1 .whether the battery used or don,t use for a long time can be stored in the electric appliances?

If the  electrical  appliances not to be used for a longer period of time , it is best to remove the battery and put itin a cool, dry place, if not, even if the  electrical appliances are switched off, the system still will have a low batterycurrent output, which will shorten battery life.

2 . What the  possible reasons of battery  appears zero voltage or low  voltage?

⑴ Battery suffer from external short circuit or overcharge, anti-charge(Mandatory over discharge ) ;

⑵ batteries by the high rate of large current continuous overcharge, lead to battery pole core inflation, the positive directly contact with the short circuit;

⑶ battery internal short circuit , or slightly short , such as: positive and negative film penetrate the separator paper burr contact shorting , positive and negative film placed in contact improper short pole piece , or contact with the cathode sheet steel shorted anode material into the separator paper out , separator paper itself is defective , the positive electrode lug contacts shorted anode sheet .

3 . What the  possible reasons of battery  appears zero voltage or low  voltage?

⑴ whether the single battery appears zero voltage ;

⑵ plug  with short circuit,   did not connect the plug  well;

⑶  The lead and battery take off welding or Virtual welding

⑷ internal battery connection error , the connection between the plate and the battery drain welding, Weld ,  etc. ;

⑸ battery internal electronic components are connected incorrectly , damaged.

4 .what the  reasons of the battery pack,s lifespan is short ?

⑴ charger and battery charging circuit type  is mismatch ;

⑵ overcharge, over-discharge ;

⑶ the type of battery pack do not match  electrical requirements

5 . what the possible reasons of  batteries, battery packs will not charge?

⑴ battery zero voltage or zero voltage of the battery pack in the battery ;

⑵ battery pack connection error , internal electronic components , the protection circuit is abnormal ;

⑶ charging equipment failure , no output current ;

⑷ low charging deficience due to external factors ( such as very low or high temperatures )

6 . what is the reasons Of battery , battery pack may not be able to discharge?

⑴ batteries after storage, use, lead to Lifespan  of attenuation

⑵ under charge or not charge ;

⑶ The environment temperature is too low ;

⑷Discharge efficiency is low, such as when  the large current discharge the ordinary batteries in a sharp drop in voltage electricity can not be released due to Internal material can't keep up with reaction diffusion speed.

7 Why the battery placed for a period of time, the electricity is power down ?

It is normal that after the battery placed for a period of time, the electricity is power down,rechargeable battery daily energy wastage rate of 1-3 % , the rechargeable battery should Charge immediately and use immediately, Long-term storage should be "wake up" the battery.

8 whether the battery overheat is normal when charging the battery ?

During charging, mild fever is a normal phenomenon , when the battery is severe fever , you should immediately stop , otherwise it will damage the battery.
