Deep Cycle Marine/RV Battery The GPL-U1T is a high performance, Mil-Spec, AGM battery, produced in the United States. Due to the Lifeline Battery’s quality construction, it has an industry leading 2% per month self discharge rate at 77°F (25°C), compared to 10%+ for conventional batteries. Coast Guard approved, DOT Haz Mat Exempt, and longer lifespans than conventional batteries. Warrantied installations include marine, yacht, and other seafaring applications.


Lifeline GPL-U1T AGM Battery

The Lifeline GPL-U1T is a high performance, Mil-Spec, AGM battery, produced in the United States. The U1 battery is also found in the popular Mazda Miata MX-5 two-seater sports car. Due to the Lifeline Battery’s quality construction, it has an industry leading 2% per month self discharge rate at 77°F (25°C). These batteries off gas only 2% by volume under normal operating conditions, again, industry leading. No sulfuric acid leaks, no acid clean up, and more power in the same space when compared to conventional batteries. Lifeline GPL-U1T AGM Battery

Specs at a Glance:

  • 325 Cold Cranking Amps
  • Reserve capacity – 33Ah @ 20 Hour rate
  • Discharge Minutes – 50 min@ 25 Amps, 93 min@ 15 Amps, 185 min@ 8 amps
PL-U1T Charging Instructions and Voltages:
  • Bulk Charge Voltages: 14.20 – 14.60
  • Absorbtion Charge Voltages: 14.20 – 14.60 volts
  • Float Charge Voltages: 13.10 – 13.40
The GPL-U1T is designed for charging amperages up to 82.5 amps or 250% of the rated Amp Hour Capacity due to low battery internal resistance. As the preferred AGM battery choice of more than 150 OEM’s around the world, Lifeline is the Best Battery you can Buy! Lifeline Batteries are perhaps best known in the marine industry by those with mission critical applications like professional anglers, long distance cruisers and yacht captains seeking value and reliability. These Lifeline Battery owners consistently experience a working life-span between 5-8 years for their AGM batteries. Often operating in extreme latitudes, from equatorial heat to polar ice, the weather is no match for the toughness of a Lifeline Battery. As reported back to us directly from Yacht manufacturers, marine distributors, and end users alike. Lifeline Batteries function to stickered specifications while operating in the harshest of equatorial climates. As our customers present us with applications nearing the poles, they find comfort knowing that our batteries are not damaged by extreme subzero temperatures either. Lifeline Battery manufactures numerous sizes of batteries to produce reliable power for any application, industry leading reserve capacities, two to three times the life-cycles and a virtually non-existent defect rate. Superior Construction Aircraft class cell construction; lowest internal resistance that provides high repeated cranking current. Unmatched Life-Cycles When discharged to the BCI recommended 50%, Lifeline batteries provide nearly 1000 life cycles, which is significantly more than other technologies. Other flooded and gelled batteries fall between 300 to 450 life cycles at 50% discharges. Rapid Recharge Lifeline Batteries facilitate a significant increase in recharge rate, with amazingly high current limitations when you properly regulate the charging voltage. Customers charge 100ah batteries with 500amp chargers routinely. Low Self Discharge Much better charge retention rate when compared to flooded and gelled technologies. Lifeline Batteries self discharge around 2% per month vs. 10% for other batteries. Maintenance Free With proper charging, Lifeline Batteries require no maintenance. Lifeline Batteries do NOT accept addition of water nor do they corrode their surroundings. Safety First During normal charging conditions there is no dangerous gassing. Mil-Spec Lifeline battery construction has passed extensive military shock and vibration requirements. Eliminate Dangerous Gassing Lifeline provides safety even during severe overcharging as the batteries produce less than 2% hydrogen gas by volume (4.1% is required for flammability in air). Long Service Life Lifeline batteries currently installed in Marine and RV applications are providing a life span ranging from 5 to 8 years under routine use. Daily and intensive applications also see 3-8 years of use depending on depth of discharge. Solid Warranty Lifeline Batteries offers one of the best warranties in the industry with our 5-year pro-rated and a one-year free replacement.
