-Urgent- Need answer and Acer VS Asus

battery lifespan doesnt decay so fast you know, you'd start noticing the decay at about a year with a mediocre handling, so a careful handling should leave you with a healthy battery for a longer period.
as far as i've heard of laptop batteries, people tend to ignore them and just use it as is, they don't even notice the damage they've done until years have passed.
at worst you'd lose like 10% of the current capacity per 2months, do note that its "current capacity" which means the decay lessens as the total capacity decreases, otherwise small capacity batteries made of the same battery type would lose all of it's charge in a few uses, but it doesn't.
although if i remember correctly the rate isnt by time, but by charge and discharge cycles.

fuhh, thats a relief...
but should i charge it full to leave it alone or charge about 80% to 90%?
i want my new laptop to hold up to 5 years...my old laptop is 3 years old and its battery is 1hours only (aspire 4741g)...

--- Quote ---Cell life
Charging forms deposits inside the electrolyte that inhibit ion transport. Over time, the cell's capacity diminishes. The increase in internal resistance reduces the cell's ability to deliver current. This problem is more pronounced in high-current applications. The decrease means that older batteries do not charge as much as new ones (charging time required decreases proportionally).
High charge levels and elevated temperatures (whether from charging or ambient air) hasten capacity loss.[48] Charging heat is caused by the carbon anode (typically replaced with lithium titanate which drastically reduces damage from charging, including expansion and other factors).[49]
A Standard (Cobalt) Li-ion cell that is full most of the time at 25 °C (77 °F) irreversibly loses approximately 20% capacity per year. Poor ventilation may increase temperatures, further shortening battery life. Loss rates vary by temperature: 6% loss at 0 °C (32 °F), 20% at 25 °C (77 °F), and 35% at 40 °C (104 °F). When stored at 40%–60% charge level, the capacity loss is reduced to 2%, 4%, and 15%, respectively.[50] In contrast, the calendar life of LiFePO4 cells is not affected by being kept at a high state of charge.[51]

try giving this a read.

I summarized this in the previous page....
Logiick:
It depends on what you want to do with the computers themselves.
ASUS is a better company, and it just makes better computers overall. But if you're looking for something simple and cheap, go with the Acer.
