mAh is short for milli ampere hours. It's a measure of the capacity of the battery. Comparable to the size of the fuel tank of a car. So a 6500 mAh battery is almost ten times the size of a 700 mAh battery.

If specification is 700mAH batteries can you use 850mAH batteries?
Sizing BatteriesIF there is room [physically] for an 850mAH battery to fit instead of a 700mAH battery, and it is the same type of battery [Lead-Acid, Ni-Cad, Gel Cell, etc.] then yes you can make the substitution. The 850mAH battery is just electrically slightly larger than the 700mAH battery. The numerical designations for the two battery examples you give in your question mean that the first battery will deliver 700 milliamps [700/1000th of an Amp] for a period of one hour. The same is true for the second battery except that it will delivery slightly more current[850mA] for one hour, or the same 700mAH rate for a slightly longer time.
How much to charge 700mah 4.8v nicd battery?
Well i charge mine for 2 hours. For me the battery was in an airsoft gun magazine when i was younger. I remember that i over charged it and it broke so i wouldnt go over 2 hours. hope that helps.
How much does a Razr battery cost?
A working, reasonably new 700mAH battery for the Razr can be easily found on sites like amazon.com for under 5 bucks. Watch out for batteries that are extremely cheap, as they might actually be used or counterfeit which means that certain safety and reliability standards may not be met.
Use a 900 mAh battery vs a 790 mAh battery for Canon SD550?
The 900mAh battery will work fine - it just gives your phone an extended time between charges. I've replaced the original 700mAh battery in my phone for a 950mAh one - and get about 40% extra talk & standby times.
How much longer will 700mAh last compared to 650mAh?
The simple answer is 700/650 =1.08, so that makes it less than 10% longer. In practice, if we are looking at rechargeable batteries, there's likely to be more variation between individual batteries - different ways of measuring capacity, different usage history, chargers, etc - than that. You'd be unlikely to pick the difference. A milliampere hour specification shows how much current can be delivered to a load in a given period. So if you had a 10 mA hr battery and a load that used 1 mA the battery would last 10 hours.
If a device is running on a 700mAh 9.6v battery what is the effect to this device if a battery with 2500mAh 9.6 v is used instead?
As both batteries have exactly the same output voltage 9.6 Volts, there will be no effect to the device. The bigger battery just lasts for a longer period of time before it has to be re-charged. You can get an approximate idea of how much longer by doing some simple calculations: If the device takes a current of 100 mA, * it would run for 700 /100 = 7 hours on the 700 mAh battery * it would run 2500/100 = 25 hours on the 2500 mAh battery.
How long for first charge Ni-Cd 7.2V 700mah?
Depends on the charging rate, in Amps, of your charger. Very simply, if the charger current is rated at 450mA, then a 450mAh battery would require 1 hour to charge. Take the batter rating (450mAh) divided by the charger current rating (450mA), which equals 1 hour. If the charger rating is only 100mA, then it would take 4.5 hours to charge the same battery.
Can you replace the battery ni mh 750 mAh for a cordless phone with the battery with the lower mAh eg 550?
the 'mAh' designation refers to milliamphours. So 10 mAh could mean 10 milliamps delivered over a period of 1 hour, or 1 milliamp delivered over a period of 10 hours.You should expect the 1500 mAh battery to last 2.5 times as long under the same load conditions as the 600 mAh battery.I do not know the current load specifications for a cordless phone, but to give an example, let's suppose the phone draws 300 mA while talking.So the 600 mAh battery: 600 mAh / 300 mA = 2 hours.and the 1500 mAh battery: 1500 mAh / 300 mA = 5 hours (2.5 times as long)
