Detailed Description

The BP12 requires a regulated charging source (provided by the CH150 or CH200 regulator connected to an unregulated solar panel or a wall charger). The BP12 includes a 24 in. attached cable that terminates in a connector for attaching the battery to a CH150 or CH200 regulator. The BP12 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 BP12 is shipped with hardware for mounting the battery in our enclosures. An ENC16/18 or larger enclosure is recommended.

  1. Yes. These leads are pn 22024, Battery Cable.

  2. Yes. It is a good idea to fully charge the BP12 with the CH100/CH200 before deployment.

  3. 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.

  4. Yes. The BP12 Mounting Bracket is available as pn 8061. To mount the bracket to the enclosure’s backplate, it may be necessary to purchase four pn 505 screws and four pn 6044 grommets.

  5. 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.

  6. Trickle chargers and float chargers vary. It is possible to do this, but ensure that the regulator voltage will match the battery specifications [13.65 V – (18 mV) x (T-25°C)] for float charging.
