The Long WP50-12 in practice
WP50-12 vs Long WP40-12N
The Long WP50-12 offers 50 Ah and 0 A cold cranking in a 199 × 166 × 171 mm case. The Long WP40-12N, same brand and technology, stays at 40 Ah and 0 A with 1 mm less length and costs €9.10 more. If your car originally had the smaller capacity, this one gives extra reserve in the same case.

Mobility battery Long WP50-12 WP Series 50Ah 12V

It replaces the original battery without adaptation in power wheelchairs and mobility scooters with a 199 × 166 × 171 mm format: same 50 Ah capacity.
- Thousands of useful cycles over its lifetime.
- Standard replacement format for wheelchairs and scooters.
- AGM technology: absorbed electrolyte, no spills, can be mounted at an angle.
- Designed to be discharged and recharged daily without losing capacity.
What the Long WP50-12 is for
The Long WP50-12 is the usual replacement in power wheelchairs, mobility scooters and light electric vehicles. Recharge after each use and avoid leaving it discharged for days. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 15.10 kg.
The Long WP50-12: WP Series range and AGM technology
The WP50-12 is part of the Long WP Series range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family.
In an AGM battery the electrolyte is absorbed in glass-fibre separators: there is no free liquid, it cannot spill and it can be mounted at an angle. That construction lowers internal resistance, speeds up recharging and multiplies cycle life compared with a conventional battery.
Will it fit your current battery tray?
The Long WP50-12 is made in the 199 × 166 × 171 mm format and weighs 15.10 kg. For a direct replacement, the current battery tray must accept these dimensions and the same terminal layout; otherwise adapters will be needed or the hold-down will change.
What Long does differently
Long batteries combine large-scale production with ISO quality standards and a batch-to-batch consistency that has made them the de-facto standard in backup systems and electric mobility. We guarantee that every Long arrives new, charged and with the manufacturer's full warranty.
Care and maintenance
Recharge the wheelchair or scooter after each use and do not leave it discharged for days: lead sulphates and loses capacity. Use the original charger or one compatible with the battery technology (AGM/GEL) and always replace both batteries in the set together.
Official warranty
The Long WP50-12 comes with the manufacturer's official warranty against manufacturing defects. If it fails through a defect within the warranty period, we replace it at no cost to you.

Frequently asked questions
Is the Long WP50-12 an AGM battery and what are the benefits of AGM?
Yes. The WP50-12 from Long uses AGM (Absorbent Glass Mat) technology: a sealed lead-acid battery where the electrolyte is absorbed in a glass-fibre mat. It withstands more charge/discharge cycles than a conventional one, handles heat better and is the required technology for devices with advanced Start-Stop and regenerative braking. Expected lifespan: 5-8 years under normal conditions.
What are the measurements of the WP50-12 model?
Dimensions (length × width × height) are 199×166×171 mm — also written as 199x166x171 mm — following the European DIN standard. Always measure the space in your device before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals.
