This is a high-rate 12 V, 35 Ah AGM (VRLA) deep-cycle battery built on the Gruber Power Services 58EGPS-12-35-I(T6) platform. It is ideal for use in power wheelchairs, mobility scooters, and other medical mobility equipment where reliable runtime and fast discharge capability are critical.
Many 24 V power wheelchairs and scooters are built around two 12 V, 35 Ah batteries in series; some 36 V and 48 V mobility platforms use three or four of these blocks. This model is a direct-fit replacement for most U1-size AGM wheelchair batteries.
This page is for a single loose battery. Order two for a typical 24 V wheelchair pack (and more for 36 V or 48 V systems). If you need help confirming compatibility with your chair or scooter, contact our technical support team.
