Twicell Nickel-Metal Hydride (Ni-MH) Batteries What is a Twicell Nickel-Metal Hydride Battery? It's a secondary battery which lasts more than twice as long as CADNICA batteries. Twicell uses hydrogen absorbing alloys in its negative electrode (anode) and nickel oxide in its positive electrode (cathode). Since its release, the first in the world in October 1990, the "Twicell" sealed Nickel-Metal Hydride battery has developed a strong reputation for high capacity, high performance and high quality. In November 1996, Sanyo was the first manufacturer in the world to achieve 300 million cells accumulatively.

The HR-4/3AU (3,500mAh) is a new battery (volumetric energy density: 300Wh/l), first marketed in May 1996, that well exceeds the volumetric energy density of lithium-ion batteries. Sanyo released another Twicell battery of even higher capacity (volumetric energy density: 340Wh/l) in the end of 1997. In addition, the new Twicell HR-4/3FAU(4,000mAh), released in September 1996, was specially designed for notebook computers and has the same diameter (18mm) as the lithium-ion UR18650 battery.

Features High volumetric energy density well exceeding that of Lithium-ion batteries (HR-4/3AU and HR-4/3FAU). Double capacity of standard CADNICA batteries. Can be used over and over (more than 500 times with a specific charger). 1.2-1.6 hour quick charge with a specific charger. Compatible with Nickel-Cadmium batteries (almost same discharge voltage). Produced under a ISO9002 certified quality control systems. Applications Notebook computers Cellular phones, PHS phones, telecommunications equipment Video cameras, digital still cameras, PDA Shavers, electric toothbrushes Various portable equipment

Has shorter cycles approx 500 than the Ni-Cad 800-1000 which explains the initial robust power. Chargers that are used to charge ni-cads are not suitable for ni-mh the reason being that ni-mh cells are not to be slow charged and overcharging a ni-mh is not as forgiving as a Ni-cad. We suggest charging a Ni-mh cell with a quick or fast charger.

We have tested both Ni-Cad and Ni-Mh cells and both are reliable especially for Portable lights and HD cameras etc...

Lithium-ion Cells? Well we do not think a reliable source of power DC should have to cost you $2,000 and up it is ridiculously expensive....

We offer reliable power at reasonable prices not budget busters...
