A sealed Gel Battery is a regulating valve, maintenance-free, lead-acid battery. Gel batteries are extremely durable and versatile. This type of battery produces very little smoke and can be used in poorly ventilated areas.

　　How does Sealed Gel Battery work?

　　A valve-regulated lead-acid battery regulated by a rubber valve, in which a predetermined amount of electrolyte is mixed with sulfuric acid and silicon fume. This chemical reaction produces fixed gel-like clumps that give these batteries their names. Gel batteries are actually maintenance-free because they use a one-way opening valve to recombine the internal gas into water, so there is no need to check to fill up with distilled water or monitor the water level. Gel batteries are extremely durable and versatile. They can be safely installed in well-ventilated places. Because their gas/flue gas production is very low (almost zero), the restrictions are limited, which means you can even install batteries in your home.

　　Choose the charge controller that suits your Sealed Gel Battery carefully

　　Special care should be taken when choosing a charger for Sealed Gel Battery, as they will charge at a lower voltage. Overvoltage can cause malfunctions and reduce performance. Sometimes, the term GEL battery usually refers to Sealed Maintenance-Free Battery and is marked as a setting on the charge controller. This may cause confusion and may lead to incorrect charger selection or incorrect settings during charging. If other charging methods such as alternators are used, appropriate regulators must be installed to maintain control of the charging voltage. The general charging voltage range of the battery is 14.0 volts to 14.2 volts, and the floating voltage range is 13.1 volts to 13.3 volts.
