Expert Answers about Battery


  • Parallel Batteries Versus Batteries Wired in Series
  • If two batteries are wired in parallel, the positive terminals of each battery will be connected together, as will the negative terminals. Assuming both batteries are 12 volt, you'll have a 12 volt output but there will be more capacity. If the batteries are wired in series, the positive terminal of one battery will be connected to the negative terminal of the other. This would double the output of the batteries, assuming each battery is a 12 volt, wiring the batteries in series would...

  • Can You Connect The NOCO GENPRO Battery Charger To Multiple Batteries in Parallel?
  • The NOCO GENPRO On-Board Battery Charger # NOC74FR can charge up to 3 different battery banks. It cannot connect to different batteries in a parallel or series bank of batteries. By connecting to one of the batteries in your parallel bank it will charge all of the batteries at once. If you had it connected to multiple batteries in the same bank it will not charge correctly as it will misinterpret the charge it sees as battery voltage.

  • How Does Battery Charger Work With 2 Batteries Run In Parallel On Fifth Wheel Trailer
  • When charging batteries that are wired in parallel or series, the charger will charge the first battery it is attached to and that battery will start slowly charging the second battery while the charger replenishes the first battery. It really is much faster if you charge the two batteries separately.

  • Do Trailer Batteries and Car Batteries Have Different Terminals
  • Auxiliary batteries, which are often used for trailers, and automotive batteries are both 12 volt batteries but there are many different types of 12 volt batteries and they are different in a number of regards, including amp hour ratings. In regards to their connections, they will both have positive and negative terminals, though I would not be able to tell you with any type of certainty that your much older battery charger is capable of working with modern batteries. I very strongly recommend...

  • When Replacing 12-Volt Batteries With 6-Volt Are They Run In Parallel Or Series
  • Your system could be 12 volts with the batteries wired in parallel or it could be 24 volts which requires wiring in series. If you have a 24-volt system you will need a quantity of (4) 6-volt batteries. If you have a 12 volt system and you are using 6-volt batteries you will need to run the batteries in series. You will need to run a wire from the positive post on one battery to the solar panel. Then run a jumper form the negative post of that battery to the positive post of the second...

  • What is the Life Expectancy of the Battery in the Swift Hitch Wireless Backup Camera 04928
  • I checked into this with the manufacturer, and the battery in the camera portion of the # 04298 wireless backup camera system is actually replaceable. The battery is sealed inside the camera, but can be accessed. The new battery would need to be soldered into the assembly, so it is a bit more tricky to replace than the battery in the monitor but it is doable. When I asked about the lifespan of the battery, my contact at Swift Hitch said that although they have on occasion had to replace...

  • Using 7-Way Trailer Connector 12-Volt Accessory Circuit to Maintain Battery on Dump Trailer
  • If you have read our previous responses regarding the use of the 12-volt accessory circuit from the 7-way, then you know that the circuit can be used to maintain, but not charge a depleted trailer-mounted battery. We typically recommend using a battery charger like the # CTEK56353 CTEK Universal Battery Charger to recharge a depleted battery. The 12-volt accessory circuit should already be fused (or if the 7-way was installed aftermarket, protected by a 40 amp inline circuit breaker like...

  • Can I Power Lights On My Horse Trailer With a Small Battery Installed on Trailer
  • Yes, you would be able to install a battery on your horse trailer, and power the lights when the trailer is not connected to the truck. What you will want to do is run the power wire, typically the Black wire, on the trailer connector and connect it to the positive battery terminal. You will want to ground the battery to the trailer frame, and then run the power wires for the lights to the positive battery terminal. Each light assembly should be grounded to a clean metal surface. You...

  • Will Camper Battery Connected To Truck Trailer Connector Drain Truck Battery
  • The 12V accessory line on the 7-way connector on your truck which is the pin in the 1 o'clock position when looking at the front of the 7-way, will not charge the battery in your camper. It can maintain the charge of the battery when connected. It is always a good practice to disconnect the trailer from the vehicle to prevent the battery on your truck from discharging. If you have the camper connected to the truck while you are driving or while the truck engine is running, it will not...

  • How To Connect A CTEK Charger To Batteries Wired In Parallel
  • When connecting the Ctek Charger # CTEK56353 to batteries wired in parallel, the positive from the Ctek would go to positive on battery 1. The negative on the Ctek would go to the negative of battery 2. The charger would charge the first battery first, then slowly charge the second while the charger replenishes the first battery.

  • Will 12 Volt Batteries Charge at Same Rate Using Battery Charger
  • Two 12 volt batteries wired in parallel will not necessarily charge at the same rate when using a battery charger such as the OptiMate 7 Select Smart Battery Charger - AC to DC - 12V - 10 Amp # MA57JR. It depends on the amp hours of the batteries, and if you have different amp hours, the larger one will charge/discharge slower. But if they are the exact same battery, and both are charged equally, then it will be pretty close to the same rate. I have added a link below to our entire selection...

  • Can Breakaway Kit Battery Be Charged from Main Trailer Battery Without Depleting It
  • It is permissible to have your trailer breakaway and water pump wired in the way you describe - under certain circumstances. As long as your water pump battery is substantially larger in current capacity than the breakaway battery, and as long as BOTH batteries are in good condition and fully charged before you head out, then the 12V maintenance charge from your vehicle 7-way wiring harness should be able to maintain both batteries without either becoming depleted. I suggest you apply...

  • Preventing Trailer Mounted Battery from Draining Battery on Tow Vehicle
  • A trailer mounted battery is typically maintained by the 12-volt accessory circuit from the 7-way trailer connector. If the accessory circuit on your 7-way is live even when the ignition is shut off, it is possible that the battery on your truck could be discharged. If shutting off the ignition shuts down that circuit, you will have no worries. If the circuit is live with the ignition off, you can unplug the trailer, disconnect the 12-volt accessory circuit from the trailer mounted battery,...

  • Why Should You Disconnect The Battery When Flat Towing
  • The general reason a battery needs to be disconnected for flat towing is because there are certain functions that need to be disabled to prevent your vehicle's battery from draining. You wouldn't want to get to your destination and unhook and then have a dead battery and not be able to move your vehicle. You should always follow your vehicle's manual to the letter to prevent damage to your vehicle. If you want to install a switch to make disconnecting and reconnecting the battery simple...
