The Long WPL26-12B with AGM technology is a 26 Ah, 12 V backup battery for UPS, alarms, telecoms and emergency lighting. It measures 166 × 175 × 125 mm, the format sought by anyone replacing a 26 Ah battery in UPS, alarm and emergency systems.

  • Maintenance-free for its whole service life.
  • Sealed and gas-free: suitable for cabinets and offices.
  • Long float life under permanent charge.
  • AGM technology: absorbed electrolyte, no spills, can be mounted at an angle.

What the Long WPL26-12B is for

Designed for UPS, alarms, telecoms and emergency lighting, the Long WPL26-12B is sealed, gas-free and suitable for technical cabinets and offices. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 8 kg.

The Long WPL26-12B: WPL Series range and AGM technology

Within the Long catalogue, the WPL Series series groups the references designed for this use. The WPL26-12B is the 26 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.

Size, terminals and hold-down of the Long WPL26-12B

In terms of format, the Long WPL26-12B measures 166 × 175 × 125 mm (length × width × height) and weighs 8 kg. 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. We guarantee that every Long arrives new, charged and with the manufacturer's full warranty.

How to make it last longer

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

Manufacturer's warranty

The Long WPL26-12B 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.

Shipping, delivery and returns

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 Long WPL26-12B an AGM battery and what are the benefits of AGM?

Yes. The WPL26-12B 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.

How is the Long WPL26-12B 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 — 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 many years does this battery last?

Expected lifespan of the Long WPL26-12B is 5 to 8 years in mild-climate device use with Start-Stop. 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 size is this battery?

Dimensions (length × width × height) are 166×175×125 mm — also written as 166x175x125 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 are the equivalents of the WPL26-12B 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.
