Does the battery power the locking function or just the lighting function?

You need power to engage the locking/unlocking deadbolt knob. Without the battery, you have to use the key.

You have a turn key to lock and un-lock the door. the battery is for the light and the keypad itself.

locking and unlocking are done by manually turning the lever. The battery is needed to engage or disengage the mechanism that allows the lever to lock or unlock.

As has been stated, the battery engages the knob, allowing you to manually retract or extend the bolt. This probably greatly extends the life of the battery, by letting the user do the work of moving the bolt. When the battery gets low, you'll be warned by a a delay before unlock, a High/Low beep then 1 Red then Green light flash. Once it's dead the keypad will not function. The key will always work.

The battery power DOES NOT retract or extend the deadbolt. That is done manually. The battery powers the light and the keypad + mechanism that allows you to engage or disengage the deadbolt.

As far as I know battery power is needed to unlock. So may want to change he battery periodically, say once a year, not when it fails ( or you may still carry a real key). I haven't replaced the battery yet. We love this lock. Also, you should be ale to locate the manual online.

Both, when you press the keys, the they light up. I have had mine for 3 years now and just bought one for my daughters new house. I love this, you'll never lock yourself out. There is also a key if you need it, but the unit lets you know when to change the battery, it does last a long time though. I hope this helps!

No, the battery is built into the light. Also, the light is great when it works, but the design is bad because the chip is packed in too tight and causes it to fell. You cannot return the item either due to shipping the item with that battery. Speak to Amazon about this before you make your purchase.

Not sure about the battery, but it does measure FC and Lux with a flip of a switch.

None whatsever. I am a police officer and use the light almost every day with no difficulties at all from the light or the batteries.

There is a battery indicator on the main screen when on. The light stays on when plugged in

That's strange. I have a new version and an older one. The older one does NOT have a "lock" and "unlock" switch at all. But both versions come with a battery. The magnet on the old version is black and measures about 1 1/2" x 3/4". On the newer version, there are two small round silver magnets on the back. The newer one has 2 silver screws on the back and the older one has 2 black screws. Both have two white feet. So I'm thinking you have the older version without a battery.

No. To save on battery power, it only lights when buttons are pressed. I prefer to have even THAT option disabled. I have flashlights to supply power during outages. If you'd like to get one, go here; http://lightsngear.com

On mine it is a ring that turns one way focuses the beam the other way spreads. Don't know that it actually locks but has click turns..works well..have to say I love this light! Very bright!

Actually it does not 'lock' onto either battery as you do not have to use the batteries release buttons. The 20V has a more positive attachment than the 12V

Yes, just got mine and it would not work. HOWEVER, I discovered the problem ... If I leave the the little latch/key (for the Grip's battery compartment) in the OPEN position, power was supplied. Locking it would causes it to have no power. Obviously this is defective and is going back. Weird, but definitely the issue ... at least for mine.

The battery requires a "cage mount" that has two electrical contacts on the bottom that match up to two contacts on the bottom of the battery.It also requires an locking pin that locks the battery in the cage and holds it firm against the bottom contact points. The locking pin on mine uses a key to operate it. Hope this helps.

The headlamp has a lockout function. Press & hold the button to turn it on until the light on the side flashes. It is then locked.

No, the light just goes off when fully charged. You will get a full battery indication on the viewing screen when you turn on the camera.

This is from their installation manual: Programmable lock-hold time from 1-9 seconds (default at 3 seconds) Note: Longer lock hold time will reduce battery life when using alkaline batteries

the lock uses very little power, I would assume a 12v battery would work fine, I think creating a circuit similar to an emergency light would work without issues

Yes, that's all there is to it. But you also need to switch it on using the small lever that indicates "lock" You may also want to set the camera to use the battery in the grip first then the battery in the camera.

the lock doesn't lock itself, you either push the lock button on the keyboard or mechanically turn the locking mechanism on the lock itself. I'm very happy with this lock. you can buy AA Lithium batteries to extent the usable life cycle.
