When it comes to back-up power supplies, there are two main types of battery systems used: lead-acid batteries and lithium batteries. Each type of battery has its advantages and disadvantages, but the right choice for your back-up power supply depends on your needs.
Lead-Acid Batteries: The most common type of battery in back-up power supplies. They are relatively inexpensive and have a decently long lifespan.
- Advantages: More cost-effective in the short-term for back-up power. Lead-acid batteries are also relatively easy to maintain and can be recharged with a standard AC power source, making them a popular choice for industrial applications.
 - Disadvantages: Lead-acid batteries are heavy, can be difficult to transport, require periodic maintenance, and can be hazardous to handle.
 
Lithium-Iron Batteries: Becoming increasingly popular in back-up power supplies due to their high energy density and low weight. They are also quite efficient and have a long service life.
- Advantages: Lithium batteries are lightweight and have a high energy density, making them ideal for applications requiring portability. Additionally, they are more efficient than lead-acid batteries and require no maintenance. Less expensive in the long term.
 - Disadvantages: More expensive in the short-term, and some manufacturers (not Minuteman) design products without a battery replacement option due to the 10+ year lifespan.
