Overcharging can lead to excess heat and fluid loss, while undercharging can cause sulfation, which is the buildup of lead sulfate crystals on the battery plates. Maintaining a charge voltage between 14.4 to 14.8 volts is ideal for most lead-acid batteries (Borrelli et al., 2020).

  • Cleanliness: Keep the battery’s surface clean and free of grime and corrosion. Dirt and corrosion can create electrical resistance that impairs performance. Cleaning terminals and connections with a mixture of baking soda and water can restore conductivity.

  • Temperature management: Batteries should be kept at an appropriate temperature, ideally between 32°F and 85°F (0°C and 29°C). Extreme temperatures can affect battery efficiency and lifespan. For example, cold temperatures can slow down reactions in lead-acid batteries, while high temperatures can accelerate evaporation and damage internal components (Reddy et al., 2019).

  • Water levels: For batteries that require maintenance, regularly check the electrolyte levels. Keep the levels between the minimum and maximum markers. Ensure that distilled water is used to top up as other types of water can introduce impurities.

By implementing these maintenance practices, you can enhance the performance and longevity of your overland battery, ensuring it remains reliable for all your adventures.
