Lifeline GPL-4CT review

The Noteworthy Feature of Lifeline Marine GPL-4CT AGM Battery Review

Lifeline AGM batteries review will be incomplete without mentioning its awesome features. It pretty obvious that you want to make sure the battery has all required feature. Thus, the Company never compromise with the quality. Let’s see, some remarkable features of this 6v AGM deep cycle battery.

Mil-Spec Certified

The very first feature we like to introduce is it is U.S. Mil-Spec certified. So far it can endure severe vibration and shock. Thus, it works great from extreme heat to polar ice. However, Mil-Spec is a military standard by the U.S. Department of Defense. Furthermore, Mil-Spec is approved when the item meets a certain requirement.

Unrivaled Safety

The next noticeable feature we like to introduce is its unrivaled safety feature. Not only that, it gives incomparable safety if it has over-charging situations.  Not only that, it produces below 2 percent hydrogen gas by volume.  Point to be noted, 4.1 percent is needed for flammability in the air.

Impressive Discharge Rate

Lifeline gives nearly 1,000 cycles at the discharge rate of 50 percent. Thus, the rate is crucially higher than the wet cell. On the other hand, the gel battery provides nearly 300 to 450 cycles. Another feature we like most is its faster recharge rate.

Long Lifespan

Another great feature of this Lifeline AGMs is its longer lifespan. Thus, the typical lifespan of this battery is 5 to 8 years. If you can maintain it properly, it can last up to 10 years. However, this range is quite higher than any other competitor.

No Sulfuric Acid Leaks

Where most of the battery is made up of the sulphuric acid solution, this battery is out of it. Sulphuric acid is highly toxic as well as corrosive. Therefore, you don’t have to handle the leaking problem. That means more power in the same space. However, keep in mind; sulfuric acid leaks need extreme care for safety reasons. Meanwhile, the sulfuric acid battery has to keep away from pet and children. So this no acid clean up feature is surely a big advantage.

Amazing Warranty Offer

Lifeline offers one of the excellent offers in the industry right now. It comes with a one-year free replacement. At the same time, it comes with a 5-year pro-rated replacement. Besides this, the company is a reputed position. Thus, Lifeline serves its batteries as OEM over the U.S. as well as international companies. On the other hand, Lifeline never compromises quality.
