XS Power D5100R
I was looking for an AGM drop-in replacement battery for my ‘13 Civic Si. I ordered the 580 posts with the battery. When I received it, I found that this battery is wider than the OEM battery so the OEM tray cannot be used and the OEM battery hold down is too narrow also. I ordered a K Tuned battery hold down which shoud hopefully solve the width issue. I had to pry up one of the OEM ground cable holders to get some extra slack to reach the ground post. This battery is A LOT more powerful than the OEM unit. The car starts up as soon as the key turned. Eventually, I am going to get a Singer alternator to use to power the system that I am currently piecing together.
