If you ask a novice what a vehicle battery’s limitation is, you may expect the most common answer—they die over time and must be replaced. Vehicle batteries are expensive. Therefore, what if they can be repeatedly charged when they are discharged? This is precisely how deep-cycle batteries are designed. They are used in golf carts, RVs, solar power systems, 4WD vehicles, and boats.
How is a deep-cycle battery different from regular batteries?
Though deep-cycle batteries look very much like car batteries, they are quite different. Made from lead, they are designed to sustain power for long. They are required to be recharged only after they are discharged for over 80%. However, if you wish to extend the battery’s life, it is best not to let it discharge below 45%.
Different types of deep-cycle batteries:
There are five different types of deep-cycle batteries:
1. Flooded deep-cycle batteries:
This is the most common and inexpensive type of deep-cycle battery. However, it demands regular and frequent maintenance. Car batteries of this type must be filled with distilled water frequently to function at an optimum level.
2. Sealed deep-cycle batteries:
These car batteries are expensive but maintenance-free. They do not need to be replenished with distilled water at regular intervals.
3. Absorbed Glass Mat (AGM) batteries:
AGM batteries comprise a glass mat that can absorb the electrolyte. Therefore, these car batteries are known as absorbed Glass Mat batteries. Due to their make, the electrolytes are evenly distributed throughout the battery. As a result, these 4WD batteries significantly improve the vehicle’s performance. The batteries have a longer lifespan than flood and sealed deep-cycle batteries.
4. Gel batteries:
Gel car batteries are a refined version of deep-cycle batteries. They contain a gelling agent that thickens the electrolyte and makes it more viscous. This technology works wonders in preventing fluid leakage from the battery, one of the most common reasons for battery damage.
5. Lithium-ion batteries:
Lithium-ion batteries are the latest addition to the deep-cycle battery league. They are far more advanced than traditional car batteries made from lead and acid. These batteries weigh less and have a longer lifespan. Even when discharged deeply, they can withstand damage. Due to their sophisticated design, they cost more than lead-acid car batteries.
How are deep-cycle batteries made?
Flooded and sealed deep-cycle batteries are made of lead plates and electrolytes. Lead plates generate electricity by reacting to the electrolyte, which is a mixture of sulfuric acid and water. This fluid is a catalyst for starting and retaining chemical reactions between lead plates. The lead plates and the fluid are covered with a case that protects the battery from damage and holds the components in place.
Things to consider while buying a deep-cycle battery:
First and foremost, determine the purpose of battery usage. If you wish to use it in stationary or level equipment, a flooded deep-cycle battery is the best choice. They are easily available and cost less. This battery requires frequent charging and water. As it uses liquid electrolytes, it is required to be used upright only. Therefore, it should be used in stationary or level equipment like forklifts and renewable energy storage. In variable conditions like boats and RVs, an AGM battery is an ideal choice.
How to maintain a deep-cycle battery?
Though deep-cycle batteries can be repeatedly charged, they must be maintained regularly to extend their life. After charging the battery, one must monitor the fluid level and voltage. This inspection can be performed using tools like a hydrometer and a DC voltage meter.
A reliable place to purchase 4WD batteries and car batteries:
