How long a 3v battery well last?
Several years, in the refrigerator if there's no load placed on it. If you're actually USING the battery, then its lifetime will depend on the size of the battery and how much current you're drawing from it.
What does tire load rating mean?
how much weight you can put on it.
How do you know how much amp you have in your battery?
this problem can be fixed by refferring to mannual of that battery and also can calculated by another way use a load 10 watt on your battery and measure the current flowing through it and note the current time after that when your battery discharge multiply the measured current from hour(during discharge period). this result is your amp-h rating of battery.
How many hours a 2600mhp cell battery last?
It depends on how much drain is placed on the battery !
Why do you load test a battery to half the cca rating?
CCA is a discharge for thirty seconds at the rated CCA in Amps normally done in a laboratory at -18 Deg C after a minimum duration of 16 hours in freezer with the battery condition charged at 100% prior to placing in the freezer. This is not practical in a service centre but portable discharge-units are available which can load the battery at half the CCA rate for 15 seconds without too much heat being generated giving a useful load voltage result >9.6 Volts
What does the watts rating on a stereo speaker mean?
how much energy it draws from your outlet or car battery.
How long will a battery with a 30 ampere hour rating supply a 240 Watt load?
The Ampere-Hour rating tells you how much energy can be extracted from a given battery. For our 30AH battery, you could draw 1A for 30 hours, 2A for 15 hours, 3A for 10 hours, 30A for 1 hour, or any combination where Amps X hours = 30, within reason. Are you talking about a battery supplying a load directly, like a 12V battery supplying a 240W, 12V heater? Or do you mean a battery running an inverter supplying a 120V, 240W load? For the direct load, first calculate Amps drawn by the load. Amps = Watts / Volts. Then divide the A/H rating of the battery by the load Amps. Example: * 240W, 12V heater * Amps = 240 / 12 = 20A * Time = 30AH / 20A = 1.5 hours (90 minutes) For a load run by invertor, you just divide the Watts needed by the efficiency of the invertor. The efficiency rating is almost always found on the nameplate or in the manual. Most modern invertors are in the range of 90% - 96%. Example: * Same as above, except load is 120V, 240W heater run through a 90% efficient invertor. * Watts drawn from battery = 240 / 0.9 = 267 W * Amps = 267 / 12 = 22.2A * Time = 30AH / 22.2A = 1.35 hours (81 minutes) One factor to consider: The Amp-Hour rating of a battery is only valid up to about 10% of capacity current draw. So, a 30AH battery is only 30AH for loads up to 3A. At very high loads, the available AH from a battery decreases. This derating varies with size and manufacturer, but don't count on getting every minute of operation from our example above, because our current draw is much higher than 3A. In this case we might only have 25AH or so to play with.
How much electricity can a 12 volts battery produce?
A 12 volt battery supply a 12 VDC potential to a 12 VDC load.
How much time backup An 20 amh battery with 15 watt load?
Nominally(11/3) times (the battery voltage) hours.
How much gas does a f250 truck need?
Depends on the engine and the work load being placed on the truck.
Can I battery 670mAh instead 760mAh?
If the voltage is the same, the batteries are most likely interchangeable. The "mAh" rating simply tells you how much energy the battery can store - so, a battery with more mAh will last longer.
Can a narrow aisle lift truck with a 3000lb capacity at a 24in load center safely lift 3000lb at 36 inches?
No... that's the max load rating at a 50% lower height than the one you're talking about going to... going that much higher will decrease the weight rating dramatically.
