The two most frequent causes for RV battery collapse are undercharging and overcharging.
Undercharging is a consequence of batteries being discharged rather than completely recharged between bicycles. If a Vapcell 18650 battery isn’t recharged the sulfate substance that attaches to the discharged parts of these plates starts to harden into circles. Through the years this sulfate can’t be transformed back into active plate material and the battery has been destroyed. This also happens when a battery stays discharged for an elongated time period, like during memory. Sulfation is the primary cause of battery failure. The next top cause of battery failure is overcharging. Overcharging batteries leads to severe water reduction and plate corrosion. With that said let us look at how to properly keep your RV batteries.
Before we speak about keeping the batteries we must discuss battery safety. Lead acid batteries contain sulfuric acid that’s very corrosive and can cause severe burns or even blindness. Along with also the hydrogen gas that batteries create if they are charging is quite volatile. When you operate around batteries you will need to use goggles and gloves, then remove all jewelry and don’t smoke or use any open flames.
Caution: If you inadvertently get battery acid on your skin, then flush it with a great deal of water and if it gets into your eyes flush with low pressure water for 15 minutes and call a physician.
When you place the RV in long-term storage it is a good idea to remove the batteries and place them in storage also. This is rather straightforward to do. The very first thing we would like to do is inspect the batteries for almost any obvious damage. Any fluid around the battery might be a sign that electrolyte is leaking out of the battery. A leaking or damaged battery ought to be replaced promptly. At any time you eliminate any battery always make sure you remove the negative cable or terminal, then the cable.
