Mobility battery Long WP3-6 WP Series 3Ah 6V

0.67kgWeight

The 6 V, 3 Ah Long WP3-6 from the WP Series range with AGM technology is the standard replacement for power wheelchairs, mobility scooters and light electric vehicles. Its 134 × 34 × 65 mm make it the exact replacement for the 3 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 WP3-6 is for

With 3 Ah, the Long WP3-6 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 0.67 kg.

Will it fit your current battery tray?

In terms of format, the Long WP3-6 measures 134 × 34 × 65 mm (length × width × height) and weighs 0.67 kg. Before replacing it, measure your current battery tray: if all three dimensions and the terminal positions match, the swap is direct and needs no adapters.

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. We guarantee that every Long arrives new, charged and with the manufacturer's full warranty.

The Long WP3-6: WP Series range and AGM technology

The WP Series is the Long range the WP3-6 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.

Usage and maintenance tips

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.

Official warranty

The Long WP3-6 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.

When you get it and how to return it

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 WP3-6 model AGM? What does this technology offer?

Yes. The WP3-6 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 change this battery step by step?

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 WP3-6 battery last?

Expected lifespan of the Long WP3-6 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 dimensions of the Long WP3-6 battery?

Dimensions (length × width × height) are 134×34×65 mm — also written as 134x34x65 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 batteries are equivalent to the Long WP3-6?

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.
