    2081 Dual Battery specs:
    • Weight is 24 lbs
    • Dimensions: 8.25" W x 3.5" D x 9.25" H
     
    2082 Quad Battery specs:

    These batteries are for those who demand the most of a portable battery and want it to have high end features. The 2081 has 2 cigarette lighter jacks and the 2082 has 4, each one individually fused with a quality circuit breaker. There is an LCD display to indicate remaining voltage. Pressing the red button next to the display will give the state of charge of the battery.

    The power jacks have permanently attached plastic caps that will flip closed to keep dirt out of the jacks when not in use.

    The cordura carry bags have a couple of bult in pockets to accomodate various batttery accessories, such as cables or the charger.

    These Power Packs have the muscle to meet the demands of the modern amateur astronomer / imager. They are rugged, beautifully made and dependable. With proper care they will last for 5 years or 500 charges, whichever comes first. A battery float charger is included with these batteries.

    The included charger will never overcharge your battery and may be left plugged into the battery for extended periods of time without harming the battery. We offer an optional 6 amp float charger that will charge the #2082 battery in 5 to 6 hours (not recomended for the #2081). Customers outside of North America will need to choose a battery charger with a plug that is appropriate for their country (see the shopping cart below).

    When your battery dies, do not throw it away! The battery inside these units are easily replaceable! See our battery replacement instructions here.

    and battery charger.

    We have re-introduced these Power Packs due to popular demand.

    Many GoTo mounts run best when provided with 18 volts of power. These Power Packs have a built in inverter that will invert the electricity of one output to 18 volts.

    The 18 volt output has a special plug to prevent accidentally plugging in an accessory that should only be used at 12 volts. To use the 18 volt output of these units, you will require one of our special cables. These cables can be seen a little further down this page. We have stock 18 volt cables for Meade LX200 Classic telescopes and Losmandy Gemini GM8/G11 EQ mounts. If you have a mount that requires, or works best at 18 volts and you do not see a cable for it here, please contact us. We can make cables for most of the scopes and EQ mounts on the market.

    These Power Packs are built using the same quality components we use in our #2081 and #2082 Power Packs.

    NOTE: Coiled Power Cords are not provided with these batteries. They must be purchased seperately.

     12 VOLT to 18 VOLT INVERTER  

    This is a stand-alone inverter that will convert 12 vdc to 18 vdc. This is an excellent product for anyone who already owns a battery and needs to provide 18 volt power to a GoTo telescope or mount that runs best on 18 volts.

    Simply plug the inverter into a cigarette lighter socket on your battery and the inverter will change the 12 volts on your battery to 18 volts.

    This is the same inverter that is built into our 2081-18 and 2083 batteries but is now built into its own box.

    This device will require the purchase of one of our specialized coiled cables to power your telescope mount. The coiled cable goes from the inverter to your telescope mount's power plug.

     CHARGING YOUR BATTERY  

    IMPORTANT NOTE: Do not discharge your Kendrick battery below 11.6 volts as it may be damaged internally. When charging the battery, be sure to plug the charger into the battery first, then into a wall socket. Failure to do this will result in the battery failing to charge.

    The charger will never overcharge the battery and may be left plugged into the battery for extended periods of time without harming the battery. We have a 6 amp float charger available that will charge the 2082 or 2084-33 battery in 5 to 6 hours (not recomended for the 2081 or 2084-12). Customers outside of North America will need to choose a battery charger with a plug that is appropriate for their country (see the shopping cart below).

    NEVER use an automotive charger to charge these batteries. It will ruin the battery. Automotive chargers charge at a higher voltage than other battery chargers. If the charger charges at 14.8 volts or higher, the electrolyte will begin to turn to gas and ruin the battery. In a normal car battery this is not a problem as the battery can be topped up. In a sealed battery (which ours is) the electrolyte that turns to gas will be vented through its seals and cannot be replaced."

     WARRANTY  

    Customers are strongly encouraged to inspect and test their battery immediately upon receipt. Check to make sure it is fully charged, that the LCD display works correctly, that the charger works properly.Also, be sure to continue to check the voltage for several days after receiving it. It should hold its voltage. If it does not, contact Kendrick.

    The battery is under warranty for three months from date of shipping. The rest of the battery pack is under warranty for 6 months after the date of purchase. Consequential damages for malfunctions, resulting from accident, misuse, abuse, failure to follow operating instruction, or unauthorized repairs will void this warranty.

    Every battery is shipped in a heavy duty shipping box. Customers are requested to keep this box for the warranty period in case the battery should ever need to be returned for maintenance or warranty replacement. BATTERIES MUST BE RETURNED IN THEIR ORIGINAL SHIPPING BOX FOR WARRANTY REPAIRS/REPLACEMENT. Warranties for batteries will only be honored on batteries shipped in their original packaging.

     SHIPPING OF BATTERIES  

    SHIPPING NOTE FOR BATTERIES:
    Batteries will only be shipped by FedEx ground. If you need a faster level of service please specify in the comments box on the order form or call us at 1-(800) 393-5456.
