Features:

  • Ideal for automotive, marine, and RV applications
  • Enhances your alternator performance for
    • Efficient charging
    • Maximum power
    • Longer battery life
    • Safer operation
  • Protects main starting battery from auxiliary drain
  • Regulates current for multi-battery system


Specs:

  • Application: alternators with amperage ratings below 95 amps
  • Capacity: 95 amps
  • Overall dimensions: 4" long x 4-1/2" wide x 2-1/2" tall excluding bolts
  • Quantity: 1
  • 1-Year limited warranty


Note: It is recommended that you purchase an isolator with an amperage rating above that of your alternator to prevent any damage to the isolator.


In a multi-battery system, the battery with the lower state of charge will drain power from the battery with the higher state of charge. This battery isolator protects your starting battery power so that no matter how weak your accessory battery becomes, the accessory battery will never drain power from the starting battery. This battery isolator also saves time by allowing simultaneous charging of both batteries. The amount of current flowing into each battery is determined by its state of charge, which guarantees that each battery will get fully charged, prolonging its life.

  • Wiring a Trailer With Dual Batteries and Solar Charger
    Let's try and take this one at a time to make things easier; to start with the black wire from the 7-way plug (the 12V) should be run to the pair of 12V batteries you already have in the battery box. In terms of grounding they will be grounded through your Redarc In-Vehicle BCDC Battery Charger # 331-BCDC1225D. The LED lights each need to be grounded to the frame of your trailer; they will also be connected to the 12V batteries which would be connected to the charger. That covers the...

  • How to Prevent Power Drain from Hydrastar Brake Actuator When Truck Is Turned Off
    Hi Ryan; if you want to prevent battery drain you could use a battery isolator # DW08770. The other option is to just unplug the trailer if you're going to leave it hooked up for a long period of time. I'm not entirely sure what that ping is so I would pay closer attention to it. It sounds like it is actually running and pulling power when it shouldn't be. If you have a Tekonsha controller that is EOH compatible you don't need the # HBA-CAM just make sure it is switched to EOH. Using the...

  • Charging A Trailer Battery From The 7-Way 12v Power Pin And Preventing Feedback
    The battery type doesn't matter in this situation as you could still face this issue with two AGM batteries. If you're vehicle is running the alternator should be charging the start battery more than the draw from the 7-way 12v accessory pin. As long as the alternator is properly functioning you shouldn't have an issue charging both batteries while driving. If the vehicle is off and the 7-way isn't tied to the ignition for power then you run the risk of draining the start battery if you're...

  • Deka 4 Post Isolator Installation
    The Deka Battery Isolator - 95 Amp # DW08770 does require the ignition switch be connected to the E post. This is how you ensure the batteries are isolated and the auxiliary battery does not draw power from the starting battery. You will want to use a 6 amp circuit breaker on the wire connected to the ignition switch run position as shown in the attached diagram. If you want to temporarily bypass the ignition switch you just need 12v on the E post.

    The Deka Battery Isolator # DW08770 is not vehicle-specific; it will work fine on your 2007 Chevrolet Silverado to protect the truck battery from excessive discharge and to regulate current in a multi-battery system. If your Silverado has a CS alternator you will use installation kit # DW08768. If it has the standard alternator use kit # DW08769. You can tell if you have the CS130 alternator by checking for its external fan with serpentine belt pulley. I have linked a wiring diagram for...

  • Parts Needed to Install Additional Battery in Truck for Truck Bed Camper
    You will need a battery isolator like the Deka # DW08770. This will install by running between your alternator and your truck's current battery. Then the second battery will run off the isolator as well. If you need a 120 amp isolator use # DW08771. For an install kit we have # DW08769.

  • Troubleshooting Battery Isolator Installation
    Thank you for all of the details and photos! It looks like you have the Deka Battery Isolator # DW08771 installed and you should have only 1 wire going to each terminal. I believe you're correct that the previous owner just winged it so we need to get that fixed. If we test the isolator and it's bad then I recommend replacing it with the one mentioned above and wiring everything as it should be. To test the isolator what you need is a multimeter like part # PT89ZR. Set the multimeter to...

  • How To Protect the 12 Volt Circuit On a 7-Way From a Generator
    It sounds like you are asking if you can use a battery isolator to protect the battery on your tow vehicle from the generator while powering items on your trailer. If that is the case then yes, the Deka Battery Isolator part # DW08771 will work for you. However, I doubt you will be drawing anywhere close to 120 amps so you would most likely save some money with the 95 amp version, part # DW08770.

  • Troubleshooting RV Alternator and Converter Not Charging Battery Bank
    I would be happy to help! The charge current coming from the alternator is not going through the converter portion of your your panel as a converter converts AC power from shore power or a generator to DC power for your batteries. Since the alternator on your RV is already setup for DC it does not go through the converter. First things first you will need to use a multimeter like the # PT89ZR to test the charge wire running from the alternator of your RV to your battery bank to see if...

  • BC to DC Charger to Allow Truck Alternator to Charge Lithium Batteries of RV
    Hey Chris, so lithium batteries do require charging at higher voltages so what you would need is a BC to DC charger like part # RED96FR which will take the output from your truck alternator and convert it to a charge that your lithium battery can be charged with. This also functions as an isolator as well so you'd have that covered too. The DEKA you mentioned is not what you are looking for so it wouldn't be what you'd need.

  • How to Provide Trigger Signal for Deka 95-amp Battery Isolator DW08770
    A battery isolator like the Deka # DW08770 and the higher-capacity 120-amp-rated # DW08771 need a 12V input signal to close them, which then allows battery power to pass through. You can turn that trigger signal on and off using a circuit controlled by the vehicle ignition key, such as a power antenna circuit, by using a fuse tap like # F2526. You certainly could use another method to switch that trigger signal on and off, such as a switched fuse.

  • Adding Circuit Breaker/Fuse to Battery Isolator Installation
    Regarding your 2003 Chevy Tahoe, the Deka # DW08770 Battery Isolator is not vehicle specific. I have attached the wiring directions. In the diagram where it calls for a "circuit breaker" you can also use an inline fuse. The best way to get a typical sized circuit breaker, heavy cable, and the connectors you will need to to purchase the Deka # DW08769 Installation Kit. If you do not have these already, you will need a basic voltage tester like the #PT89ZR and a good quality wire connector...

  • Wiring Kit to Install Deka battery Isolator on a 2015 Toyota Tacoma
    There isn't a special kit you would have to use to install battery isolator on your 2015 Toyota Tacoma unless it uses a Delco or GM CS alternator (which isn't likely). So you would use the regular kit, # DW08769.

  • Can Deka Battery Isolator # DW08770 be Used with Lead Acid and Lithium Batteries
    The DEKA isolator part # DW08770 is perfectly compatible with lead acid and lithium batteries. Those two types of batteries charge at different voltages but that wouldn't cause problems with the DEKA.

  • Amperage Ratings of Deka Battery Isolators DW08770 and DW08771
    A battery isolator should be rated for at least the same capacity as the alternator output and the higher-rated battery, but a higher-rated one would be great too as this would tend to potentially improve its durability in your application. We have several isolators, including the Deka # DW08770 rated for 95-amps and 120-amp-rated # DW08771.
