Question

How to Prolong Toshiba C840 Battery?

Aug 11, 2016 7:57PM PDT

Hello everyone,

I use this Toshiba Satellite laptop all day, from 6:30 in the morning until 5 pm. I then let it sleep until 7 pm and resume for a couple more hours before shutting it down.

I use the laptop to write and watch some YouTube videos (no video games, photo editing or other tasks).

My question is: would it be better to do partial charge and discharge (80-40 is what I'm doing now) repeatedly, or should I just do the 80-40 once and leave it plugged in?

I am worried that repeated charging discharging might shorten the battery life.

Thanks.

Why not have it plugged in continually?

I am worried that keeping the laptop plugged in continuously might damage the battery.

May I know how long you've been using the HP while it's plugged in?

It's common practice for everybody.

The IT-service staff never advised to do it otherwise, not on the new HP's and not on our old Dell's, that easily lasted 4 years like that.

That's a myth.

It won't help folk that worry needlessly so here's the Battery University on that.

http://batteryuniversity.com/learn/article/do_and_dont_battery_table reads to me that I just leave it plugged in.

However a few of the office laptops have a nifty option to limit the charge to 80% which is very nice. Either way, your choice.

I've found folk want to discuss this with no end in sight. Here, we just plug it in and take the 80% setting if we can. We have yet to lose a battery in 5 years. Some of the oldest laptops if 10 year old batteries that while only hold half the minutes charge, we are not replacing them.
