Car Batteries

The car battery is the heart of your vehicle's electronics system. With an underperforming battery or a poor quality product fitted your car will never perform how the manufacturer intended.

We recommend fitting the highest quality car battery that your budget will stretch to to get the ultimate performance from your car over the longest period possible. The old adage 'Buy Cheap, Buy Twice' certainly holds true in the car battery world. We test each battery that we stock and for each size we recommend a 'Star Buy' check underneath your chosen battery for the 'Star Buy' product.

Car Battery Technology

Car battery technology has progressed rapidly over recent years with developments such as calcium technology becoming widespread, effectively enabling all car batteies to now be maintenance free.

Flooded Lead Acid Car Batteries

If you think of a traditional wet car battery which must be kept upright to avoid spillage, you're thinking of a flooded lead acid battery. This is a plastic case filled with sulphuric acid and featuring six lead plates, each of which produces around 2 volts of power. The six plates are combined to give an output of 12 Volts. As flooded cell batteries are charged by the car's alternator gas is produced along with evaporation so traditionally you have had to monitor the levels of electrolyte, topping up with distilled water when required. Developments such as calcium technology have led to far less gassing and hence less evaporation meaning modern batteries are maintenance free.

Flooded cell batteries are an extremely simple concept so are cheap to produce, meaning they are our cheapest car batteries. See our Numax Car Batteries for cheap flooded acid car batteries.

AGM Car Batteries

AGM is a newer technology of car battery which is similar in principle to flooded cell batteries, but with a vital difference. AGM Car Batteries hold the electrolyte in a fibreglass matt within the battery. This construction method makes AGM batteries non-spillable so they are completely safe to handle. Safety is only one benefit; another benefit is increased cycle life meaning AGM batteries can withstand three of four times as many charge-discharge cycles as flooded lead acid batteries. Another benefit is increased starting power; AGM batteries have higher CCA (cold cranking amps) figures so have higher starting power compared to lead acid batteries. The only downside to AGM batteries is that due to their high quality construction they can be more expensive.
