Long WP18-12U · Wheelchair battery 12V 18Ah AGM

Mobility battery Long WP18-12U WP Series 18Ah 12V

The Long WP18-12U with AGM technology delivers 18 Ah at 12 V with the cycle life that power wheelchairs, mobility scooters and light electric vehicles demand. Measuring 181 × 76 × 167 mm, it is the direct replacement for power wheelchairs and mobility scooters fitted from the factory with a 18 Ah battery of this format.

• AGM: faster recharging and better cycle resistance than a conventional battery.
• Sealed AGM/GEL: safe indoors and in transport.
• No maintenance, no water top-ups.
• Approved for air and sea transport (VRLA).

What the Long WP18-12U is for

The Long WP18-12U is designed for power wheelchairs, mobility scooters and light electric vehicles. Wheelchairs and scooters normally use two identical batteries in series: replace them together. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 6.30 kg.

Size, terminals and hold-down of the Long WP18-12U

It has external dimensions of 181 × 76 × 167 mm and weighs 6.30 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.

The Long WP18-12U: WP Series range and AGM technology

Within the Long catalogue, the WP Series series groups the references designed for this use. The WP18-12U is the 18 Ah model of that family, with the same performance as its siblings in other sizes.

AGM means the acid is held in a glass mat instead of floating free. That is why the battery can be installed in the cabin without gases, survives more cycles and recovers its charge quickly.

Why choose Long batteries

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. All the Long batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty.

Official warranty

The Long WP18-12U 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.

Usage and maintenance tips

Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators. Recharge the wheelchair or scooter after each use and do not leave it discharged for days: lead sulphates and loses capacity.
