Deep cycle batteries, including the 120Ah deep cycle solar battery, come in various types. Each type is based on the technology used in its design, as this caters to specific energy storage needs. The three of the most common battery types include lithium-ion, lead-acid, and AGM gel.
Lithium-ion batteries are known for their high energy density. They also have a longer lifespan than other types of batteries. A lithium 120ah deep cycle battery can last up to 10 years or more with proper care and maintenance. This battery type can be discharged up to 80% without causing significant damage to the battery. Therefore, it can be cycled multiple times daily. This makes it ideal for off-grid solar systems that may require constant daily use.
Lead-acid batteries are traditional deep cycle batteries commonly used in solar applications. There are flooded lead-acid batteries that require maintenance to ensure optimal functionality, such as regular checks and water additions. However, they are also less expensive than lithium-ion batteries. There is also sealed lead-acid (SLA) batteries, such as VRLA batteries. These are maintenance-free and easier to install in different applications.
AGM Gel
Lastly, there are absorbed glass mat (AGM) and gel lead-acid batteries that are also widely used in solar applications. AGM batteries have their electrolyte suspended in fiberglass mats. While gellers have their electrolyte mixed with silica powder to form a jelly-like substance. Both these battery types offer better resistance to shock and vibration than SLA. AGM and gel batteries are more spill-proof and have a similar depth of discharge (DoD) of about 50–60%.
The 120ah deep cycle battery can be used to store energy harvested from the sun using solar panels. This is because it is designed to provide a steady amount of power over extended periods. This distinguishes it from primary batteries which are designed to release large amounts of power over short periods. The 120Ah rating indicates that the battery can provide 120 amperes of energy for one hour or proportionally longer.
The battery can handle about 3000–5000 charging cycles, depending on the battery used. This is common, especially for lithium-ion batteries. A long cycle life means the battery will last for many years of charging and discharging before its capacity significantly decreases.
The deep cycle battery is also designed with high resistance to extreme temperatures.
AGM and gel lead-acid batteries can operate efficiently in wider temperature ranges than flooded lead-acid batteries. This helps the battery maintain its performance even in harsh environmental conditions.
A deep cycle battery is designed with low self-discharge. Lithium-ion and AGM batteries typically only lose about 2–5% of their charge monthly when not in use. Even flooded and SLA batteries have a higher self-discharge. This can allay concerns that the battery will lose its charge while it is not in use.
The 120ah solar battery can also be paired with inverter systems of different wattage ratings. This is as long as the battery is sufficiently connected to the solar charger. For example, a watt-manage inverter helps to prevent excessive power draw from depleting the battery too quickly.
Following manufacturers’ instructions on the right way and how to care for the deep cycle battery will ensure long-lasting functionality. This helps the battery to operate as intended while preventing accidents and hazards.
One of the battery’s primary uses is to store excess energy from solar systems for later use. It does this by recharging with renewable energy from the sun during the day. Then, it will discharge the stored power at night or when the solar system is not generating sufficient power. A deep cycle battery is important in off-grid and backup power systems. This is because it provides a reliable source of electricity when there is no availability of direct access to the grid.
The battery can power different appliances, such as lights, refrigerators, and water pumps in residential and commercial settings. This makes sure the essentials continue to function when there is a power outage. The battery is also used in off-grid applications like RVs, boats, and remote cabins. This provides a portable and self-sufficient power source for different uses, such as running water and charging electronic devices.
The 120ah battery can work with inverters to produce AC power from the stored DC power. This allows users to power devices that require alternating current power.
Buyers need to check a myriad of factors when purchasing a 120Ah deep cycle solar battery. This ensures they get the correct battery that meets their clients’ needs.
One of the factors is the battery type. Buyers should stock lead-acid and lithium-ion batteries, as these are the most popular battery types. Although more clients prefer the lithium-ion battery. This is especially for customers who require a low-maintenance option with a longer lifespan and higher DoD.
For clients who want a more budget-friendly option, buyers can get flooded lead-acid and SLA batteries. They are more affordable even though they need maintenance and do not last as long. Buyers also need to get batteries from reputable manufacturers to ensure they have high-quality products. They should also ensure the batteries have certification. This includes compliance with international safety standards by organizations such as IEC and UL.
Buyers should also consider stocking batteries with features that enable easy installation and use. These include maintenance-free designs, built-in handles, and battery management systems. Customers will also prefer batteries with extended warranties. This is because it indicates the manufacturer has confidence in the product’s durability and reliability.
Buyers should buy deep cycle batteries that support different temperature ranges. This caters to clients in diverse geographical regions. Those that can withstand hot and cold temperatures will likely appeal to customers. These are particularly in the regions that experience extreme environments.
Lastly, buyers need to consider shipping options and the costs of the 120Ah deep cycle solar batteries. They should get reasonable deals so they can pass on the savings to their customers. Since solar batteries are heavy, they will increase the shipping costs. So, buyers should get a supplier who offers them free or discounted shipping.
A1. Customers can increase the lifespan of a deep cycle battery 120ah by practicing good charging habits. They should avoid fully discharging the battery and recharge it as soon as possible once it reaches a 50% depth of discharge. Customers should also ensure their solar system does not overcharge or undercharge the battery. Doing this will ensure the battery maintains optimal functionality for many more years.
A2. Customers who want longer-lasting batteries that require little to no maintenance will prefer lithium iron phosphate (LiFePO4) 120Ah deep cycle solar batteries. One of the biggest advantages of this type of battery is its long lifespan. This can go up to 10 years or more with good care. It is also less expensive when spread over its long life. It allows for daily cycling without significant degradation.
A3. If a 120Ah deep cycle solar battery will not hold charge, customers should first confirm the battery is not old and has gone past its cycle life. If they have been using it for more than five years, it may be time for a replacement. If the battery is relatively new, customers should check if there are defective components or connectors. They should also inspect the battery for signs of damage or corrosion. If the 120Ah deep cycle battery is not charging, customers can try using a smart charger to determine if the battery is sulfated.
A4. Yes, the 12 volt deep cycle battery is ideal for off-grid solar power systems. It stores excess energy harvested from the sun and then releases it when the system does not generate sufficient power. It provides reliable power for various applications, including homes, RVs, and boats.
A5. Yes, a 120Ah deep cycle solar battery can be used in an uninterruptible power supply to provide backup power during outages. However, customers should ensure the battery is compatible with their UPS system. This is by matching voltage requirements and adjusting the charging settings as necessary.
