Zetor 3340 Extra Battery Notes
Bad battery symptoms
Common Zetor battery problems show up as hard starting or the tractor not cranking at all, and sometimes you may hear a clicking sound when you try to start it. Another sign is a rapid drain where the battery won’t hold a charge and goes flat quickly, even after being parked for a short time.
Basic battery safety
Disconnect the negative cable first, then disconnect the positive cable. Install the new battery, connect the positive cable first, then reconnect the negative cable last. That reduces the chance of shorting a tool against the frame.
Official information note
Mistakes do happen. Battery specs can change by year, engine, market, terminal layout and installed options. Check the old battery label, operator manual, parts book and official zetor.com website before ordering a replacement battery.
