The Casio NP-20 rechargeable lithium-ion battery is designed for use in several Casio digital camera and camcorder models. As with all rechargeable batteries, your Casio device can experience problems when attempting to recharge the NP-20, but you can take several steps to deal with these problems, which require little tech know-how.
Cable
Most digital cameras and camcorders include a cable that connects to a standard power socket or converter for the purpose of recharging the device's battery. Over time, the cable can become damaged or non-functional, especially if you use it frequently. If your Casio NP-20 battery is not charging properly when plugged into a power outlet, the problem can be caused by a damaged cable. Checking the cable for signs of wear and tear, especially around the parts where the wire links to the connectors, can help you identify whether the cable is damaged. If the cable is damaged, replacing it will likely fix the situation.
Power Source
Occasionally, a rechargeable battery can fail to accept a charge because of the power source's ability to transfer electricity. If your wall outlet is not properly ground or you have recently experienced a power surge or outage, the socket might have lost its ability to conduct power. Plugging your Casio camera or camcorder into another power outlet can help you identify if this is the reason why you are unable to recharge the NP-20 battery. If you're using a power adapter, such as one that's designed to charge your camera in a car, the adapter might be damaged, in which case you should replace the adapter.
Battery Life
With each successive recharge, lithium-ion batteries lose a fraction of their power capacity. Eventually, the NP-20 will lose all of its ability to hold energy and will not respond when placed into the camera or camcorder for recharging. In these situations, replacing the battery with a new one is all that you can do. However, you can prolong the battery's life by employing several energy-saving techniques, including turning the camera off when it's not in use and refraining from recharging it until the device's battery indicator is less than half full.
Considerations
Although the Casio NP-20 lithium-ion battery is designed for use in Casio cameras and camcorders, you can also use batteries manufactured by other companies, such as Delkin. Using an extended-life battery, whether manufactured by Casio or one of its competitors, can help you get a longer battery life for your camera. Most digital cameras and camcorders are able to function while using a traditional power source, such as a wall outlet, so using this feature can help you use the device in a pinch when its battery is failing to charge.
