Mobility battery Long LGL150-12N LG Series 150Ah 12V

Designed for power wheelchairs, mobility scooters and light electric vehicles, the Long LGL150-12N from the LG Series range offers 150 Ah of deep-cycle capacity with GEL technology. Its 483 × 170 × 240 mm and the positive terminal on the left make it the exact replacement for the 150 Ah battery fitted as standard to many power wheelchairs and mobility scooters.

  • Sealed AGM/GEL: safe indoors and in transport.
  • GEL: excellent resistance to deep discharge and long cycle life.
  • Approved for air and sea transport (VRLA).
  • No maintenance, no water top-ups.

What the Long LGL150-12N is for

The Long LGL150-12N is the usual replacement in power wheelchairs, mobility scooters and light electric vehicles. Recharge after each use and avoid leaving it discharged for days. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 45.80 kg.

The Long LGL150-12N: LG Series range and GEL technology

Within the Long catalogue, the LG Series series groups the references designed for this use. The LGL150-12N is the 150 Ah model of that family, with the same performance as its siblings in other sizes.

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 LGL150-12N

The Long LGL150-12N is made in the 483 × 170 × 240 mm format and weighs 45.80 kg. The positive terminal on the left 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 LGL150-12N

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. All the Long batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty.

How to make it last longer

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

Official warranty

The Long LGL150-12N 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.

Delivery times and returns

Orders placed before 6:00 pm with the battery in stock ship the same day. Delivery in mainland Spain and Portugal takes 24-48 working hours; for the Balearic Islands and the rest of the European Union allow 3 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 LGL150-12N model a gel battery? Where is it used?

Yes, this model is a GEL battery: sealed lead-acid where the electrolyte is in gel form. It tolerates deep discharges very well and is ideal for cyclic use (solar, motorhomes, electric wheelchairs, motorcycles). Requires a GEL-specific smart charger — max charge voltage ~14.1 V (vs 14.4-14.7 V for AGM). Lifespan 6-10 years.

How is the Long LGL150-12N battery installed in the vehicle?

In most devices it fits in 15-30 minutes with a 10 mm wrench; if the battery is under the seat or in the boot the time can double. See the step-by-step guide on our blog. Quick summary: 1) switch off the engine and remove the key; 2) locate the original battery (engine bay, boot or under seat); 3) disconnect the negative (−) terminal first, then the positive (+); 4) loosen the hold-down clamp and remove the old battery; 5) fit the new one in the same orientation — with positive on the left match the polarity shown on the product sheet; 6) connect the positive (+) first, then the negative (−). On devices with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile.

How long does the Long LGL150-12N battery last?

Expected lifespan of the Long LGL150-12N is 6 to 10 years in cyclic use (marine, caravan, solar) with controlled discharges. In cold regions it drops slightly due to cold-start stress; in very hot regions it also drops because of electrolyte evaporation. To extend its life: avoid deep discharges (headlights on with engine off), have the alternator checked yearly, and keep the battery clean and properly secured.

What are the measurements of the LGL150-12N model?

Dimensions (length × width × height) are 483×170×240 mm — also written as 483x170x240 mm — following the European DIN standard. Always measure the space in your device before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals.

What polarity does the Long LGL150-12N battery have?

Polarity: positive on the left. To identify it, place the battery in front of you with the terminals facing you and check which side the positive (+, marked with a red ring) is on. Before buying, verify the polarity matches your current battery: switching polarity forces longer cables or system reconfiguration, with short-circuit risk.

What are the equivalents of the LGL150-12N model?

Directly interchangeable batteries (same dimensions, same polarity, same Ah and CCA) are the OEM equivalents from leading brands: Bosch, Tudor, Exide and, depending on the model, Banner or Yuasa. Exact equivalence depends on technology — an EFB cannot be replaced with a conventional battery in Start-Stop devices. See the "Equivalents" section to view recommended options at the same performance level.
