Do I need extra or backup batteries?

Probably you do. Batteries are arguably the most important portable electronic device accessory. For example, unlike traditional cameras, which can often go months without needing a battery replacement, some digital cameras can consume power at an alarming rate, providing no more than a few hours of continuous shooting time before the battery is drained. Other digital devices like PDA, laptop, etc have the same situation as well. Knowing how you intend to use your camera and what type of battery it needs is key to making an informed purchase. To our experience, 90% of portable electronic device users keep at least 1-2 extra or backup batteries, especially when traveling or having a heavy-duty outdoor job on the devices. Thus we suggest you be always prepare a few backup batteries in case that you really need to use the device when it happens to run out of power.


Why my new battery won't hold a charge?

1) Your battery might be loose. Please check the connection between the battery and the device to be sure the battery is securely attached. 2) Some devices come with multiple batteries. You may also want to try to charge an alternative battery in the device or charger. If you have already checked both of above and still had troubles to charge the battery, either your battery or your charger/device should have problems.


Why my new battery has a very short running time even "fully" charged?

New batteries are supplied in a totally uncharged state. To ensure maximum battery performance, a new battery (or battery that has not been used for several months) should be charged for at least 14 hours before use. When charging the battery for the first time, the device may indicate that charging is complete after just 10 or 15 minutes. This is a normal with rechargeable batteries. New batteries are hard for the device to charge; they have never been fully charged and not "broken in".To be completely and deeply charged, a new battery will require several full charge/discharge cycles in order to achieve its optimum performance. A new battery, or battery that has not been used for several months, may cause a premature fully charged indication as well. Ignore this indication and let the battery charge for several hours. Don't worry, it's perfectly normal.


How do I know when my battery fails?

When you have used a battery for more than 1.5 years, if the rechargeable battery begins to die, you will notice a significant decline in the running time of the battery.


How long do batteries last?

The general rule of thumb is between 600 to 1000 charge/discharge cycles for a NiCad or NiMH battery and 300 to 600 charger/discharge cycles for a Li-Ion one. This translates into battery life about 3 to 5 years of Nicad or NiMH and 1.5 to 3 years of Li-Ion for the average user at normal usage condition.

 How to use a battery correctly?

• When recharging a new battery or one that has not been used for months, your charger or device may indicate the battery has been fully charged after a few minutes. Please do not disconnect the battery and charger, because the recharging is not completed yet. The charger will recharge the battery in about 10 hours. This is not a problem. The same battery will be fully recharged within 2-3 hours next time. The battery will require 3 to 5 charge/discharge cycles before achieving its rated capacity. 
• When battery not in use, remove it from your device and store it in cool dry place. 
• Do not short-circuit terminals. Most of our batteries are protected with an internal self-resetting fuse, but short-circuit may still cause severe damage to the battery. Be careful where you set the battery down. 
• Keep away from fire and other sources of extreme heat and do not incinerate when disposing of the batter, otherwise it may explode. 
• Under no circumstances should you attempt to dismantle battery. 
• Do not expose battery to rain or moisture. 
• Do not drop, hit or otherwise abuse the battery as this may result in the exposure of the cell contents, which are corrosive. 
• Do not use battery at temperatures below -10C (15F) or above +40C (105F). Use of battery at very high temperatures will activate the safety circuit disallowing use.

How to prolong rechargeable Li-Ion battery?

• Avoid frequent full discharges because this puts additional strain on the battery. Several partial discharges with frequent recharges are better for Li-Ion than one deep one. Recharging a partially charged Li-Ion does not cause harm because there is no memory. (In this respect, lithium-ion differs from nickel-based batteries.) Short battery life in a laptop is mainly cause by heat rather than charge/discharge patterns. 
• Keep the lithium-ion battery cool. Avoid a hot car. For prolonged storage, keep the battery at a 40% charge level. 
• Consider removing the battery from a laptop when running on fixed power. (Some laptop manufacturers are concerned about dust and moisture accumulating inside the battery casing.) 
• Observe manufacturing date. Do not buy old stock, even if sold at clearance prices. 
• If you have a spare lithium-ion battery, use one to the fullest and keep the other cool by placing it in the refrigerator. Do not freeze the battery. For best results, store the battery at 40% state-of-charge.
