Lithium-ion batteries are a newer form of battery storage, they can be discharged deeper and have generally longer lifespan compared to lead-acid batteries, of around 13-18 years.
- Higher energy density so it can store more power relative to its size
- Do not require as much maintenance as lead acid batteries
- 80% depth of discharge
- 95% battery efficiency
- Average warranty period Is 10 years.
They are commonly used in vehicles, lighting, UPS systems, and energy storage applications. It contains a mix of lead dioxide, sulphuric acid and water. It creates a chemical reaction that can store and output electricity.
- Known for their reliability
- Have a proven track record of several decades
- Relatively lower costs than other batteries
- May take up a lot of space and may emit hydrogen gas
- Have a depth of discharge of 15-30%
- 80-85% battery efficiency
- Generally have a lifespan of just under 5 years.
Gel Batteries are valve regulated lead-acid (VRLA) batteries that do not release gas. Gel batteries keep the electrolyte suspended in a gel rather than a fiberglass matt.
- They are sealed, maintenance-free
- 20-40% depth of charge
- 80% battery efficiency
- Have a lifespan of up to 12 years
- Viable option for the budget minded for their reliability and low cost
