### What the Long LGK100-12N is for

With 100 Ah, the Long LGK100-12N 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 34 kg.

### Will it fit your current battery tray?

The Long LGK100-12N is made in the 338 × 170 × 217 mm format and weighs 34 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.

### The Long LGK100-12N: LG Series range and GEL technology

Within the Long catalogue, the **LG Series** series groups the references designed for this use. The LGK100-12N is the 100 Ah model of that family, with the same performance as its siblings in other sizes.
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.

### Long: the maker behind the LGK100-12N

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.

### Manufacturer's warranty

The Long LGK100-12N 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.

### 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.

### Delivery times and returns

Order **before 6:00 pm** with stock available and it leaves today: mainland Spain and Portugal receive it in 24-48 working hours, the islands and the rest of the EU in 3 to 5 days. You have **14 days** to return it if it has not been installed, with free collection on the mainland, and shipment tracking by email.

## Frequently asked questions

### Is the Long LGK100-12N a GEL battery? What is GEL used for?

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.

### What size is this battery?

Dimensions (length × width × height) are 338×170×217 mm — also written as 338x170x217 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.

### On which side is the positive of the LGK100-12N model?

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.
