- 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.

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!

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!

While it was a challenge to put it in our motorhome, once installed, it works perfectly. It appeared almost identical to the original one I removed on our 1996 Road Trek.

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!

Great selection and very reasonable prices, many with discounts, often cheaper than that big online site. Particularly impressed with customer service when I had a product issue, called me right away and offered replacement item immediately with free UPS return label.

See what our Experts say about this Deka Battery Charger
- Deka Battery Isolator # DW08770 Recommendation for Charging Van Camper Second BatteryFor you application the Deka Battery Isolator # DW08770 would be a solid choice and a great solution. It will allow you to charge your auxiliary batteries from your alternator while preventing the aux batteries from draining the main battery when the vehicle is off. It also enhances the alternator charge to make it ideal for charging a battery.
view full answer... - Does E Circuit of Isolator DW08770 Need to Be CompletedThe 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...
view full answer... - Deka 4 Post Isolator InstallationThe 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.

- Battery Isolator For 1991 GMC K-250 The Deka Battery Isolator, part # DW08770 is designed Battery Isolator will allow two batteries in your 1991 GMC K-250 to charge at the same time and will protect the starting battery from being drained by the accessory battery, even under a heavier load. I have attached a drawing that shows how the isolator is installed Terminal 1 connects to the positive battery terminal of the main battery. The original wire from the alternator to the main battery would be removed from the battery...

- Can Deka Battery Isolator # DW08770 be Used with Lead Acid and Lithium BatteriesThe 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.

- How To Protect the 12 Volt Circuit On a 7-Way From a GeneratorIt 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.
view full answer... - How to Wire 95 Amp Deka Battery Isolator for Installation on 1986 Toyota 4RunnerYes, what you say is correct and how the 95 Amp Deka Battery Isolator # DW08770 should be wired. You can use the Installation Kit # DW08769 for some of your wiring and a 50A circuit breaker.

- Wiring Kit to Install Deka battery Isolator on a 2015 Toyota TacomaThere 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.
view full answer... - Amperage Ratings of Deka Battery Isolators DW08770 and DW08771A 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.
view full answer... - Parts Needed to Install Additional Battery in Truck for Truck Bed CamperYou 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.

- Wiring Diagram for Deka 95-amp Battery Isolator # DW08770The 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...

If your truck has a CS alternator you will use installation kit # DW08768. If it has the SI alternator use kit # DW08769. The difference will be in the part number of the alternator. An SI has SI as the last two digits of the number. The other way to tell is that the SI has...

- Battery Isolator for 1991 Jamee Motorhome to Prevent Battery DrainIn 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 part # PK5231201 which acts like a switch that opens and closes. This is rated for 100-amps. We also offer other isolators # DW08770 (95-amps) and # DW08771 (120-amps). Battery power will pass between the left and right terminals only when...
view full answer... - How to Provide Trigger Signal for Deka 95-amp Battery Isolator DW08770A 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.
view full answer... - Troubleshooting Battery Isolator InstallationThank 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...

- 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...
view full answer... - Can the Deka Battery Isolator DW08770 Be Used On a BoatYes, 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.
view full answer... - Adding Circuit Breaker/Fuse to Battery Isolator InstallationRegarding 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...
