what does 1400mAh mean?
356616
That is the battery life. If your device draws 1.4 amps the battery will last one hour.
356617
It's the energy storage capability of the battery. The bigger the number means its able to run a given load for a greater length of time. Bigger is better.

The battery will provide 1400 milli ampere hours over it's lifetime. That's 1.4 ampere hours or 1.4 amps for 1 hour. If your light uses 10 milli amperes, the battery should last for 140 hours.

I have to admit that I bought the batteries for a tool for size. Forgot to check capacity but it looks like at least 1800 mah. Things have happened which has kept me from using the batteries. Sorry can't be more help. Price is right though

Hi Donna,The mAh (milli-amp-hour) is a measure of the capacity of the battery, so a 1,600 mAh battery is 1.6X larger in capacity than a 1,000 mAh battery. This has nothing to do with the voltage or amperage output. As long as you SD1300 IS takes the NB-6L Canon battery, this STK battery will work, and last longer between charges.Thanks,Jeff

3500 vs 1650mAh on the standard phone means longer between charging. Theoretically a little more than double the battery life. But I don't know the dimensions of the battery and whether it now becomes bulkier.

I think the higher number just means it stores more energy and should not harm the phone. I am using the 900 mAh battery in my older Panasonic phone and I believe the original battery was an 800 mAh.

Maybe, but it depends on the voltage requirement of the device. The battery is a 33Ah battery that can produce 15-20V depending on the settings. They claim 125 Wh. The formula to convert Wh to mAh is mAh = (Wh 1000) / V. So, we have 33,600 = (125 x 1000) / V. This gives us a V of about 3.72 V if their 125 Wh number is correct. On the other hand, if the 125 Wh number is the correct value at say 15V, that would mean that mAh = (125 x 1000)/15 or 8,333 mAh. So, as you can see, there's something screwy with their measurements.

If the 400 mAh battery fits physically it will last about 4/3 longer than the 300mAh battery. The suffix "mAh" is the designation used to signify current storing capacity of a small battery. The larger the number the better.

It could be labeled as 2AH. Smaller batteries such as these are traditionally labeled in mAh.

according to the image shown (you have to zoom in a bit) these units are rated at 860mAH

It is how much the battery can store in milliamperes-hours. A typical cell phone battery is 1500 mAh. Current is measured in amps. So for example, a battery rated at 2200 mAh can output 22 milliamperes for 100 hours.

mAh: Milliamp Hours.A unit for measuring electric power over time. mAh is commonly used to describe the total amount of energy a battery can store at one time.Wh: Watt hoursIt says how many watts of energy the battery takes per hour of use.

if you can smell the battery it probably is bad or your overcharging it.. How long you should charge your battery is totally dependant upon how many milliamps or mA it has. If it has 1400mA it will charge much faster than a battery with 2800mA. Now look at your converter, you will notice several things on the sticker that will be affixed to it. We are looking for the output rating on it specifically. It usually says something like "OUTPUT: DC 8.4v 300mA" but changes from brand to brand and model to model. See that 300mA on the charge? That's how many mA its charges per hour so if you have a 1500mA battery and a 300mA charger its just simple math from this point.So it will take 5 hours total to charge a completely dead/new battery to its full capacity. You simply divide the mA on the charge to the mA of your battery and you will get the time it should take to fully charge a completely drained battery. This does mean to set it and forget it though. In most cases your battery has already been charged once even if still new for quality control purposes so you really need to keep an eye on your battery still.

I don't know, I used this battery to power/charge my phone and electronics camping trips for over a week. It didn't powered my small refrigerator, which I think was 14amps,it would cut off after a 1 min.

I thought this had a 14 amp-hour battery and 200 CCA. But when I got it, the specifications for it actually said it had a 12 amp-hour battery and only 120 CCA.

I can say that it is 1600mAh when purchased from eForCity as the seller. The reviews seem to indicate that other sellers may be shipping 1200mAh.

It does say 1200mAh on the batteries I received, but I returned as they would not charge.
