Electric scissor lifts rely on deep-cycle batteries to deliver reliable power for elevated work. The most common options are 6-volt flooded lead-acid batteries (often GC2 size) wired in series for 24V or 48V systems, maintenance-free AGM batteries, and the newer Lithium Iron Phosphate (LiFePO4) batteries that offer faster charging and longer life.
Choosing the right scissor lift batteries is critical for safety, uptime, and total cost of ownership. In this guide, we explore the three main battery types used in scissor lifts, their pros and cons, popular brands, and why many operators are upgrading to lithium technology.
1. Flooded Lead-Acid (Wet Cell) Batteries
Flooded lead-acid batteries remain the traditional standard in most electric scissor lifts. They typically come in 6-volt GC2 form factor and are connected in series (four for 24V, eight for 48V) to power the lift’s hydraulic and drive systems.
Advantages:
- Lowest upfront cost
- Proven reliability over decades of use
- Widely available replacement parts and service
- Good performance in moderate temperatures
Disadvantages:
- Require regular maintenance: checking and topping up electrolyte levels
- Risk of acid spills and hydrogen gas emission during charging
- Shorter lifespan (typically 300–500 cycles)
- Heavier weight reduces lift runtime
- Slower charging times (8–12 hours for full charge)
Flooded batteries work well for fleets with dedicated charging areas and maintenance staff, but they are less ideal for indoor use or rental operations where safety and cleanliness matter.
2. AGM (Absorbed Glass Mat) Batteries
AGM batteries are a sealed, valve-regulated version of lead-acid technology. They use glass mats to absorb the electrolyte, eliminating the need for water additions.
Advantages:
- Completely maintenance-free
- Spill-proof and safer for indoor environments
- Better resistance to vibration and shock
- Faster charging than flooded batteries
- Longer lifespan (500–800 cycles)
Disadvantages:
- Higher purchase price than flooded batteries
- Still heavier than lithium options
- Sensitive to high temperatures and overcharging
- Gradual capacity fade over time
AGM batteries are popular in rental fleets and indoor applications where low maintenance and safety are priorities. Many operators choose them as a direct drop-in replacement for flooded batteries without changing chargers.
3. Lithium Iron Phosphate (LiFePO4) Batteries
LiFePO4 (often called LFP) batteries represent the latest advancement in scissor lift power. Brands like hydrocell specialize in purpose-built lithium solutions for aerial work platforms.
Advantages:
- Exceptionally long lifespan (2,000–5,000+ cycles)
- Fast charging (2–4 hours for full charge)
- Opportunity charging supported—no need for full discharge
- Up to 60% lighter than lead-acid equivalents
- Consistent voltage throughout discharge for stable performance
- Built-in BMS (Battery Management System) for safety
- No maintenance and zero emissions
- Better cold and hot temperature performance
Disadvantages:
- Higher initial cost
- May require compatible charger upgrades
The upfront premium is quickly offset by longer life, reduced downtime, lower energy costs, and eliminated maintenance. Many fleets report payback periods of 2–3 years when switching to LiFePO4 scissor lift batteries.

Which Battery Type Is Right for Your Scissor Lift?
For budget-conscious operators with proper maintenance facilities, flooded lead-acid batteries remain viable. Rental companies and indoor users often prefer AGM for its maintenance-free operation. However, fleets aiming for maximum uptime, lower total cost, and greener operations increasingly choose LiFePO4.
As battery prices continue to decline and performance advantages become clearer, lithium is rapidly becoming the new standard in electric scissor lifts. Investing in high-quality scissor lift batteries from trusted brands like hydrocell ensures safer, more productive aerial work for years to come.
