Expert Answers about Battery


  • How Do Batteries Charge with Deka Battery Isolator DW08771
  • If you intend to wire the two batteries together they should be the same type but if you want to add a second independent battery for the winch/lights/stereo it can be a different type and/or have a different amp-hour (Ah) rating. A separate system means no risk of depleting your vehicle's primary battery. You want to consider the power draw of each of the items and select a battery with a high enough Ah rating. The winch will draw much more power than the lights or stereo so that is...

You could attach this outlet directly to the truck battery or you could mount a separate battery on the trailer.

  • Powering Hydraulic Dump on Dump Trailer
  • If you are looking for something to power the dump on your dump trailer, I highly recommend an independent battery specifically for powering the dump trailer. We have a few different options for charging the battery on the dump trailer. Powering the dump off of the vehicle battery may put too much draw on the vehicle battery. One way you could charge the battery to power the dump trailer is using a NOCO Genius Battery Charger and Maintainer # 329-GENIUS5. This battery charger maintains...

  • CTEK Battery Charger for Re-Charging Two 12V Trailer Batteries
  • While you can wire two batteries' outputs in parallel when you're using them, when charging batteries it is always best to do each one individually. Shore-power chargers like the CTEK # CTEK56353 are the only way to fully re-charge a depleted battery. The +12V power circuit in your 7-way trailer wiring can deliver a worthwhile maintenance-level charge to the fully-charged batteries on your trailer to keep them topped off but that circuit simply doesn't have the current required to re-charge...

  • Can I Use My Alternator to Charge Lithium Batteries?
  • I am happy I have been able to help you. You would what to maintain a lead acid battery system separate from your lithium battery bank. To charge your lithium batteries correctly you will need to install a separate charger. You can't run them both directly off of the alternator without damaging your lithium batteries. I recommend the Redarc In-Vehicle BCDC Battery Charger item # RED96FR. The Redarc BCDC single-input battery charger allows for easy charging of your lithium battery. This...

  • Will Continuously Charging Breakaway Battery from Tow Vehicle Cause Any Damage
  • Using the Battery Charger # 20011, or any charger off of the tow vehicle's battery, will not cause any damage to your breakaway switch. The amount of charge will not charge the battery from dead to full but will maintain the charge. In addition, if you leave the trailer plugged into the tow vehicle's connector for a long period of time it will continue to draw power from the vehicle's battery. In this case it is possible to drain the vehicle battery. To avoid the draining you can install...

  • How to Charge the Batteries on a Trailer While Underway
  • You are correct that the power coming from your vehicles battery while traveling is only going to provide a maintenance charge to your batteries on your trailer. It will not charge a dead battery and it will not keep the trailers batteries charged if they are being used while underway. Using wiring and a solenoid like the # PK5231201 that you mentioned will provide a good maintenance charge while you're driving but that is about it. In order to charge and maintain a full charge you will...

  • Does the Precision Tool 2.5 Watt Solar Charger Work on 6v Batteries
  • I have a solution for you to keep the 6v battery charger on your tractor maintained, but the # PTW2997 is only designed for 12v batteries. However, you can use the Duracell Battery Charger and Maintainer # DU27FR to keep the battery charged and it would do a great job. This charger uses automatic multi-stage charging to extend battery life, so you'll never have to worry about over-charging. We do not currently offer a solar setup capable of charging a 6v battery.

  • Smart Battery Charger for 12V Car Batteries
  • For your Toyota RAV4 and charging 12V car batteries I recommend the NOCO Genius Smart Battery Charger - AC to DC - 6V/12V - 10 Amp item # 329-GENIUS10. The NOCO Genius charges and maintains lead acid and lithium-ion batteries. It has a start voltage sensor that detects dead batteries as low as 1 volt.

  • Largest Available Breakaway Battery for Trailer
  • I may have a solution for you, but the largest breakaway system battery we offer comes with a 10 amp hour battery # BRW87FR; the complete system is the Bright Way Push-to-Test Trailer Breakaway Kit with 2-Amp Charger and 10 Ah Battery - Top Load # 3802311. I'm not aware of a breakaway system that uses a battery that large and this would be the best solution we have available for this.

  • How to Charge Camper Battery Using 2006 Chevy Silverado 2500 Dual Battery Bank
  • The 7-Way 12V power only provides a trickle charge to the tow vehicle battery. This is due to the distance between the truck battery bank and the camper battery bank. In order to charge your camper battery bank you need a "booster/maintainer" that is able to get the charge to where it needs to be to properly charge your camper battery, and for this I like to recommend the Redarc BCDC: - 25 Amp Redarc In-Vehicle BCDC Battery Charger # 331-BCDC1225D - Trailer Installation Kit # e79ZR The...

  • Battery Charger for a Trailer Breakaway Kit Battery
  • Generally a breakaway kit is installed mounting the battery to the frame but it doesn't have to be. We carry a few different chargers separate from the kits themselves and I've linked our selection for you. The most popular of the chargers if the Hopkins # 20011. To install the Hopkins charger the black wire connects to the power coming from the vehicle battery, the red wire to the breakaway kit's battery, and the blue to the pin. I've also linked a video for you.

  • Parts Needed to Charge Auxiliary Battery in 2018 Subaru Outback with Vehicle Battery
  • Most battery chargers that you'd be looking at are all AC to DC power, so you can't use them off a car battery. A way around this would be to install something like the Redarc Redarc In-Vehicle BCDC Battery Charger - Dual Input - DC to DC- 12 Amp # RED96FR, which will allow you to trickle charge your auxiliary battery through your car battery. I really like the BCDC since it gives you the ability to integrate a solar panel like part # 34273836 so you've got 2 different sources to charge...

  • Recommended Chargers for 4 Battery and 2 Battery Banks on 2004 Discovery 39 Class A Diesel
  • To charge the 4 battery bank on your 2004 Discovery 39 I recommend using the NOCO GENPRO On-Board Battery Charger - AC to DC - Waterproof - 4 Bank - 12V - 40 Amp # NOC84FR, which will charge batteries rated for up to 230 amp hours. You can also add the NOCO AC Port Plug with Extension Cord - 16" Long # 329-GCP1 to this setup to allow you to plug an extension directly into the coach since this setup will likely be stored in a cargo hold, out of the elements. For your engine batteries,...

  • Battery Chargers to Maintain Battery on 2007 Arctic Cat ATV with Winch
  • If your Arctic Cat 350 ATV has a snow plow with powered winch lift and you are having trouble with having enough power to both operate the plow and start the ATV from the one battery I suggest you consider keeping the ATV on a maintenance charger like the CTEK MULTI US 7002 12-Volt Universal Battery Charger with Pulse Maintenance # CTEK56353. This AC-powered charger will keep your ATV battery topped off but won't undercharge or overcharge since it automatically switches to pulse-maintenance...
