cool place away from heat and metal objects. The C42N1728 batteries will self-discharge during storage; remember stored at about 
40% state-of-charge.&lt;/li&gt;&lt;li&gt;Charge and discharge - For lithium ion 
batteries, you do not need to discharge them fully and recharge 
constantly. You need to do a full discharge only about every 30 charges.
 Do not charged to higher voltages than its threshold voltage&lt;/li&gt;&lt;li&gt;Exercise
 Your C42N1728 Battery - Do not leave your batteries dormant for long 
periods of time. We recommend using the battery at least once every two 
to three weeks. If a battery has not been used for a long period of

 propping your laptop on a pillow, blanket, or other soft surface that 
can heat up. Your C42N1728 battery is a lot less efficient when not 
within its standard operating temperature range.&lt;/li&gt;&lt;/ol&gt;&lt;p&gt;&lt;b&gt;Attention:&lt;/b&gt;&lt;/p&gt;&lt;ul&gt;&lt;li&gt;If
 the capacity is low in current,CPU will be in electricity-saving model 
and battery can not be charged.In this case,take off the battery and fit
 on to rouse the CPU. The  C42N1728 battery can be charged then.&lt;/li&gt;&lt;li&gt;Remove the battery when don't use if for long time,or the currency will be lost and the cell will be damaged.&lt;/li&gt;&lt;li&gt;Recharge
 the battery as the circle more than once per month to make the 
management of capacity reach its best status, and prolong C42N1728 Battery useful life.&lt;/li&gt;&lt;/ul&gt;
