How many volts and how many milliAmps? Don't want to burn out battery.

It is specifically for a Kindle. I gave to my granddaughter so I can't look at it to check output.

Yes. 6800mAh is 6.8 Ampere-hours at 12V. It should therefore be able to run at 1.5 amperes for more than four hours. I wouldn't run it much higher than that, though. 1.5 Amps is a lot of current for that little battery. I routinely run a 3800mAh unit (=3.8 Ampere-hour) at 0.9 Amp for over four hours.

Batteries are rated in mAh or milliAmpHours. AA batteries are normally 1500 mAh. This means you can draw 1500mA for an hour or 1.5 Amps for an hour (just removing the milli by multiplying by 1000).If you are drawing 2Amps this would last for 1.5Ah/2A this leaves you with 1.5/2 hours or .75 hours or 45 minutes.

The output is listed as: 2×USB 5V 2100mA, DC 9V/12V 2000mA. mAh is commonly used to describe the total amount of energy a battery can store at one time, so that is not related to a particular voltage. The fact that it is 10000 mAh just means you can change your device more time than with a external battery of less capacity.

Sorry, I don't know enough about milliamperes and the science of charging. I used it for numerous different proprietary camera batteries, an emergency radio as well as aa and aaa batteries.

Dude just charge it until the meter reads full it will not hurt your batteries. Joe

Yes! mAh is Milli-Amp hours.A battery rated for more mAh will power a phone for a longer amount of time, given the same usage pattern.

Only if it is12v led. The battery is pretty stout, but you only have 12 ah (amps per hour). With that said you will have to calculate the rate it will drain the battery.DC watts to amps calculation formulaThe current I in amps (A) is equal to the power P in watts (W), divided by the voltage V in volts (V):I(A) = P(W) / V(V)So amps are equal to watts divided by volts.amp = watt / volt12 = 144w / 12vMax run time on a perfect charge/battery 12 hrs.

This is a 6 cell battery with 1500mamphr of power. My laptop is used as a desk top so I don't stress battery as it is normally plugged in. However when old battery failed I had to remove it to avoid error msgs. This was very low priced solution for my needs.

I can't give you a precise answer, but I have always had enough juice in the battery to do what I need. I use this computer mostly for power point presentations that last a couple of hours. I always make sure the battery is charged up before I do the presentation.

OK, this is how I think of it. Watts=amps x volts. So from their description, 7 watts = amps x 12 volts. This makes 7 / 12 = amps putting it at .58 amps. I checked the back of the panel. It says 467 mA. Google says 467 milliamperes = 0.467 amperes. Kinda close? Hope this helps.

No, they are 1.2 Volt, 2850 mah ... I use these in my digital camera and they are the most awesome batteries I have ever used!

The batteries are 18V and rated at 54 Watt Hours. So in terms of mAh this would be 3000mAh or 3.0 Ah. However, comparing this to a AA battery that has 2800 mAh (a common size) at 1.5 volts is not very meaningful. Be sure to compare batteries that have the same voltage output.

It requires a DC9V-DC12V 250mA. So you have a range of volts to work with, but a set milliamp. Good luck. Have fun.

Here are the specs listed on the battery: 1.2V; Typ. 2,000mAh; Min. 1,900 mAhI hope this helps.

Question 1: It's the charging rate of the battery. "maH" means milli-Amp per hour. A "milli-Amp" is 1000th of an Ampere. Q2: Yes. I have charged 4-10,000 maH batteries together on this unit. And, so far, so good. I buy very few alkaline batteries any more. If space permits, or isn't an issue, I always carry a charger when travelling.

These are 12 volt 35ah batteries. (Volts x amps = watts) So 12vx35ah = 420 watts max capacity per battery and 840w for the pair. If you want your batteries to last, do not discharge below 50% -- Therefore, with (2) batteries at 420 watts each, there is a usable 420w if you want your batteries to last a reasonable amount of time (500 cycles) - Your application may already have a low voltage limiter which won't let you drain below 11.9-12 volts which is about 50%
