Frequently Asked Questions (FAQ) About Battery

    Q: How to classify the battery?
    • Batteries are grouped into following categories:
    • Alkaline battery
    • Zincic carbolic battery
    • Lead-Acid battery
    • Nickel-metal-hydride
    • Nickel-cadmium
    • Lithium battery
    • Li-ion battery
    • Li-polymer battery
    • Fuel cells
    • Solar cells
    • Other types of battery
    Q: How do you take care of a battery?
  • It depends on the system. A Ni-Cd battery, for example, must always be thoroughly discharged before being charged. The best way to do this is to use a charger with a discharge function. Occasional "cycling" is good for all batteries: The batteries are discharged and recharged several times in a row. This restores the performance that was limited by the memory effect.
  • Q: Can batteries really be used 1000 times?
  • Yes. However, mostly only under laboratory conditions that often cannot be achieved in reality.
  • Q: Can cells get hot while charging?
  • No. They are allowed to warm up, but not really hot. If you do, they are either overloaded or defective. A good charger recognizes the sudden increase in temperature and switches off. A good cell phone battery has a thermoswitch that switches off the charging function at approx. 70 ° C and thus prevents overcharging and overheating.
  • Q: Will fast charging damage my battery?
  • No. Charging in quick chargers takes about 1-2 hours, in contrast to over 10 hours charging time with normal chargers. The relatively high current of the quick charger, however, requires a particularly reliable shutdown as soon as the full charge is reached.
  • Q: What causes short lifetime of battery? How to prolong the lifetime of battery?
    • 1)Reason:
    • a.Charger or electro circuit can't be fit for the battery.
    • b.Overcharge and overdischarge, etc.
    • c.Battery can't comply with the charging requirement
    • 2)Solution:
    • a.Charge the battery after it automatically powers off , then full charge the battery.
    • b.Avoid erroneous usage of battery, such as heavy pressure, short circuit, fall off and so on.
    Q: How long do rechargeable battery last?
  • Most laptop battery can be normal used in 400-500 charge and discharge cycles, in another word, a laptop battery should be normal in 2 year.
  • Suggestion: you should 100% discharge the battery power and overcharge it for 4-5 hours, to eliminate the memery effect, if it can not recover, you'd better to get a new one.
  • Q: How can i store my Lithium Ion battery?
  • It is best to store a lithium-ion battery with a partial or full charge. Occasionally, a lithium-ion battery with a very low charge is stored for a long period of time (many months) and its voltage slowly drops to below the level at which its built in safety mechanism allows it to be charged again. If the battery is going to be stored for several months it's a good idea to take it out and recharge it after a few months. Better yet would be to actually use the battery every few months and then leave it partially or fully charged.
  • In addition: Make sure charger and discharge completely at the first three times.
