Designed for UPS, alarms, telecoms and emergency lighting, the **Long HTP12100A** from the **HTP Series** range offers **100 Ah** with AGM technology on permanent float charge. Measuring 507 × 106 × 235 mm, it is the direct replacement for UPS, alarm and emergency systems fitted from the factory with a 100 Ah battery of this format.
- AGM: faster recharging and better cycle resistance than a conventional battery.
- Instant response to mains failures.
- Low self-discharge and high reliability.
- Standard format for UPS and emergency systems.

### What the Long HTP12100A is for

With 100 Ah, the Long HTP12100A gives your UPS or emergency system the autonomy it needs. Replace all the batteries in the set at once. 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?

In terms of format, the Long HTP12100A measures 507 × 106 × 235 mm (length × width × height) and weighs 34 kg. 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 HTP12100A: HTP Series range and AGM technology

Within the Long catalogue, the **HTP Series** series groups the references designed for this use. The HTP12100A is the 100 Ah model of that family, with the same performance as its siblings in other sizes.
AGM means the acid is held in a glass mat instead of floating free. That is why the battery can be installed in the cabin without gases, survives more cycles and recovers its charge quickly.

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

### Warranty and coverage

The Long HTP12100A 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

Replace all the batteries in the set at once and avoid environments continuously above 25 °C. Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators.

### When you get it and how to return it

Same-day dispatch from our warehouse for in-stock orders placed **before 6:00 pm**: 24-48 working hours in mainland Spain and Portugal, 3 to 5 days in the islands and the rest of Europe. Returns are accepted for **14 days** if the battery has not been used (free collection on the Iberian mainland). You will receive tracking by email.

## Frequently asked questions

### Is the HTP12100A model AGM? What does this technology offer?

Yes. The HTP12100A from Long uses AGM (Absorbent Glass Mat) technology: a sealed lead-acid battery where the electrolyte is absorbed in a glass-fibre mat. It withstands more charge/discharge cycles than a conventional one, handles heat better and is the required technology for devices with advanced Start-Stop and regenerative braking. Expected lifespan: 5-8 years under normal conditions.

### What are the dimensions of the Long HTP12100A battery?

Dimensions (length × width × height) are 507×106×235 mm — also written as 507x106x235 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.
