The Long LG50-12 in practice

LG50-12 vs Long LG40-12

The Long LG50-12 offers 50 Ah and 0 A cold cranking in a 199 × 166 × 171 mm case. The Long LG40-12, same brand and technology, stays at 40 Ah and 0 A and costs €7.10 less. If you hesitate between the two at a similar price, take this one: more capacity in the same size never hurts.

Designed for power wheelchairs, mobility scooters and light electric vehicles, the Long LG50-12 from the LG Series range offers 50 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 50 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 LG50-12 is for

The Long LG50-12 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 14.80 kg.

Will it fit your current battery tray?

The Long LG50-12 is made in the 199 × 166 × 171 mm format and weighs 14.80 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. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery.

What Long does differently

Long (Kung Long Batteries) is one of the world's largest manufacturers of sealed VRLA batteries. Its AGM and GEL series for UPS, mobility, alarms and cycling are found in equipment worldwide as original equipment. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty.

The Long LG50-12: LG Series range and GEL technology

The LG50-12 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.

A GEL battery is the choice when cycle resistance and safety matter most: no gases, no liquid and thousands of partial discharges in its lifetime.

How to make it last longer

GEL batteries need lower charging voltages: always use a charger with a GEL mode so as not to damage the electrolyte. 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 LG50-12 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.

When you get it and how to return it

Orders placed before 6:00 pm with the battery in stock ship the same day. Delivery in mainland Spain and Portugal takes 1 to 2 working days; for the Balearic Islands and the rest of the European Union allow 1 to 5 working days. You have 14 days to return an unused battery; in mainland Spain and Portugal collection is free. We email you the tracking number as soon as the parcel ships.

Frequently asked questions

Is the Long LG50-12 a GEL battery? What is GEL used for?

Yes: in the LG50-12 the electrolyte is gelled. It is a sealed lead-acid GEL battery. With very good deep-discharge tolerance, it is ideal for cyclic use: solar, motorhomes, electric wheelchairs and motorcycles. It needs a GEL-specific smart charger: its maximum charge voltage is lower than that of an AGM.

What are the dimensions of the Long LG50-12 battery?

Before buying, measure the space in your device: one extra millimetre can stop the hold-down clamp from closing. The Long LG50-12 takes up 199×166×171 mm (length, width and height, terminals included).

On which side is the positive of the LG50-12 model?

It has the positive on the right (polarity). If your current battery has its positive on the other side, this one is not suitable without longer cables or a reconfigured system (short-circuit risk). Put it in front of you, terminals towards you: the post with the red ring and the + sign is the positive.

Long LG50-12 or Long LG50-12N: which one to choose?

Same case and same technology as the LG50-12: an alternative by size, not an official equivalent. Compared with the LG50-12 it has the same Ah and cranking power. It costs 83,90 € less. If the polarity matches and your equipment had a similar capacity, it works as a replacement; if in doubt, ask us with your model.
