Why Refurbished Batteries Are a Smart Choice for Backup Power

May 24, 2023

Battery storage systems paired with solar can offset demand charges, saving businesses money in the long run. They can also provide backup power when needed.

A refurbished battery has a similar life span as a new one. They are cheaper than a new car battery and more environmentally friendly since they reduce the amount of batteries that end up in landfills.


What are refurbished batteries? Backup power solutions that utilize batteries can significantly benefit people who want to keep their home or business running during a grid outage without constantly refueling a conventional generator. Traditional generators run on diesel, natural gas, or liquid propane and require a constant fuel supply. By contrast, battery systems can be charged from the electric grid or rooftop solar panels. They can provide backup power for much longer than a typical generator.

Home battery backup power can also save you money on your utility bill, particularly if you have time-of-use (TOU) rates and solar. Batteries can shift electricity consumption from times of high demand to lower rates or even wholly decouple from the grid and avoid expensive TOU fees and penalties.

Home backup power systems batteries are available as open vented Lead-Acid (VRLA) batteries, Sealed Lead-Acid (SLA), lithium-ion, or flow batteries. Flow batteries, for example, use a process known as vanadium redox to create a chemical reaction that provides energy. Lithium-ion batteries, commonly used in laptops and smartphones, are less sensitive to heat generation, faster charging, and offer a longer service life than lead-acid or nickel-cadmium (NiCad) batteries.

Flow and Lithium-ion batteries are typically more expensive than VRLA or SLA options. Still, they can benefit households that need replacing old car batteries and commercial applications like UPS systems.


While second-hand batteries may seem like a cheap and easy way to shave some money off your car’s battery cost, they often have a shorter lifespan, can leak through the damaged casing (that you won’t see until it’s too late), and could even cause damage to your vehicle that would have been avoided with a new battery. A refurbished battery comes with the peace of mind of knowing it’s been tested and inspected by a qualified automotive technician, so you can rest assured that it can perform its duties well for many years.

In addition to offering excellent value for your money, refurbished batteries are also eco-friendly. This is because they give new life to batteries that would otherwise end up in a landfill, which can adversely affect the environment.


Purchasing a refurbished battery can save you up to 85 percent in cost over a new one and offers a warranty for added peace of mind. It gives a second life to batteries that would have otherwise ended up in the scrap yard and is an eco-friendly choice for the planet. Plus, a battery that has been expertly reconditioned will work just as efficiently as one that’s brand new.

Moreover, a refurbished battery will benefit you from a whole load test, which can reveal how well the unit performs. This is a much more accurate picture than simply measuring the voltage of the cell, which factors like temperature, age, and other variables could influence.

Back Market’s refurbished batteries also have impressive certification and quality control. They only sell high-quality batteries reconditioned and tested for the best quality. This ensures you’ll have an excellent experience with your new battery, and you can rest assured knowing it will perform well.

To claim a refurbished battery’s warranty, you only need to return it within the specified timeframe with proof of purchase. However, the warranty will be void if you damage the battery with an improper install or other actions that violate OPTIMA’s Battery Warranty Policy.

Environmentally Friendly

Refurbished batteries help the environment by reducing the number of new batteries that must be produced. This reduces the environmental impact of manufacturing and minimizes the waste created when a battery is thrown away after it has reached the end of its life.

Reconditioned batteries can be used as backup power for your solar energy system and help you stay green by reducing energy bills. Reconditioned batteries can have up to 85 percent of their original capacity and have a warranty. This means they can last you a long time and help you save money by keeping your solar panel system up and running for longer.

The battery backup you choose for your solar system can be made from various types. Lead-acid batteries are the cheapest and most common option but require frequent maintenance. Nickel-cadmium batteries are more expensive but last longer and don’t need maintenance. Lithium-ion batteries are the most expensive and have the most extended lifespan, but they require no maintenance.

Many refurbished batteries are manufactured using recycled materials. They are also designed to be easily recycled when they end their life. Some companies are implementing reverse logistics programs to track where retired batteries are located, making transporting them back to recycling facilities easier. These efforts also help decrease the cost of shipping batteries to recycling plants.
