Maximize battery life in UPS/Inverter by having ATC Feature

Maximize battery life in UPS/Inverter by having ATC Feature while charging the Tubular/SMF Lead Acid batteries is a very important feature.

ATC stands for Automatic Temperature Compensation. Generally, the specific gravity of liquids increases with decreasing temperature, which means as temperature decreases, the liquid contracts, making it denser. Similarly, the viscosity of a liquid also increases with decreasing temperature. So, the ATC feature helps solve this challenge in Lead Acid batteries by changing the boost or bulk voltage to change as per the temperature change in the ambient around the battery.

It is a feature that is found in Su-vastika Pure Sinewave UPS/inverter with ATC that allows the UPS to adjust its charging voltage based on the ambient temperature automatically. This helps to ensure that the battery is not overcharged or undercharged and prevents it from overheating, extending its lifespan to 1 year.,boost%20voltage%20of%2014.85V.

UPS/Inverter without ATC does not have this feature, so the charging voltage is fixed. This can lead to the battery being overcharged or undercharged, which can shorten its lifespan.

In addition to extending the battery lifespan, ATC can also improve the performance of the UPS. When adequately charged, the battery can provide more backup from UPS, leading to better overall performance.

Here is how ATC works in Su-vastika Pure Sinewave UPS with ATC:

  1. The UPS has a sensor that measures the ambient temperature.
  2. The UPS’s controller uses this temperature reading to calculate the correct charging voltage per ambient temperature.
  3. The UPS then adjusts its charging voltage accordingly.

    4. ATC monitors the battery’s temperature and adjusts the charging voltage accordingly. This helps prevent the battery from overheating, leading to premature degradation.

    Overall, UPS with ATC are a better choice than UPS without ATC. They extend the battery lifespan, improve the UPS’s performance, reduce electricity bills, reduce maintenance costs, and provide peace of mind knowing that the battery is appropriately charged.

    Types of Lead-acid batteries that the ATC will work with: –

    There are many types of lead-acid batteries, but they can be broadly categorised into four main types:

    • Flooded lead-acid batteries are the most common type of lead-acid battery. They are inexpensive and easy to maintain but require regular watering to prevent the electrolyte from drying out.
    • Gel-cell lead-acid batteries have a gel-like electrolyte that prevents the battery from spilling. They are more expensive than flooded lead-acid batteries but also more resistant to vibration and extreme temperatures.
    • Absorbed glass mat (AGM) lead-acid batteries use a fibreglass mat to absorb the electrolyte. This makes them more compact and lightweight than flooded lead-acid batteries and has a longer lifespan.
    • Tubular lead acid batteries: Tubular lead acid batteries have a different design than traditional lead acid batteries. The plates are made of thin tubes instead of flat plates. This makes them more resistant to sulfation, which can extend the battery life. Tubular lead acid batteries are more expensive than traditional lead acid batteries but can last longer and have a higher discharge rate.
      Here are some of the benefits of using a UPS with ATC:

      • Reduced electricity bills: ATC can help reduce your electricity bills by preventing overcharging. The battery will not waste energy by charging beyond its capacity.
      • Extended battery life: ATC can help extend your life by up to 30%. This is because ATC prevents the battery from overcharging, one of the leading causes of battery failure.
      • Reliable power backup: ATC can help ensure your power backup is reliable. This is because ATC prevents the battery from undercharging, which can lead to power outages.
      • Reduced maintenance costs: ATC can help to prevent the battery from overheating by monitoring the battery’s temperature and adjusting the charging voltage accordingly. This can lead to premature degradation and no need to water filling monthly.

      Here are some of the drawbacks of using a UPS without ATC:

      • Shorter battery life: Without ATC, the battery is more likely to be overcharged or undercharged, which can shorten its lifespan.
      • Worse performance: Without ATC, the UPS may not be able to supply as much power to the battery, which can lead to worse overall performance.
      • High maintenance costs: Without ATC, the UPS may be unable to prevent the battery from overheating due to the need to fill the battery with water every month.
      • Less peace of mind: Without ATC, you may be unsure if the battery is charged correctly, leading to less peace of mind.

      If you are considering purchasing a home UPS, I recommend choosing one that has ATC. It is a valuable feature that can extend the battery life, improve the performance of the UPS, and provide more backup, high UPS efficiency, low battery maintenance cost and reduce the electricity bill.

  1. […] More features: MPPT controllers often have more features than PWM controllers, such as temperature compensation, load control, and battery type selection. These features can make MPPT controllers more versatile and user-friendly.… […]

  2. […] What is Pure Sinewave Inverter/UPS with ATC? A pure sine wave inverter/UPS with ATC is an uninterruptible power supply (UPS) that produces a pure sine wave output. This contrasts modified sine wave inverters, which produce a square wave output. Pure sine wave output is more desirable for sensitive electronics like computers, TVs, and appliances. THE ATC feature is called Automatic Temperature Compensation, which is required by the lead Acid battery like Tubular, SMF or Lead acid batteries so that they are compensated for the temperature and give a proper backup time when the temperature is very low.… […]
