Tech Tip: Easy Side Mount Installations
This battery is supplied with unique terminal hardware (2 spacers and 2 bolts for cable to terminal connection). This hardware is required for proper installation on certain applications. Other hardware may damage terminals and should not be used. The spacers are required for side mount cable installation only! The top mount position does not require the round spacers, use supplied bolts only. Torque bolts to 6 to 8 ft. lbs.
How A Side Mount Looks when Installed:
This is a great battery for the price. Will still crank strong in sub zero temps. I’d take this over the supposedly wonderful fancy factory installed glass-mat battery that failed me in just over a years time.
Bought the Mega Crank for my 2005 Fatboy (which was about $85 below Harley and the same CCA) and from the first hit till now it’s been perfect! Why pay more and why buy anywhere else??
This battery fires my Harley right up great cold cranking amps. So far so good and reasonably priced,
Could not be more pleased and satisfied with my recent purchase of the MTX20L, as a replacement battery for my Goldwing GL1800. Delivers the cold cranking amps my Wing needs for sure starting time after time. Thanks Battery Mart! Highly recommend this battery as a replacement for your GL1800, you won't regret it.
Shipment was fast. Only a few weeks old, but so far battery is doing great. Really cranks my Harley Low Rider quick! And it was the perfect size for the battery box. I just love it when you buy something and there are absolutely no issues! Thanks Battery Mart!
Good battery for the price. Turns my 103ci Switchback over good. Word of advice...They say the battery comes fully charged, not quite. It comes almost fully charged. I put mine on the charger to fully charge it before installing. This way the battery won't get a memory of an almost full charge. Just got it so I can't say anything about longevity.
Got 5 years out of last one. We will see if this stands the test of time.
