How do I identify my battery
The first information to provide would be the make and model of the equipment that you require the battery for e.g. Nikon D5000, or Canon PowerShot S20. There is also usually a label on the battery, and some of this information on the label will help our sales team to identify your battery quickly. This information includes the voltage of the battery pack (note: this is not the same as the voltage on the power supply), the capacity of the battery pack and the chemical construction of the battery pack e.g. Li-ion, Ni-MH or Ni-Cd. This information can be used to ensure the information you have provided matches the information we have about your battery. Many battery packs also have part numbers on the label; this can sometimes be used to help identify the battery. We would suggest that it is best to have all this information written down or close to hand before you call our sales team. This will help us deal with your call in an efficient manner.
What is the difference between Ni-Cd, Ni-MH, and Li-ion
Li-ion (Lithium Ion): This is one of the newest cell types available. It is also the lightest battery type currently available on a commercial basis and can provide more power than the other main cell types. There are no known problems of memory effect with this battery type and it is the easiest battery type to care for. The downside of this battery is that it has the highest engineering costs and therefore the price is usually considerably higher than other cell types.
Ni-MH (Nickel Metal Hydride): This cell type is the most common cell type currently available for laptop computers, (although Li-ion is rapidly becoming the most popular) This battery type is relatively cheap to manufacture and therefore tends to be cheaper than Li-ion. This cell type is prone to 'memory effect' so it is important to take good care of your Ni-MH battery to ensure that you obtain the best runtimes.
Ni-Cd (Nickel Cadmium): This is one of the oldest cell types and is generally only found in older laptops. The main pro for this cell type is its ability to handle higher loads, and therefore is more commonly found in portable power tools or devices that need a lot of power to work efficiently. The main downside of this cell type is that it is notorious for suffering with memory effect so good care must be taken with this battery to ensure most effective use of battery.
Always in a word, Li-ion batteries can be recharged, but Ni-MH and Ni-Cd generally can't be recharged.
How long does a battery life
IThe life of a rechargeable battery operating under normal conditions is generally between 500 to 800 charge-discharge cycles. This translates into one and a half to three years of battery life for the average user. As your rechargeable battery begins to die, you will notice a decline in the running time of the battery. When your two hour battery is only supplying you with an hour's worth of use, it's time for a new one.
Battery Usage Tips
- New battery pack must be fully charged before use.
- New battery pack needs to be fully charged and discharged (cycled) a few times before it can condition to full capacity.
- Rechargeable batteries undergo self-discharging when left unused. Always store a battery pack in a fully charged staged for storage.
- Fully drain and fully recharged your battery pack every few months.
- Turn down the LCD brightness of your portable device.
- Use built-in power management on your portable device.
- Turn off LCD or other unnecessary accessories when not in used.
- Set screen saver blank to 1 to 2 minutes of your notebook
- Add more RAM if you have extra RAM expansion slot, it will reduce the usage of hard drive and it is power exhaustive.
- Close unused software in your notebook.
- Remove unused PC Cards or USB devices from your notebook.
- Don't watch DVD or play graphics intensive video games.
- Don't short circuit terminal or store your battery pack with metal parts.
- Don't drop or mutilate the battery pack.
- Don't expose to moisture or water.
- It is normal to get warm when charging or normal use. If it is getting too hot, there may be a problem with the device and qualified personnel should check it.
