Lead acid batteries are an essential type of rechargeable battery, known for their reliability and ability to supply high surge currents despite a low energy-to-weight ratio and low energy-to-volume ratio. These characteristics make them ideal for applications requiring large power surges, such as backup power supply storage. Their robustness and long lifespan make sealed lead acid batteries particularly suitable for renewable energy systems, especially in photovoltaic (PV) applications where they capture and store surplus solar energy for later use. Lead acid batteries are available in a wide range of sizes and configurations to meet various needs, with typical voltages ranging from 12V to 24V.

One example of a high-quality lead acid battery is the [RS PRO 12V T1 Sealed Lead Acid Battery, 7Ah](https://au.rs-online.com/web/p/lead-acid-batteries/5375488), which features:

- Low gas emissions and over 99% recombination efficiency
- Excellent recovery from deep discharge
- Leak-proof, sealed battery design
- ABS resin case conforming to UL94-HB
- Compliance with road transport regulations (UN2800) for wet, non-spillable batteries
- Air transport compliance with IATA and ICAO special provision A67 for wet, non-spillable batteries

## **What are lead acid rechargeable batteries used for?**

Lead acid batteries are widely used in various power storage applications due to their ability to provide reliable and stable power. Some common uses include: 

- **Emergency Lighting:** Providing backup power for lighting systems in case of power outages.
- [**Uninterruptible Power Supplies (UPS**](https://au.rs-online.com/web/c/power-supplies-transformers/power-supplies/uninterruptible-power-supplies/)**):** Ensuring continuous power supply for critical systems like computers and medical equipment during power failures.
- **Alarm Systems:** Powering security systems to maintain their operation even during power interruptions.
- **Automobiles:** Serving as the primary power source for starting, lighting, and ignition systems in vehicles.
- **Industrial Applications:** Used when robust and reliable power sources are required. Common industrial use-cases of lead acid batteries include:
    - **Backup Power Systems:** Providing emergency power for critical systems in hospitals, data centres, and industrial plants.
    - **Renewable Energy Storage:** Storing energy from solar panels and wind turbines to provide power when renewable sources are not available.
    - **Industrial Equipment:** Powering machinery and equipment such as forklifts, floor scrubbers, and aerial work platforms.
    - **Telecommunications:** Ensuring uninterrupted power for communication infrastructure and equipment.
    - **Marine Applications:** Providing reliable power for boats and other marine vessels, ensuring operation of navigation systems, lights, and communication devices.

## **How do lead acid batteries work?**

Lead acid batteries operate through a chemical reaction between the lead dioxide (PbO2) on the positive plate and the sponge lead (Pb) on the negative plate, both submerged in a sulfuric acid (H2SO4) electrolyte. When the battery discharges, the lead dioxide reacts with hydrogen ions to form water, and the lead reacts with sulphate ions to form lead sulphate (PbSO4). During charging, this process is reversed, converting lead sulphate back into lead, lead dioxide, and sulfuric acid. The movement of ions through the electrolyte creates the electrical current that powers devices.

## **Gel Vs AGM Lead Acid Batteries**

### **AGM (Absorbed Glass Mat)**

AGM batteries use a special glass mat to wick the battery electrolytes between the plates. The glass mat holds just enough electrolyte to keep the mat saturated but contains no free liquid. This design makes AGM batteries spill-proof and allows them to deliver high currents on demand. AGM batteries are ideal for applications requiring a large number of amps and have excellent longevity if not discharged more than 60% between charges and fully recharged every 3-6 months.

### **Gel Batteries**

Gel batteries use silica to turn the electrolyte into a gel-like substance, which prevents leaks even if the battery casing is broken. While gel batteries offer slightly lower power capacity compared to AGM batteries of the same size, they excel in slow discharge rates and can operate at slightly higher temperatures. They are also known for their excellent deep cycle capability, although they require careful recharging to avoid premature failure.

## **What are sealed lead acid batteries?**

Sealed Lead Acid (SLA) batteries are an advancement over traditional flooded lead acid batteries. They are designed to be maintenance-free, leak-proof, and position-insensitive, making them more convenient and safer to use. SLAs prevent users from accessing the cell compartments, thus minimising the risk of acid spills and the need for regular electrolyte top-ups. The sealed design also ensures that the 12V or 24V battery can be used in any orientation without leaking.

## **Can sealed lead acid batteries be recharged?**

Yes, sealed lead acid batteries can be recharged using an appropriate [battery charger](https://au.rs-online.com/web/c/batteries-chargers/battery-chargers-power-banks/battery-chargers/). It is important to use a charger designed for SLA batteries to ensure safe and effective recharging. Overcharging or using an incorrect charger can damage the battery and shorten its lifespan. You can browse our selection of lead acid battery chargers to find the right match for your SLA battery.
