does white rogers thermostat use any batteries

No. This thermostat does not use batteries. This is a primary reason for my purchase.

I replaced an old Honeywell thermostat which didn't have a 24v Common wire with the CT100 Z-Wave Programmable, so I've always used the 4 AA batteries to power it. They last forever, and power failures have no effect.

It does come with a small battery. We usually always leave it plugged in to electric but have used that battery for a short trip. (couple of hours) We plugged it in when we had access and all settings were still set. Very pleased with the unit!

Yes, the thermostat has batteries which retain the settings for power outages.

No. It has a internal capacitor that keeps the programming for several days without batteries.

Yes the thermostat's batteries retain the its settings during power outages. These batteries run down in about 1 day unless external power is applied however. The power from the thermostat wiring must be supplemented from an external source. I ran an additional cable from the furnace for this purpose and the thermostat now operates an monitors temperature in my vacation house. I also have a "NEST" thermostat ($250 @ LOWES) as well which has more features and is able to run solely on the 2 existing thermostat wires in the wall.

No. It does not require batteries. It uses the 24 volt power from the HVAC unit.

The unit requires power in order to control the HVAC system. Page 57 in the manual: Review Battery Tips 1. Replace the batteries as soon as LO Batt flashes in the display. The LO Battery indicator flashes in the display one month before the batteries run down completely. 2. Always use fresh AA alkaline batteries. Non-alka- line batteries do not last as long and can leak, causing thermostat damage. 3. Although the thermostat has a Low Battery indica- tor, replace the batteries once a year to prevent the thermostat and heating/cooling system from shut- ting down due to lack of battery power. 4. As a precaution, replace the batteries when leaving your home for more than a month to prevent your heating/cooling system from shutting down if the batteries run down completely.

Your power source is integrated into your thermostat wire. Its not a separate power source. Most HVAC systems have a 24v power integrated. The battery is just a back up and to keep your settings.

I don't know. Never thought of using it with a battery but Holmes should be able to tell you.

Not at all. Leave the batteries in in case you need them. Plug it in when you can.

No. Not really. It's cold here about 6 months out of the year. Never had any issues. I've only changed the batteries twice in about 14 months as well. Gets to maybe -20 on the coldest days. Mine are mounted under my porch without the outside shell however. Maybe different results while using protective case.

No batteries. Mine is the same, wired to transformer. Honeywell helpline is of little help to protect tradesmen.

Yes. I installed mine using a line-voltage (220v) thermostat with the heater unit turned to full warm position. The thermostat I have is a White-Rodgers purchased from W. W. Grainger.

I believe you're talking about the little demo batteries, which are not replaced with anything. You only need your 3 large batteries in that unit. Hope this helps.
