At an average ambient temperature of 25 º C, a 12-volt gel or AGM battery usually lasts up to six years. Even after five to six years of float charging voltage, the battery tends to retain 80% of its initial capacity.
Deep Cycle Batteries: Endurance Champions in the Battery Realm
Deep cycle batteries are like the long distance runners of the battery world. Deep cycle batteries have a place in a variety of applications because of their ability to provide stable power over long periods of time. But what exactly is a deep cycle battery and how is it different from other types of batteries?
A deep cycle battery is a type of battery that is specifically designed to be discharged to a significant portion of its capacity, then recharged and reused. This is in contrast to a starter battery, such as a car battery, which provides a high current for a short period of time to start the engine.
Deep cycle batteries can be further categorized into flooded lead-acid batteries, gel batteries (also known as colloidal batteries), lithium-ion batteries and absorbed glass mat (AGM) batteries.
The Lifespan of Different Types of Batteries: A Comprehensive Guide
How Long Flooded Lead Acid Batteries Last?
Flooded lead acid batteries can last up to 8 years with proper maintenance. They typically offer 300 to 1,000 charge-discharge cycles, with a depth of discharge of around 50%.
How Long Gel Batteries Last?
Gel batteries typically last around 10 years, longer than flooded batteries. They provide between 500 and 5,000 cycles, depending on discharge depth and battery quality.
How Long Lithium-ion Batteries Last?
Lithium-ion batteries, newer to deep cycle use, boast an impressive lifespan of up to 15 years. They offer 2,000 to 5,000 cycles at up to 80% depth of discharge.
How Long Absorbed Glass Mat (AGM) Batteries Last?
AGM batteries are known for being maintenance-free and lasting between 7 and 10 years. They usually deliver around 600 to 1,000 cycles, depending on the discharge level and how well they are managed.
Gel Battery VS Lithium
Gel batteries are more affordable than lithium-ion batteries. Gel batteries typically provide 1,500 to 2,000 cycles, while lithium-ion batteries can offer up to 6,000 cycles, depending on the depth of discharge.
