At the Detroit motor show this morning, Ford unveiled its new Fusion mid-size passenger car, which will arrive in Europe wearing Mondeo badges late this year or early next.
At first glance the new car looks very similar to the current Mondeo, but direct comparison reveals more shapely sculpted sides, door-mounted mirrors, a more prominent shoulder crease that runs all the way forward to the slimmer headlamps, and a new nose that owes a heavy debt to Aston Martin. Of more interest to green motoring fans is the revelation that Ford aims to deliver class-leading economy from three different iterations of the US-market Fusion.
The US market will also get a hybrid and a plug-in edition of the Fusion, but there has been no announcement about whether either will be sold in Europe. The Fusion Hybrid will feature a new 2.0-litre, Atkinson-cycle four-cylinder petrol engine, and will be able to run at up to 62mph on its lithium-ion batteries. And finally the Fusion Energi plug-in hybrid is scheduled to arrive in the autumn, with Ford promising to trump the miles per gallon offered by both the Toyota Prius plug-in and the Chevrolet Volt.
Meanwhile, Mercedes-Benz has revealed its riposte to BMW’s upcoming ActiveHybrid 5 in the shape of a new hybrid E-Class. The new E300 will join the growing throng of diesel-based hybrids, its 27bhp (20kW) electric motor joining forces with a 204bhp, 2.1-litre four-cylinder turbodiesel. The motor is installed between the E300’s engine and its seven-speed automatic transmission, sitting aft of a wet clutch that has ousted the usual torque converter. Unusually, the hybrid system’s high-voltage battery has been squeezed under the bonnet and has supplanted the usual 12-volt lead-acid lump.
Amp Hour (AH) – typically used for deep-cycle batteries, this illustrates the amperage capacity. The other side of the label tells you the type of battery and usually features a purchase date selection used for warranty purposes.
While most batteries are of the same age-old lead acid (LA) design, there are many ways to put them together.
Gel– The platform is the same, but instead of using plain old water as the base for the electrolyte, they use a thickened version (like Jell-O) to keep the electrolyte from leaking in the event of a cracked or broken box. AGM – AGM or Absorbed Glass Mat batteries are the most efficient of the lead-acid design. Both gel and AGM batteries de-gas like flooded batteries, but since they are sealed, the gasses are reabsorbed into the electrolyte, keeping them functional longer. Starting batteries – have higher cranking amps for heavy, short bursts of energy use a larger number of thinner plates to release more amperage.
Deep-cycle batteries – use fewer plates, but each plate is thicker, so they store more energy, but can’t release it as fast, only 25% of the rated amperage can be released at one burst. Flooded style deep-cycle batteries should not be used for starting; they do not have the cranking power. There are a couple of newcomers to the automotive battery realm, specifically lithium Ion (Li) and Nickel-Metal Hydride (NiMh). NiMh – This design uses hydrogen-absorbing alloy as the negative electrode, and nickel oxyhydride as the positive side. Li – Lithium batteries are very similar to NiMh batteries, but they are slightly more efficient and hold a static charge for longer periods. Long-term storage or even a couple of days in frigid temperatures can weaken a batteries charge. Charging – When storing a battery long term, you should consider a trickle or maintenance charger.
Corrosion – Corrosion is a problem with all batteries, moisture, metal and electricity cause electrolysis, the same process at work inside the battery, but in an uncontrolled manner. Water Level – Flooded batteries require water to function, over time, the water level decreases. This type of terminal connection can get you home in a pinch, but must be replaced as soon as possible.


Cables and Terminals – The battery can only do its job when the connections are good. Today brought news of two new and very significant cars that should arrive before this freshly unwrapped year is out. Daniel Craig did briefly drive a Mondeo in Casino Royale, before winning his signature DB5 at the card tables, but it seems a safe bet that nobody will mistake the new Ford for James Bond’s ride no matter what mask it wears.
A 1.6-litre EcoBoost engine, already available in Europe, will be offered in the new US market car. But while the hybrid 5-Series will put pace firmly before frugality, the Mercedes will follow a more economical blueprint. Torque will not be in short supply, with 500Nm available from the engine room alongside another 250Nm on tap from the motor. Separating the motor and engine with a software-operated clutch allows the motor to propel the car unaided while the engine switches off. This will allow the diesel unit to periodically switch off for as long as the battery reserves hold out (which won’t be very long at 99mph). There has been no word yet on likely costs – no doubt we will find out when the E300 hybrid goes on sale before the end of the year. While the type of battery under the hood is not likely to give you any horsepower gains, it will save you from having to get jump started in the middle of the night at the gas station. This is the most important measure of a battery, and is the typical rating used for selecting the appropriate battery for a vehicle. A battery with 150 amp hours rating would provide 15 amps for 10 hours, 10 amps for 15 hours or 150 amps for 1 hour. Sealed flooded battery are designed to be maintenance—free, meaning you don’t have to add water at any time, they are sealed.
This also makes the battery more stable in terms of vibration and installation location, as the gel doesn’t move, which ensures the plates are always covered in electrolyte. Both types of batteries can release their charge faster than flooded batteries, which is an important function. Deep cycle batteries are used for long-term constant draw situations, such as boats, golf carts and show cars (lights and stereo systems). These batteries are commonly used in rechargeable applications for cell phones and other portable devices, they are very stable and hold a charge for a long period of time, with the ability to release that charge quickly. These batteries are becoming more prevalent in high-performance applications where every pound is critical.
These low-amp chargers keep the battery from discharging over time without boiling the electrolyte, which can ruin the battery.
Corroded cables and terminals, loose fitting terminals, etc limit the alternator’s ability to charge the battery and provide juice to the car. A daily-driven econobox doesn’t need a high-performance lithium-ion battery, while a show car needs a battery that can sustain long periods of use without charging. His career began in the car audio industry as a shop manager, eventually working his way into a position at Rockford Fosgate as a product designer. In urban electric-vehicle mode, the car can manage about one kilometre at up to 22mph before the engine fires up. Additionally, a properly functioning battery means your alternator doesn’t have to work as hard, and getting the best performance from your charging system is always good bet, especially if you have upgraded electronics. All lead acid batteries use the same overall concept – lead plates (one is lead, the other is lead oxide) are submerged in an electrolyte solution of sulfuric acid.
Within a conventional battery, such as a “tar-top” battery in a classic car, each LA cell is separated and each group has its own electrolyte. One of the drawbacks for gel cell batteries is that they are more susceptible to voltage irregularities and they can’t be refilled, once the electrolyte degrades, the battery is toast.


In order to provide a larger level of cranking amperage, a flooded battery must be much larger, as a typical flooded battery is limited in how much charge it can release at one time. The side effect of this is that the plates get hotter faster, which causes them to warp and pit, particularly when they are fully discharged.
Leaving a LA battery on the shelf for 6 months will degrade the battery, especially if it is in cold weather. Find the right battery for your needs and it will serve up the juice you need for a long time. In 2003, he began writing tech articles for magazines, and has been working as an automotive journalist ever since. Each of these plate groups is called a cell; a group of individual cells is called a “battery”.
Over time, the process of charging and discharging uses up the electrolyte and it has to be replaced with distilled water. NAPA offers an AGM type battery in the Legend series, which uses a flat-plate core with AGM electrolyte separators, making it impossible for the plates to touch.
In fact, Porsche recently swapped out conventional batteries for Lithium Ion, with a replacement cost of $1700. A dead flooded (this does not work for gel or AGM types) battery that won’t hold a charge can sometimes be “jump-started” by boiling the electrolyte with a heavy high-amperage charge. You have to be careful with side-post terminals, as you can strip the threads and actually break into the case, causing electrolyte to leak out. His work has been featured in Car Craft, Hot Rod, Rod & Custom, Truckin’, Mopar Muscle, and many more. As the battery discharges, the lead electrodes become lead sulfate, and the electrolyte dissolves into water. These batteries last much longer than a conventional or gel-cell battery, and are the superior design for wet-acid type vehicle batteries. This means that gel cell and AGM batteries can fit in a smaller case while providing more amperage. Using an Li battery in cold weather is not advisable though, as they can be damaged in temperatures below freezing. In severe cold weather a battery can freeze, which will short out the plates and the battery will no longer charge.
This why batteries freeze during the winter, which can cause the lead plates to touch (short-circuit), effectively destroying the battery. Jefferson operates Red Dirt Rodz, his personal garage studio, where all of his magazine articles and tech videos are produced.
While charging a lead acid battery, through electrolysis, the battery generates oxygen and hydrogen gas, which can be explosive, which is why batteries are typically mounted under the hood, where they dissipate and do not become condensed. When installing a battery in the trunk, a firewall must be installed to protect the passengers; the battery box must also be vented to the exterior of the vehicle. The process for reviving AGM batteries is a little more complex, involving multiple batteries chained together.
Another solution is liquid electrical tape, which creates an airtight seal, but it has to be cut off before removing the battery cable. AGM batteries need a better quality charger than a standard flooded battery, Optima Batteries offers an AGM-specific charger that doubles as a conditioner for long-term storage.
