depends how strong and how many amps are still in battery and the each radio is different
That depends on the load. If the load is 1 milli-amp, the battery would last for 4400 hours. If the load is 8800 milli-amps, the battery would last for 1/2 hour. (in a perfect world, discounting electrical inefficiencies)
As long as the battery is the same overall size and the terminals are in the same location, then yes.
How long a battery will provide power depends on the rate at which electricity is drawn from the battery. The slower the power is removed, the longer it will last, and the faster it is removed, the shorter the duration. The "Mah" stands for: "Milli" means one thousandth, the "a" stands for Amps, and the "h" stands for hours. The 4500 Mah rating means that the battery is capable of delivering 4,500 Milliamps [or 4.5 Amps] for one hour. 4,500 Milliamps is the same as 4.5 Amps. Since how long a battery can deliver power depends on the withdrawal rate, here are some examples of delivery times in relation to some withdrawal [discharge] rates: * The 4500 Mah battery will provide 4,500 Milliamps [4.5 Amps] for one hour, or * 9,000 Milliamps [9 Amps] for one half hour, or * 18,000 Milliamps [18 Amps] for one quarter of an hour [15 minutes], or * Going in the opposite direction, at a discharge rate of only one [1] Milliamp per hour, then it will last for 4,500 hours!
Car batteries should last for a few years at least. There are factors that affect battery life such as alternator, humidity/salinity and quality of battery. Also using a battery with the proper amount of cold cranking amps is important as well. Check with your local retailer to find the best battery for your vehicle.
It depends on the laptop. If you have a small laptop like an EEE PC you could see 10-12 hours. If you have a mid-range laptop with a power-efficient processor you could get 6-8, and if you have it in a gaming rig laptop you may see around 3 hours.
Calculating Battery LifeYou should do your own homework, but I'll give you part of the answer to get you started, and you can do your own math. Divide the Amp-hour capacity of the battery [22] by the current draw in Amps [65 mA = 0.065 Amps]. That will give you the number of hours the battery will last. If you want to convert that to days, divide again by 24 [the number of hour in day].
It seems a 2600mAh battery lasts up to 80-100% more than a regular battery. This can mean it can be used approximately 15 hours or more.
It takes between 8 and 12 hours to charge a 12 volt battery at 2 amps. The actual time will depending on how much charge is in the battery initially.
Yes, as long as it is the correct size battery with the correct cold cranking amps.
8 hours
A fully charged good battery is designed to last 21 days in the newer vehicles How old is your battery?Check parasytic load on vehicle should be .07 amps
