Yes - the only difference is the storage capacity (4400mAh against 4000mAh) - it will take slightly longer to re-charge.
a car battery last for about 3-5 years
As long as the battery is kept charged then it should last 3-5 years.
a panasonic triple a battery last about 4 hours nonstop.
about a year.
8hrs
Forever.
That depends on how many, and how long you puff on it. My ZMax with 2 800mah (1600mah) batteries last me 2 days; and I was a heavy smoker before I changed over. I run 2.8ohm heads at 4.5v to 4.7v (7 to 8 watts). My wife and I looked into various models and wanted to have something we could use over time without a huge investment. It's good to read about all the options regarding battery size and how long they last. We've been pleased with the V2Cig brand, since trying them and a couple of others. I was thinking about the 135mm 280 mAh size battery that says it's good for 300 puffs. It seemed to last a long time without needing to be recharged. My wife was fine with the 100/190 version. Good info up here. We like to compare when we shop. Thanks.
No the battery is built in but should last a long time.
A Sanyo phone battery last just about as long as any other battery. Most batteries are manufactured by just a few different manufacturers, and then rebranded.
4400 mAh means that the battery can produce 4400 mA for one hour. Similarly, 7200 mAh means 7200 mA for one hour. In reality, these specifications are for a eight-hour rating, meaning that the 4400 mAh battery can produce 550 mA for eight hours but, comparatively, you can just ratio the ratings, so the 7200 mAh battery will last 60% longer than the 4400 mAh battery There's more to it than that, however, as you need to know that the laptop is designed to use either battery, otherwise the camparison is meaningless.
If you divide the 5000 mAh by the current used (in mA), you will get the number of hours the battery will last.
