Stationary battery Long WPL150-12N WPL Series 150Ah 12V
The Long WPL150-12N with AGM technology is a 150 Ah, 12 V backup battery for UPS, alarms, telecoms and emergency lighting. It replaces the original battery without adaptation in UPS, alarm and emergency systems with a 483 × 170 × 240 mm format: same 150 Ah capacity.
- Sealed and gas-free: suitable for cabinets and offices.
- Maintenance-free for its whole service life.
- AGM technology: absorbed electrolyte, no spills, can be mounted at an angle.
- Long float life under permanent charge.
What the Long WPL150-12N is for
The Long WPL150-12N is designed for UPS, alarms, telecoms and emergency lighting: it sits on float charge and responds instantly to a mains failure. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 45.50 kg.
The Long WPL150-12N: WPL Series range and AGM technology
The WPL Series is the Long range the WPL150-12N belongs to: it shares the same construction and quality criteria with the rest of the series, and varies in capacity and format to suit each vehicle.
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 WPL150-12N
In terms of format, the Long WPL150-12N measures 483 × 170 × 240 mm (length × width × height) and weighs 45.50 kg. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery.
Long: the maker behind the WPL150-12N
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. We guarantee that every Long arrives new, charged and with the manufacturer's full warranty.
How to make it last longer
Replace all the batteries in the set at once and avoid environments continuously above 25 °C. Check the float voltage of the UPS or charger: a voltage that is too high shortens the life of a sealed battery.
Warranty and coverage
The Long WPL150-12N 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 this battery AGM? What is it for?
Yes. The WPL150-12N 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 do I change this battery step by step?
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 WPL150-12N 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 are the dimensions of the Long WPL150-12N battery?
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.
Which interchangeable batteries are there for this one?
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.
