What battery for Acer Aspire 5630 has longer charge?
Min asked:
I’m thinking of buying a new battery for my laptop because I just recently added another gb of ram which shorts the life of my battery and I want another one as a backup. Can anyone tell me which one has a long charge for oh maybe more than 3-4 hours if I use high performance, etc battery settings?

More ram will not shorten the life of the runtime. In fact it should increase it.
Good luck finding an battery for a PC that will last more than 2hrs. Windows initiates a write to the HD every 4-5 seconds which keeps the HD in constant spin. More ram=Less writing but it still does it.
Either way… 6 cell batterys are 2hrs, 9 cells are 3hrs, 12 cells are 4hrs.
Turn off your wireless, bluetooth, don’t use your optical, turn the brightness down all the way, turn off the paging file and you might get an extra hour.

HOW TO CHOOSE LAPTOP BATTERY- realize from Parameter to Cell.
you can see this article
Therefore it is very important that how to choose laptop battery.
As a consumer, the simplest and directviewing method of choose laptop battery is see the quantity of cell.
Mainstream laptops standard on 8 cell , 6 cell or 4cell lithium ion battery.the 4 cell battery usual be used in slimmest laptop.
The more the quantity of the cell, the more long it is Battery life.
when choose laptop battery, some person pay more attention to the “mAh”. mAh is a unit of cell capacity. We can see the sign on Laptop battery says “6 cell 4400mAh” or “4 cell 2200mAh”, making it easy to believe that the Battery life depending on the cell capacity, but this is not the case.
Now we need realize another parameter : watt hour.(Wh)
relation between Wh with mAh.
Wh÷V×1000=mAh
The important parameters of bettery are Voltage, watt-hour, mAh.
for example: the battery life is diffenrent when an 4800mAh lithium-ion batteries work at different voltage(10.8V, 11.1V)
This difference stem from the change of watt hour.
4800÷1000×10.8=51.84（Wh）
4800÷1000×11.1=53.28（Wh）
4800mAh lithium-ion battery work at 11.1V have more advantages than work at 10.8v.
