There are three ways to evaluate car batteries:
Cold start ampere (CCA) is a measure of the ability of a battery to start an engine in extremely cold weather. Our Lead Acid Battery Manufacturers use refrigerators to simulate winter conditions, cool the batteries to 0°F, and rate the batteries based on their performance. We believe that our test is based on more realistic charging voltage and amperage requirements compared to the test of a typical manufacturer, and our results show the relative starting power of each battery, regardless of the manufacturer’s claims.
The reserve capacity indicates how long the battery can run the vehicle if the charging system (alternator, stator, and rotor) fails. This is also a measure of how long you can inadvertently turn on the headlights and still start the car without a quick start. In order to test the reserve capacity, our engineers measured the time required for a fully charged 12v Deep Cycle Gel Battery to discharge to 10.5 volts (considered as fully discharged). At this level, if there is no quick start, the car will not start. We think that an average of 1.5 hours of electricity is required. Models with higher scores can supply power within 2 hours.
The battery life is measured by repeatedly discharging each 12v Deep Cycle Gel Battery at a test temperature of about 167°F for about 3,000 times and charging for 15 weeks or until the performance drops to an unacceptable level. This simulates the high-temperature hood conditions that the battery may face in the summer, which is the most uncomfortable time of the year for the 12v Deep Cycle Gel Battery because of the heat. Frequent high temperature is very unfavorable to the battery, it will aggravate the corrosion of the electrode plate, and make the electrolyte needed for the current vaporize faster. If you take many short trips and don't have much time to recharge, long life is especially important. The higher the score, the more reliable the battery.
