The Flip UltraHD camcorder is a line of compact video recorders from Flip Video. It is the only line of camcorders from Flip that can use external battery packs. All other Flip camcorder models are powered by internal, non-removable battery packs. Both the Flip UltraHD 4GB and 8GB models can use a variety of battery sources, including conventional batteries, rechargeable batteries and Flip's custom rechargeable battery packs.
Battery Sizes
The Flip UltraHD 4GB model camcorder includes two AA batteries in the box, while the Flip Ultra HD 8GB model comes with its own rechargeable Lithium-ion battery pack as an alternative to three conventional AAA batteries. The Lithium-on rechargeable battery pack is the same size as three conventional AAA batteries. You can use conventional batteries in either camera at any time, although the rechargeable battery packs are more environmentally friendly.
Compatibility
As an alternative to the Flip rechargeable battery packs, you can use any two conventional AA batteries in the Flip UltraHD 4GB, and any three conventional AAA batteries in the Flip UltraHD 8GB. You can also use any two rechargeable NiMH AA batteries in the 4GB camcorder, or any three AAA-sized Li-ion batteries in the 8GB model. You must recharge any rechargeable batteries in their own external charger.
Rechargeable Battery Packs
Both models of the Flip UltraHD have rechargeable battery packs available as accessories. Flip does not include the rechargeable battery pack with the 4GB, but you can purchase a rechargeable nickel-metal hydride battery as an additional accessory. NiMH batteries can hold several times the charge of a conventional battery, so it remains charged for up to two and half hours. The 8GB model's Lithium-ion battery can hold a charge for up to two hours.
Recharging Batteries
You can recharge the rechargeable battery packs from Flip by plugging them into any USB port of a plugged-in computer or other device. The length of time required to fully recharge the battery packs depends upon the age of the battery and the amount of use. You cannot recharge other rechargeable batteries while they're in the Flip camera. The USB recharger only works with the custom rechargeable battery packs from Flip.
