Battery for portable applications SANYO Energy

Nickel-Cadmium (Ni-Cd) Batteries

It's rechargeable, so you can use it over and over; more than 500 times [Much more economical than dry cell batteries].
Discharge voltage remains stable even in conditions of high-rate discharge current [For equipment needing a high-rate discharge current, it's far more stable than other battery types].
Wide operating temperature range (-20°C to 60°C) [It operates especially well in low temperatures].
Performance doesn't deteriorate even after long-term storage [Full recovery of original performance levels after recharging].
Designed to withstand overcharge and overdischarge [Superior durability].
Produced using an ISO9000 certified quality control system [High quality and reliability].

Lithium-ion (Li-ion) Batteries

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.

Twicell Nickel-Metal Hydride (Ni-MH) Batteries

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.
