.

4. Prepare the same type of battery, connect the wire, and then plug in the plug to complete the replacement.

The maintenance method of smart water meter is as follows:1. When the smart water meter has been used for a long time, it will be contaminated with too much dust on its surface, if it is not cleaned in time, it is easy to accumulate more and more dust, and it is very troublesome to clean it after the dust is very strong. In serious cases, it may also directly lead to the error of the meter degree.

2. In the process of using smart water meters, regular maintenance is also indispensable. When the surface of the water meter is stained with acid and alkali stains, it needs to be wiped clean in time, otherwise the acid and alkali substances are very likely to cause the water meter to be corroded. Of course, the meter also needs to be protected from moisture, otherwise there will be wrong readings, so wipe it dry if there is any water stain.

3. Smart water meters are installed on water pipes, so whether it is for the good of smart water meters or water pipes, heavy objects cannot be placed on the water meter, otherwise it will lead to rock excavation and cause damage. If there is an adverse reaction to the smart water meter in Tusanshan, do not disassemble and assemble it at will, but contact the after-sales personnel to be responsible.

Behind the plugged card water meter is the battery box, cut off the lead seal behind the battery box, you will see the white plug connected to the battery and the water meter, buy a new battery, and replace it.

1. Cut off the lead seal of the battery box and take out the battery.

2. The white plug connects the battery to the water meter.

4. Just put it on.

Precautions

If the smart water meter is out of power, it is generally recommended to ask the property or water plant staff to replace it, and it is best not to replace the battery yourself.

If the voltage is low or the power is insufficient, the water meter valve will automatically close and stop the water.

This kind of water meter generally uses a special lithium battery for the meter, which is not sold in general places, and if the property (water company) has a spare battery or a spare meter, it can be replaced nearby.

It is not recommended to replace the battery privately, first, the battery is not easy to find, but the water meter has a lead seal, and it is not allowed to be opened without permission.

Plug in the card water meter, generally there is a battery compartment on the back of the meter, open it to see what model it is, whether it is plugged in or welded, buy it according to the model, and install it.

Hello, dear, I am happy to answer for you: smart IC card water meter battery replacement steps, community water meter model: Wuhan Shengfan Electronics Co., Ltd., SVIL IC card smart cold water meter, original battery and illustration model:

Lithium battery. Take out the original water meter battery steps: there is a round cover on the water meter, you need to pry it out along the edge with a blade, after opening it is a large Phillips screw, open it with a slotted screwdriver to see that there are circular covers on both sides of the battery meter, there is a side of the convenient to take out the battery and plug wire, take out the battery, unplug it, replace it with a new battery, and then plug in the hole in the card to see if it can be read normally.

If you can't read it, unplug the battery, install it and try it a few more times, first confirm the plug interface of the self-selling Qingjia water meter, and then go to buy it online.
