What is the life expectancy of the internal battery? Is the internal battery easily replaceable and how much is a replacement?

I have had one for over 20 years and it has just recently failed to take a charge. Amazon has a replacement battery. Search for Boosterpac ES2500 replacement. Remove 4 screws.

Yes, its very easy to replace the battery. Also I've had mine for 18 months and I haven't needed to replace it yet.

It has an internal battery, but it is not servicable. The battery is listed to be good for five years.

Yes, the battery is replaceable. I keep the unit in the charger 90% of the time but when I use the unit on battery it lasts about a couple of hours.

I don't think there's any easy way to get into this thing to change the battery, but you won't need to think about replacing the battery for a LONG time. Battery life is VERY good on a single charge (about 25 hours), and if you really need to run it longer than that between charges, you can plug it into a car charger or AC with an appropriate "power only" adapter.

The battery is inside the housing. Not sure if it is replaceable. I doubt it. It wasn't touted as having a replaceable battery.

The battery appears to similar to the ones used in a cell phone. It also comes with a charging cord, i just keep it plugged it all the time. It shows in the instructions you can leave it plugged in and it will charge to its capacity, then-not charge again until its needed. As far as easily replaced or upgraded? Easy to replace, yes. Easy to find that battery, i don't know. Upgradeable, not sure either. Sorry, this may be more info then you wanted and not the answer you were looking for. Hope it helps..

It has a 6 hour battery life. It is an internal rechargeable that is non-replaceable.

The calculator does indeed have an internal replaceable battery LR54 / SR54. To replace it, you will need to unscrew the back to access the replacement area. It is recommended to replace the cell every 3 years to avoid alkaline leakage into the circuitry.

I don't believe the battery is replaceable. I've had the prior version of this one for over 23 years and the battery still runs. Hope that helps.

The battery is not replaceable. It is supposed to last 5+ years. I have two that have been in use for over 10 years and are still working. One on a garden tractor, and the other on a log splitter. I just purchased 2 more last year to install on atv's I got for the grandchildren. I have read on the internet that people have cut them open (very carefully) and replaced the battery and resealed it. I may try this when one dies, and if it doesn't work I will just throw it away and buy another one.

It is a rechargeable internal battery not replaceable. Battery lasts a long time, lithium ion I believe.

No, this battery is NON replaceable, unless your really lucky.. You can take it apart and remove the battery but you can't find the replacement for it anywhere. I took the one I have to a batteries plus store and they had never even seen that type of battery before. Even a google search brings up some asian website that would cost way too much for it. It's some type of proprietary battery UNIDEN used for this monitor.

No it's not replaceable but the battery won't stop holding a charge for many many years. By that time you will have moved on. Also It has an internal overload shut off so you won't fry the battery.

Hi - No - the battery is replaceable and is under the unit or at the base of the unit.

The battery is replaceable and may be purchased from Audible Rush for $40. Don't know about different batteries.

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.
