battery for d620  
Battery will be used after a period of time "aging" of the. Specific manifestations of resistance become larger, the voltage across the charging time increased quite rapidly, so it is easy to charge control battery for d620   circuit is judged to have full capacity will naturally be "down". As the larger battery internal resistance, discharge voltage drop, high speed, the system can easily mistaken for a voltage not enough, power is low (in fact there is not power up). As can be seen from the above description of the battery is a vicious cycle of aging process, the discovery of battery time out faster than what it should be tempered, or else will be finished sooner or later. battery for d620
