Stay charged with Lithium Ion rechargeable batteries
Lithium Ion (Li-Ion) rechargeable batteries are perhaps the most effective way of storing electrical power for small, portable electronic devices. Best known as the high capacity batteries in most laptops, camcorders, smartphones and other cordless devices in Australia today, lithium-ion batteries actually come in all shapes and sizes and can power just about anything.
Lithium-Ion battery chargers
Of course, smartphones, laptops, tablets and similar items come with a built-in lithium-ion battery charger, so that you need only connect a suitable charging cable to a wall socket or a live USB port to fill up your hungry device.
Li-ion rechargeable batteries for everyday items such as remotes, cameras and children's toys are recharged by an external charger that you can plug into any household socket. Rechargeable AA batteries are used most often, closely followed by AAA, but there is a huge number of different Li-ion batteries to power different things. Laptop batteries are longer more heavy-duty batteries able to hold considerably more charge than their smaller counterparts, and the slimline, rectangular mobile phone Li-Ion batteries are lighter for added portability.
A lithium-ion rechargeable battery will last a long time over many recharge cycles. To keep your battery lasting longer, do not leave the device plugged in when the battery is full, let it drain naturally instead. Overcharging a battery can cause it to lose power quicker, eventually leading to a new battery being needed.
Understanding battery rating
To make sure you are buying the right battery for your device, look at its power rating. Your battery must match the devices required voltage as well as its current draw (in amps or milliamps). Lithium-Ion Batteries are available in almost every standard battery size. Common sizes include AA, AAA, c, D, 9v, 18650, CR123A and 12250, as well as many others. Popular brands include Panasonic, Sanyo, Energizer, and others.
