Wheelchairs and scooters normally use two identical batteries in series: replace them together. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 48.60 kg, A-Pole terminals and B0 hold-down. ### The Q-Battery 12SEM-180: Semitraction Battery range and conventional lead-acid technology The **Semitraction Battery** is the Q-Battery range the 12SEM-180 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. In a conventional battery the electrolyte is liquid and the lead plates are immersed in it. It is a mature, economical and easily recycled technology, ideal for starting vehicles in normal use. ### Size, terminals and hold-down of the Q-Battery 12SEM-180 It has external dimensions of 513 × 224 × 225 mm and weighs 48.60 kg. The positive terminal on the left decides which side the cables end up on: it is the detail that causes most buying mistakes, so check it before ordering. It uses a B0 hold-down and A-Pole 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. ### Q-Battery: the maker behind the 12SEM-180 The Q-Battery catalogue runs from small alarm batteries to large traction monoblocs, always with sealed, maintenance-free technology. All the Q-Battery batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty. ### Care and maintenance On batteries with filler caps, check the electrolyte level and top up only with distilled water. Recharge the wheelchair or scooter after each use and do not leave it discharged for days: lead sulphates and loses capacity. ### Official warranty The Q-Battery 12SEM-180 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 Orders placed **before 6:00 pm** with the battery in stock ship the same day.

It measures 513×224×225 mm in length × width × height, with the terminals included in the height. Measure the battery tray before ordering: a one-millimetre difference is enough for the hold-down clamp not to close. ### What polarity does the Q-battery 12SEM-180 battery have? It has the positive on the left (polarity). If your current battery has its positive on the other side, this one is not suitable without longer cables or a reconfigured system (short-circuit risk). Put it in front of you, terminals towards you: the post with the red ring and the + sign is the positive. ### Q-battery BATTERY-12SEM-180 or Varta M12: which one to choose? It is the verified Varta equivalent for the BATTERY-12SEM-180 tray. Compared with the BATTERY-12SEM-180 it has 1400 A of cold cranking more. It costs 277,50 € less. Decide by price, brand preference and availability: both fit and crank the same. ### Q-battery BATTERY-12SEM-180 or Exide EP1500: which one to choose? It is the AGM of the same size: sealed, maintenance-free and with far more discharge cycles than the BATTERY-12SEM-180. Compared with the BATTERY-12SEM-180 it has 900 A of cold cranking more. It costs 61,00 € less. Recommended for cyclic or stationary use, or when the equipment sits tilted; for occasional use the BATTERY-12SEM-180 does the job. ## Equivalent batteries - [VARTA M12](https://baterias.com/gb/battery-varta-m12-12v-180ah-1400a) ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team — automotive battery specialists since 2012. → https://baterias.com/gb/technical-team --- *baterias.com — Automotive batteries · 2026-11-07*
