Battery Information
The various battery types listed on the site have the following features and typical applications.
If you need more information please see our battery knowledge base
Alkaline
- Long-life batteries giving up to six times the life of ordinary zinc carbon batteries.
- Ideal for appliances demanding a high current drain when being used on an intermittent or continuous basis.
Zinc Chloride
- Designed to give significantly longer life than conventional zinc carbon batteries at around half the cost of the long-life alkaline batteries.
- Ideal for appliances demanding heavy or continuous use that require low to medium power.
Nickel Metal Hydride (NiMh)
Major features
- High Capacity - GP NiMH batteries have high energy density and deliver up to double the capacity of NiCd batteries of similar size.
- Superior high rate discharge characteristics - Up to 3C high rate discharge is possible
- Broad operating temperature range - (-20 C to 60 C)
- Quick charging capability - Rapid charge in about one hour.
- Long service life - Under different usage conditions, GP NiMH batteries can deliver 300-1000 charge/discharge cycles.
- Excellent overcharge endurance - GP NiMH batteries can be continuously charged at 0.1C rate for one year without leakage or deformation.
- Built-in saftely protection mechanism against misuse - A re-sealable safety vent is built in to relieve internal pressure in case of misuse. Polarity reversal and over discharge protection mechanisms are also incorporated in the cell.
- Absolutely no memory effect - Discharge is not required before charging.
- Environmentally friendlier - No cadmium, lead or mercury are added.
- Comprehensive range - GP NiMH batteries comprise of a comprehensive range of different cylindrical and prismatic sizes catering for a wide range of applications.
- High reliability - GP NiMH batteries are produced with the best available material and advanced technology, allowing them to perform with outstanding reliability.
- ISO 9001 accreditation - Received for design and manufacture of secondary and primary batteries in 1996.
Major Applications
- Communications - Cellular phones, cordless phones, transceivers.
- Information devices - Notebook computers, personal digital assistants(PDAs), portable facsimile machines.
- Audio and video devices - Digital video cameras, LCD TVs, portable DVD, VCD, MD and CD players.
- Emergency lighting
- Remote controls & security systems
- Other applications - Remote control toys, shavers, massagers, electric tooth brushes, handheld vacuum cleaners, power tools, handheld terminals, electrical bicycles etc.
Nickel Cadmium (NiCd)
Major Features
- Long service life - Depending on usage conditions, GP NiCd batteries can deliver 300 - 1000 charge / discharge cycles.
- Superior high rate discharge characteristics - Up to 2C high rate discharge is possible.
- Quick charging capability - Rapid charge in about one hour.
- Excellent overcharge performance - GP NiCd batteries can be continuously overcharged at O.1C rate for 28 days without leakage or deformation.
- Built-in safety features against misuse - Built-in chemical protection against polarity reversal or over discharge. A re-sealable safety vent is incorporated to relieve internal pressure in case of misuse.
- No memory effect - Unlike sintered type rechargeable cells, GP NiCd batteries produced with modern foam electrode technology do not exhibit memory effect.
- High reliability - GP NiCd batteries are manufactured with the best available material using state of the art technology allowing them to perform with outstanding reliability.
Major Applications
- Communications - Cellular phones, cordless phones, pager and transceivers.
- Information devices - Notebook computers, personal digital assistants(PDAs), portable facsimile machines.
- Audio and video devices - Digital video cameras, LCD TVs, portable DVD, VCD, MD and CD players.
- Emergency lighting
- Remote controls & security systems<
- Other applications - Remote control toys, shavers, massagers, electric tooth brushes, handheld vacuum cleaners, power tools, handheld terminals, electrical bicycles, memory back-up etc.
Rechargeable Alkaline
- Offers the benefits of standard Alkaline cells but with rechargeable capability.
- Also more beneficial than NiMH cells due to; 1.5v, initially fully charged
- Can be stored up to 7 years charged
- Can be charged 50 times (although a 500 times may be possible)
- N.B. These batteries can only be charged using an Alkaline Battery Charger.
Silver Oxide
- Silver oxide batteries have the most stable voltage characteristics among all types of button-type batteries, as well as delivering the highest performance
- Silver oxide batteries use silver oxide for the positive active material. The negative active material is zinc, and the electrolyte is potassium hydroxide
- Because of the use of these materials, the silver oxide batteries have a higher operating voltage and an extremely stable power supply. The nominal open-circuit voltage is 1.55 volts
- Silver oxide batteries are also far superior in heavy drain uses and suitable for the use in cameras and exposure meters.
Lithium Ion
- Compared with NiMH and NiCd batteries of the same sizes or weights, Lithium Ion batteries are designed to deliver the highest energy output<
- A single cell voltage is 3.7V, 3 times that of NiMH batteries. It means a simpler battery configuration and better space utilization for low cell voltages.
- Graphite type negative electrode has a steady discharge voltage essential for electronic equipment.
- It can be charged in about 1-2 hours.
- Lithim Ion batteries can be charged or discharged up to 300 - 1000 times under normal conditions
- No memory effect - Li Ion batteries can be recharged after partial discharge without experiencing the memory effect of NiCd batteries
- Most Lithium Ion batteries are desiigned and built with internal safety features to resist physical abuse and to prevent overcharge and over current.
- Li Ion batteries contain no toxic heavy metals, such as mercury, cadmium or lead.
