## Quick description

Long WP55-12: electric wheelchair battery with 12 V and 55 Ah, measuring 226 × 135 × 229 mm.

## Description

## Who the Long WP55-12 is for

The Long WP55-12 is a deep-cycle battery for electric wheelchairs: sealed, maintenance-free and built to discharge and recharge every day without losing capacity. It is fitted as a 12 V pair and takes hundreds of daily cycles, something a starter battery could not handle.
The WP55-12 belongs to the Long WP Series range. [See all Long batteries](https://bateriasonline.es/en/long-batteries)

## Inside the WP55-12: AGM technology

The WP55-12 is AGM: the electrolyte is absorbed in glass fibre mats, so it is sealed and spill-proof. Being sealed, the WP55-12 can be fitted in the boot or under a seat with no risk of spills.
