re-installing the auto-gate motor after the flood, everything is fine except the sensor battery is dead.

it is a pair of low drain 3.6V Lithium battery ( ER14505, UM3, R6, AA ).

where could I find this battery, any battery shop ? for battery replacement at auto-gate dealer, it could be a thousand baht story.

Take the dead battery with you, a camera shop would be a good starting point for Lithium batteries

good idea too ! that will be anyway cheaper than a dealer call :-)

the original battery is nothing more than a blue wrap, labelled ER14505 and 3.6V. now, just replaced x2 standard 1.5v AA batteries into the auto-gate sensor and it works ?! not sure how long these 1.5V batteries could last.
