Installation

Select your device to see how to replace its battery. Each kit has 25 batteries; the tab says which kit your device takes.

Kit: BAT4

Open the Transceiver

Press the tab to open the Transceiver, then take out the old battery.

Side view of a TR4 Transceiver with its cover swung open on the hinge at the right. A dotted red arrow curves up and over from the left edge to show the cover lifting open. The old battery is lifted up out of its holder (red arrow pointing up), and a dotted red line shows its white plug, on a red and black wire, unplugged from the socket on the circuit board.

Install the new battery

Attach the new battery's cable first, then set the battery in place.

Side view of the open TR4 Transceiver. The new blue battery's white plug is pushed into the socket on the circuit board (red marks show it clicking in), and a red arrow points down: press the battery down into its holder, with its wire running over the top.

Check the meter wire

Make sure the wire to the meter is still secure.

Test the connection

While the Transceiver is open, press the red Test Connect button. If you see two green blinks, the Transceiver is good to go. If you don't, other equipment on the property may need attention: see Troubleshoot a Connection alert.

Inside the TR4 Transceiver, seen from above: the blue battery along the top with its plug connected at the right end, the meter wire coming in from the left to a blue screw terminal, and the red Test Connect button on the right. A curved red arrow points to the red button from below right.

Close the Transceiver

Snap the cover shut and return the Transceiver to where it was installed.

Kit: BAT4

The kit includes two grease packets for the battery cap's seal.

Open the battery cap

Put the removal tool (or a large screwdriver) in the battery cap and turn it left until the cap comes loose.

Close-up of the TR4-X battery cap: a round cap with a plus-shaped slot whose pointed end faces a triangle mark on the housing. Two red arrows circle the cap counterclockwise: turn it left to loosen it.

Replace the battery

Pull the old battery out until you can reach its wire connector. Disconnect it and connect the new battery.

Grease the gasket

Apply grease from the kit's grease packet around the rubber gasket on the cap. This keeps the seal waterproof.

A grease packet torn open at the top. A red arrow pushes up from the bottom of the packet to squeeze the grease out of the top, and a red line leads from the grease up and to the right, toward the cap's gasket.

Close the battery cap

Put the cap back in and turn it right until the arrows line up.

Test the connection

Swipe a magnet near the magnet icon on the Transceiver. If you see two green blinks, the Transceiver is good to go. If you don't, other equipment on the property may need attention: see Troubleshoot a Connection alert.

Kit: BAT301

You'll need the NCSS mobile app, a DC301 Direct Connect and a magnet.

Remove the Remote Reader

Pull down the locking tab and remove the Remote Reader. Pulling from the bottom detaches it from the mounting plate most easily.

Open it

Turn the base counterclockwise, then carefully take out the internal unit.

Mark the battery replaced

On the device details page, scroll to the bottom, select Battery Replaced and tap Save. Swipe the magnet again to check it took.

Enter a new IMR

Swipe the magnet to reconnect the RR301 to the DC301, enter the new IMR (Initial Meter Read), and check the multiplier is right. Tap Save, then swipe the magnet again to check it took.

After replacing a battery: update the IMR

If a device was without power for a while, some usage during that time may have been missed. To keep its reads accurate, enter a new IMR (Initial Meter Read) when you replace the battery. In the NCSS mobile app:

Use the Barcode Scanner tool to scan the device's serial number.
Reset the device manually.
Tap Quick Actions and enter the new IMR.
