When Ac In Use, Should Laptop Battery Be Taken Out?

Hi, Which is best, I don't use the battery that much, Thanks

 

No power cuts ever where you are??? That's when a battery earns its keep.

 

No. Does your laptop user guide say to? No.

There's no need to try to second guess the manufacturer.

 

I was concerned with over charging it while using the AC?

 

In modern Laptops, Smartphones en similar devices, it's highly unlikely that the battery will be over charged.

 

Eldon, Thank you, that's what I wanted to hear.

 

In fact, there are design features built in to prevent that.

 

I never take batteries out of laptops while charging. I have however, been given 5 Dell laptops that were retired from a relatives office where 3 of the battery packs were swollen. One to the point that it was looking like a balloon was in the case. Replacing the batteries restored the case appearance snd computer functionality, but batteries will still go bad and swell. There were 2016/17 vintage machines

 

It should be noted that batteries can also become swollen due to heat from other sources - like being left in a hot car.

Chargers are designed and selected with the capability to run the notebook and charge the battery at the same time.

 

In the case of mine, these laptops were used as desktop replacements and stayed in an office. Bad batteries will swell...

 

Yep. Depending what is wrong with them, some will.

 

I just had to replace my HP laptop battery from a power surge.The only time you should have to worry about it is when a power surge makes it unusable.My laptop still runs perfectly.

 

Batteries tend to be very tolerant of excessive spikes and surges. So that must have been some surge. Are you sure it wasn't a faulty charger? Or just a faulty battery that decided to go at that point in time? How old was it?

How do you know it was a surge?

 

The laptop is 7 years old.The laptop pretty much stayed on 24/7.And never had an issue.Power blinked one day and the battery stopped working.Tried every thing to reset the battery settings in windows.I ran HP battery test and it would either say 50% or 0% and not even come up on windows.

 

Okay, but I still suspect the problem was actually with the charger and/or charging circuits in the laptop.

In any case, I am glad it seems to be working now.

 

There's more to batteries than just cell construction. The power supply to charge them needs to be regulated. AC power must be rectified to charge a DC cell. The fact that the system can detect the charge relies on the loose equivalent of a voltmeter sensor. The PSU is the first PCB in the line of defense against surges, unless you are plugged into a backup PSU. If any of the sensor or regulating circuits are faulty, they can indicate a battery has failed even if it has not. And as mentioned above, there are physical signs that a battery has reached the end of it's service life/maximum discharge cycles.

Exempli gratia, even a standard lead/acid car battery maxes out at about five years on average. If you treat a deep cycle nicely, it could last longer...
