does it have a replaceable back-up battery ?

The package states "self recharging battery", but nothing in the package insert indicates it is replaceable. There also does not appear to be an easy way to open the unit. Try to contact the manufacturer and let me know what you find out.

Yes & an extra battery. Mine has been stored for some months. I pulled it out on Thanksgiving & the spare battery still had a full charge :-)

Yep, there is a replaceable battery. Lithium ion, flat cell phone like battery. Don't have it with me to quote specs, however.

Yes, it has a built in battery (non-replaceable). Runs several days on a single charge. Works very well so far (9 months).

this does have a replaceable battery.Mine has a BL-5C Li-ion battery. Cover comes off where all the input are to reveal battery . I would advise getting some extra batteries if you plan on playing this very long

I do not know because I have not used that feature on our phone yet. I know there are no batteries for back up.

The battery is built in. I haven't had to replace mine, but the specs do state it is possible to replace when it stops holding a charge.

Yes, the battery is replaceable. Its the same as a fairly common cell phone batt. The owners manual gives instructions.

Yes it has a rechargeable battery - comes with a cord and plug to that it can be plugged into an electric socket to recharge!

It has it's own built-in rechargeable battery. Not sure if it's replaceable though. The FM reception must depend on your location because mine was very good but I'm in a big city.

No it does not, but it is an excellent spare battery if you already have one

No battery backup is included in this package. Check the website to see if you can purchase one separately.

Yes there is a backup battery. Since I have had no problems with the chair, I am sorry to say I haven't even thought about what I would do if it needed service.

Yes, the battery is replaceable. The front cover is removable and then the battery slides out.

No it doesn't. It takes 2 AA cell battery's instead. So their always replaceable.Nice little camera, for the price.K.O.

Yes to your first question. As for the battery back up timer I haven't seen one of those.
