I first tried to do that as I went to batteries plus but I would have to solder it so it seem more prudent to buy the whole apparatus.

Bruce,I am afraid I am not able to answer your question. We bought the house February 2011 and the system was installed. The 475LM did fail and liking the fact that I could raise the garage door in the event of a loss of electricity due to storm or what have you, I elected to replace it. I bought the unit as shown and installed it in to the existing location.I am comforted by the fact you've had yours for 7 years. I had no idea how long the previous owners had theirs.Best Regards,Kevin

You can replace only the batteries but I would not do so until needed. You can test them by unplugging the AC and running the opener. I bought the entire unit since it was only a few dollars more and kept the control board from the old unit for a spare since I have five garage door openers. I have had them for 8 years and this is the first time I had to replace any batteries.

From what I remembered it was close to the cost of the backup system - maybe 10 dollars less and he had to order it first. that was around a year ago since I have two garage doors and recently had to replace the second one. You might want to call batteries plus if you have one near you or just google the battery itself. it is a fairly common one.

I've never replaced the batteries. We've had it at least 3 years if not longer.

I've not had to replace the battery. Perhaps the manufacturer could give you an answer. Locally we have a store that advertised they have any kind of battery needed so if I did need one I'd try that store first. They might have economical batteries and would be a local access if you needed more batteries in the future . Sorry I couldn't be of more help.

Typically, battery can last up to 3 years, if kept on regular charge cycles. We recommend changing battery every two years.

My experience has ben different. Have had system running for five months and batteries still running and show 2/3 charge left. Due to other's comments, I bought a bulk pack of the batteries in advance, but have yet to use them.

I've only had it for a week, so no battey problems yet. It lasts my whole 10-hour work day on a full charge. There aren't any instructions included abot replacing the battery, but it looks like someone else responded and said it IS user-replaceable.Li-ion should last for years, but good battery maintenance will help extend the life. For at least the first 10 cycles, I charge it fully, then drain it completely. Don't recharge when it drops to 80%, 60%, etc. The performance doesn't suffer at all even when it is almost dead. That should help you get the most life and best performance.

We have not had to change the batteries and my husband uses it quite a lot. It must be working since we have had it for over a year.

I change my batteries about every 3 or 4 months and they seem to be working fine. When I do change the batteries the "rocks" are still working but I don't want to chance having them go dead.I hope this helps. I am not sure but I think the instructions give you the "company" answer.

I've never had to replace it and use it constantly (1+ year I think). It's one of the few things that I don't have to recharge nightly! ;-)

The information says its a "lifetime" battery if I remember correctly. I figure even if I replace it in every 7 or 8 years for my own sanity, then I've still gotten my money's worth in savings on 9V batteries!

You cannot replace this battery, at least without some electronics trickery. I have purchased three of these headphones and used the first two heavily for three years. They finally started falling apart and the battery life started getting bad, but I would estimate I wore each unit 3,000-4,000 hours before they wore out. I highly recommend them. Some might feel discomfort at first (due to pressure) but they conform to the shape of your head after a while.

Have had a set of batteries (alkaline) in, for over a year, and it still functions fine.However, I would suggest changing them every year, or so. Beats coming home to a dark porch/front door.

I suppose it would depend on how often and how long you use it. Also what kind of batteries you buy. We use ours often, and sometimes for a long time, and I've only had to replace them once, after about 2 months. You might even consider rechargeable batteries, and have an extra set ready to go. Save a bit that way.

No, the rechargeable battery inside is not replaceable. I use mine almost every day for over 8 months without any change in battery life. If you're worried about the battery not being able to hold a charge in a few years, then you may want to contact the manufacture to see if they offer a battery replacement service.

Since the battery is not easily accessible, replacing it may be problematic for the average consumer. Having said that, batteries are getting better all the time and I have other products where the batteries are still good after ten years of use. I see no reason why the batteries in this headset wouldn't provide years of trouble free service as well.

You cant, unless you take them out. I just keep back up batteries from the dollar store. You could keep t the back cover off and take them out. I only replace every 4-6 months.

According to the information I have with my manual, the battery is not supposed to be replaced. The battery, with proper care, is designed to last quite awhile, but it depends on how much you use it. I hope that's helpful.
