Dimensions

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.

The battery isolator l purchased from you guys is serving me well with no issues.l don't have to worry about my starter battery running down except for unrelated reasons.

The 95 amp isolator is an excellent unit. Used on my RAM 2500 diesel pickup for my pop-top camper, this unit is quite sufficient to keep both my dual truck batteries and dual camper batteries charged by my 160 amp OEM alternator. Quality gear; Highly recommended! Mike Lt. Col. USMC (Retired)

Timely delivery arrival, very good packing job, undamaged NEW items arrived due to good customer service. This is definitely a high quality unit. The heat generating epoxy-sealed electronics are protected from overheat by a generous amount of blue-anodized extruded aluminum cooling fins. This is a good value, and it is the reason that I bought 2 of them... One for use, and another for a back-up, in case I have a shorted battery... Keep-up the good work!

Review from a similar DBI in Battery Charger


Ordered by phone with Gwen and Stacy's help and elected to pickup the battery isolator in Wentzville, Missouri. Price was great and it has a one-year warranty. Within an hour or two they emailed it was ready. Pickup was also quick and professional. Item is an exact replacement for the 25-year-old failed part in terms of form, fit and function. Installed without rewiring or drilling and is working great! This could not have been a better experience!

  • 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 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...

  • Can the Deka Battery Isolator DW08770 Be Used On a Boat
    Yes, the Deka Battery Isolator part # DW08770 can be used on a boat to separate the starter and auxiliary battery but you would need to mount it in a location that is least likely to get wet, like in a battery box, the NOCO Snap-Top Battery Box with Strap part # 329-HM318BKS.

  • 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.

  • 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.

  • Does E Circuit of Isolator DW08770 Need to Be Completed
    The E circuit needs to be completed on the # DW08770 in order for the circuits of the isolator to be completed. If that circuit does not run to a 12 volt source it would not allow the circuits to complete. Typically this is ran to a keyed power source so that the circuits are only active when the vehicle is running. So basically you have to run it to a power source to turn it on. You can do this by running it to a power source that is on all the time if you have no need for it to turn off...

  • 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.

    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...

    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.

  • 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.

  • Battery Isolator for 1991 Jamee Motorhome to Prevent Battery Drain
    In motorhomes with multiple batteries there should be an isolator already in place that prevents the main battery (that starts the engine) from being depleted by the auxiliary battery that powers the interior lights. An example of such an item is the Tow Ready part # TR118665 which acts like a switch that opens and closes. This is rated for 80-amps. We also offer higher-rated isolators # DW08770 (95-amps) and # DW08771 (120-amps). Battery power will pass between the left and right terminals...

  • How to Select Battery Isolation Solenoid for 1985 Class C RV
    The solenoid in a battery isolator like Tow Ready # TR118665 can last a very long time but since they typically do not provide any sort of warning before failure replacing a 22-year-old one does seems like a reasonable bit of preventive maintenance. What you might consider is the current load the isolator can handle versus the actual demand from the trailer battery. Isolators come in various current capacities to match the demand on them. You might check your trailer battery amperage...

  • 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...
