What is a Sealed Lead Acid Battery?
Sealed Lead Acid batteries are a popular type of lead-acid battery in which the electrolyte is suspended in a thin fiberglass mat that is situated between the lead plates.
The composition of Sealed Lead Acid is completely sealed. Unlike flooded lead-acid batteries, the electrolyte cannot escape the battery case.
Pros and Cons of Sealed Lead Acid Batteries
Due to the sealed nature of Sealed Lead Acid batteries, they have some key benefits over flooded batteries:
Maintenance-free
Can be mounted in any orientation
Resistant to vibration
Resilient in cold temperatures
Higher charge/discharge rates than gel or flooded batteries
Sealed Lead Acid batteries come at a higher cost than flooded lead-acid batteries, but the trade-off is a battery that is more flexible and easier to install—all without the routine maintenance required of flooded batteries.
Consider flooded lead-acid batteries if you want the most cost-effective option available and are willing to perform regular upkeep on your battery bank. For convenience and versatility, Sealed Lead Acid batteries are a fantastic choice for hassle-free solar storage.
