3 Steps to Resurrect Your Battery --- Easy To Use
What is battery sulfation ?
When lead-acid batteries are in a discharged state for any length of time, sulfation will build and will decrease the battery’s capacity. If left unused and discharged for enough time, sulfation will eventually render a battery useless.

Will RD510 Charge and desulfate (Repair Mode) your battery ?
Yes,Romondes RD510 Battery battery desulfator can charge and desulfate your battery.Sulfation Accounts for Many Early Battery Failures,If you have ever had a battery that died before the end of its expected lifespan, sulfation may have played a role. Sulfation ranks as a common cause of early failure for lead-acid car batteries. Even before it causes your battery to die altogether, sulfation affects your car in a number of potentially debilitating ways.
(Note: The pulse repair function can only be used when the car battery is disconnected from the car.)
Sulfation Affects and how to prevent it ?
One of the most common causes of sulfation involves batteries that remain perpetually undercharged. If your battery never charges all the way, it won’t reach a state of full saturation. On a chemical level, such undercharging makes it much easier for sulfate crystals to form. A fully charged battery, by contrast, possesses a charge enough to minimize sulfation.
How long does it take to Desulfate (Repair Mode) a battery ?
Depending on the size of the battery, the desulfation process can take from 48 hours to weeks to complete. During this period the battery is also trickle charged to continue reducing the amount of lead sulfur in solution.Repair Mode will be end automatically after completed.

3 Functions of Auto Battery Tester
 |  |  |
| BATTERY TESTING The battery test mainly aims to analyze the battery's health status to calculate the cold cranking capability of the cattery and the aging extent, which provide reliable analysis evidence for the test and maintenance of the battery. | CHARGING TEST Checking and analyzing the charging system, including generator, rectifier, rectifier diode, etc., thus to find out whether the output voltage of the generator is normal, the rectifier diode works properly and the abnormal. | CRANKING TEST Be used to test and analyze the starting motor. Testing the actual required cranking current and cranking voltage of the starting motor is helpful to determine whether the starting motor works properly or not. |
