I currently own a new Sony notebook that I got 2 months agao and I was wondering if setting the battery charge to 50% will make the batteries life longer on the long run? Meaning it will hold the charge closer to new even when it's like 4 years later.

Hello

Very good question, My opinion:

Setting the battery charge to 50% won't really help.
I believe it is best to charge it 100% and let the cells drain before recharging (Maybe 10% left).
This way there are fresh electrons in the cells every new charge. This is the way I make my lithium ion battery last longer. (or so I think..)

But we all have are different opinions about it, and this is what I make sense of. I need to do some further investigation on this subject.

Good-luck :hysterical:

Well on my Sony notebook it says that it will shorten the battery life to 50%/80% per charge. It also says it will reduce degradation and increase the number of recharge cycles for the battery.

Basicly I can have the computer only charge upto 50% or 80%. It said that if you use the battery alot then set it to 80% but if you use the AC power the most then set it to 50%.


But I guess you are saying that it's best to take off this feature and make it charge 100%.

If your laptop rarely moves around you should take out the battery when using it which makes the battery last longer.

Well I do know one thing is that my computer doesn't keep toping off just because it's less than 100% or even less than 50% or 80%. So I thought it would be fine leaving it but do you guys still think I should take the battery out? Right now I have mine charged upto 100% right now. Before I had only charged upto 50% for a long time.

Take out the battery if your laptop is gonna sit in one place for a long time.

When I do take the battery out should it only have 50% charge or is it ok to leave it fully charged to 100%?
Btw does the heat from the notebook make the battery go bad faster? Since I heard some people say that.

It's ok to leave it fully charged to 100%. I doubt that would happen and also the laptop would be lighter now :thumbup2:

So the heat from the notebook won't harm the battery in the long run? If so why is it best to have the battery out if my notebook won't keep toping off?

The following is an excerpt from thisarticle.

A lithium-ion battery provides 300-500 discharge/charge cycles. The battery prefers a partial rather than a full discharge. Frequent full discharges should be avoided when possible. Instead, charge the battery more often or use a larger battery. There is no concern of memory when applying unscheduled charges.

Although lithium-ion is memory-free in terms of performance deterioration, batteries with fuel gauges exhibit what engineers refer to as "digital memory". Here is the reason: Short discharges with subsequent recharges do not provide the periodic calibration needed to synchronize the fuel gauge with the battery's state-of-charge. A deliberate full discharge and recharge every 30 charges corrects this problem. Letting the battery run down to the cut-off point in the equipment will do this. If ignored, the fuel gauge will become increasingly less accurate.


Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.
