Can be very pricey compared to other ‘portable’ battery chargers.Unique float mode helps maintain the integrity of the battery.Plug-and-play type of interface guarantees effortless charging.Small enough footprint that will not take too much space.
Multiple functions: jumpstarting, boosting, maintaining, and charging.You can store your battery and the SC1305 will make sure that it has enough juice when you put it back in your car. This helps keep the battery charge at optimal levels. The technology attempts to repair damaged cells by removing Sulfation.Īnother important feature of the Schumacher SC1305 is the float mode monitoring. This is perfect for cars that have traditional wet cell batteries. The system also comes with an automatic desulfation mode. It then automatically adjusts the power ratings to help save your battery. It keeps track of the type and size of battery that is connected to the device’s charging cables. Counties include Maricopa County, Pima County and Gila County.An intelligent microprocessor is behind this innovative technology.

However, when charging an automotive battery, 10 amps or less is considered a slow charge, while 20 amps or above is generally considered a fast charge. Slow charging rates vary depending on the battery's type and capacity. How do you know the best method to charge your battery? We've outlined the difference between a slow charge and a fast charge for you. Step 4: Use a voltmeter or check the battery cells with a hydrometer to make sure the battery is fully charged. Even after nine hours, because of the reduced voltage, the battery may require more charging to get it 100% charged. For that reason, it can easily take nine hours or more to fully recharge the battery. You may actually only see about half the output over the time period that you are actually charging the battery. (The best charger to use to charge a car battery is a 3-stage automatic 12 volt/10 amp charger.) The charger doesn't really output the entire 10 amps during the charge cycle because it automatically limits the voltage and the amperage during the charge cycle. Using the example above, it would take around 4.5 hours to recharge that battery. Take the amount of amp-hours needed by the battery and divide it by 10 amps. Step 3: Charge the battery at a 10-amp rate.

It's necessary to put about 36 amp hours, plus 15% more to compensate for the internal resistance in the battery, for a total of 36 amps + 36 x 0.15 = around 42 amp- hours back into the battery. This means there are about half of the 72 amp hours in the battery. For example, if the voltmeter shows a voltage reading of 12.4 volts, then the battery is about only 50% charged. Step 2: Before charging a battery, use a voltmeter to measure the remaining voltage in the battery. In the case of a MT-34, 120 minutes RC x 0.6 = about 72 amp-hours (at a 20-hour rate). In order to calculate the amount of amp- hours in a battery, multiply the reserve capacity by 0.6.
For example, an Interstate battery with the part number MT-34 has 120 minutes reserve capacity (RC). Step 1: Determine how long to recharge a battery by calculating how much capacity your battery has.
