FAQ

Why Extreme Series?

Everything started with the Extreme Series - most people wouldn't know there are two ranges within the Odyssey brand. That's because it's not really a difference but more of a targeted market. The majority of the Performance Series batteries are part of the BCI sizing dimension which means they are commonly used sized globally. The Extreme series, however, is where batteries and the brand were born. Batteries can be used for a variety of applications and a high-performance UPS battery was where it all started some 25 years ago.

A battery that once started life as a stationary battery for high power discharge with a few tweaks became the PC680, the PC925 & the PC1200. That's where it all began more cranking power than anything else on the market, metal jackets for impact and additional heat dispersion or cold weather protection. These common sizes in UPS where new to Automotive and hence the fascination with small lightweight but powerful batteries for race car or aftermarket upgrade were born. The range has since grown to over 23 models most of which we keep in stock.

EFB batteries, what are they?

Extended Flooded Batteries or Enhanced Flooded Batteries. They are now being commonly used in Start Stop Vehicles (vehicles that stop the engine when you stop the vehicle and restart when you push on the accelerator) because of the high cranking demand. The irony is that an AGM batteries were designed for this purpose some 50 years ago but it's all about costs, not quality.

What is Pulse Hot Cranking Amp rating?

Unlike CCA and MCA the pulse hot cranking ampere (PHCA) rating does not have an "official" definition; however, we believe that for true engine start purposes, a 30 second discharge is unrealistic. With that in mind, the PHCA is a very short duration (typically about 3 seconds) high rate discharge. Because the discharge is for such a short time, it is more like a pulse.

What does TPPL mean?

It stands for Thin Plate Pure Lead. It's used to describe the plates which are at the heart of the technology. It's what makes Odyssey better than other batteries. The plates are actually a punched grid from continuous roll virgin lead so they are all exactly the same in every way size and dimension, weight, grid, unlike a cast plate which is never the same from pour to pour. Because of the consistent quality all batteries perform exactly the same which makes them easy to pair when matched sets are required.

Define the difference between MCA and CCA.

The marine cranking ampere (MCA) rating of a battery is very similar to the CCA rating; the only difference is that while the CCA is measured at a temperature of 0°F, the MCA is measured at 0°C. All other requirements are the same — the ampere draw is for 30 seconds and the end of discharge voltage in both cases is 1.20 volts per cell. or 7.2 volts for the whole battery.
