{"title":"Start Stop AGM Batteries","description":"\u003cp\u003eLucas Start Stop AGM car batteries are designed for compatible vehicles that place repeated cycling and high electrical demands on the 12V battery. If your car was factory-fitted with an AGM battery, the correct replacement must also be AGM and must match the vehicle application, physical fit and electrical specification.\u003c\/p\u003e\n\n\u003cp\u003eAn AGM label alone is not enough to confirm compatibility. Use the vehicle registration or full make, model, year and engine first, then compare the battery already fitted. The safest choice passes three checks: it is listed for the exact vehicle, it matches the required technology and hardware, and the vehicle’s battery-management procedure is followed after installation.\u003c\/p\u003e\n\n\u003ch3\u003eWhat makes a Start Stop AGM car battery different?\u003c\/h3\u003e\n\n\u003cp\u003eAGM means Absorbent Glass Mat. The electrolyte is held within glass-fibre separators and the internal construction is engineered to tolerate the repeated charge and discharge activity associated with demanding vehicle electrical systems. AGM batteries are commonly specified for advanced Start Stop systems, regenerative charging and cars with substantial onboard equipment.\u003c\/p\u003e\n\n\u003cp\u003eThis does not turn an AGM starter battery into a general-purpose leisure or deep-cycle battery. Lucas Fusion AGM products in this collection are automotive batteries selected for compatible vehicle starting and electrical-support duties. Other Lucas AGM ranges serve different applications and should remain in their own collections.\u003c\/p\u003e\n\n\u003ch3\u003eIf the original battery is AGM, replace it with AGM\u003c\/h3\u003e\n\n\u003cp\u003eNever downgrade a vehicle originally specified with AGM to EFB or a conventional flooded car battery. A cheaper battery may share the same outer dimensions and terminal positions, but it is not built for the same cycling duty or the vehicle’s charging strategy. The wrong technology can age prematurely and may prevent the energy-management and Start Stop systems from operating as intended.\u003c\/p\u003e\n\n\u003cp\u003eSome vehicles originally fitted with EFB may permit an upgrade to AGM, but that is not a universal swap. Confirm the application and any required battery-management configuration before changing technology. This page is for cars whose fitment data calls for an automotive AGM battery, not for every vehicle displaying a Start Stop badge.\u003c\/p\u003e\n\n\u003ch3\u003eCheck the existing battery before ordering\u003c\/h3\u003e\n\n\u003cp\u003eOnce the vehicle finder has identified a Lucas option, inspect the fitted battery and compare all of the following:\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTechnology:\u003c\/strong\u003e look for AGM, Absorbent Glass Mat or VRLA\/AGM on the original label.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage:\u003c\/strong\u003e confirm the nominal voltage shown on the battery and in the vehicle specification.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCapacity:\u003c\/strong\u003e match the required amp-hour rating rather than selecting the largest figure that fits.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCold cranking performance:\u003c\/strong\u003e meet the specified CCA and compare figures measured to the same test standard.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCase size:\u003c\/strong\u003e measure length, width and total height, including the terminals.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTerminal layout:\u003c\/strong\u003e check positive-terminal position, terminal type and cable reach.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHold-down:\u003c\/strong\u003e confirm the base ledge or retaining arrangement used by the vehicle.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInstallation details:\u003c\/strong\u003e retain any vent connection, protective cover, heat shield and approved mounting hardware.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eTwo batteries described as 12V AGM can differ in length, height, polarity, capacity and starting output. Never modify cables, clamps or the battery tray to make an unconfirmed battery fit.\u003c\/p\u003e\n\n\u003ch3\u003eAh and CCA answer different questions\u003c\/h3\u003e\n\n\u003cp\u003eThe Ah rating describes electrical capacity under a stated test, while CCA indicates the battery’s ability to deliver starting current in cold conditions. Neither figure can be used on its own. A battery with more Ah is not automatically a better replacement, and a similar CCA does not compensate for the wrong technology or case.\u003c\/p\u003e\n\n\u003cp\u003eFollow the vehicle application data and keep the replacement within the approved performance class. This is especially important where the battery-management system has been calibrated for a particular technology and nominal capacity.\u003c\/p\u003e\n\n\u003ch3\u003eBattery registration, coding and reset requirements\u003c\/h3\u003e\n\n\u003cp\u003eMany modern cars monitor the 12V battery through a battery energy-management system. Depending on the make, model and system, a new battery may need to be registered, coded, adapted, initialised or reset after fitting. Other vehicles use a self-learning process. There is no single procedure that applies to every Start Stop car.\u003c\/p\u003e\n\n\u003cp\u003eRegistration tells the vehicle that a fresh battery has been installed so its stored battery-age information and charging control can be handled correctly. A diagnostic process may ask for battery technology, nominal capacity, manufacturer information, a serial number or another vehicle-specific value.\u003c\/p\u003e\n\n\u003cp\u003eCheck the exact procedure before disconnecting the old battery. If specialist diagnostic equipment or a controlled support-voltage procedure is required, use a competent technician. Do not copy a button sequence from a different model or assume that a dashboard warning will clear in the same way on every car.\u003c\/p\u003e\n\n\u003ch3\u003eProtect the battery sensor and approved connections\u003c\/h3\u003e\n\n\u003cp\u003eA battery current or temperature sensor is often fitted around the negative terminal or earth lead. It forms part of the vehicle’s energy-management system. Keep the original sensor, terminal assembly and cable routing intact, and use the vehicle manufacturer’s approved connection points for chargers or accessories.\u003c\/p\u003e\n\n\u003cp\u003eBypassing the sensor or moving accessory earth connections without checking the vehicle instructions can prevent the system from measuring battery current correctly. If the terminal assembly is damaged, loose or heavily corroded, have it inspected rather than treating it as an ordinary clamp.\u003c\/p\u003e\n\n\u003ch3\u003eStart Stop not working does not automatically mean battery failure\u003c\/h3\u003e\n\n\u003cp\u003eA car can deliberately inhibit automatic engine stop even when the battery is serviceable. Battery state of charge, ambient temperature, engine temperature, cabin heating or cooling demand, heated screens, steering input, repeated short journeys and other operating conditions can all influence availability. Vehicle faults may also disable the function.\u003c\/p\u003e\n\n\u003cp\u003eIf the engine no longer stops automatically, do not order a battery from that symptom alone. Check the owner’s manual, scan for relevant faults and test the battery and charging system. A correct diagnosis avoids replacing a healthy battery while leaving the actual cause unresolved.\u003c\/p\u003e\n\n\u003ch3\u003eTest the whole starting and charging system\u003c\/h3\u003e\n\n\u003cp\u003eSlow cranking, warning messages, repeated flat batteries or unreliable Start Stop operation can result from more than normal battery ageing. Poor terminal connections, alternator or charging-control faults, an excessive key-off electrical drain and unsuitable charging history can produce similar symptoms.\u003c\/p\u003e\n\n\u003cp\u003eUse test equipment with an AGM setting and interpret the result alongside the battery’s age, state of charge and vehicle condition. A resting-voltage reading by itself does not provide a complete battery health assessment. Where a replacement repeatedly loses charge, investigate the vehicle rather than repeatedly replacing or charging the battery.\u003c\/p\u003e\n\n\u003ch3\u003eShort journeys can leave an AGM battery undercharged\u003c\/h3\u003e\n\n\u003cp\u003eEvery engine start removes energy. On a car used mainly for short or infrequent trips, the journey may not always replace what was consumed by starting, security systems, heating, lighting and other electrical loads. The result can be a gradual state-of-charge deficit even though the alternator is functioning.\u003c\/p\u003e\n\n\u003cp\u003eWhen external charging is appropriate, use a quality charger with a mode approved for 12V automotive AGM batteries and follow both the charger and vehicle instructions. Connect at the specified points, particularly on cars with a battery sensor. Avoid uncontrolled boost charging and never select a repair or high-voltage mode while the battery remains connected unless the vehicle manufacturer explicitly permits it.\u003c\/p\u003e\n\n\u003ch3\u003eBattery location can change the fitting procedure\u003c\/h3\u003e\n\n\u003cp\u003eThe 12V battery may be under the bonnet, beneath a seat, in the boot or behind interior trim. Access can involve retained settings, powered seats, vent tubes, covers or model-specific disconnection steps. A sealed AGM construction does not remove the need to refit the original venting and protection where supplied.\u003c\/p\u003e\n\n\u003cp\u003eBefore starting work, read the vehicle procedure and make sure the replacement can be safely lifted into position. A large AGM car battery is heavy. It must sit correctly in the tray and be secured with the original approved hold-down so it cannot move during braking or cornering.\u003c\/p\u003e\n\n\u003ch3\u003eSafe replacement and recycling\u003c\/h3\u003e\n\n\u003cp\u003eSwitch off the vehicle and keep keys away from keyless-entry cars as directed. Remove metal jewellery, prevent tools from bridging terminals and follow the manufacturer’s terminal disconnection and reconnection sequence. Never work on a damaged, leaking, swollen, frozen or unusually hot battery.\u003c\/p\u003e\n\n\u003cp\u003eAutomotive batteries contain lead and acid and must not go into household waste. Keep an old battery upright, protect the terminals against short circuit and take it through an appropriate battery-recycling route.\u003c\/p\u003e\n\n\u003ch3\u003eFind the correct Lucas AGM car battery\u003c\/h3\u003e\n\n\u003cp\u003eUse the products above only after checking the exact vehicle fitment. Popular references such as LF027, LF096, LF115, LF017 and LF020 represent different case sizes and performance levels; they are not steps in a simple “small to large” upgrade path.\u003c\/p\u003e\n\n\u003cp\u003eIf you are unsure, send us the vehicle registration and a clear photograph of the complete existing battery label, terminals, hold-down and installation area. Tell us whether the battery is original, whether the vehicle has Start Stop and whether any diagnostic or battery warning is displayed. We can help compare the suitable Lucas AGM options and flag where the vehicle’s fitting information indicates a registration or reset requirement.\u003c\/p\u003e","products":[{"product_id":"lucas-agm-lf017-car-battery","title":"Lucas AGM LF017 12V 95Ah Start Stop Car Battery","description":"\u003cp\u003eLucas AGM LF017 Car Battery from the Lucas AGM range.\u003c\/p\u003e\n\u003cp\u003ePlease check the specifications below to confirm this battery matches your existing battery or vehicle requirements.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart number:\u003c\/strong\u003e LF017\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUK part number:\u003c\/strong\u003e 017AGM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage:\u003c\/strong\u003e 12V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCapacity:\u003c\/strong\u003e 95Ah\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCCA:\u003c\/strong\u003e 850 EN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 354 x 175 x 190 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTerminal layout:\u003c\/strong\u003e 0\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHold down:\u003c\/strong\u003e B13\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 26.4 kg\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eNeed help choosing the correct battery?
