This is a brand new SigmasTek STX14L-BS battery built for Harley-Davidson Sportster models—specifically the XL and XLH 883cc from 2004 up to 2020.

It’s a 12-volt rechargeable SLA AGM battery, so it’s sealed, maintenance-free, and ready to install.

No filling, no mess, just drop it in and go.

SigmasTek backs it with a 6-month warranty, and it’s built to handle vibration and tough conditions.

Quick heads-up: it has the standard Prop 65 warning about lead, but that’s on pretty much every battery.
