Long WP18-12 WP Series · Wheelchair battery 18Ah AGM

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

The Long WP18-12 with AGM technology delivers 18 Ah at 12 V with the cycle life that power wheelchairs, mobility scooters and light electric vehicles demand. Its 181 × 76 × 167 mm make it the exact replacement for the 18 Ah battery fitted as standard to many power wheelchairs and mobility scooters.

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

What the Long WP18-12 is for

The Long WP18-12 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.

Will it fit your current battery tray?

The Long WP18-12 is made in the 181 × 76 × 167 mm format 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 WP18-12: WP Series range and AGM technology

The WP Series is the Long range the WP18-12 belongs to: it shares the same construction and quality criteria with the rest of the series, and varies in capacity and format to suit each vehicle.

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.

Why choose Long batteries

Long (Kung Long Batteries) is one of the world's largest manufacturers of sealed VRLA batteries. Its AGM and GEL series for UPS, mobility, alarms and cycling are found in equipment worldwide as original equipment. All the Long batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty.

Warranty and coverage

The Long WP18-12 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.

Usage and maintenance tips

Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators. Use the original charger or one compatible with the battery technology (AGM/GEL) and always replace both batteries in the set together.
