The initial cost required to buy or install any inverter battery is quite high as compared to other batteries. Thus, you require a good amount of funds for this investment. But it is cost-effective in the long run, eliminating the cost of replacement and maintenance

Water cannot be replaced

Another disadvantage of the lithium inverter batteries is that water cannot be replaced if the batteries are continuously charged.

Voltage regulated chargers

While using a lithium inverter battery, you have to use a voltage-regulated lithium battery charger only for its working. No other types of chargers can be used.

Charge voltage

The charge voltage of lithium inverter batteries must be limited to extend its life. Eg. the charge voltage of about 13.5 to 13.8 volts must be used at a temperature of about 68°F.

5.What is the difference between UPS and inverter battery?

The device that changes direct current into alternating current is called inverter. The power supply is direct current. It is generally used in ac appliances that cannot be cut off. The UPS changes the alternating current into direct current. When the dc device that cannot be powered off is powered off, the UPS releases the backup power from the battery to supply the DC device. If it is alternating current electrical equipment, such as computer host, it is necessary to change the direct current into alternating current through the inverter to power the electrical equipment. In addition, the UPS battery pack comes with its own battery management function. For example, The BMS intelligent battery management function can extend the battery life by 30%, monitor the charging process of the used battery, adjust the floating charging voltage automatically as a function of the ambient temperature, and periodically test and check the battery, and warn the user if the battery is faulty.

6.Which is the best battery for inverter?

Many batteries can be used for an inverter. However, one such battery exceeds the rest and that is inverter lithium battery. This battery has a very modern and technologically advanced design. It shows great performance over a wide range of -20-60℃. Apart from this, it is also very durable and quite lightweight as well. It has a low-self discharge and can provide high currents to run high-power consuming devices such as freezers, microwave ovens, etc. This battery is also spill-free due to its valve-regulated engineering. It is also very responsive to load and is maintenance-free compared to other batteries. Therefore, the inverter lithium battery is one of the best batteries you could use for an inverter. It is important to note that the lithium ion battery pack voltage must be consistent with the inverter's nominal direct current input voltage.

7.What is the price for inverter battery?

The price of an inverter battery varies from one type to another. It depends upon the kind of inverter batteries which is present, the kind of brand as well as the type and quality of material which is being used. However, the key factor in determining the price of an inverter battery is the amount of power it supplies. A battery with a larger power will be more expensive compared to one which has a lower power. Eg. the price for an inverter having a battery of about 5000-10000W will have a price of around US$790-US$840/-. On the other hand, an inverter having a battery of 12V and 100Ah will cost you anywhere from around US$88-US$93.

8.Inverter battery application scenarios

The inverter battery has many different uses. Its main aim is to provide power to convert DC power to AC power. Due to this reason, it is used in several ways.

① Solar panel

Inverter batteries can be used with solar panels quite easily. With the help of a solar conversion kit, any battery can be transformed into a solar inverter. The solar conversion kit is kind of like a solar panel itself which when connected to any home inverter, can convert the entire mechanism into a hybrid form.

② 12-Volts sourced devices

Inverter batteries can also be used with many 12-Volt sourced devices to power them. Such devices include keyboards for computers, megaphones; especially the large, commercially used megaphones as well as radio boomboxes, etc.

9.how do I choose a good inverter battery?

There are a few things you should keep in mind before choosing an inverter battery.

① Power requirements

Before buying an inverter battery, find out about the devices you want to function in case of power failure. These devices can include fans, lights, television, refrigerator, etc. Every device requires a different power, thus, you need to make sure that the battery you choose can support all the devices you want to run at the same time.

② VA rating

Next, find out about the Volt Ampere Rating. Most inverters have an efficiency of about 60-80%. You need to choose the inverter with a VA Rating that matches your usage requirements.

③ Battery requirements of inverter

Last but not the least, find out what kind of battery your inverter needs. You need to find out about the capacity requirements for your inverter which needs to support and provide a backup power supply to the devices you want during power failure. According to that, you can deduce the inverter batteries that would meet your capacity requirements. Generally speaking, inverter lithium batteries can meet the needs of almost all application scenarios.

10.How do I know what size inverter battery I need? What battery capacity do I need for a 2000 watt power inverter?

The size of the inverter batteries that you need all depends upon the power (Watt or Ampere) consumption of the particular devices that you want to run. Devices that have a higher power rating will require a larger inverter battery. It is also recommended to buy a larger battery than you think you might need to prevent any power cuts etc. The battery capacity can be expressed in two ways: WH and Ah. Where: 1WH= lithium battery voltage V x ampere hour capacity (Ah). Kilowatt-hour (kWH) is a unit of energy but is usually used for electricity to measure how much energy is consumed by electrical equipment.

It is defined as the energy consumed by a 1000 watt appliance for one hour of continuous operation, also known as 1 kilowatt electricity. Watt is a unit of power, it’s the amount of energy (or work) consumed or produced per unit of time. It's defined as 1 joule per second (1 J/s) or 1 volt ampere (1 VA). The joule is also a unit of work and energy and is equivalent to the kilowatt-hour:1 KWH =1000 watts x 1 hour. For a 2000 Watt power inverter, it is recommended to get a 100Ah, 24 Volts battery to maximize its power requirements.

11.How long does an inverter battery last? What is the average life of inverter battery?

Different types of batteries can last for a longer or shorter duration of time as well. For example, when it comes to Lead-acid batteries, can only cycle about 300 times. Maintenance-free lithium iron phosphate batteries have a lifespan of about10 years with 80%DOD if charged and discharged on average once a day(4000/365≈10.96 ) while tubular batteries have the largest life span of about 6 plus years. The life an inverter batteries depends upon the category, quality, and condition of maintenance of the batteries. It is recommended to replace the inverter battery after a particular mentioned time or if you think the battery has worn out quite a bit.

12.What can damage inverter battery?

Inverter battery is sensitive and therefore, many things can damage it.

① Lack of regular maintenance

Lack of regular maintenance can cause harm and damage to your inverter batteries. Therefore, you need to regularly maintain your batteries by checking for any damage, topping it up with water, keeping them away from heat and water, etc. But there are exceptions, inverter lithium batteries are maintenance-free.

② Corrosion at grid

This corrosion occurs because the lead gets soft and falls off from the grid due to the chemical-reaction between the plates and sulfuric acid.

③ Corrosion at terminals

After constant use of the battery, corrosion at the terminals is inevitable. This affects the working of the inverter. Therefore, make sure to regularly clean the rusting and corrosion to keep the battery healthy.

④ Loose connections

Loose connections can damage the inverter batteries as well. This could lead to sparks and further damage. Always ensure that all the connections are tight and fully secured.

⑤ Over discharging

Inverter batteries are designed for deep discharging, however, you must ensure that frequent deep-discharging does not occur. This is because if the damage occurs, it is mostly irreversible when the battery is overly deeply discharged. However, lithium batteries are maintenance-free, so don't worry about the first two.

13.How do I keep my inverter battery healthy?

To keep your inverter battery healthy and increase its lifespan, care must be taken.

① Check battery only when fully charged

Ensure to check our battery for maintenance work only when it has had a full charge for about 10-15 hours.

② Check acid level

The acid levels in all the cells must be full and equal.

③ Clean battery terminals

Make sure to clean any rust or corrosion to keep the battery terminals clean.

④ Keep battery surface clean

To increase the life of your battery, regularly clean it with a dry cloth to remove any dirt or debris.

⑤ Check for damaged wires

Always check for broken, damaged, or melted insulated wires and replace such immediately to prevent any further damage to your inverter batteries. The above are all maintenance methods for lead-acid battery, but lithium inverter batteries are maintenance-free, so don't worry about these problems.
