Q-battery 12DC-150 12V 150Ah is a battery for auxiliary services in motorhomes, caravans and campers. Powers the fridge, interior lighting, water pump and sockets while parked, with no need for campsite mains. Withstands daily discharges throughout the season.

With 150 Ah with conventional lead-acid technology, the Q-Battery 12DC-150 from the Deep Cycle Battery range supports continuous duty cycles in forklifts, pallet trucks, stackers and aerial work platforms. Measuring 328 × 180 × 276 mm, it is the direct replacement for forklifts and pallet trucks fitted from the factory with a 150 Ah battery of this format.
The Q-Battery 12DC-150 is designed for forklifts, pallet trucks, stackers and aerial work platforms: continuous duty cycles and repeated deep discharges. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 37.50 kg and ET terminals.
In terms of format, the Q-Battery 12DC-150 measures 328 × 180 × 276 mm (length × width × height) and weighs 37.50 kg. It uses ET 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.
Within the Q-Battery catalogue, the Deep Cycle Battery series groups the references designed for this use. The 12DC-150 is the 150 Ah model of that family, with the same performance as its siblings in other sizes.
Conventional lead-acid is the benchmark against which other technologies are compared: good cranking current, great tolerance to alternator charging and the best price per amp-hour.
Q-Battery specialises in AGM and GEL VRLA batteries for UPS, telecoms, solar and deep cycling, with long-life and tubular-plate series for industrial use. All the Q-Battery batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty.
The Q-Battery 12DC-150 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.
Replace the complete set at once and watch the operating temperature in hot warehouses. Follow the manufacturer's charging regime and do not interrupt full charging cycles.
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.

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.
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.
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.
With insulated gloves, remove the negative (−) cable first. Some UPS have protection fuses — note their position before removing.
Repeat with the positive cable (red, marked +). Important: never let a terminal touch metal of the car while the other is still connected.
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.
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.
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.
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.
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.
Expected lifespan of the Q-battery 12DC-150 is 4 to 6 years in regular device use without 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.
Dimensions (length × width × height) are 328×180×276 mm — also written as 328x180x276 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.
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.
