Aircraft Battery

SS28300 – is the analog of the Russian 12SAM28 battery.
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 self-resealing, 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 widely used for on-board aircraft starting and for providing emergency backup in case of generator failure and proves to outstand its Russian analog 12SAM28 in many characteristics.

Application

The SS28300 battery is available with or without the battery box in various configurations depending on the requirements of the specific helicopter/aircraft:
Number of batteries per helicopter or aircraft
SS 28300 MI     MI 8 Helicopter      6 Batteries 
                          MI 17 Helicopter    3  Batteries
             
SS 28300 AN     AN-22, AN-24, AN-26, AN-32 Aircraft     3 Batteries 
SS 28300 IS     Iskara Aircraft     2
The SS28300 battery is also suitable (with minor modifications of battery box) for use on
*MI-14
*AN-22, AN-24, AN-26
Silver Start batteries are delivered fully charged and are ready for immediate use. These batteries
are a replacement for the Russian 12CAM28 dry charged lead acid battery.
