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 SS28300 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.
Application
The SS28300 battery is available with or without the battery box in various configurations depending
on the requirements of the specific helicopter/aircraft:
