Battery FAQS & TIPS
Typical Questions and Answers and Definitions
AMPS - Flow of energy or capacity of battery. The “Continuous Amps” are the maximum continuous charging/discharge rate that the battery can easily handle. See also “CRANKING AMPS”.
BAR HOPPING & CHARGING - When a vehicle starts, a large amount of energy is drained from a typical battery. Regular batteries take a few minutes (sometimes 10 minutes to recharge the battery from the engine), and typically can only last a few quick stops. Our battery recharges very fast (about 15 seconds) and therefore is not likely to ever eliminate the reserves in the battery allowing unlimited numbers of bar-hopping. This feature also allows a completely dead battery to accept a fast charge (like one minute) to contain enough charge to easily start the motor. Most completely dead acid batteries will not accept a charge after setting dead. Even “almost dead” acid batteries take hours of charging before they can be successful in starting an engine.
BATTERY CHARGING - See “CHARGING”
BATTERY MINDER - See “CHARGING”
CHARGING - All batteries must be charged with an appropriate charger that does NOT exceed 14 volts of charging voltage. Most chargers are appropriate that work on lead acid batteries and that are generally sold at most retail stores. Most are called “smart” or “automatic” chargers and will work fine. To be certain, measure and monitor the charger and battery to be certain that 13.5 volts are the maximum volts delivered to the battery. It is virtually impossible to charge batteries with excessive amperage, as those types of chargers cost many hundreds of dollars and have special instructions, settings, and features to prevent damage. Broken alternators or charging outside of stated limits can result in battery damage that is NOT covered in this warranty, excessive heat, melting, fire, damage and possible injury. Trickle chargers, maintenance chargers, battery tenders, battery minders, etc. should not be left connected for more than two hours (or less if suggested by charger manufacturer). Continuous charging is seldom necessary unless you have continuous battery drain or allow long months between use of vehicle. Abusive charging will void warranty. ALL NEW PACKS SHOULD be checked before use. That means check polarity and voltage before hooking up to your charger or electronics. We do our best to insure all batteries leave correctly but let’s put safety first.
CONTINUOUS AMPS - See “AMPS”
CRANKING AMPS - The “10 second High Amps” is similar to “Cranking Amps” or “Burst Amps” and is intended as a way to compare our battery while cranked (with coil wire disconnected). The maximum amps that can be safely discharged (or charged) for short periods of time. See also AMPS.
DIMENSIONS - See “FORM FACTORS”
FAST CHARGING - See “CHARGING”
FORM FACTORS - The measurements and styles available are multiplied by the different styled posts and locations. For that reason, we include rulers in many of the photos. We also state larger measurements than the actual batteries when we estimate sizes. The photos and rulers are real. The written statistics are estimated.
MAINTENANCE CHARGING - See “CHARGING”
SAG - See “VOLTAGE SAG”
TRICKLE CHARGING - See “CHARGING”
Seller will issue a refund for returned shipping only if the return is due to product malfunction under the above warranty period. The return shipping method must be UPS ground or USPS Priority with tracking. Any expedited services that are not covered are at the customers own expense. Customer will contact us before shipping any product back to get authorization. Returns sent to us with no explanation or prior authorization may not receive a refund or be sent back. It is very important that you contact us via email with your problem first. At the very least, include a detailed explanation of the problem in with your return. If approved by email from Seller, simply include a printout of that email with your return. Again, failure to include this information may result in product loss and/or no refund. All returns must include a note that states the exact reason for return. Reconfigurations or repairs from your own damage do not qualify for shipping refunds of any type. Unless otherwise stated, customer is entitled to a replacement or refund within 30 days from ship date if the pack fails to perform properly or is defective. Delivered merchandise that is broken in shipment must be refused at time of delivery. After acceptance of delivery, Seller is released from broken merchandise warranty. Recourse for broken merchandise is solely with shipping agent after acceptance of delivery. NOTE: See Warranty for exact terms and conditions.
VOLTAGE SAG - Typical batteries start at about 12 volts when fully charged. Upon cranking, they lower (sag) the available voltage to about 10 volts in a few seconds and continue to get lower until failure at about 15 seconds or 8 volts of sag. Our batteries are completely different. Ours do NOT sag noticeably and provide more than four times as much reserve capacity at full voltage, until eventually they run out of energy quickly. This allows for far less heat with our batteries on wires, connectors, starters, and on the batteries themselves. The fast charging/power use of our batteries is partially from the lower resistance of our batteries, thereby lowering heat and wasted energy of the whole electrical system, especially under extreme load.
