More on sealed batteries maintenance-free

Solar panels are better today than ever. This also applies to the devices that regulate and protect them, like batteries for example.

 Batteries are the primary source of storage for standalone (off-grid) systems, but they also provide emergency power for systems connected to the network (grid-tied with a solar battery backup). Installing a network-connected system with a backup solar panel also makes it possible to store excess energy for later.

Sealed maintenance-free batteries are hermetically sealed and designed to provide higher levels of energy in renewable energy applications. They are designed for high strength, better performance, and long battery life.

Our gel models include a number of innovative features that provide a competitive advantage over other batteries. The gel electrolyte formula ensures consistent efficiency and significantly extends the life of the product. Lead-alloy meshes provide longer life and greater resistance to corrosion, as well as more centralized power to the terminals. Double insulation in spacer seals ensures maximum load flow between the plates, resulting in optimum performance.

Sealed batteries are of high quality because they minimize hydrogen loss and help regulate the internal pressure, thereby improving safety and productivity.

 

Advantages:

  • Maintenance-free
  • Optimum performance
  • Low temperature tolerant
  • Resistant to vibration and impact
  • Extremely low internal resistance at high discharge voltages
  • Greater load efficiency
  • High durability

When is it advisable to purchase a sealed maintenance-free battery?

The purchase of a sealed maintenance-free battery can be recommended in various situations and applications due to its advantages and particular characteristics. Some scenarios in which it is advisable to consider a sealed maintenance-free battery are:

  • - Occasional or infrequent use applications: If the battery is to be used in devices or equipment that are used infrequently, sealed maintenance-free batteries are ideal because they do not require regular servicing and maintenance, which facilitates their use in situations where constant monitoring is not possible or practical.
  • - Emergency back-up applications: Sealed maintenance-free batteries are excellent for emergency back-up systems, such as in uninterruptible power supply (UPS) systems, where the battery comes on line only when there is a power outage. Because they are sealed, they reduce the risk of leakage and do not require regular maintenance to maintain their performance.
  • - Confined or inaccessible spaces: If the battery will be installed in hard-to-reach locations or with limited space, a sealed maintenance-free battery is a more practical option, as it does not require topping up with water or checking electrolyte levels.
  • - Indoor applications: Sealed maintenance-free batteries are safe for indoor use as they are designed to prevent spillage of acid or other chemicals hazardous.
  • - Ease of use: These batteries are convenient and easy to handle, as they do not require water topping up or constant checking of electrolyte levels.
  • - Household and residential equipment: In applications such as residential solar power systems or back-up systems for computers and appliances, sealed maintenance-free batteries may be a suitable option due to their easy-to-use and low-maintenance nature.

However, it is important to note that sealed maintenance-free batteries also have some limitations. For example, their lifespan tends to be shorter compared to certain types of maintenance-free batteries, and they can be more expensive in certain cases. In addition, if they are subjected to heavy use or charge and discharge limits are exceeded, they may deteriorate more rapidly.

Ultimately, the choice of a sealed maintenance-free battery will depend on the specific needs and characteristics of the application in which it is to be used. It is always advisable to consult an expert or battery supplier for advice tailored to your specific requirements and conditions.

How long does a maintenance-free battery last?

Maintenance-free batteries, such as AGM (Absorbent Glass Mat) or gel batteries, are designed to minimise the need for user maintenance. Unlike conventional lead-acid batteries, which may require periodic topping up with distilled water, maintenance-free batteries are sealed and designed to be watertight, which prevents electrolyte loss and does not require topping up during their lifetime.

As for the life of a maintenance-free battery, it may vary depending on the type of battery and the quality of the product. In general, AGM and gel batteries have an expected life of 3 to 10 years, depending on the manufacturer, type of construction and conditions of use. Some high-quality, well-maintained batteries can exceed 10 years of service life.

Remember that although these batteries are more convenient in terms of maintenance, it is important to follow the manufacturer's recommendations and care for them properly to get the best performance and longest life.

How are maintenance-free batteries charged?

Maintenance-free batteries, such as AGM (Absorbent Glass Mat) or gel batteries, are charged in a similar way to other rechargeable batteries. However, due to their particular characteristics, it is important to follow some specific guidelines to ensure proper charging and prolong their life. Here are some general steps for charging this type of battery:

  • - Select a suitable charger: It is essential to use a charger that is compatible with the type of battery you have. Make sure the charger's voltage and charging current match the battery's specifications.
  • - Correct connection: Connect the charger to the battery making sure that the positive (+) and negative (-) poles are correctly connected. Modern chargers often have reverse polarity protections, but it is better to prevent connection errors.
  • - Slow charging: It is preferable to use a charger that offers a slow, steady charge rather than a fast charge, especially if you don't need to charge the battery quickly. A slow charge helps prevent overheating and can be more beneficial to the battery's lifespan.
  • - Full charge: Allow the battery to fully charge before disconnecting it from the charger. Avoid disconnecting it before it is fully charged, as this may affect its energy storage capacity.
  • - Temperature control: If it is possible to, charge the battery in a moderate temperature environment. High temperatures can affect charging efficiency and may be detrimental to the battery.
  • - Use of solar charge controller (if applicable): If you are using batteries in a solar power system, it is important to use a solar charge regulator to prevent overcharging and deep discharging, which will protect the life of the battery.

Remember to follow the manufacturer's specific instructions for charging your battery maintenance-free, as some batteries may have special requirements. Also, avoid charging the battery in a poorly ventilated location and be aware of the safety recommendations provided by the charger manufacturer. By following these guidelines, you can ensure proper charging and prolong the life of your maintenance-free battery.
