Lead Acid Batteries

Lead cell batteries are rechargeable high-power batteries with high current levels, ideal for various backup power supply storage and photovoltaic applications. These sealed batteries feature multiple cells and lead plates with reduced self-discharge power for extended periods. These batteries also recharge using suitable chargers with high-surge current yet low energy-to-weight and energy-to-volume ratios. With a typical 6 to 24V, they are available in various sizes and voltage specifications. Sealed batteries (SLAs) are the original flooded-style modification batteries preventing operators from cell compartment reach. 

Why Buy a Lead Cell Battery?

The cost-effective lead acid battery does not require high maintenance requirements with leak-proof features and extended life than common battery types. This rechargeable battery is ideal for highly demanding environment applications with less discharge power and low energy density. 

How Do These Batteries Work?

The lead acid battery works straightforwardly by making specific essential reactions. The oxygen within lead dioxide reacts with hydrogen ions to produce water, followed by lead reaction with sulphuric acid for lead sulphate formation. Finally, the ions moving via the electrolyte produce a considerable amount of current flow. 

Types of Lead Acid Batteries:

The two types of lead acid batteries include Gel and AGM Lead Acid Batteries:

  • Gel Batteries: Gel batteries feature a gel-like liquid formed when silica is used in batteries that turn the acid into a gel for leak-proof applications. These batteries offer slow discharge rates but slightly lower power capacity than similar AGM battery sizes. They operate in high temperatures with profound cycle ability and ensure proper battery recharging to avoid premature failures. 
  • AGM (Absorbed Glass Mat) Batteries: Batteries with AGM technology contain an electrolyte-wicking glass mat between the battery plates where enough liquid is stored to keep the glass mat wet for leak-proofing applications during battery damage or breaking. These batteries are best for high amps requirements with extended life spans when appropriately used (not discharged over 60%). 

Typical Lead Acid Battery Applications

Lead acid batteries offer versatile applications in a great range of systems and environments, such as:

  • Small Scale Power Storage Systems (UPS)
  • Automobiles
  • Power Systems (Large Scale)
  • Emergency Lights
  • Alarm Systems
  • Solar Panels
  • Communication Systems
  • Renewable Energy Systems
  • Large Electronic Toys
  • Stair Lifts.
