Mobility battery Long WP20-12N WP Series 20Ah 12V
The Long WP20-12N with AGM technology delivers 20 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 20 Ah battery fitted as standard to many power wheelchairs and mobility scooters.
- Approved for air and sea transport (VRLA).
- No maintenance, no water top-ups.
- Sealed AGM/GEL: safe indoors and in transport.
- AGM: faster recharging and better cycle resistance than a conventional battery.
Will it fit your current battery tray?
It has external dimensions of 181 × 76 × 167 mm and weighs 5.95 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 the Long WP20-12N is for
The Long WP20-12N 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 5.95 kg.
The Long WP20-12N: WP Series range and AGM technology
The WP20-12N 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.
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.
Warranty and coverage
The Long WP20-12N 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.
Shipping, delivery and returns
Same-day dispatch from our warehouse for in-stock orders placed before 6:00 pm: 24-48 working hours in mainland Spain and Portugal, 3 to 5 days in the islands and the rest of Europe. Returns are accepted for 14 days if the battery has not been used (free collection on the Iberian mainland). You will receive tracking by email.

Frequently asked questions
Is the WP20-12N model AGM? What does this technology offer?
Yes. The WP20-12N 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.
How do I fit the WP20-12N model in my device?
In most devices it fits in 15-30 minutes with a 10 mm wrench; if the battery is under the seat or in the boot the time can double. See the step-by-step guide on our blog. Quick summary: 1) switch off the engine and remove the key; 2) locate the original battery (engine bay, boot or under seat); 3) disconnect the negative (−) terminal first, then the positive (+); 4) loosen the hold-down clamp and remove the old battery; 5) fit the new one in the same orientation — match the polarity shown on the product sheet; 6) connect the positive (+) first, then the negative (−). On devices with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile.
How long does the Long WP20-12N battery last?
Expected lifespan of the Long WP20-12N is 5 to 8 years in mild-climate device use with Start-Stop. In cold regions it drops slightly due to cold-start stress; in very hot regions it also drops because of electrolyte evaporation. To extend its life: avoid deep discharges (headlights on with engine off), have the alternator checked yearly, and keep the battery clean and properly secured.
What are the measurements of the WP20-12N model?
Dimensions (length × width × height) are 181×76×167 mm — also written as 181x76x167 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.
Which interchangeable batteries are there for this one?
Directly interchangeable batteries (same dimensions, same polarity, same Ah and CCA) are the OEM equivalents from leading brands: Bosch, Tudor, Exide and, depending on the model, Banner or Yuasa. Exact equivalence depends on technology — an EFB cannot be replaced with a conventional battery in Start-Stop devices. See the "Equivalents" section to view recommended options at the same performance level.
