Battery alarm when using winch

I have a Smitty XRC 9.500lb winch on my 2003 Sport. I was just testing it out and had it on flat ground hooked to a tree about 75 feet away. I pulled the Jeep to the tree but the battery alarm went off three times. I had it started and In neutral. I waited each time until the gauge showed the battery recovered about a minute or so for this. I kept the engine running the whole time. Is this normal? If it is not normal do I need a new battery? If so what is a good brand to buy and how many crank amps should I get?

Many folks install a hand throttle to keep RPMs up when winching.

Winch uses a HUGE amount of power. It far out uses the available battery very quickly The alternator can only recover at higher RPM

Adding a winch will expose a weak battery very quickly.
A good AGM is the best bet if you can afford it.
