  1. How long does a 6182 or 17894 last after a full charge?

    This depends on the current drain of the system. In general, the battery can be made to last longer by following these steps:

    1. Just before measuring the high-current sensors, slow down the scan interval of the data logger program and switch on the sensors.
    2. Just after the sensors stabilize, take the measurements.
    3. Turn the sensors off immediately.

    Communication can also greatly affect the battery charge. Turn off any communications devices as much as possible to delay the battery discharge. 

    Adding a solar panel and working out a power budget can balance out the charge with the discharge so that the system can be stable indefinitely. For more information, see the “Power Supplies” application note.

  2. If a fully charged 6182 or 17894 battery is used without a wall charger or solar panel, how long will the battery continue to supply power to a data logger?

    This depends on the current drain of the system. For more information, see the “Power Supplies” application note.

  3. What type of battery are the 6182 and 17894 (for example, nickel, alkaline, etc.)?

    The 6182 and 17894 are valve-regulated lead-acid (VRLA) maintenance-free batteries, also known as sealed, lead-acid batteries.

  4. How can the age of a sealed rechargeable battery be determined?

    Look for a stamp on top of the battery. The stamp may be in a date format of YYMMDDXX where:

    • YY is the year.
    • MM is the month.
    • DD is the day.
    • XX is the manufacturing plant.

    This indicates the age of the battery.
