The impact of battery type on scooter performance and usability

Sealed Lead-Acid (SLA) Batteries

Performance: SLA batteries last longer and are more durable than other batteries. They require regular maintenance and refilling of water. They should be checked for leaks. So if any of the above is not done, it could greatly degrade the performance and safety of the mobility scooter. 

Usability: SLA batteries are generally lighter than the other alternatives, which makes the scooter easier to handle. However, it would not suit those who do not like regular maintenance.

Gel Cell Batteries

Performance: Gel batteries for mobility scooters have a shorter lifespan when compared to SLA batteries, which might affect long-term performance. But they provide consistent power output, beneficial for reliable, everyday use.

Usability: The spill-proof design enhances safety, and is allowed onboard aeroplanes too, hence, making it an excellent choice for users who travel frequently by air.

AGM (Absorbent Glass Mat) Batteries

Performance: AGM mobility scooter batteries utilize the latest technology to offer excellent charge efficiencies, enhancing performance across conditions. Their shockproof and spill-proof characteristics ensure consistent power delivery during various operational stresses.

Usability: These batteries require minimal maintenance, are safe from spills and shocks, and are approved for air travel. Despite being expensive, their durability and ease of use provide optimum convenience and reliability for all users and meet different requirements.

Lithium Batteries 

Performance: Lithium Batteries for mobility scooters have a long life, and can last for upto 5-7 years with good care without needing replacement. It is lightweight. These batteries best suit lightweight collapsable mobility scooters.

Usability: Due to its lightweight aluminum battery pack and lithium 12V, this battery is perfect for frequent air flyers. The color also blends well into the wheelchair. The battery fully charges within 6 to 8 hours, hence keeping you on the move without wasting time in long charging hours. 

Choosing the Right Battery for your Mobility Scooter

  1. Frequency of use: If you plan to use your mobility scooter to travel long distances, choose a durable battery that can withstand more use without decreasing the performance.  
  2. Battery range on Single Charge: Your battery should not run out of charge now and then. So choose a battery that can hold a charge for longer periods, based on the distance you commute.
  3. Weight Bearing: First ensure the scooter you buy should be able to bear the weight of the rider. Then, choose a battery with the capacity to bear the weight of both; the rider and the weight of the scooter.
  4. Speed ​​requirements: Depending on your desired speed for comfortable and efficient travel, for example, if you use the scooter for sports or are a speed enthusiast, then go for a battery that can power your scooter to meet those requirements, without compromising the on the safety and performance.
  5. Terrain Availability: If you use your mobility scooter on rough terrains such as grass, or steep or sloping terrains, choose a battery with the capacity to handle such conditions while maintaining a comfortable and safe glide. 
  6. Safety: Safety should be the most important priority. Check for safety features such as spillproof, temperature-controllable batteries. The battery should meet international standards. Make sure the battery is not damaged before buying, and always get it checked before delivery. 

Tips to Extend Life of your Mobility Scooter Battery

Many factors influence battery life, including scooter type (for example, heavy vs. light), terrain (e.g., flat roads vs. hilly terrain), duration of use (e.g., short vs. long daily commutes), along with battery type (e.g., lead-acid vs. lithium-ion), and lifestyle (e.g., frequent vs. occasional, conditions).To maximise battery life:

  • Follow proper charging techniques
  • Avoid Overcharging
  • Turn off the scooter while charging
  • Use Authorized chargers
  • Regular cleaning, maintenance, and service checks of the vehicle and the battery.

Charging Your Mobility Scooter Battery

  • Determine when to charge the battery by checking on the battery indicator or based on the scooter usage. It is important to recharge before the battery level goes too low or switches off.
  • Ensure the scooter is switched off and then connect to the port. Use an authorized charger only. Charge only for the manufacturer’s recommended duration and do not overcharge. 
  • Do not leave the battery charging overnight or for long periods after full charge. Check the battery indicator signal to know if the battery is fully charged.

Common Symptoms of Mobility Scooter Battery Problems

  • The mobility scooter battery runs out of charge faster than usual.
  • The batteries do not recognize the charger when connected to a power port. There is no indication of charging.
  • The mobility scooter switches off randomly.
  • The mobility scooter is not able to hold charge for long periods.
  • It takes longer time than normal to charge the scooter battery.
  • There is a decrease in the performance of the mobility scooter like the speed and range. 

Conclusion

Choosing the best battery for your mobility scooter requires careful consideration of several factors including type, usage, terrain, and individual needs. By following the guidelines outlined—with a focus on battery life, charging, maintenance, and safety—you can ensure the best performance of your mobility scooter. Maintaining your scooter regularly and understanding the indications for replacing batteries can increase the reliability and longevity of your scooter. Always consult professionals at Gilani Engineering to obtain the best results and maintain safety standards. 

Frequently Asked Questions 

Which battery is best for a mobility scooter?

Lithium-ion batteries are considered the best option for mobility scooters due to their lighter design, longer life, faster charge, and higher energy density when compared to SLA batteries. 

What is the average battery life of a mobility scooter? 

The average life of a mobility scooter generally ranges from 1 to 3 years, and the lithium batteries last upto 5 to 8 years, depending on factors such as frequency, charging, terrain, and battery type. Lithium, AGM and Gel Cell batteries tend to last longer than SLA batteries.  

Are mobility scooter batteries rechargeable?

Yes, mobility scooter batteries can be recharged to restore functionality and extend life.

How do I know if my mobility scooter needs a new battery? 

Signs that you may need to replace your mobility scooter battery include reduced range per charge, slow acceleration, difficulty maintaining a charge, the need to charge frequently, and possible physical damage or swelling on the battery casing. 

Can I install a high Ah battery in my mobility scooter?

It is important to consult with the manufacturer or a qualified technician before replacing your mobility scooter battery with a higher Ah (amp-hour) rating. While a higher Ah battery can get you farther on any charge, it must match the scooter’s power requirements, charging system, and physical dimensions to ensure optimum performance and efficiency.

Can you overcharge a mobility scooter battery?

No, by doing so, the battery will get damaged in the long run. It will reduce the lifespan of the webiste and the overall performance of the mobility scooter.
