Stationary battery Ritar HR12-104W HR 26Ah 12V

8.60kgWeight

The 12 V, 26 Ah Ritar HR12-104W stationary battery from the HR range with AGM technology is designed for UPS, alarms, telecoms and emergency lighting. Its 166 × 175 × 125 mm make it the exact replacement for the 26 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.

Dimensions, polarity and mounting

The Ritar HR12-104W is made in the 166 × 175 × 125 mm format and weighs 8.60 kg. It uses 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 the Ritar HR12-104W is for

The Ritar HR12-104W 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 8.60 kg and F13(M5) terminals.

The Ritar HR12-104W: HR range and AGM technology

The HR is the Ritar range the HR12-104W 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.

Ritar: the maker behind the HR12-104W

With more than twenty years making sealed lead batteries, Ritar offers general-purpose, long-life, high-rate and front-terminal ranges for every stationary application. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty.

Warranty and coverage

The Ritar HR12-104W 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.

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.

When you get it and how to return it

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.

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 this battery AGM? What is it for?

Yes. The HR12-104W from Ritar 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 fit the HR12-104W model in my device?

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.

What is the service life of the HR12-104W model?

Expected lifespan of the Ritar HR12-104W 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 HR12-104W model?

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.

Which batteries are equivalent to the Ritar HR12-104W?

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.
