Which type of wheelchair battery has a longer lifespan and is less expensive?

Wet-cell batteries are often considered to have a longer lifespan and can be less expensive compared to other types of wheelchair batteries. They typically use lead-acid technology, which is a well-established and cost-effective option for powering various devices, including electric wheelchairs.

One of the advantages of wet-cell batteries is that they are widely available and generally less costly due to the mature manufacturing processes associated with lead-acid technology. They tend to provide reliable power output as well, making them suitable for many users. While they may require specific maintenance, such as topping off electrolyte levels, their initial affordability and longer operational life can be a significant benefit for users who prioritize cost and longevity.

When comparing with other battery types, gel or sealed batteries offer advantages in terms of maintenance and safety but often come at a higher cost. Lithium-ion batteries, while known for their compact size and lighter weight, usually have a higher upfront cost as well. Nickel-metal hydride batteries also tend to be more expensive and less commonly used in wheelchair applications.

Therefore, wet-cell batteries stand out as a practical choice for those seeking a balance between lifespan and affordability in wheelchair battery options.
