A perfect battery usage for lenovo y700 [tips and advices]

Hey every one , as in the title , i want to know what is the correct or perfect way to use a li-on battery like on lenovo y700, some articles says that we should connect the ac once we are under 20-15%, but others says that when we first have this kind of batteries , we should ac until we reach the discharge threshold defined by windows wich is 7% on most laptops and sometimes 5%.

I m very confused , so should i connect my ac now (at the moment i have 20% left or should i keep using it until i reach the threshold ,well i think i ll go study and return to see your answers Smiley Wink )

Hi wassim320,

 

It doesn't take long to learn what helps preserve the current charge on the battery. What's not well known is how to care for the battery itself. That's just as important. Doing so allows the battery to operate efficiently. Here are a few ways to keep your lithium-ion batteries healthy.

1: Keep your batteries at room temperature

That means between 20 and 25 degrees C. The worst thing that can happen to a lithium-ion battery is to have a full charge and be subjected to elevated temperatures. So don't leave or charge your mobile device's battery in your car if it's hot out. Heat is by far the largest factor when it comes to reducing lithium-ion battery life.

2: Think about getting a high-capacity lithium-ion battery, rather than carrying a spare

Batteries deteriorate over time, whether they're being used or not. So a spare battery won't last much longer than the one in use. It's important to remember the aging characteristic when purchasing batteries. Make sure to ask for ones with the most recent manufacturing date.

3: Allow partial discharges and avoid full ones (usually)

Unlike NiCad batteries, lithium-ion batteries do not have a charge memory. That means deep-discharge cycles are not required. In fact, it's better for the battery to use partial-discharge cycles.

 

There is one exception. Battery experts suggest that after 30 charges, you should allow lithium-ion batteries to almost completely discharge. Continuous partial discharges create a condition called digital memory, decreasing the accuracy of the device's power gauge. So let the battery discharge to the cut-off point and then recharge. The power gauge will be recalibrated.

4: Avoid completely discharging lithium-ion batteries

If a lithium-ion battery is discharged below 2.5 volts per cell, a safety circuit built into the battery opens and the battery appears to be dead. The original charger will be of no use. Only battery analyzers with the boost function have a chance of recharging the battery.

Also, for safety reasons, do not recharge deeply discharged lithium-ion batteries if they have been stored in that condition for several months.

5: For extended storage, discharge a lithium-ion battery to about 40 percent and store it in a cool place

I've always had an extra battery for my notebook, but it would never last as long as the original battery. I know now that it's because I was storing the battery fully charged. That means oxidation of lithium-ion is at its highest rate. Storing lithium-ion batteries at 40 percent discharge and in the refrigerator (not freezer) is recommended

Final thoughts

Lithium-ion batteries are a huge improvement over previous types of batteries. Getting 500 charge/discharge cycles from a lithium-ion battery is not unheard of. Just follow the above guidelines.

 

Hope this help you and let us know how you get on

Re: A perfect battery usage for lenovo y700 [tips and advices]

i prefer you have your battery on charge while you are gaming with it.especially with games who require a lot of power.this will give you better performence and will make you not use the battery while playing so you can have your battery life longer.but be sure to take the power off when youre done with gaming because having it too much charged is not good.you can use a gaming software called geforce experience which has battery life manager type of thing to manage it.

Ok neo ,first , thank you for your tips , so from what you said , i understand that the battery should be properly used , especially with the temperature and the discharging, so for the moment it s very cold in my country (i m happy for my battery lol) and i never dischargit over than 90% , windows 10 tells me automatically to connect the ac ,i turn my pc off and let it load for 120/140min (to 100%)

Re: A perfect battery usage for lenovo y700 [tips and advices]

Resi , i have already geforce experience , but to be honest i don t use it a lot , for the moment i ve just installed minecraft , and it runs smoothly in ultra , but idk why i can t use the touchpad while i m moving , so i have to stop and look around (move the camera) then walk again.
For performance mode , i can activate it from battery settings , otherwise i think with ac connected it will supply the gpu more...but i think it s not very healthy for battery life to connect the ac and use the laptop same time because the power will be divided...
However ,ill see,that battery settings...thank you for this information , i didn t knew , that geforce experience had a battery manager.

Actually i found a "conservation mode" in lenovo settigns wich allows me to keep the ac connected while the battery is on the battery ,but it s stops charging when it s 60% so i begin to use the pc with the just the power of the ac

Re: A perfect battery usage for lenovo y700 [tips and advices]

Hi! I have a Lenovo Ideapad Y700 too! This has a non-removable battery! I read some blog they said that you can leave the laptop plugged in at all time! Is that true? This is a gaming laptop and for high performance is better to be plugged? What is the best way to protect the battery for a long life! Thank you!

Re: A perfect battery usage for lenovo y700 [tips and advices]

for me conservation mode is the best , i ve used it for 2weeks and test the battery i play the chronometre to know how much time my battery stands , it was 3h49min for 21/12/2016 for the month of junuary i used my laptop with conservation mode and i charged it to 100% then run my laptop with the battery power to test and see if the battery has lost some lifespan ,it is said that in the 1st 10 cycles of battery life we will notice a little reduction in the battery life ,but no , for me my battery stands for 4h3min in 21/01/2017 and i reached now 15 cycles so , for me , i me very satisfied with lenovo y700 battery life as a gaming laptop for this price ...
