Batteries are essential now times, we can see batteries now in Hand watch to Automobile like Tesla cars to Electric Generation Plant by Solar, Without Batteries We cannot get Backup if Grid Fails to give Supply During Night. Mostly 12V 100AH batteries are used in this type of system due to its compatibility.

12V 100AH Batteries are made up of 3.6V 10Amp 4 PCs connected in Series and 10 strings Connected in Parallel with a Battery management system and protective charging circuit. Sometimes If there is a problem with Battery the output Voltage goes up to 16.8V, So Our Load should be able to handle 16.8V. To Start Reaction Sulphuric acid is added So this battery is a Lead Acid Battery and should charge at 14.4V.

12V 100AH lithium battery pack

We can Replace lead-acid batteries are lithium Ferrous phosphate cells which also give 12V 5amp when connected 4 in series and 20 strings in parallel. Charging of these batteries should be done at 14.4V which is similar to lead-acid batteries. This battery should be charged with a protection circuit and a balance charging option with a Battery management system.

Li-ion battery pack

One more option available is the Nickel-metal Hybrid cell that consists of 1.2V connected 10 in series and 10 strings in Parallel. These batteries are used in solar lights, cameras, and many places.

1.2V Nickel-metal Hybrid cell

Each cell has its pros and cons, But the biggest reason is the weight of the battery. Lead Acid batteries are cheaper and generally used in Automobiles but the weight of a 12V 100AH battery is 30 kg for 12V 100AH. But luckily this battery comes assembled in an Automobile battery shop.

As compared to a lead-acid battery, Lithium batteries are better than lead-acid batteries. LiFePO4 cells offer a reasonable capacity/weight ratio. 100 AH cells are available by connecting 3 cells in series in one module and connecting a Battery management system designed for Lithium-ion batteries to see voltage and temperature of a single cell, maintain all in the same voltage level required safety, and increase the life span of the battery. The weight of Lithium-ion batteries is 15kg which is half of the lead-acid batteries. This battery weight can be down further. For Example, one cell of 3.6V connects 20 parallel circuits to make one block of 3.6V 100amp. Now like these 3 blocks are connected in series it will give code number as 3S20P. 4 blocks in series and 20 cells in parallel. This complete set would be 4.2 Kg. So, the weight of the battery with the Battery management system and casing would be 5 Kg. The voltage range of this battery will be 12.6V to 8.4V. 12.6V when fully charged and 8.4V when fully Discharged.

The Main Disadvantage of a Lithium-ion battery is its short life span (nearby 500 cycles) and changes to catch fire if the battery is overcharged or mechanically damaged. Therefore, a Battery management system and a Mechanically Strong and weatherproof casing are required for the battery pack. All this would be no use if we fail to put Proper Charge for each type of battery according to its characteristics. If above all the points are taken into consideration battery will work smoothly and efficiently in its life cycle.

12V 100AH battery for ups are Different compared to the same rating of battery used in Automobile. Technically both have different discharge characteristics. UPS battery will Discharge slowly and can bear heavy discharge current compared to normal Automobile batteries. We observe this characteristic by taking a maintenance-free lead-acid battery of Automobile vehicles and UPS batteries. Automobile battery has a life span of 4-5 years whereas, UPS battery has a life span of 3-5 years due to their low discharge rate.

12V 100AH batteries used for UPS are available in different sizes. For Example, one battery has a size of 331*173*213mm, and the other battery has a size of 407*174*209mm. Here the First one is compact with a little bit more depth whereas, another one is larger but the depth is 4mm less. This Battery comes in Glue sealing so there is no fear of leakage of acidic substance from the battery. It gives protection from the explosion and the plates inside it are flat.

VRLA batteries are now widely used in UPS as it is maintenance-free therefore no headache to fill water due to their plate-like structure and no emission of flume and gases.

Tabular batteries consist of advanced technology by which active material is summarized in polyester tubes to prevent shedding. so, this type of battery is used where environmental conditions are rigid and a high rate of temperature change occurs in the atmosphere regularly.

Structural details of the 12V 100AH Batteries for UPS compare to normal batteries.

  • Outer encloser of batteries made up of UL9HB and LU 94V-0 ABS Plastic.
  • Negative terminal made of special PbCa alloy grids to optimize efficiency and gassing.
  • Positive terminal made up of PbCa grids that lower the rate of corrosion and expand life compared to a normal battery.
  • Internal resistance is 4.5m ohm at standard condition.
  • Terminal posts are of copper for High conductivity and sustain high current rapidly.

This type of battery is used in various places like UPS, Solar systems, Control systems, Power systems, Windfarms, Telecommunication systems.

Characteristics of 12V 100AH UPS Batteries.

  • Safe to use as it sealed
  • Good discharging rate
  • Good resistance to overcharge, discharge, high current.
  • Deep cycle application
  • Eco-friendly

Usage of batteries now rapidly increasing due to the increasing number of people moving to renewable sources of energy, Using Electric vehicles, going for solar street lights instead of Normal Street lights that consume power and depended on greed supply, increasing backups as there is tremendous growth in IT sector so servers should get continues power, mobile phones and much more.

Batteries vary from country to country, it depends on many factors such as transportation, national economies. 12V 100AH price in Sri Lanka ranges between 30000 to 50000 Sri Lankan Rupee for Branded Companies like Exide, Amron. If you find lower brands you may get in cheaper rates. This price mainly depends on the type, Brand, Type of batteries, place, and transport charges also added. Hope this information would be fruitful in adding knowledge about Rechargeable Dc batteries.
