FAQ

What is the reserve capacity rating? What does that mean in the industry?

The reserve capacity of a battery is defined as the number of minutes that it can support a 25 ampere load at 80°F until its terminal voltage drops to 1.75 volts per cell or 10.50 volts for a 12V battery. Thus a 12V battery that has a reserve capacity rating of 100 signifies that it can be discharged at 25 amps for 100 minutes at 80°F before its voltage drops to 10.75 volts.

Is ODYSSEY® a completely dry battery?

Because the ODYSSEY® has no free acid inside the battery, it is covered under the US Department of Transportation (USDOT) unregulated "wet non-spillable wet electric storage batteries" classification and International Air Transport Association (IATA) "unrestricted" air shipments categories. These batteries may be shipped completely worry-free. Supporting documentation is readily available.

How much current is generated if I accidentally short an Odyssey battery?

As suggested before, the ODYSSEY battery is a very low impedance product, meaning that the short circuit current can be extremely high. For a series system (24V), the short circuit current will be of the order of 2,500 amperes; a 12V parallel system will generate close to 5,000 amperes!

You mentioned high impedance. What is it?

The impedance of a battery is a measure of how easily it can be discharged. The lower the impedance the easier it is to discharge the battery. The impedance of the ODYSSEY battery is considerably less than that of a marine battery, so its high rate discharge capability is significantly higher than that of a marine battery.

What does the abbreviation MF, GEL and AGM stand for?

MF stands for Maintenance free. A maintenance free battery is a sealed battery which you do not have to refill with fluid after use. MF batteries need, like every other battery, maintenance charging to provide the longest service life possible.

In a GEL battery, the sulphuric acid is bound in gel/solid form to decrease the risk of leakage and fluid losses.

AGM stands for Absorbent Glass Mat. In an AGM battery the electrolyte is absorbed in a glass fibre mat. AGM is a perfect starter battery. Because of the enhanced acid density within an AGM battery it needs charging with a higher current.
