How is the timer powered? If by internal battery, is it rechargable or is the timer disposable when the battery dies?

It is powered by a a AA batt. this timer is nice but there is like 16 diff set points at only a min at the lowest set time. but it is ok.

Can this timer be used with. a12volt, automotive battery, to control 12volt led light strips, on a mobile display sign?

It need be connected to the power, then it can controller on/off.(in the timer switch, there's a capacitor)

There is internal battery( non rechargeable) just to keep the clock going, but to control you need 12+ volts to be able to function. I guess the internal batt is replaceable.if it stays plugged to power source will go without the batt. It worked fine for me, not a bad purchase.

It is not battery operated. There is a small battery that keeps the time correct in case of power outage but you need to get 120V power to the unit by plugging in to a wall outlet or running wires to it.

Right. This one isn't rechargeable, it needs to stay plugged in. They do have other models that are rechargeable, I believe. They are usually a bit more expensive. But keep in mind that those batteries will slowly die over time.

The MT13A Mini Timer uses 2 - AA batteries for backup of settings. Do not use rechargeable batteries.

Yes, the timers have a battery backup to retain your settings in the event of a power failure. The battery is charger when you plug the unit into an outlet. Let it charge for at least 10 minutes before unplugging. I'm not sure how long the unit will keep the settings stored during a power outage, but I have experienced a outage of about 2 hours and mine retained its settings. Hope this helps.

No, if you disconnect power you must manually turn it on. Cannot use it with an external timer.

The unit doesn't have an on/off switch, but the batteries seem to last a very long time as long as the timer is not running when the unit is stored.

Yes there is a battery that recharges itself and never needs to be replaced. I believe it will hold your settings for 30 days. It is a marvelous timer/switch and I highly reccomend it.Earl Tillman

It has a battery inside that allow you to keep the time scheduled, but to turn on/off anything you'll need an external 12vdc power supply. Follow the installation sheet that comes with the timer is very very simple.

Pulse it how? The timer runs on a battery, the relay is powered separately from whatever source you want. You can program the timer to open and close the relay at 12 different times, I think.

It operates on rechargeable battery :) It automatically shuts off after certain amount of time when it's not used. Extra battery can be easily purchased from Amazon.

It uses a button battery, I have owned it for almost a year and use it all the time without major issue. It uses the ultra lower power consumption bluetooth transceiver so I wouldn't worry about battery life. It is not rechargeable though, you have to buy a new one when it dies.

Hi Rosalyn, To keep accurate time, this unit contains a CR2032 battery inside of the unit as a backup power source. The battery keeps the clock operating in the event of a power interruption. Which means that it will not run for a long time if the unit uses battery alone. -Ely

yes, the clock is powered, and there is a built in rechargeable battery. The black wire and white (neutral) wire needs to be connected to a constant voltage source. The green connects to ground (bare wire) and the red is the timer output wire to control a light and/or an outlet.

Kristen, I have used these timers for years and the batteries last for months. The battery doesn't hold the valve on so length of time won't affect battery life. I believe you have a defective timer.

Yes the internal battery can be recharged. Have only had to recharge it once and did that in the evening leaving it on all night. I haven't found anything yet that would show the status of the battery, or it's level of charge.
