What are NiCd, NiMH and Li-Ion Batteries?
The Nickel-Cadmium battery (commonly abbreviated NiCd and pronounced "nye-cad") is a popular type of rechargeable battery using the nickel hydroxide (NiOH) and metallic cadmium (Cd) as the active chemicals.
The advantages of NiCd over other rechargeable types is lower weight for a given quantity of stored energy, good charging efficiency, small variation in terminal voltage during discharge, low internal resistance, and non-critical charging conditions. They are still chemically the same as regular batteries. However, this kind of chemistry suffers from "memory effect", this means that NiCd battery should be fully discharged before every charging cycle. Otherwise, it will shorten the life of the battery.
The Nickel-Metal Hydride battery, (commonly abbreviated NiMH) is a type of rechargeable battery similar to a Nickel-Cadmium (NiCd) battery but has a hydrogen-absorbing alloy for the anode instead of cadmium. Like in NiCd batteries, nickel is the cathode. A NiMH battery can have two to three times the capacity of an equivalent size NiCd and the memory effect is not as significant as NiCd. However, compared to the lithium-ion (battery, the volumetric energy density is lower and self-discharge is higher. They are still chemically the same as regular batteries
Lithium-ion batteries (sometimes abbreviated Li-ion batteries) are a type of rechargeable battery commonly used in consumer electronics. They are currently one of the most popular types of battery for portable electronics, (such as digital cameras, camcorders and media players) with one of the best energy-to-weight ratios, no memory effect, and a slow loss of charge when not in use.
How to use a battery correctly?
When charging a new battery or recharge the one that has not been used for a long time (over 6 months), your charger may indicate that the battery has been fully charged in just few minutes. In this case, please do not unplug the charger or remove the battery from the charger. Actually, the recharging process is still in progress, let the battery being charged for 8 - 9 hours before disconnected the charger from the AC power outlet. Don't worry, this is normal for a new and long unused rechargeable battery. The battery will back to normal capacity after 2 to 5 recharging cycles, and the charging time will also minimize to 2 - 3 hours.
As always, it's dangerous to charge a battery unattend.
How to take care of battery?
When battery is not in use for a long time (over 3 months), remove it from your device and store it in a cool dry place immediately.
Do not mix use of old and new batteries together
Do not short-circuit terminals. it may cause severe damage to the battery.
Battery should be covered or stored in an individual protecting case.
Keep away from fire and other sources of extreme heat.
Do not attempt to dismantle battery
Do not throw the batter into fire when disposing of the battery, or it may explode.
Do not store the battery outdoor, because the extreme hot and cold environment will shorten the life of the battery
Do not expose battery to water, rain or moisture.
Do not drop or hit the battery, it will cause the leakage of corrosive material
How to maximize performance?
Mark sure the battery is fully recharged before use.
Do not mix use of old and new batteries together
Often clean the battery and terminals with a dry cloth.
With NiCd and NiMH batteries, it's best to do the charging recycle monthly.
Li-Ion batteries do not need to complete the charging process monthly, because Li-lon batteries has no memory effect
Remove the battery from charger or electronic devices when not in use for over 6 months
How to prolong rechargeable Li-Ion battery?
Recharging a partially charged Li-Ion battery does not harm because there is no memory effect, but that's not good for NiCd and NiMH batteries
Keep batteries cool all the time when not in use.
Do not mix use of old and new batteries together
Keep the battery at 60% charge level when it's going to be stored over 6 months
How is a battery evaluated?
mAh: the commonly seen milliampere-hour (mAh) is equal to 3.6 coulombs
The higher the mAh rating, the longer and more power a battery will hold its charge between each charging cycle.
The commonly How to dispose a battery?
Once a battery loses power, remove it immediately from its device or it may cause leakage.
Do nott store it in your pocket or purse as this may cause it to burst.
Don't bang the battery in any situation; it can emit a charge that may cause them to ignite.
There're thousands of recycle outlets in your neighbourhood retail stores.
Do I need extra or backup batteries?
Batteries are the most important accessory for portable electronic device. Unlike traditional cameras, which can be used for months or years without changing a battery. They consume less electricity than the digital cameras. It's ideal for every digital owner to have 1 or 2 rechargeable batteries for the back-up use purpose. Once your digital camera is running of battery power, you can't grab one from your nearby gas station or convenience store, because most of the batteries designed for digital camera are proprietary. It's not available at your convenience. Even you get it, you need to complete a charging process before it works perfectly. Imagine you are traveling overseas or somewhere else, and you need to take some pictures or video clips in order to keep your best memory forever. You just find that your camera / camcorder is running out of battery! So it¡¯s wise to have at least one backup battery whenever you want it because you'd never know when you need it.
According to our customer's feedback, over 99% of digital camera owners own at least one battery for their back-up purpose.
Why my new battery won't hold a charge?
Your battery might be loose. Please check the connection between the battery and the device to make sure the battery is securely attached. If you still have troubles to charge the battery, either your battery or your charger/device is defective.
Why my new battery has a very short running time even "fully" charged?
When charging a new battery or recharge the one that has not been used for a long time (over 6 months), your charger may indicate that the battery has been fully charged in just few minutes. In this case, please do not unplug or remove the battery from the charger. Actually, the charging process is still in progress, let the battery being charged for 8 - 9 hours before disconnected the charger from the wall outlet. Don't worry; this is normal for a new and long unused rechargeable battery. The battery will back to normal capacity after 2 to 5 recharging cycles, and the charging time will also minimize back to 2 - 3 hours.
As always, it's dangerous to charge a battery unattend.
How do I know when my battery is not good?
When a battery has been used for more than 2 years, and with frequently charging process, the rechargeable battery begins to lose its charge gradually. Hence the running time of the battery is significantly declined.
How long do batteries last?
Li-Ion: 300 to 600 charge - 2.5 years
NiCad or NiMH: 600 to 800 charge cycle - 3.5 years
Why my battery isn't giving as much power as it used to do?
Probably your battery is suffered from "memory effect" (NiCd and NiMH batteries). In order to minimize this effect, discharge your battery completely on a regular basis before each charging cycle.
Why is my fully charged battery losing power when not in use for few weeks?
Fully charged batteries will gradually lose their charge, even when they are not used. If you have not used the battery for few weeks, we suggest that the battery should be recharged again before use (if it's NiCad or NiMH battery, a discharge process should be performed before a new charge cycle). Actually, all rechargeable batteries will lose their charge daily no matter they're stored or unused. It's an absolutely normal situation. Simply repeat the correct charging process, the lost power will be back into the batteries again.
How to find the exact battery that I need?
Check your device manual or simply take a look of the battery that you are currently using, you will find the chemistry type (NiCad, NiMH or Li-Ion) and part number of the battery there. For example, if you have Nikon D-70 SLR camera, the battery part number is "EN-EL3E" with Li-Ion chemistry. Besides, you can type any information that you have regarding your camera (such as brand name, manufacturer, camera model number) in the SEARCH BOX and then click "GO", our smart search engine will find out all the compatible batteries and other accessories for you in just a second.
