Stationary battery Q-Battery 12LS-26 26Ah 12V
Designed for UPS, alarms, telecoms and emergency lighting, the Q-Battery 12LS-26 offers 26 Ah with AGM technology on permanent float charge. It replaces the original battery without adaptation in UPS, alarm and emergency systems with a 165 × 176 × 125 mm format: same 26 Ah capacity.
In short: the Q-battery 12LS-26 (26 Ah, 165 × 176 × 125 mm). Verified equivalent alternatives: Ritar RT12260 and Q-battery 12LS-24.
- AGM technology: absorbed electrolyte, no spills, can be mounted at an angle.
- Long float life under permanent charge.
- Sealed and gas-free: suitable for cabinets and offices.
- Maintenance-free for its whole service life.
What the Q-Battery 12LS-26 is for
The Q-Battery 12LS-26 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 8 kg, F13 (M5) terminals and G112076 hold-down.
Technology inside the Q-Battery 12LS-26
The 12LS-26 is one of the Q-Battery references for this type of use; it shares the same manufacturing and quality-control criteria as the rest of the brand's catalogue.
In an AGM battery the electrolyte is absorbed in glass-fibre separators: there is no free liquid, it cannot spill and it can be mounted at an angle. That construction lowers internal resistance, speeds up recharging and multiplies cycle life compared with a conventional battery.
Size, terminals and hold-down of the Q-Battery 12LS-26
The Q-Battery 12LS-26 is made in the 165 × 176 × 125 mm format and weighs 8 kg. It uses a G112076 hold-down and F13 (M5) terminals, the system that anchors and connects it in the vehicle. 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.
What Q-Battery does differently
The Q-Battery catalogue runs from small alarm batteries to large traction monoblocs, always with sealed, maintenance-free technology. We guarantee that every Q-Battery arrives new, charged and with the manufacturer's full warranty.
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.
Official warranty
The Q-Battery 12LS-26 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
Order before 6:00 pm with stock available and it leaves today: mainland Spain and Portugal receive it in 24-48 working hours, the islands and the rest of the EU in 3 to 5 days. You have 14 days to return it if it has not been installed, with free collection on the mainland, and shipment tracking by email.

Frequently asked questions
Is the Q-battery 12LS-26 an AGM battery and what are the benefits of AGM?
Yes. The 12LS-26 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 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 long does the Q-battery 12LS-26 battery last?
Expected lifespan of the Q-battery 12LS-26 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 165×176×125 mm — also written as 165x176x125 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 batteries are equivalent to the Q-battery 12LS-26?
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.
