  4. Absorbent Glass Mat (AGM) Batteries
  5. Battery Capacity
  6. Charge Time
  7. Cycle Life

Lead-Acid Batteries are a traditional choice for mobility scooters due to their affordability and reliability. These batteries come in two main types: sealed lead-acid (SLA) and flooded lead-acid. The SLA batteries provide safety by preventing leakage, whereas flooded batteries may require regular maintenance. According to a review by BatteryStuff.com in 2020, lead-acid batteries typically last for 1-2 years, depending on usage.

Lithium-Ion Batteries are becoming increasingly popular due to their lightweight and efficient energy storage. They have a longer lifespan compared to lead-acid batteries, often exceeding 5 years. Studies indicate that lithium-ion batteries charge faster and offer higher discharge rates. A 2021 article published by Electric Scooter Guide noted that many modern scooters now come equipped with lithium-ion options for improved performance.

Gel Cell Batteries are a variant of lead-acid batteries. They contain a gel electrolyte that reduces the risk of leaking. Gel batteries are suitable for extensive use and are often recommended for mobility scooters used in rough terrain. According to the Battery University guide, gel batteries generally last 3-5 years under optimal conditions.

Absorbent Glass Mat (AGM) Batteries are another type of sealed lead-acid battery. They utilize a fiberglass mat to absorb electrolyte, making them spill-proof. AGM batteries have lower internal resistance, resulting in better efficiency and quicker recharge times. A report by the Electric Power Research Institute (EPRI) highlights that AGM batteries are recognized for their durability and long cycle life.

Battery Capacity is critical for determining how long a mobility scooter can run on a single charge. Most batteries are rated in amp-hours (Ah). Higher capacity batteries will provide longer runtimes, crucial for users needing extended mobility support.

Charge Time varies between battery types. Lead-acid batteries typically take 8-14 hours to charge, while lithium-ion batteries can charge fully in 4-6 hours. Understanding these differences can help users plan their charging schedules effectively.

Cycle Life describes how many charge and discharge cycles a battery can withstand before its performance deteriorates. Lithium-ion batteries generally have a cycle life of about 500-1,500 cycles, while lead-acid batteries are typically rated for 200-500 cycles. Greater cycle life translates to less frequent battery replacements and lower long-term maintenance costs, making lithium-ion batteries economical in the long run.
