Yes, a "real" load, as Tony says.
"THe only ways to properly test a battery is to load test it. That does not mean testing with a cheap AutoZone tester, You have to apply a load in excess of 200 amps for at least five seconds."
Just as an example, my "real load" tester pulls 385 amperes at 9.6 battery volts vs the 'nice & neat' Harbor Freight/Tool tester's 17 ampreres!!!, or about 20 times too little.
