You mean the 'Not-so-Smart-Tag' kah? I'm a first time user. Was wondering how long before I need to change the battery. When I googled for the infomation, some claimed their batteries only lasted few hours only. Some others claimed theirs lasted 18-24 months. I wonder if some guys received 2nd hand batteries from T&G. Scared pecah cermin if stick to windscreen but do however feel silly having to hold the tag with hand when approaching the Smart Tag lane.
I'm a daily user of Smart Tag. Went thru 3 generation of tags. Don't let the other scares you on the battery life. If it drained battery within couple of months or less, garantee the smart tag or the battery spoil liao. Change batt, if still same, tag spoiled. One of reason for battery kaput very dast is those leaving on windscreen stand, etc under hot sun, sure battery drain MUCH faster.
A single 9V battery will last abt 12 months for me. I use it every working day, 4 ~ 5 tolls daily. Which silly bugger goes to unplug batt and plug everytime to use, crazy.
I don't put tag or any sign of tag on the windscreen, takut pecah cermin, it happens to lots of ppl.
Everytime I hold tag when near toll. If feel silly, put the tag on you dashboard although it might slip or scratch them.....holding will be safer in any case. You won't feel silly coz LOTS of smart tags veteran actually hold their tag and slip it back under their compartment upon usage. Also by holding and keeping it back to compartment, it won't be exposed to direct sunlight heat, battery will last way longer.
