Compatible battery and charging

[Leo235]

Hello, I have bought a compatible battery for my laptop recently and I would like to know if the charging directions for the first time use make sense.The compatible battery  is  a Li-Ion.

Isn't lithium batteries with no memory effect?Given that, isn't only needed to charge and discharge it normally(when remaining power is nearly 10-20%) and avoid recharging it till exhausting battery power, because it will bring too much damage?

Directions

1)charge for 1 hour with the laptop turned off 

2)continuous charging for 24 hours(no matter if it's turned off or not) even if it's 100% charged after one hour 

3)use the battery until it's discharged to 5% 

4)repeat 1,2 steps for 3-4 times

Who told you to do this? No you want to try to avoid, if possible discharging below about 15-20%. Li-ion does have no memory effect. Ni-Mh batteries have not been around since about 1996 and Ni-Cad even longer than that. They were the kind with memory effect but its amazing how much "urban myth" is still out there based on problems with Ni-Cad in particular that have not been an issue in nearly 30 years.

So charge it up all the way up and then begin using it i.e. you can then unplug and go. When there is an electrical outlet use it. When you have to, run it on battery. That's all you really need to do. You do not need to do 3-4 full cycles right off the bat. 

Post back with any more questions.

At first, thank you for your answer.

Well, my previous battery was a  compatible one as well(10.8V 4400mAh while the new one is 10.8 5200mAh).

The package of my previous battery included a piece of paper written by the seller(local one) with the above-mentioned directions in my initial post.In  battery's manual  it was written: ''Discharge the battery to 2% and then charge fully to 100% for the first cycle.''

My new compatible battery doesn't include any info about charging so I was wondering if the directions of my previous one should apply.I asked the ownwer of the store I bought it(different store) and anwered me that I should just charge it fully at first,discharge it to 10% and follow the rule of 10%-80% for charging.

The last advice is not too bad. The 80% rule keeps the battery chip from chalking up a "cycle" so theoretically it will last longer. I don't see the need for that and charge mine to 100%. I also try not to let it go below 15-20% but you can get by with dropping to 10%. If you routinely let it drop to below 10% you will damage the battery that is true.

I see. 

So, for the first use I should charge it all the way up, unplug and begin using it until it drops to 15%-20%,then plug it again.

Yes I think you have got it. Do that, and use AC power when you can and battery when you must and you will have a good battery to use for somewhere between 2 and 5 years. And then it has to be replaced.
