Review: Best lithium battery - I have this brand in most of my vehicles and toys. They work fantastic. I do recommend a proper lithium charger for them. I used Noco brand
Review: Bike fires right up - Bought this for my 2000 HD Softail standard with a big bore kit. Bike has always been hard starting and blown a few starters since big bore; put a all balls starter in with a 400 CCA lithium battery 5 years ago which made a difference but was still straining to start. Bought the Antigravity ATX20 HD says 780 CCA but they send you the 900 CCA, fit right in my bike batt read 368 on ohm meter, after charging overnight read over 390. Turned on the gas pulled the choke hit the starter and BAM fired right up no strain no hesitation. Ohm reading 428 running, this bike has never started this easy. after riding fires right up every time. Super happy with this battery hope it last as long as my old lithium.
