Demands for Power

In case your power demand is higher than average then there is a high chance that these won’t last long. There is a strain on the battery to meet the demand for your power. So, it is natural the battery is going to drain quickly.

In other cases, there is a “coach” that is meant for recreational vehicle living rooms. Therefore, these types get your steady currents for more duration. Finally, there is an inconvenience when you switch the role of batteries.

Tips to Increase RV Battery Life

  • Correct Charging; You need to make exceptionally sure that the batteries are charging correctly like putting boundaries beyond 40 and reaching 100. So, you need to make sure that they start charging once they reach 40 percent.
  • Parasitic Loads; Parasitic loads are electronic devices that can drain the power in case your RV is turned off. When devices are running when the engine itself is off can result in a dead one. Further, you can go for the surge protector strips of power that can ensure you that the devices if off when it needs to be.
  • Heat and Humidity; the temperature can affect life. Hot weather can result in the water of batteries running dry quickly. When you are using distilled water, it can result in overheating, and the water level drains slowly.
  • Fluctuation of temperature; fluctuations in the environment can cause issues of heat, moisture, and more. So, you need to make sure that the batteries are present in the correct environment while a steady RV needs to be at a balanced temperature.
