6 CAUTIONS IN USE（谨慎使用）
To ensure proper use of the battery please read the manual carefully before using it.
（为确保正确使用电池，使用前请仔细阅读本细则）
Handling（电池操作）
l Do not expose to, dispose of the battery in fire.（不要靠近和放置电池于火中）
l Do not put the battery in a charger or equipment with wrong terminals connected.
（在充电器或设备仪器中不要把电池接错电极）
l Avoid shorting the battery（避免电池短路）
l Avoid excessive physical shock or vibration.（避免电池过多的物理撞击和震动）
l Do not disassemble or deb the battery.（不要解剖和使电池变形）
l Do not immerse in water.（不要把电池浸泡在水中）
l Do not use the battery mixed with other different make, type, or model batteries.
（不要和其它不同类型的电池混和使用）
l Keep out of the reach of children.（放置电池于儿童不易接触的地方）
charge and discharge（充电和放电）
l Battery must be charged in appropriate charger only.（电池必须用适当的充电器充电）
l Never use a modified or damaged charger.（不要使用改装或损坏的充电器）
l Do not leave battery in charger over 24 hours.（不要把电池放置于充电器超过24h）
storage（储存）
l Store the battery in a cool, dry and well-ventilated area.
（应把电池置于凉爽、干燥及通风良好的区域）
disposal（电池处理）
l Regulations vary for different countries. Dispose of in accordance with local regulations.
（电池处理要符合当地的规定）
7 Period of Warranty/保质期
The period of warranty is one year from the date of shipment. Great Power guarantees to give a replacement in case of cells with defects proven due to manufacturing process instead of the customer abuse and misuse.
电池的保质期从出货之日算起为一年。如果电池的缺陷是在制造过程中形成的而不是由于用户滥用及错误使用造成，本公司负责退换电池。
8 Storage of the Batteries/电池的存放
The batteries should be stored at room temperature, charged to about 60% to 80% of capacity.
We recommend that batteries be charged about once 3 months to prevent over discharge.
电池应当在室温下存放，应充到60%至80%的电量。如长时间储存，建议每3个月充一次电以防止电池过放电。
9 Other The Chemical Reb/其它化学反应
Because batteries utilize a chemical reb, battery perbance will deteriorate over time even if stored for a long period of time without being used. In addition, if the various usage conditions such as charge, discharge, ambient temperature, etc. are not maintained within the specified ranges the life expectancy of the battery may be shortened or the device in which the battery is used may be damaged by electrolyte leakage. If the batteries cannot maintain a charge for long periods of time, even when they are charged correctly, this may indicate it is time to change the battery.
由于电池是利用化学反应的原理，所以随时间的增加电池的性能会降低，即使是存放很长一段时间而不使用。如果使用条件如充电、放电及周围环境温度等情形不在指定的使用范围内，会使缩短电池的使用寿命，或者会产生漏液导致设备损坏。如果电池长周期不能充电，即使充电方法正确，这样需要更换电池了。
10 Note/注释
Any other items which are not covered in this specification shall be agreed by both parties.
本说明书未包括事项应由双方协议确定。
*声明：本规格书信息仅仅是对产品性能的简述，并不意味着是对任意一只电池做出的担保。电池的相关参数可以在未通知的情况下自主进行修改，请及时与宝力晟保持联系以取得最新资料信息。
