A battery tester is basically a voltmeter used while a resistor is draining the battery -
For a car battery try an auto store
for household batteries try Radio-Shack or make your own.
Voltmeter or multimeter.

truck battery Check the specifications on the winch to find its voltage and amperage.
No, a battery is not necessarily dead if it bounces. The bounce test is not a reliable way to determine if a battery is dead or not. It is best to use a battery tester or multimeter to check the voltage of the battery.

The measured voltage of a battery may not match the stated voltage due to internal resistance, temperature, or the age and condition of the battery. These factors can lead to voltage drops when the battery is in use.
A battery float charger is intended only to keep a fully charged battery from losing its charge. It will NOT work to charge a battery that is discharged or damaged. Check the voltage of the battery to be charged. Do not use charger if the battery voltage is less than 9.6 volts.
You need to do a parasitic draw test. Use a voltmeter to check base voltage of battery. Then crank the engine, check voltage at battery. It needs to be at least two more volts than previous base voltage. Then apply a load or turn on headlights. The voltage should not drop over one volt. Ideal base voltage at battery terminals is 12.6, ideal charging voltage would be 14.6, ideal loaded voltage would be 13.6 volts aproximately. If you find a drainage in system and you have a good battery, then you need to check radio and main accessories first, then check door latch switches and courtesy dome lamps.
