These batteries are cheap enough that you can keep a few around in the charger waiting for use. This battery charges quickly.
2400mAh is NOT the highest capacity for this type of battery, but the price is right.
This is not a "protected" battery - so if you use it in high-current situations such as to power a LASER, you are better off with a PROTECTED battery - see FAQS on www.AwesomeLasers.com
Good battery for general use. Charges fast & maintains charge a long time if stored in a cool place (do not refrigerate - it will leak if frozen).
