1. Use the appropriate battery:

    2. During using the portable listening ,we should pay attention to the table note the battery type and size in the machine. Do not mix old batteries and new batteries together, and do not use different models or different brands of batteries,such as Dell latitude d820 battery and Sharp md-mt66 battery .

  2. Clean the battery slot of the positive and negative contact:

    3. As the dust and dirt will affect the electrical conductivity results, you need to occasionally clean the np-f330 battery slot of the positive and negative metal contacts. A rubber can make you achieved very good results (note other places not to be dirty by the rubber crumbs ).

  3. Timely replacing battery

    4. When prompted, “power shortage” mean you should timely replace the battery. (Generally for using the non-rechargeable type of latitude d600 battery) Do not heat the battery to extend its service life or to any non-rechargeable battery charge time.

  4. Batteries are exposed to cold:

    5. In extremely cold weather, try to avoid sb-lsm80 battery appear in the outside of the room, pay attention to the temperature of outside the battery.

  5. Low-temperature storage:

    6. The battery can be stored in the low-temperature environment,it reduce the battery’s self-discharge rate, but pay attention before being used to avoid the dew. Do not store batteries in high-temperature environments, especially in the humidity, and a great temperature difference, and promising not to replace the np-fh70 battery , on the one hand ,we consider Walkman of the circuit, on the other hand, taking into account the battery life of its own, and internal storage dielectric have a direct impact on battery life.
