Product Information

This world beater battery, Using TPT (thin plate technology) is a must when size and weight are not critical, but where amp/hour and sustained cranking or long periods of abusive use demand exceptional ruggedness. Proven in the harshest of Trans-African rallies and fitted to many Porsche Race cars, the PC925 has a superb reputation.

The ODYSSEY PC925 is popular in endurance racing events including the LeMans 24 hours. Exceptionally good anti-vibration properties are matched with a 29 a/hr capacity and fast recharge capability with good recovery from heavy discharge. Can be mounted upright or flat. Design life of 8-10 years.

Used extensively in Powervamp's military products the PC925's proven vibration resistance, ultra high discharge performance and a flame retardant casing are its key features. For applications where high loads are present or where street legal vehicles have a need for amp/hour capacity, then this battery is an ideal compromise in terms of amp/hour capacity versus size / weight It is ideal for large capacity V8's up to 5.0 litre

The Odyssey Extreme Series

Odyssey batteries hold up to twice the overall power of conventional batteries, doing double the duty, therefore giving double the performance.

The Odyssey Extreme Series available from Alliance Electronics offer both enormous cranking power and deep cycle reserve power, giving you the best of both worlds.

Even at very low temperatures, Odyssey Extreme batteries have the power to provide engine cranking pulses in excess of 2250 amps for 5 seconds – double to triple that of equally sized batteries on the market. With the ability to handle 400 charge-discharge cycles, they are as robust as they are reliable.

The Odyssey Extreme Series are made with flat plates made of 99.99% pure lead, not lead alloy. This additional purity allows for thinner plates, meaning each battery can hold more at a time, thus providing the plate surface area required for additional power. That's how Odyssey Extreme batteries produce twice as much power as conventional batteries.
