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
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.
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
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
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.
Step 1: Battery terminal voltage must be 12.60V or greater
to test. If the battery voltage is below 12.60V, charge battery
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
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
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.
