Top of the Line 7200 mAh DELL Inspiron 1501 Battery

85 wHr: What does this mean?  One watt-hour is the amount of electrical energy equivalent to a one-watt load drawing power for one hour.  For example, a 60-watt light bulb uses 60 watt-hours of energy every hour.  In terms of laptop batteries, these batteries can handle up to 85 watt-hours of energy drain per hour. This doesn't mean that your laptop will actually consume that much in an hour, but that battery can handle that much, if necessary.  Again the net result is 4 to 5 hours of power without plugging in.

Energy Savings : Most importantly, these highest capacity 7200 mAh batteries will save you money on your utility bill.  Here is how:   

Using the battery as long as you can during the day, and then allowing the battery to charge at night as you sleep, you will be taking advantage of much cheaper power rates.  This is a practice we have recently begun using and have begun to see the cost savings.   In most areas, this overnight rate is 3 to 4 times cheaper than power used during the daylight hours.  This 7200 mAH battery delivers the longest computing time off the grid. when you use your laptop and have it running on battery power, automatically the laptop adjusts to run in a power saving mode (e.g. slightly dimming the lcd, and slowing the cpu speed – still powerful enough for 99 percent of the computing most of us do).  Finally the best way to save money and power is to remove your battery when it is fully charged, modern laptop batteries can hold their full charge for months. Using your battery until it is dead then recharging it will wear it out much more quickly, which, as we know, can be very expensive to replace.  Another energy saving tip:  Your laptop’s DVD drive and LCD brightness require the most electricity.
