Long LG20-12N · Wheelchair battery 12V 20Ah GEL

Mobility battery Long LG20-12N LG Series 20Ah 12V

Designed for power wheelchairs, mobility scooters and light electric vehicles, the Long LG20-12N from the LG Series range offers 20 Ah of deep-cycle capacity with GEL technology. It replaces the original battery without adaptation in power wheelchairs and mobility scooters with a 181 × 76 × 167 mm format: same 20 Ah capacity and the positive terminal on the right.

• Thousands of useful cycles over its lifetime.
• Standard replacement format for wheelchairs and scooters.
• GEL technology: gelled electrolyte, fully sealed and maintenance-free.
• Designed to be discharged and recharged daily without losing capacity.

What the Long LG20-12N is for

With 20 Ah, the Long LG20-12N 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 6.70 kg.

The Long LG20-12N: LG Series range and GEL technology

Within the Long catalogue, the LG Series series groups the references designed for this use. The LG20-12N is the 20 Ah model of that family, with the same performance as its siblings in other sizes.

In a GEL battery the electrolyte is gelled with silica: it is fully sealed, cannot spill and tolerates deep discharge very well. It is the preferred technology in electric mobility, marine service and heavy-cycling applications.

Dimensions, polarity and mounting

The Long LG20-12N is made in the 181 × 76 × 167 mm format and weighs 6.70 kg. The positive terminal on the right decides which side the cables end up on: it is the detail that causes most buying mistakes, so check it before ordering. 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.

Why choose Long batteries

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.

Usage and maintenance tips

Recharge the wheelchair or scooter after each use and do not leave it discharged for days: lead sulphates and loses capacity. Use the original charger or one compatible with the battery technology (AGM/GEL) and always replace both batteries in the set together.

Manufacturer's warranty

The Long LG20-12N 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.
