VRLA Battery 12V 4.5AH | Dimension: 90x71x101x107mm
GRANKIA FG4.5-12 small valve regulated lead acid battery 12v 4.5ah can be used in enclosed and indoor environments without leaking or maintenance, providing a superior performance. The lead–acid battery consists of two electrodes submerged in an electrolyte of sulfuric acid.
The valve regulated lead acid battery 12v 4.5ah consists of electrodes of lead metal (Pb) and lead oxide (PbO2) in an electrolyte of about 37% sulfuric acid (H2SO4).
Note:
Yes, it provides the same 12 volts DC to any vehicle that uses a 12 v battery. It’s just a sealed paste and has the same voltage ranges as most 12 volt batteries. It’s still LEAD chemistry.
Yes for the most part an AGM is a drop in replacement for your standard Lead Acid Battery. The charging voltages are almost identical.
Basically, an AGM battery will always have a flat top, and only the negative and positive terminals of the battery will be sticking out.
