There are two types of players: with batteries and without batteries. Most players except headrest DVD players are equipped with batteries. The player's battery can be charged. There are many types of rechargeable batteries, such as lithium ion (Li-ion), nickel-cadmium (Ni-Cd), nickel-metal hydride (Ni-MH) and lead acid.
Lithium-ion batteries are one of the most popular types of rechargeable batteries. Lithium-ion batteries have high energy density, little or no memory effect, and low self-discharge, making them safer and more resistant to electricity. Also, lithium ion batteries offer the best light weight. They are therefore also used in aerospace technology and in the military. Now most players use lithium ion batteries, AutoJoy too.
The capacity of the usual lithium-ion batteries in the player is around 1400mAh to 5000mAh. You can support the player for several hours after fully charging. It takes at least a few hours to fully charge the batteries. Usually the capacity is larger, the player can run for more time and the charging time also takes longer.
AutoJoy Players can run for 5 to 7 hours after a single full charge.
