BP24 24 Ah 12 V Sealed Rechargeable Battery with Mounts

Overview

The BP24 is a rechargeable 12 Vdc, 24 Ah battery pack that can power a Campbell Scientific system. It is intended for high-current-drain systems, such as satellite transmitters, that require more power.

Technical Description

The BP24 requires a regulated charging source (provided by the CH150 or CH200 regulator connected to an unregulated solar panel or a wall charger). The BP24 includes a 24 in. attached cable that terminates in a connector for attaching the battery to a CH150 or CH200 regulator. The BP24 also comes with a 24 in. cable for use with the CR6 datalogger or other products that need a pigtail termination instead of a white connector. (This cable is bagged and taped to the battery.) Switching the standard cable for the pigtail cable is easily accomplished by the user. The BP24 is shipped with a bracket that secures the BP24 to an enclosure backplate. An ENC16/18 enclosure is recommended.

  1. 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.

  2. Does a BP24 need to be stored in some kind of enclosure, or does it simply need to be connected to the rest of the system?

    Campbell Scientific recommends keeping the BP24 in an enclosure to protect the terminal from rain and condensation that could short out the battery.

  3. Do dataloggers need their own batteries, or can they be powered directly through a BP24?

    Dataloggers require stable power supplies to work properly, such as the BP24. If the system is needed for a long-term application, recharge the battery frequently, or recharge it daily with a solar panel of the appropriate size.

  4. Is there a battery test kit to test BP24 battery packs out in the field to make sure they are good?

    We do not offer a battery test kit. However, the CH200 charge regulator does have some features that could aid in discovering a bad battery, such as the ability to measure amperage into and out of the battery. Campbell Scientific recommends taking a voltmeter into the field to verify the battery voltage at different points to see if a dirty or corroded connection is causing a voltage drop in the system.

  5. Is a BP24 with a CH100 equivalent to a PS24?

    Not quite. The PS24 consists of a 24 Ah battery, a CH100 regulator, and a 10 by 12 in. environmental enclosure. Aside from the enclosure, the PS24 is very similar to a BP24 combined with a CH100.

  6. Do airlines accept the BP24 on passenger planes as accompanied luggage?

    Check with the airline. Mention that the BP24 is a sealed, valve-regulated VRLA AGM battery.

  7. Is the CH100 compatible for use with two BP24 battery packs in series to provide 24 Vdc?

    No. The CH100 is designed to charge a 12 Vdc battery pack, not a 24 Vdc battery pack.

  8. Does a BP24 need a CH100 to work with an unregulated solar panel, or can the BP24 be connected directly to a regulated solar panel?

    The BP24 should never be connected directly to an unregulated solar panel. A voltage regulator, such as the CH100, must be included in the circuit, or damage to the battery will occur.

  9. Why is the battery in the BP12 and BP24 assembly taller than the bracket?

    The discrepancy is not a mistake—the bracket is intentionally designed to be shorter than the battery. When mounted inside an enclosure, the back of the battery rests against the mounting grommets. The lid to the mounting bracket compresses the battery slightly, holding the battery firmly in place.

  10. What is the difference between a PS24 and a BP24? Is a BP24 with a CH100 equivalent to a PS24?

    The BP24 consists of a 24 Ah battery and a cable, along with a mounting bracket that can attach the battery to the diamond-punched backplates in Campbell Scientific enclosures. 

    The BP24 with a CH100 and a 10 in. by 12 in. enclosure with special mounting brackets is equivalent to a PS24.

    The PS24 includes the BP24, a 10 in. by 12 in. enclosure, voltage regulator (CH100), back panel, mounting bracket and strap, and a longer power cable—all in one. The PS24 may be a suitable option when installing the battery in a separate enclosure because the datalogger’s enclosure is not large enough to house the battery. The PS24 is often used with the ET107 when a larger battery is required.
