  • 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 Q-Battery 12LSX-28 is for

Designed for UPS, alarms, telecoms and emergency lighting, the Q-Battery 12LSX-28 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 3.76 kg and F2 (6 35mm) terminals.

Size, terminals and hold-down of the Q-Battery 12LSX-28

It has external dimensions of 151 × 98 × 95 mm and weighs 3.76 kg. It uses F2 (6 35mm) terminals, the system that anchors and connects it in the vehicle. Before replacing it, measure your current battery tray: if all three dimensions and the terminal positions match, the swap is direct and needs no adapters.

What Q-Battery does differently

The Q-Battery catalogue runs from small alarm batteries to large traction monoblocs, always with sealed, maintenance-free technology. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty.

The Q-Battery 12LSX-28: AGM Long Life range and AGM technology

Within the Q-Battery catalogue, the AGM Long Life series groups the references designed for this use. The 12LSX-28 is the 12 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.

Usage and maintenance tips

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 Q-Battery 12LSX-28 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.

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.

How to change the battery

Guide to replace a cyclic battery (12V 4-30Ah) for UPS, mobility scooter, alarm or backup device. Estimated time 10-15 minutes. Important: discharge residual voltage before handling.

⏱ 10-15 min🛠 Tools: Screwdriver or small wrench (3-5 mm typical) · Protective gloves
  1. Step 1. Power off and unplug the device

    Unplug the device (UPS, scooter, alarm) and leave it off for at least 30 seconds to discharge residual capacitor voltage. Work on an insulating surface.

  2. Step 2. Locate the battery compartment

    Usually under the seat (mobility scooter/wheelchair), in the rear module of the UPS, or behind a side panel with screws. Check the device manual for unusual models.

  3. Step 3. Disconnect the negative (−) first

    With insulated gloves, remove the negative (−) cable first. Some UPS have protection fuses — note their position before removing.

  4. Step 4. Disconnect the positive (+) terminal

    Repeat with the positive cable (red, marked +). Important: never let a terminal touch metal of the car while the other is still connected.

  5. Step 5. Remove the old battery

    Typical weight 1-15 kg depending on capacity. Many cyclic batteries are AGM/GEL — keep them upright. Do NOT invert the battery: even sealed, residue may exist.

  6. Step 6. Fit the new battery

    Same orientation and type (AGM, GEL or flooded). Polarity must match the device, not a chassis (this is not a car). Make sure terminals do not touch metal parts of the compartment.

  7. Step 7. Connect the positive (+) first

    On cyclic devices the order is reversed compared to cars: positive (+) first, negative (−) afterwards. Tighten without forcing — the plastic terminal housing of cyclic batteries damages easily.

  8. Step 8. Initial charge before first use

    Cyclic batteries ship at 60-80%. Before first use, connect the device charger for 8-12 hours (or use an AGM/GEL smart charger if available). This avoids short cycles and extends lifespan.

Frequently asked questions

Is the Q-battery 12LSX-28 an AGM battery and what are the benefits of AGM?

Yes. The 12LSX-28 from Q-battery 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 Q-battery 12LSX-28 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 this page. 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 long does the Q-battery 12LSX-28 battery last?

Expected lifespan of the Q-battery 12LSX-28 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 Q-battery 12LSX-28 battery?

Dimensions (length × width × height) are 151×98×95 mm — also written as 151x98x95 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.
