High setting on your multimeter may be 10 amp. A lead acid battery goes through three life phases. Set your multimeter to 10a and connect it in series with charger and battery.
battery acid drawing
Heres what happens when you turn on a load headlight starter etc.
Battery acid drawing. In the formatting phase the plates are in a sponge like condition surrounded by liquid electrolyte. For example if you draw at 1c on a lead acid battery you will only get half of the capacity that you would have if you had drawn at 005c. Most new batteries are maintenance free so you cant mess with the components inside. The electrolyte sulfuric acid and water contains charged ions of sulfate and hydrogen.
This is called the peukart effect. Also do not interfere with lead acid battery insides. How to fix battery drain in your car diy with scotty kilmer. Charge efficiency of the lead acid battery.
Lead acid battery charger circuit diagram. The sulfate ions move to the negative plates and give up their negative charge. How to test battery. How to find battery drain.
Sometimes there are 2 sockets a high range and a low range. The output of regulated voltage and current is controlled by the transistor q1. Older battery designs lose water in the electrolytea mixture of about one part sulfuric acid and two parts waterfrom evaporation. Test on the 10 amp setting first then if the current drawn is less than your multimeter low setting move to that setting and keep testing.
Testing your battery for parasitic load. A requirement that is all too often neglected. Watering is the single most important step in maintaining a flooded lead acid battery. Always test on the highest setting first.
The sulfate ions are negatively charged and the hydrogen ions have a positive charge. This is a big effect in alkaline carbon zinc zinc air and lead acid batteries. It is a small effect in nicad lithium ion lithium polymer and nimh batteries. How to use a multimeter.
How to calculate battery amp hours. You dont want to risk your future with lead poisoning it can happen easier than. At the right temperature and with sufficient charge current lead acid provides high charge efficiency. How to do a parasitic draw test.
Now you will need to connect your multimeter to show you how much battery is drawing. Exercising the plates allows the absorption of electrolyte much like squeezing and releasing a hardened sponge. The vout of the lm317 is given to the battery which is to be charged pin1adjustment pin of the lm317 is connected to the transistor q1 resistor r1 r2 r5 which will help to adjust the regulator. They are truly disposable after failure.
