Long LG40-12 · Wheelchair battery 12V 40Ah GEL

Mobility battery Long LG40-12 LG Series 40Ah 12V

Designed for power wheelchairs, mobility scooters and light electric vehicles, the Long LG40-12 from the LG Series range offers 40 Ah of deep-cycle capacity with GEL technology. It replaces the original battery without adaptation in power wheelchairs and mobility scooters with a 199 × 166 × 171 mm format: same 40 Ah capacity and the positive terminal on the right.

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

What the Long LG40-12 is for

The Long LG40-12 is designed for power wheelchairs, mobility scooters and light electric vehicles. Wheelchairs and scooters normally use two identical batteries in series: replace them together. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 13.30 kg.

The Long LG40-12: LG Series range and GEL technology

Within the Long catalogue, the LG Series series groups the references designed for this use. The LG40-12 is the 40 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.

Size, terminals and hold-down of the Long LG40-12

The Long LG40-12 is made in the 199 × 166 × 171 mm format and weighs 13.30 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.

Long: the maker behind the LG40-12

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.

How to make it last longer

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.
