Battery life is a key issue for electric seat users. Failure to manage this power supply can lead to difficult or annoying situations, especially if you are far away from home.
The power seat battery must be a 24 volt "deep cycle" battery, which is discharged for a long time, rather than a battery (12 volts) used for short-term charging in the vehicle. Deep circulation devices are available in several sizes: for example, group 22, group 24, and group 27. The larger the group number, the larger the battery, and the greater the stored power.
There are three types of batteries:
Lead acid or "wet" batteries generate electricity when lead interacts with sulfuric acid. These batteries need to be filled with distilled water regularly, possibly once a month. The main advantage of wet batteries is their low cost. The main disadvantage is that they may require special handling, especially during flight.
The gel battery has no liquid overflow or topping up. They are more expensive than the wet battery version, but they last longer and are better suited for air travel.
Absorbent glass mat (AGM) batteries, like gel batteries, do not require maintenance and are suitable for flight. They are very rugged, have better charging performance, and have a service life twice that of standard lead-acid batteries. They are also the most expensive.
Wheelchair batteries are sometimes the same as those used in the rowing industry. If you buy batteries out of your own pocket, you may save money by buying ocean deep cycle batteries. Be sure to check the chair manufacturer's specifications.
