Stationary battery Long TPK12125 TPK Series 125Ah 12V
The Long TPK12125 with AGM technology is a 125 Ah, 12 V backup battery for UPS, alarms, telecoms and emergency lighting. Its 550 × 110 × 288 mm make it the exact replacement for the 125 Ah battery fitted as standard to many UPS, alarm and emergency systems.
- Instant response to mains failures.
- AGM: faster recharging and better cycle resistance than a conventional battery.
- Standard format for UPS and emergency systems.
- Low self-discharge and high reliability.
What the Long TPK12125 is for
The Long TPK12125 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 39 kg.
Will it fit your current battery tray?
The Long TPK12125 is made in the 550 × 110 × 288 mm format and weighs 39 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 TPK12125
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.
The Long TPK12125: TPK Series range and AGM technology
Within the Long catalogue, the TPK Series series groups the references designed for this use. The TPK12125 is the 125 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.
How to make it last longer
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.
Manufacturer's warranty
The Long TPK12125 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 TPK12125 model AGM? What does this technology offer?
Yes. The TPK12125 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 TPK12125 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.
What is the service life of the TPK12125 model?
Expected lifespan of the Long TPK12125 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 measurements of the TPK12125 model?
Dimensions (length × width × height) are 550×110×288 mm — also written as 550x110x288 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 TPK12125 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.
