Instructions on how to replace the battery of water meter

In our family, we usually use a water meter to record our monthly tap water consumption. Now we all use smart water meters, which can clearly show the flow of tap water, which is very safe. Intelligent water meter is safer and more accurate than the original water meter. However, once the smart water meter is not displayed, either there is something wrong with the water meter itself or the battery of the smart water meter is dead. If the battery is dead, it needs to be replaced today. I will briefly introduce the battery replacement method of smart water meter.

Open the lead seal of the battery box, remove the screws for fixing the hatch cover, and take out the battery. The battery box is at the bottom of the water meter.

Press the buckle, unplug the connector and disconnect the battery buckle connection. The water meter uses two 3V lithium batteries, model CR 123A. Two batteries are connected in series, and the batteries are connected with the water meter through buckles.

Batteries can be bought online, just search for "CR 123A", and the price is around 30-40 yuan.

After buying a new battery, pay attention to whether the positive and negative electrodes are the same as the original battery, mainly depending on the connecting wires. If correct, insert the buckle into the water meter buckle.
