## Description

## Mobility battery Long WP12-6S WP Series 12Ah 6V

6*V* Voltage
12*Ah* Capacity
1.84*kg* Weight

The **6 V**, **12 Ah** **Long WP12-6S** from the **WP Series** range with AGM technology is the standard replacement for power wheelchairs, mobility scooters and light electric vehicles. Its 151 × 50 × 99 mm make it the exact replacement for the 12 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 WP12-6S is for

The Long WP12-6S 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 1.84 kg.

### Dimensions, polarity and mounting

It has external dimensions of 151 × 50 × 99 mm and weighs 1.84 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.

### Long: the maker behind the WP12-6S

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. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty.

### The Long WP12-6S: WP Series range and AGM technology

The **WP Series** is the Long range the WP12-6S 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.

### 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.

### Warranty and coverage

The Long WP12-6S 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 [[ks:cutoff]]**: 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 **[[ks:return_days]] 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 Long WP12-6S an AGM battery and what are the benefits of AGM?

Yes. The WP12-6S 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 this page. 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.

### What is the service life of the WP12-6S model?

Expected lifespan of the Long WP12-6S 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 WP12-6S battery?

Dimensions (length × width × height) are 151×50×99 mm — also written as 151x50x99 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.

### What are the equivalents of the WP12-6S model?

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.
