Rechargeable batteries have a finite life span. Since this is a fully enclosed unit, how do you change the batteries when they die?

you charge it via the USB - which i think you are probably clear on... but if the internal rechargeable batteries ultimately fail, then i believe it is time for a new speaker... i do not believe you can replace them.j

I don't expect to ever have to worry about the battery. These type of batteries last through thousands of charge cycles so if it fails in 10 years I will just buy a new one.

You can't change the battery. It's permanently closed. I don't think you've been able to change the batteries in small calculators for 30 years.

The instructions say to only use the rechargeable battery that is included but I used regular batteries when it died one day and they worked fine. I only used them for a couple of hours then charged the unit again and have no problems since. I'm guessing you could also use any rechargeable AAA, but I've not had these long enough to run the included batteries out.

If the replaceable batteries go dead you can simply put in some new batteries and nothing is lost. However, if you drop the unit in water or drop it from a high place onto hard surface, then the unit will probably be ruined and you won't be able to recover anything. Yes, it would be nice to be able to backup your data onto a flash drive and adding a USB port would be nice touch. Perhaps the manufacturer will take note of these comments.I've purchased 3 units so far and will continue buying them as gifts to family and friends. This really is a great product and something I used everyday. If the replaceable batteries go dead you can simply put in some new batteries and nothing is lost.

We have not changed batteries in 3 months of use. The timer function is used everyday. However, don't drop the timer in hot liquid - that will kill the batteries. Other than user error, we have not observed that problem. We use alkaline cells in our, not rechargeables.

I keep batteries in the unit so it is ready to deploy in an emergency. I replace the batteries yearly. I have a battery change day once a year for all my devices like emergency radios, flashlights, etc.

Batteries are built in and rechargable.If they go bad you can replace them.

Great question, never tried with rechargeable batteries but this is the best Mighty Bright unit hands down.

But, to your second question, the battery is not replaceable. There are sites on the internet where you can find out how to replace the battery though. My guess is that by the time the battery dies it will be time for a new model anyway. The battery should last at least 5 years I am being told.

Most likely you have to charge the new battery first before you can use it. These type of rechargeable slowly discharge themselves even if it is not used. The fully charged battery usually depletes in several months. The new battery may or may not have some charge left, depending how long it has been on the shelf. Also, it is recommended to fully charge the new battery before the first use.

It's rechargeable, so I can't remember if you can replace the batteries or not. It charges in the base.

You might be able to. Unscrew the sides and if the rechargeable battery isn't soldered in, it might be replaceable.

The batteries are internal but there is a key that can be stored in another location in case of a dead battery.I would assume if the battery dies it would stay locked and you would have to use the key to open it.

There is no charger in this unit. SO it lasts as long as the batteries do. You can use your own rechargeable batteries but the unit will not charge them. When the AC pin is plugged in it overrides the batteries.

Yes you need to change the batteries but you can use rechargeable batteries.

You can't, because the rechargeable battery is built into the unit and isn't designed to be removed by the consumer. I find the battery lasts around 3-4 hours on a full charge.

I use regular replaceable batteries and it has a little button you push to check them. But I don't see why you cant use rechargeable.
