Size, terminals and hold-down of the Long LG17-12

The Long LG17-12 is made in the 181 × 76 × 167 mm format and weighs 6.30 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.

With 17 Ah, the Long LG17-12 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 6.30 kg.

The Long LG17-12: LG Series range and GEL technology

The LG17-12 is part of the Long LG Series range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family.

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.

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

Warranty and coverage

The Long LG17-12 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.

Care and maintenance

Use the original charger or one compatible with the battery technology (AGM/GEL) and always replace both batteries in the set together. GEL batteries need lower charging voltages: always use a charger with a GEL mode so as not to damage the electrolyte.
