LR03 alkaline battery.A 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 frequently require a large amount of lithium batteries will choose to stock a portion of the batteries after purchasing them. Some batteries can be stored for several months, while others can even be stored for a year or longer. When the battery needs to be used, it is found that the battery cannot be turned on and used after being taken out of the warehouse. The test does not output voltage. At this time, the user may judge that the battery is broken, or think that the battery quality is not good, etc. In fact, such judgment may be incorrect because the battery protection circuit itself has a sleep function. After a long time of not using the battery (without charging or discharging process) and reaching the set time, The working state of the protection circuit will enter low-power sleep mode. At this time, the main control IC of the protection circuit will disconnect the drive to the charging and discharging MOS, thereby achieving the goal of reducing the battery's own power consumption. To restore the battery output, simply 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 * (between 3.65-3.95V)

　　3: Every three months, batteries should be inspected and low-voltage batteries should be recharged.
