No manual with my chromebook - just a start-up pamphlet - maybe there is something hidden in "help".
Prolonging a laptop battery?

I did note that your chromeboook has 15 hrs - that's impressive. Do you know the brand and model number?

It has shown over 20 hours at times - has now been running on battery for a bit (I want to test recharge from a powerbank) and is still showing 15:48 left.
It's this one:

C722
though I am a bit confused by some stuff from it which says it's Mediatek.
Am also confused by different specs I have seen for inputs.
But I am very happy with it.
Feels very sold - heavier than my last small one but it has a bigger battery.
Got it for £170 delivered.
You don't really need an instruction manual with a chromebook - you can unpack one and have them running in no time at all.
If you have any more questions about it, just ask.
Here is the guide on battery usage for your model - Page 14.

Media Tek is a CPU or processor used. Common processor is the Celeron from Intel for this range of laptops. This is an alternative.

thanks arrowfoot, though from a very quick scan of that booklet (I do seem to remember my old one had an online book) it doesn't offer a lot of help. It does say:
"Constantly charging the battery/device when already at full capacity" but doesn't make clear whether that includes having it plugged in while using. Most folks know I think that you shouldn't keep an off device charging beyond its full time, or even less. I gather that no Chromebooks have a smart battery function like @ColinJ 's above and my Lenovo PC laptop,
For the record, am doing this unplugged - battery showing 74 percent, 14:39 time left.
I have by the by seen advice that a battery is seriously on its way out when a battery health check returns a figure below 80 per cent - have no idea if this is true.
Don't worry the technology has advanced that these batteries can go the distance and plugged. I am still impressed how far it will go. I read some reviews on your model including running a movie on loopback and it went to 14 hrs.

Form my understanding charging and discharging Lithium batteries is what wears them out so if you have the ability to leave it plugged in then that's the best bet.
I have some wireless portable speakers and they are designed to be docked on the charging loop when not in use, the BMS sorts it out.
All Lithium Ion devices have a Battery Management System and it's designed to take care of the batteries and also act as protection against damage.
Multi cell packs can require balancing, so leaving them on charge at 100% enables the pack to (slowly) balance the cells.

Thanks for the info arrowfoot - to clarify, in case of misunderstanding, my main concern is to maximise the time the battery runs, is usable, in years - ie total life - rather than the time running on batteries per charge (which I know will fall) - chromebooks are great on this.
This new one has a 4266mHa battery, which is not only bigger than my old 11.6 inch one (3489) but actually even bigger than my 15 inch chromebook which makes do with 3920. I am perfectly happy to run this new small one as my main chromebook/computer.
I understand. It will last longer than previous generation of future Ion Lithium batteries. And you do not have to follow a maintenance routine except when you cold store it which is unlikely as we use these on a daily basis.
I do remember when we had to do deep discharge routines and the much shorter shelf life. I can see my colleagues and myself have no issues with current generation of laptops and we have been using it for a number of years. .
