CR1625 battery.Solution to the lack of voltage caused by long-term storage of lithium batteries

　　Long term storage of batteries can result in a situation where there is no power to output, which is usually caused by the battery protection circuit entering a sleep state. Charging can activate the protection circuit. Lithium battery processing manufacturers provide answers for everyone.

　　Most users who often require a large amount of lithium batteries will choose to stock some of them after purchasing them. Some batteries can be stored for several months, while others can even be stored for a year or more. When the battery needs to be used, it is found that it cannot be turned on and used after being taken out of the warehouse. The test results show that there is no output voltage. At this time, the user may determine that the battery is broken or that the battery quality is poor, etc. In fact, this judgment may be incorrect because the battery protection circuit itself has a sleep function. After a long period of time without using the battery (without charging or discharging process), the set time is reached, The working state of the protection circuit will enter a low-power sleep mode. At this time, the main control IC of the protection circuit will disconnect the driver of the charging and discharging MOS, thereby achieving the goal of reducing the battery's own power consumption. To restore the output of the battery, it is only necessary to charge the battery and activate it immediately. In view of this, as a professional lithium battery customization manufacturer, we recommend that customers:

　　1: The stored batteries (exceeding 3 months) must be placed in a dry and temperature range of -10 ℃ to 45 ℃;

　　2: The recommended storage battery voltage is N * (3.65-3.95V)

　　3: Check the battery every 3 months and replenish the low voltage battery.
