Undercharging occurs when the battery is not allowed to return to a full charge after it has been used.Easy enough, right? But if you do this continuously, or even just store the battery with a partial charge, it can. While you certainly don't want to keep your battery in an undercharged state, overcharging is just as bad.Continuous charging can: 1. cause corrosion of the positive battery p. Because water is lost during the charging process, damage can occur if that water is not replenished. If the electrolyte level drops below the tops of the plates, the damage can be ir. Not only can your battery have too little water to function properly, but it can also have too much. Overwatering can cause the electrolytes to become diluted, which results in diminis. The issues surrounding over and under charging as well as over and under watering can be a fine line to walk. It's really just about finding the sweet spot. Most battery man.

A lack of maintenance or improper maintenance is also one of the biggest causes of damage to lead-acid batteries, generally from the electrolyte solution having too much or too little water. All of the ways lead acid can be damaged are not issues for lithium and why our batteries are far superior for energy storage applications.
(See BU-705: How to Recycle Batteries) The sulfuric acid in a lead acid battery is highly corrosive and is more harmful than acids used in most other battery systems. Contact with eye can cause permanent blindness; swallowing damages internal organs that can lead to death.
When you use your battery, the process happens in reverse, as the opposite chemical reaction generates the batteries' electricity. In unsealed lead acid batteries, periodically, you'll have to open up the battery and top it off with distilled water to ensure the electrolyte solution remains at the proper concentration.
Lead-acid batteries need water to keep the electrolyte solution right. Too much water can dilute the electrolyte, cause spills, and damage the battery. Having the right water levels is key for the battery to work well and last longer. How often you need to check the water depends on how you use the battery and where you live.
Applications that have these profiles are solar energy storage and energy storage for off-grid power. Two of the most common mistakes that lead to lead-acid battery damage involve charging — or lack thereof. Some owners discharge their batteries too deeply, permanently altering their chemistry and function.
The only applications that a lead acid battery is operated for longevity are when they are discharged for short periods (less than 50 percent) and then fully recharged. One application that fits this need is vehicle starting. Applications for stationary storage can have stratification and sulfation problems.
