Silver Start on-board aircraft batteries employ Pure Lead-Tin, Thin Plate technology for high-performance. These Valve Regulated Lead Acid (VRLA) batteries are designed using Absorbent Glass Mat (AGM) separators that render the batteries spill-proof for aerobatic use. The use of AGM separators in combination with selfresealing, pressure-regulating valves and a starved electrolyte design enable recombination of gases generated during normal operation. This eliminates the need for electrolyte top-up.
The SS28300MI is a 24V, 28Ah@5hr battery consisting of two 12V blocks connected together in series.
This battery is used for on-board aircraft starting and for providing emergency backup in case of
generator failure.
