Two options stand out in the world of automotive batteries: absorbed gas mat batteries and lead acid batteries. While both serve the same purpose of storing and delivering electrical energy and share the same chemistry, their construction, performance and applications differ. Understanding the distinctions between these types can help consumers make informed decisions.

What is a regular lead car battery?

Also called flooded batteries, regular lead acid car batteries are the most common in cars, trucks and vans. Divided into six separate cells with positive and negatively charged plates, a flooded battery contains a liquid electrolyte solution that each plate is submerged in to create a path for electricity to flow through. 

A lead acid battery relies on this solution of liquid electrolyte to operate. Without it, limited chemical reactions hamper the communication between the lead plates. This significantly reduces the battery's capacity and voltage output, making it unable to provide the necessary power to start the car or run the electrical system. Operating a flooded battery without enough electrolyte can also damage the internal components of the battery and might lead to corrosion. Flooded batteries also need to be stored in well-ventilated areas of the vehicle, since they release gases into the atmosphere. 

What is an AGM car battery? 

Designed to provide more amps even if the car engine is off, absorbed gas mat (AGM) batteries are becoming more common in the industry. Instead of holding freely flowing electrolytes, AGM car batteries have a glass mat separator between the lead plates. Designed to absorb and immobilize electrolytes, the glass mat prevents spillage even if the battery is cracked or damaged. This design also has pressure relief values to regulate internal pressure and to avoid gas buildup, making AGM batteries ideal for use in vehicles with batteries in the trunk or under seats. 

AGM batteries require less maintenance than flooded batteries and are generally considered maintenance-free. Because the electrolyte is enclosed in the glass mat, these batteries can be mounted in various orientations without risking electrolyte leakage.

The differences in power output of AGM vs. lead

A battery’s internal resistance can affect its performance. The internal resistance of an AGM battery can be as low as 2%. In comparison, a flooded battery can have an internal resistance of 10-15%. The lower internal resistance means an increased battery voltage output while helping AGM car batteries recharge faster. This is important in help the battery recover quickly from deep discharges commonly occurring in hot weather conditions or because of the abundant technology in newer cars. 

Speaking of hot weather, regular lead batteries work well in any climate. However, using an AGM battery is best for those living in climates consistently above 80 degrees Fahrenheit. Exposure to high temperatures can cause car batteries to have increased electrolyte evaporation, reducing the battery's performance and lifespan. In addition, heat causes corrosion buildup and sulfation (crystal accumulation) on the battery plates. Since AGM batteries have the plates encased, these effects of heat are minimized.

Which is more expensive, AGM or lead car batteries? 

Initially, an AGM battery will cost more than a regular lead acid battery. The cost can be significant, in fact, as much as 40 to 100% more than the cost of a regular lead battery. 

Flooded batteries can last three to five years with regular maintenance and proper care. This lifespan will vary based on factors such as temperature, battery quality and cycling frequency. If the battery isn't maintained or lives in harsher conditions, that lifespan can drop from one to two years.

Owners can expect an AGM car battery to typically last between three and five years with proper usage. With its sealed design, internal components are protected from contamination and electrolyte loss, which contributes to its longevity. In some cases, higher-quality AGM batteries may last up to 10 years, depending on the application and environmental conditions. Also, AGM batteries are maintenance-free and eliminate the need for regular electrolyte checks and refills that are commonly required for flooded batteries.

Lithium Vs. AGM Vs. Lead Acid Batteries

1/11/

The three battery options are lead acid, AGM, and Lithium. Lead acid is standard for our Push-Around Series and Pro Series scissor lifts, AGM is the standard for our Zero-Turn Series lifts, and Lithium is an upgrade option for both our Pro Series and Zero-Turn Series lifts. Each battery choice has its pros and cons which will impact the machine's cost and performance. Making an informed decision to choose the right battery can help you increase your ROI. 

Lead Acid Batteries

Lead acid batteries are the cheapest upfront option when considering what battery to choose for your Hy-Brid Lift. However, there are some unexpected costs down the road that make lead acid batteries cost more than intended. 

When using lead acid batteries, over the span of 10 years you will have to replace 14 lead acid batteries and check and top off the water level over 120 times. Say each replacement battery is $125, which is already $ in maintaining your scissor lift not even considering the price for a worker doing a water check. Compared to Lithium batteries, the cost of lead acid batteries will cost 4-6 times the cost of using a lithium battery over 10 years.

AGM Batteries

Absorbent glass mat (AGM) batteries are spill-proof sealed lead acid batteries that require some maintenance.  AGM batteries have thin fiberglass mats which are saturated in acid and soldered into place before being compressed between the lead plates, effectively holding the battery’s electrolyte in place. AGM is a better option than standard lead acid when considering which battery to choose for your new scissor lift.

AGM batteries are a safer option compared to lead acid batteries because there is no need to water an AGM battery so workers are no longer exposed to the acid from the battery. However, there is some gas that vents out from the battery. 

AGM has a slightly longer life expectancy along with more charge cycles. The charge time for AGM batteries is around the same as a lead acid battery.

Lithium Batteries

Lithium batteries are the best option for your scissor lifts to increase your return on investment. Lithium batteries cost the most upfront but are the longest-lasting, most efficient battery for your scissor lift. Additionally, safety is improved because there is no battery acid to worry about.

Lithium increases ROI because you do not need to replace or maintain the battery for over 10 years. Within that same timeframe, you would have replaced your lead acid batteries at least seven times.

No maintenance lithium batteries can be stored as long as you need without charging. When charging the battery, you don't have to worry about reducing the battery life from opportunity charging, and charge times are significantly shorter due to a simpler charge process. With lithium, run times are longer because you can use more of the available amp-hours without damaging the battery allowing you to spend less time worrying about your battery and more time on more important tasks.
