do they have memory? like can i take it out of the AC and use it till 70% then plug it back in and so on. or if i take it out its best i let the battery run till its almost empty. etc..
or can i just use battery , adapter at my own ease and not worry about battery life shortening

If you're asking about battery life, than using AC won't shorten it if your using the computer. If you leave it on charge, it will shorten the life over time. Taking it out repeatedly is probably more damaging though.

Also, it is recommended that the batteries are drained to 0 once every month and then recharged so that they can keep their charge.

If the goal is to maximize the life of the cell, then there are lithium battery technologise that should NOT be fully drained prior to recharge.

It's all about the chemistry and battery mechanical design. NiCd or NiMH cells do not work the same as Lithium cells, and the standard rules for NiCd storage should not be broadly applied.

Experts state that NiMH and Lithium cells will in GENERAL, have longer lifetimes if stored at about 40% of their full capacity. Some experts go on to say that if you have choice between storing a depeleted lithium cell and a fully charged cell, store it fully charged. However, remember that there are added safety considerations when storing charged cells.

In addition, many lithium battery packs have internal electronic "smart" charge regulators...even the tiny cellphone lithium packs. They cannot be overcharged in the same way that NiCd or NiMH cells can be overcharged.

For definitive information on your particular cells, you should go to the manufacturer website, or Google for websites that have up-to-date information on your particular lithium cell technology.

Note that there are different types of lithium cells and their charging, handling, and storage requirements can differ.

just use it as normal... meaning ... use it with AC adapter, use it while on batteries, or use it in a docking station... just realize that you should be looking to replace your laptop battery in about 2yrs or little longer. Lithium batteries are much better than nicads and can take more cycles of charge, discharge, and recharged over and over without getting that dreaded memory thing..... At the 2yrs or little more mark.... for replacement due to just age of the battery's life cycle. just my opinion. I am on my 4th laptop with each being in service around 4yrs .... and I end up usually replacing the bat around the 3 yr for each one where they just hold a charge anymore.

I just bought a new battery when mine stopped losing its charge. Everyone is quick to offer "tips" but I just found them not too effective. I bought my laptop battery from and it works great, plus it was really affordable. Worth a browse for sure.
