![]() ![]() On stud terminals a test stud adapter should be used to obtain a better contact. To perform the test you will need a VAT (Voltage Amperage Tester) and a stopwatch. In order to perform the battery load test and get good results, the battery must be at at least 75% of charge (12.4V) or more. The load will lower the battery voltage and will be evaluated against a specification. The extra gasses generated can cause the battery to bulge and be short of hydrogen and oxygen later.Ī battery load test, as its name implies, is going to put a load on the battery. If that rate is exceeded, the battery will produce more hydrogen and oxygen than the electrolyte can recombine, which can cause excessive pressure in the battery. ![]() Charging a gel cell may require a special charger because the charging rate should be kept under 14.1 volts. The battery is also referred to as a recombinant battery, because during charging, oxygen and hydrogen are released from the plates and form water for the electrolyte. Since this battery won’t spill, it can be mounted in almost any position. The battery is sealed and uses special vents to hold pressure in the battery. The gel cell battery uses a special gelled electrolyte. A green eye is supposed to mean the battery is good however, the eye is in one cell only and gives no indication of the condition of the other five cells. The lack of fluid is an indicator that the battery is near the end of its life.Some maintenance-free batteries use a hydrometer “eye” to indicate the battery condition. If you don't see any fluid, you may want to replace the battery. Keeping the fluid levels full, will help extend the life of the battery. If it is low, add distilled water to top it off.
