There are two main types of batteries for mobility scooters and it is important to understand the differences between them.
AGM (Absorbed glass matting) batteries are extremely resistant to vibration, are totally sealed, non-spillable and maintenance-free. AGM offers better cycling performance, minimal gassing and acid leakage when compared with conventional lead-acid batteries. The end result of all of the features of AGM technology is superior life performance. Naturally, this is a lead acid battery but does not have free-flowing liquid acid. Instead, the battery is filled with a type of glass matting which is absorbed by the battery’s acid.
The energy density of LITHIUM-ION is typically ten times that of the standard AGM battery. This means there is a higher energy density potential. This equates to a longer life span and a lighter weight (approx. one-third the weight of a lead acid battery) for the same output of power. Like lead acid batteries, Lithium-ion batteries are also maintenance-free and rechargeable. By comparison to AGM batteries, Lithium-ion batteries have only been on the market for a relatively short period of time, however, they are changing and improving daily. Since they are still relatively new, there is still a lot of misconceptions about the uses and benefits of Lithium-ion batteries.
Lithium batteries discharge evenly over their cycle unlike lead acid, AGM or Gel mobility batteries. You will not only get at least 40% more range but your scooter or powerchair will not slow down and labour up hills anymore. The speed of your scooter or powerchair will not be altered by Lithium-ion batteries, it will just be more even and consistent.
Lithium batteries can be discharged up to 100% of their capacity and can therefore provide power for longer than AGM, Gel and Lead Crystal batteries. Lithium batteries are maintenance-free and leak-proof as they do not contain electrolytes and are suitable for intensive use.
Lithium batteries are the perfect green alternative to lead acid batteries. Not only does the long lifespan of lithium batteries generate less waste than lead acid batteries, which are frequently purchased and thrown away, but lithium battery parts are also recyclable.
Lithium batteries in comparison to AGM batteries are more expensive but if weight is a significant factor for you then these are definitely the better option as the weight of them is significantly less when lifting the battery box in and out of a car for example.
Main benefits of Lithium Batteries.
- Weight massively reduced in comparison to AGM batteries
- Increased distance on a single charge.
