The Long WP4.5-12 in practice
WP4.5-12 vs Long WP5-12E
The Long WP4.5-12 offers 4 Ah and 0 A cold cranking in a 90 × 70 × 107 mm case. The Long WP5-12E, same brand and technology, goes up to 5 Ah and 0 A Going up is only worth it if the tray allows it and the car cranks lazily in the cold; in normal use this one is plenty.

Mobility battery Long WP4.5-12 WP Series 4.5Ah 12V
The Long WP4.5-12 with AGM technology delivers 4.5 Ah at 12 V with the cycle life that power wheelchairs, mobility scooters and light electric vehicles demand. It replaces the original battery without adaptation in power wheelchairs and mobility scooters with a 90 × 70 × 107 mm format: same 4.5 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 WP4.5-12 is for
With 4.5 Ah, the Long WP4.5-12 offers the daily range that power wheelchairs, mobility scooters and light electric vehicles need, with a sealed construction that is safe indoors. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 1.62 kg.
Will it fit your current battery tray?
It has external dimensions of 90 × 70 × 107 mm and weighs 1.62 kg. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery.
The Long WP4.5-12: WP Series range and AGM technology
The WP Series is the Long range the WP4.5-12 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.
AGM (Absorbent Glass Mat) technology seals the electrolyte in glass microfibre. The result is a maintenance-free battery that is highly vibration-resistant and able to withstand deep discharges that would ruin a classic lead-acid battery.
What Long does differently
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 WP4.5-12 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.
How to make it last longer
Use the original charger or one compatible with the battery technology (AGM/GEL) and always replace both batteries in the set together. Recharge the wheelchair or scooter after each use and do not leave it discharged for days: lead sulphates and loses capacity.
Shipping, delivery and returns
Order before 6:00 pm with stock available and it leaves today: mainland Spain and Portugal receive it in 24-48 working hours, the islands and the rest of the EU in 3 to 5 days. You have 14 days to return it if it has not been installed, with free collection on the mainland, and shipment tracking by email.

Frequently asked questions
Is this battery AGM? What is it for?
Yes. The WP4.5-12 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 dimensions of the Long WP4.5-12 battery?
Dimensions (length × width × height) are 90×70×107 mm — also written as 90x70x107 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.
