Which is better the 6600 mah or 4400 mah li-ion battery for a laptop?

It depends on the voltage. WH = Watt Henry, mAH = milliamp Henry, watts = amps * volts and milliamps= 1000 * amps. Thus the conversion is:
mAH = 1000 * WH / V,
where V is the voltage.
I'm looking at the battery for my Dell Studio and it's rated 85WH and 11.1V. So it's 1000 * 85 / 11.1 = 7658 mAH, so in this case 85WH is better than 6600 maH.
If we solve 1000 * 85 / V = 6600, we get V = 12.9. When converting from WH, the bigger the voltage the lower the mAH. So for voltages bigger than 12.9 V, 6600mAH is better than 85WH.
Hope this helps.

Which is better 2550 mAh or 4400 mAh for a mini laptop?
It's not a question about "better", it's about what's most important to you - weight/size or runtime. The 4400 mAh battery will let you run the laptop on battery longer, but will probably also make it a little bit bigger/heavier. More to carry around. The 2550 mAh will last a bit shorter, but will keep the laptop smaller and lighter. You have to decide what's important to you.
What is the difference between 4400mAh and 6600mAh on a laptop battery?
mAh is a rating of a battery's capacity. A 4400 mAh battery is capable of delivering 4.4 amps of current for one hour. A 6600 mAh battery is capable of delivering 6.6 amps for one hour. That is not to say that both batteries will only last for one hour, since the laptop will probably draw less current than that. The important thing to notice is that the 6600 mAh battery has 50% more capacity than the 4400 mAh battery. If battery life is your #1 priority, the larger battery would be a good choice. However, it may be larger and heavier than the 4400 mAh battery. If a small, lightweight laptop is #1 priority, the smaller battery might be better. Also, if the laptop will not be unplugged, on the go all the time, the smaller battery might be a better choice due to it being cheaper. As all things engineering, there are compromises to be made.
Can 7800 mah laptop battery replace 4400 mah?
Yes, but only if the power supply design of the laptop allows it, because the charge controls are dependent on the battery. Ask the manufacturer first.
What is 4800mAh?
A battery rating of 4400 mAh means that the battery can nominally produce 550 mA for 8 hours. Even though it would seem that the battery will produce 4400 mA for 1 hour, it will not actually last that long. By convention, current-time ratings on batteries are normalized to an 8 hour rating.
Can you use a 6600 mah battery in a 4400 mah laptop?
Most laptops come with two different battery options, one that's small and light, and one that's bigger and heavier and offering more runtime. If the bigger battery is listed as compatible with your laptop(there's no standards when it comes to battery compartments), then you're good to go.
Can you replace 4200 mah with a 4400 mah?
Yes, this is possible. The digits refer to the battery life as measures in milliamperehours (mAh). If "x" indicates the old battery and "y" indicates the new, then the equation (60/4200)*4400 will indicate how much longer the battery will last.
What is the difference between 4400mAh 48 Wh and 6600mAh 71 Wh on a laptop battery?
The difference is an increased battery capacity (hence longer runtime). A batteries capacity is measured in Ah (or mAh) and is the product (ie multiplied together) of the current being drawn and the time the current is drawn for. Thus a 4800 mAh battery can supply a 2A current for 2.4 hours (ie 4800/2000) while a 4400 mAh battery can only supply a 2A current for 2.2 hours.

What is 2 percent of 4400?
2% of 4400 = 2% * 4400 = 0.02 * 4400 = 88
4400 mA laptop battery how many minutes will it last?
1-6 hours if its a 6 cell, if you want one slightly better get a 9. A tip, dimming screen as much as possible conserves life, also if you use ac, remove battery. Although they can't overcharge this does kill them faster. Some laptops are adding a feature to keep them less than fully charged on AC power since you only get so many cycles but most don't have the safeguard yet.
