Common UPS Battery Types on the Market: Lead-Acid vs. Lithium Batteries
Currently, the most common UPS batteries on the market fall into two main categories: lead-acid batteries and lithium batteries.
Lead-Acid Batteries – The Reliable Old Choice
Lead-acid batteries are a well-established and cost-effective option. They come in two types:
- Flooded (Open) Lead-Acid Batteries: These have a lower upfront cost and a decent lifespan, but they require regular maintenance, such as adding water or acid.
- Sealed (Maintenance-Free) Lead-Acid Batteries: These are more convenient since they don’t need electrolyte refilling.
However, lead-acid batteries have some drawbacks:
- They are bulky and heavy.
- Their cycle life is limited (typically around 500 charge-discharge cycles).
- They usually last 2-3 years before needing replacement.
Lithium Batteries – The Rising Star
Lithium batteries have gained popularity in recent years due to their superior advantages:
- Higher energy density – They store more power in a smaller, lighter package, allowing UPS systems to run longer.
- Longer lifespan – High-quality lithium batteries can endure thousands of charge cycles, lasting 7-8 years or more with proper use.
- Space-saving and lightweight – Ideal for compact installations.
