mAh/Ah (milliampere-hour/Ampere Hour)
This is the Capacity usually expressed in mAh /Ah meaning milli-Ampere hours/Ampere hours. This is basically the amount of current the battery will give multiplied by the number of hours that it will give it for, so a bigger number means that the battery will last longer in the device you are using it for.
Think of the battery like a bucket of water, mAh or ah rating is how much water the bucket can hold the bigger the bucket (mAh/Ah ratting) the more water it can hold.(current)
My New battery Isn't Charging. What's the Deal?
New batteries are shipped in a discharged condition and must be charged before use. We generally recommend an overnight charge (approximately twelve hours). Refer to your user's manual for charging instructions. Rechargeable batteries should be cycled - fully charged and then fully discharged - 2 to 4 times initially to allow them to reach their full capacity. (Note: it is perfectly normal for a battery to become warm to the touch during charging and discharging).
New batteries are hard for your device to charge; they have never been fully charged and are therefore "unformed". Sometimes your device's charger will stop charging a new battery before it is fully charged. If this happens, simply remove the battery from your device and then re-insert it. The charge cycle should begin again. This may happen several times during your first battery charge. Don't worry; it's perfectly normal.
