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 100% 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.

BatteryTesting
1. The voltage of the battery needs to be measured.
2. If the voltage is less than 12.65 the battery needs to be charged with at least a six amp automotive style charger. A trickle charge will not work and could possibly ruin the battery if it is discharged. This needs to be done outside of the vehicle.
3. The battery needs to sit for 24 hours outside of the vehicle and the voltage tested again to see if the battery holds the charge.
4. The battery needs to load tested based on the maufacturers specifications to determine if the battery can pass a load test. The load test can only be performed on a fully charged battery.

Load Testing:
PURPOSE: generally performed because the battery is not performing as expected or as specified. This test will determine the battery’s overall condition and its ability to deliver an engine’s starting current requirement while maintaining a specific battery terminal voltage.
NOTE: Most Load Testers can be adjusted for the temperature of the battery. It is important to best determine the temperature of the battery and adjust the tester accordingly.
TEST PROCEDURE:
Step 1: Battery terminal voltage must be 12.60V or greater to test. If the battery voltage is below 12.60V, charge battery before testing.
Step 2: Connect the Load Tester cables and the test leads of a separate Digital Voltmeter (±0.25% DC accuracy, if the Tester has no direct DC Voltage Meter) to the battery terminals.
Step 3: Adjust the Tester Current Load to achieve ½ the Cold Cranking Amperage (CCA) rating of the battery and apply it for 15 seconds.
Step 4: At the end of 15 seconds, note the battery voltage on the Tester Voltmeter or the Digital Voltmeter and discontinue the test.
TEST EVALUATION:
This test is a pass or fail. Compare the recorded test voltage to the chart below. If the battery test voltage is above the appropriate voltage at the determined battery temperature, the battery tests OK. If the test voltage is below, then the battery failed and needs to be replaced.
