uses nickel oxide in its positive electrode (cathode), a cadmium compound in its negative electrode (anode), and potassium hydroxide solution in its electrolyte. This is rechargeable, so you can use it over and over.
NiCd batteries typically last longer, in terms of number of charge/discharge cycles, than other rechargeable batteries such as lead/acid batteries.
A battery charger is a device used to put energy into a secondary cell or (rechargeable) battery by forcing an electric current through it.
The purchase of a charger is cheap and simple. They are so foolproof these days that even if you get the polarity wrong, you won't get a spark, and the charger will not be damaged.
a high energy density, 3.6V battery that is widely used in the portable equipment market. It uses lithium metallic oxide in its positive electrode (cathode) and carbon material in its negative electrode (anode), and the lithium ions inside the battery transfer between the positive electrode and the negative electrode during charge or discharge.
- High voltage of 3.6V lets you cut down on the number of batteries you use.
- High energy density minimizes battery size and weight, making it perfect for use in small portable equipment.
- No metallic lithium is used so charging and discharging are very safe.
- No memory accumulation so it provides a full charge every time.
- The outer casing in square type batteries is an aluminum alloy, so overall battery weight is lower.
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.

UPS Maintenance Service
Don't be left POWERLESS!
The UPS systems all take stand by battery power starting at 8 to 650 kva on line low frequency -to galvanic isolated ups systems. Larger systems carry 100 amp batteries. Most UPS systems have 12 batteries to make up 144 volts which under load will be comparable to 115 ac volts (typical wall socket). The batteries required for UPS are extremely varied, at CHRISMAR BATTERY LTD. we can service or supply any battery style that you require. Has your UPS had it's check up lately? Don't get caught with your systems down. Let us analyze your UPS to ensure that it's ready when it's needed.
Why Your Battery Needs Care
One area that is regularly neglected by people who use boats, cars, motorcycles, or indeed any manner of electronic equipment is the battery. If you need a battery for your TV remote control and don't have one, no big deal. But if you are 5 miles offshore, or some distance from home, and the battery fails in your boat or car, you could be in serious trouble. It would be obvious that out at sea presents a potentially more serious situation, but providing your battery with optimum charging and a good state of health couldn't be simpler.
