Get the mandatory gear: You will want a battery or team of batteries, a discharge load, and a means to evaluate the voltage and current from the battery or battery group.
The pressured discharge exam typically begins with a fully demand the battery to its rated potential to determine a baseline for efficiency. The battery is then discharged in a drastically greater recent than its rated specification, generally until eventually it reaches a critical voltage amount.
Batteries are made to past for many charge/discharge cycles, so several discharge exams carried out as Portion of servicing usually do not have an affect on a battery’s services existence.

A highest of 1 downtime period of either 6 minutes or ten% of your exam duration (whichever is shorter) is permitted, plus the tester decides at what level to acquire it. The period is kept quick since the cells start to Recuperate when They can be disconnected with the load.
This examination keeps the ability drawn constant. It simulates serious-earth use and can reveal challenges not observed in continuous present-day exams.
For lead acid batteries, the calculated p.c capacity must be no less than 90% of the rated potential for your battery to move the take a look at. The results obtained from this exam can be used since the baseline for long run measurements.
After the examination current is decided, click here the next step is to find out the potential from the test gear. Discharge check devices or load testers can be found in a variety of sizes and shapes. The large types are capable of drawing superior quantities of present-day and will function for an array of battery programs but aren’t moveable.

If a mistake is built even though commencing the test, the take a look at can not be restarted quickly as the battery discharge data read more may be influenced with the previous attempt. Right planning and planning will be certain there are no hiccups as well as a discharge test may be performed in the ideal fashion and easily.
Frequent discharge testing may help spot batteries which are close to the end of their handy existence, so they are often changed before they fail unexpectedly.
