What is Drycell?

Pure virgin lead; not corrosive in sulfuric acid.

Grids can be made extremely thin.

Thin grids allow more plates per cell.

More plates = more plate surface area.

More surface area for chemical reaction.

Result - 40% greater pulse discharge power, especially for first 5 seconds.

Worlds only pulse power and true deep cycle - all in one battery.

40% more 5 second cranking amps.

400 cycles to % depth of discharge.

High pressure sealed design, explosion-proof and completely safe for in passenger compartment mounting.

Batteries are certified by USDOT and IATA as non-hazardous, nonspillable for shipment by UPS or air transport.

Exclusive 4 year full limited warranty against factory defects materials or workmanship on PC 2150.

Exclusive pure-lead design (not gel) offers performance capabilities not available from conventional batteries.

Metal jacketed vs. Non-metal jacketed: The metal jacket is needed if it's being mounted near heat to protect the plastic of the battery from swelling. The lead plates are under much higher pressure than a lead acid battery and if the plastic heats up, the plates will want to expand outward which can ruin the battery if it doesn't have a jacket.

Cold Cranking Amps: For all the power, durability, and life of our technology, the cca ratings can seem disapointing. That's because the cca ratings are often misunderstood. Odyssey batteries are SLI (starting, lighting and ignition), so if you are looking for a starting or reserve battery the cold cranking numbers can be irrelevant.

The "standard" cca test measures the output of a battery for 30 seconds of crank at 0 degrees with the ending voltage of the battery being 7.2v. Some companies use 15 or 20 seconds and some companies use 32 degrees which can make for better results.

A vehicles starter isn't designed to withstand 30 seconds of cranking so we feel the batteries starting power is more important. The Odyssey part numbers represent the 5 second cranking power of the battery.

The PC680 is rated at 680 amps for 5 seconds, 595 amps for 10 seconds, and 525 amps for 20 seconds. Cranking power is even higher for the first four seconds. Similar sized lead acid batteries are only rated at 180 - 220 amps.
