VRLA Battery 12V 33AH | Dimension: 196x130x155x167mm
GRANKIA FG33-12 smf valve regulated sealed battery 12v 33ah is constructed with lead calcium alloy and absorbed glass mat AGM technology. It allows a completely maintenance-free and high-performance operation. Fiberglass mat separators and high cell compression extend battery life by delivering superior vibration resistance from the most extreme conditions.
The valve regulated sealed battery 12v 33ah offers excellent performance in a wide range of applications including security and fire systems, medical devices, emergency lighting and UPS systems.
Unlike flooded rechargeable batteries, sealed rechargeable batteries do not contain a liquid that will spill out if the battery breaks. Instead, sealed rechargeable batteries hold only enough liquid to allow the electrolytes to flow.
Since sealed batteries are spill-proof, have better power density and good performance in cold weather than flooded batteries. Hence, only sealed batteries are used in car batteries. Among the two types of sealed batteries, the AGM type is more preferable over a gel type. And all car manufacturers use AGM batteries.
Sealed Lead Acid batteries fall under the category of rechargeable batteries and if they are ignored, not charged after use, not charged properly or have reached the end of their intended life span, they are done. If it’s completely dead, it’s gone and you need to find a replacement.
