Main Ship Batteries

Main Ship Batteries - Hawker "Pure Lead" Technology

Securaplane Sealed Lead Acid (SLA) Main Ship Batteries have technology that beats NiCad, Lead-Calcium and Lead-Antimony in every category of performance. They can ultimately save operators hundreds, if not thousands, of dollars annually.

Securaplane is Master Distributor and Design and Certification Authority for EnerSys Hawker brand batteries for commercial and business aviation in the USA. Hawker Main Ship Batteries offer significant performance enhancements compared to other sealed lead acid and Ni-Cad batteries:

99.99% pure lead construction for enhanced life and performance.
Batteries are shipped fully charged and ready to install.
True no-maintenance battery.
Hot and cold performance far exceeding that of any other aviation battery.
Unsurpassed cranking power.
Battery monobloc replacement at significantly less than the list price of a new battery.
Certified as non-spillable and may be shipped as non-hazardous material via ground or air.

How do Securaplane's batteries stack up against other battery technologies?

Battery Type Comparisons: Advantages of Hawker "Pure lead" technology

Comparison Category	NiCad	"All Other SLA" - Lead Calcium etc.	SLA - Hawker "Pure Lead"	$$ SLA vs Ni-Cad (Annual Savings)


Battery Lifespan / Reblocking	Cells replaced (3 / yr)	Lowest lifespan; < 1 year typical	3rd yr Reblocking; Lower battery life costs	$1,387
Maintenance Reqs. And Cost	Deep cycling, fluid checks, battery cell replacement on a regular basis	Battery replacement / yr	Capacity check only until Reblocking in 3rd yr	$1,600 to $2,600
Cold weather performance Lower limit for engine start:	-10º C / -14ºF	-20º C / 32ºF	-40º F / C
Starting power	> power than Pure Lead	1/3 power of Pure Lead	Other Lead < SLA < - Ni-Cad. Lowest Internal Resistance
Recovery after full discharge	Full service required	Unable	Recover 97% capacity
Battery Recharge time	Identical to Pure SLA in rate of charge acceptance. Risk of thermal runaway at high charge rates	Slower than Pure SLA in rate of charge acceptance. Risk of thermal runaway & significant outgassing & electrolyte expulsion at high charge rates	Low internal impedance permits very efficient and rapid recharge. Achieve 90% charge recovery in less than 60 minutes from discharged condition.
Storage Life, charged (25º C)	1 month	5 months	30 months	$5,000+
Shipping Requirements	Hazardous materials, spillable. Ground shipping only, ships discharged and shorted.	Non-hazardous, non spillable, ships fully charged.	Non-hazardous, non spillable, ships fully charged.	$2,500
Environmental concerns	Cadmium requires special disposal	Lead is easily recycled	Lead is easily recycled
Weight	10 lb. < SLA	3 lb. < SLA	10 lb. > Ni-Cad	($250)
