In short: the Long LG45-12N (45 Ah, 199 × 166 × 171 mm, positive terminal on the right). Verified equivalent alternatives: Long LG50-12 and Long LG50-12N.

• 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 LG45-12N is for

With 45 Ah, the Long LG45-12N 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 15 kg.

The Long LG45-12N: LG Series range and GEL technology

The LG Series is the Long range the LG45-12N 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.

GEL technology fixes the acid in a solid gel. That removes maintenance and leaks and gives very long cycle life, in exchange for slightly slower recharging and lower peak current than an AGM.

Size, terminals and hold-down of the Long LG45-12N

In terms of format, the Long LG45-12N measures 199 × 166 × 171 mm (length × width × height) and weighs 15 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. 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 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.

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.

Official warranty

The Long LG45-12N 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.
