BRIEN on 10/28/2019

Very well satisfied as my '78 Bonnie is posit+ve ground & the terminals need to match orientation. Perfect fit.

oscartuyub on 10/14/2019

I will start by saying that its been 10 months since i bought this battery and i have had no issues with, installation was easier than my older battery mainly because it is a little smaller. Other than that its been turning on my bike to this date and runs all lights hazards and high B, no problem.

JEFFREY on 9/26/2019

Be aware that the terminals on this battery are not threaded. That is reasonable, but the slot in which you would normally slide in a hex or square nut to receive the terminal bolt is too narrow.

WAYNE on 9/5/2019

Excellent battery for the price and a very reliable one never had a problem with them 👍

Don't fix in a sportster 92, it´s tall, you can't put the cover.The description say that fix, but not true.
