Permobil M400 Corpus HD 3G powerchair battery replacement.
Pair of high quality rechargeable 73.6ah GEL batteries for the Permobil M400 Corpus HD 3G powerchair with quick delivery.
The Permobil M400 Corpus HD and 3G are powerchairs with a reputation for a comfortable ride, robust mid-wheel drive, and tailor-made seating. Designed to accommodate complex postural requirements and active use, the chairs provide indoor manoeuvrability and outdoor traction. This is a listing for a direct-fit compatible pair of 12V 73Ah rechargeable batteries, designed to take the place of the originals in your M400 model—without alteration. The connections and footprint are identical, making fitting straightforward. No expert is needed here—just remove the side covers, disconnect the old units, and pop in the new pair. With a little care, most users or carers can have the task completed in under an hour.

These units use GEL battery technology—sealed, maintenance-free, and very robust. The electrolyte is contained in a gel-like substance, which translates to no leaks, no topping up, and less risk of spillage during transit or when tipped. It also means a longer cycle life under deep discharges, typical with high-use wheelchairs. When the day eventually arrives to replace them again, these GEL batteries are recyclable under licensed lead-acid battery schemes, minimising landfill waste and closing the recycling loop.
To make them last, be sure to recharge them after every use, even a short outing. That practice keeps internal resistance low and stretches performance. When the chair won't be in use for a while, give a full charge every month—a minimum to combat self-discharging and long-term cell damage.
