    • First, figure out a screw management scheme. This one's not so complicated, but it's a good habit.

    • Rotate the power switch to the unmarked "off" position. Don't worry, this is safe.

    • Remove three tri-wing screws.

    • Remove bottom cover and set aside the red power switch.

    • Open the inner case, using a flat blade screwdriver to open three plastic latches. Expose the circuit board and batteries.

    • Measure and record the old battery voltages, with the power switch firmly OFF. A new battery is about 3.3 volts, the bad ones seem to be about 2.8 volts.

    • Hopefully you've already obtained replacement batteries. Anything with a tab can be made to work. Here it's a 2/3A size battery with PC board pins. Not an exact match, but close enough.

    • To cut the old battery out: use strong side cutters and a back and forth motion. Leave enough of the tab you can solder to it later.

    • To remove using a hot/powerful iron: take out three more screws to remove the circuit board. Heat up each tab in turn and pull up on the battery. Leave as much solder as possible in the hole for later.

    • Double check the power switch is off, and the polarity. Finally, solder the new battery in.

    • Double check the polarity of the batteries! If you get it wrong, the battery will probably catch fire.

    • Flip the power switch to the middle "ON" position. Be careful, the third position is "drain battery and discard unit".

    • Hold the center button until you hear one... two... three beeps. Release, and your unit will be reset to defaults.

    • Flip that power switch back off for safety.

    • Yikes, it sure makes a forlorn sound when you flip the power off, eh? Reassemble. The only tricky part is the switch, but there's a little arrow to help you get it lined up.

    • Properly dispose of the battery. That means, not in the trash. Google it. Or see https://greencitizen.com/lithium-ion-bat... or in the USA https://www.call2recycle.org/

Conclusión

You saved an expensive detector from the landfill. Yay!
