Your Battery Backups are Dead

As technology has advanced, so have batteries evolved — resulting in newer, modern options to provide you power. 

When it comes to choosing the right battery to maintain your systems, you’d be surprised to know that batteries have changed a lot.

Where once upon a time, options were mainly limited to lead-acid, you’ll be happy to know that is no longer the single choice. As technology has advanced, so have batteries evolved, and lithium batteries are a viable choice for system maintenance. 

What's the best battery to maintain your systems?

Learn the five key differences between lead-acid and lithium batteries to know you have the best battery powering your system. In our Lead-acid vs. Lithium, we'll cover critical differences like cycle life, cost, efficiency — and more. 

Cycle Life

Cycle life is very important to know for the life of a battery. This helps you to know how many cycles the battery is good for before it expires.


Understanding the cost differences between lead-acid and lithium batteries will ensure you're not throwing away money. 


Efficiency is a key factor for a battery. The higher the efficiency, the faster the battery charges. This is especially great when dealing with solar.
