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

Adventurer, Thank you for your inquiry. Typical battery life is 1 to 2 years. For best battery performance and life, keep the battery fully charged throughout the life of the battery.

The battery can't be replaced by you. It needs to be sent in. As for how long they will last before replacement, i don't know. A long time probably. I've only owned one for a few months so i can't be the judge on that. But my friend has had his for a few years and he uses it a lot. His is still working fine on the original battery.

Sorry, I've never tried to replace the battery, so I wouldn't know? I really don't use mine anymore and I'm looking to get rid of it. It's just collecting dust in my garage.

The battery is rechargeable using a standard micro USB power cord (which is included with the unit). Unless your device is defective, the battery should last for a long time. After several years, I've only had to replace 1 battery for the three units I've owned. A replacement battery (which I bought on Amazon) cost under $5.

I really don't know I don't think you can actually replace the internal battery or even if they actually sell it, I'm sorry I could not be of any help

A prior review states ... " Unfortunately, the unit is sold with a cheap 12 Volt, 7.0 Amp-Hour internal battery that cannot hold up under the rigors and demands put on it by the general consumer. Anyway, the battery in any of these types of portable devices doesn't last forever and will eventually have to be replaced. Think of is as normal maintenance, to be done every two to five years, even with the best of batteries. But a simple change to a 12 Volt, 8.5 Amp-Hour, high-rate replacement battery will greatly enhance its performance. Without going into a stuffy brain-dump: A simple 21% increase in Amp-Hour capacity (to 8.5 Amp-Hours) will double the amount of work the fully charged battery can do, under load, such as the internal 12 Volt compressor motor. The "high-rate" designation is also a type of battery that is designed to take heavy loads without damage -or shortened battery lifespan." I have not actually replaced the battery, but it has every appearance to be replaceable

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.

Replaceable, I believe it is a CR battery so they are fairly spendy to replace

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 know about the overall lifespan of the battery, but I do believe replacements are available or at least new pens are and I don't believe they cost much. It's like 15 dollars for a whole new pen. I've had mine for a year now, with daily usage reaching over 8 hours a day sometimes and I've gone as long as 2 months without ever charging it and still no sign of it slowing down.

There is no internal battery. It's basically a portable power strip / surge protector so it will only work if it's plugged in.

It's an internal battery. Doesn't seem like it's one that you can swap out. I have had no issue with the battery and it seems to have a decent life.

I don't believe that the battery is replaceable. The package says that it is a rechargeable NiMH. You might be able to get at the batteries by removing the two small recessed screws near the bottom of the timer.

the battery is not designed to be replaceable. I have read that some people have opened the back and found that the battery is soldered in.

I don't know the life span of the battery. I still have the same one that came with it when I bought it back in December. Maybe someone who has had one of these longer could give you a better idea about the battery life.

The battery is not easily replaceable -- you need to remove the back cover to access it. That isn't too difficult, because the laptop uses standard torx T5 screws. Still, its not simple. However, I've found the battery lasts nearly 6 hours unplugged for typical web browsing, which is good. Also, I've had the computer ~4 months and the battery life hasn't gotten any worse.
