Circuit required to check the 12 V , 60 Amps battery on load i.e. Load Tester (meter) circuitry is required ?

thanks
 

60 Ampere hours is the batteries capacity. To test it you must simulate the sort of service you would expect in actual use. For instance if it for a car, it must be able to supply, 200A for 30 Seconds with a terminal voltage greater then 10.8V. Or if its for a UPS, then perhaps it should supply 2A for greater then 24 Hours with a terminal voltage greater then 11.5V

For a car ....... What should be the circuit & what components required & their schematic ??

thanks

would this circuit is able to load test a battery either for car engine cranking (12V & 60 Amps) or for UPS battery ?

thanks
 

The tester is meant up to 200A. The author says :
the shunt, yielded currents of 250 amp and 150 amp from a 12 volt battery. (I have not applied this to any 6 volt batteries yet, but it should work ok I think - after testing several batteries of different types and sizes you should get a "feel" for the battery tester. As it has only 2 current settings, by extending or reducing the time (to 20 seconds or 10 seconds) a more complete range of batteries can be catered for.)

250 Amps is huge quantity of current, needs skill to handle. And this is a best example, I do not think any other example is needed. If you study the article carefully, all your answers are in there.
