# Battery for MG in Málaga > MG battery (ZS, HS, MG4)? 12 V auxiliary on electrics, EFB on petrol. Official Varta Distributor, no appointment in Málaga. Coding included. Home › Car batteries › Batteries by brand › MG The service battery in an MG is a 12 V unit : in the electric MGs (MG4, ZS EV) and in the EHS plug-in it is an auxiliary AGM or EFB battery that switches on the electronics and powers the ignition —it does not start the car, that is handled by the high-voltage battery—, while the petrol MG ZS and HS with Start-Stop use a 12 V EFB of around 60-70 Ah. At Málaga Baterías (C/ La Orotava, 100, 29006 Málaga), Official Varta Distributor since 1999 , we test it for free and replace it without an appointment, in about 15 minutes , with coding included. Guide prices with fitting: 85-140 € conventional, 130-230 € EFB and 180-280 € AGM. Your MG won't start or won't go READY? Today and without an appointment Send us your number plate on WhatsApp and we'll tell you the exact battery for your MG and the price in minutes. Call now WhatsApp MG has taken over the streets of Málaga in a very short time, above all with the MG ZS and the wave of electrics and plug-in hybrids (MG4, ZS EV, EHS). And that is the key point: in an electric or plug-in MG the battery we usually replace is the 12 V auxiliary one , not the traction battery. It is small but critical: if it runs flat, the car won't switch on or go READY even when the big battery is full. We sort it out on the spot, without an appointment and with coding included, at C/ La Orotava, 100, 29006 Málaga . We work in the shop : we do not offer home fitting. Which battery does an MG take? MG belongs to the SAIC group and has a range heavily geared towards electric and plug-in cars. That changes the type of 12 V battery depending on the version, so it is worth telling them apart. Guide values, all 12 V : Model Typical technology Start-Stop Note MG ZS (petrol) EFB 60-70 Ah Yes Reset the energy system when replacing MG HS (petrol / EHS PHEV) 12 V EFB (auxiliary on the EHS) Yes On the EHS plug-in, the 12 V is auxiliary MG ZS EV Auxiliary 12 V AGM or EFB — Doesn't start; provides ignition and READY MG4 (fully electric) Auxiliary 12 V AGM or EFB — Auxiliary; if flat, no READY MG3 (petrol / hybrid) Conventional or EFB Depends on version Confirm it with the number plate Guide values: they change with the year, trim and equipment. «—» = data we confirm with your number plate. The quirk with MG is in its electrics and plug-ins: the 12 V is an auxiliary or service battery (AGM or EFB) that switches on the ignition, wakes up the screen and lets the car go to READY , but it does not start any engine —moving the car is the job of the high-voltage battery, which is a different thing—. On the petrol MG ZS and HS with Start-Stop the 12 V is an EFB : if it left the factory with EFB or AGM, you must keep that technology. You can step up from EFB to AGM, but never down from AGM to EFB . Official Varta Distributor since 1999 Varta batteries for your MG, fitted on the spot We are at C/ La Orotava, 100, 29006 Málaga.
