Tomioka Racing Batteries (TR) – Lightweight AGM Power for Street, Track & Race

Tomioka Racing TR batteries are lightweight AGM performance batteries built to cut weight and still crank hard. Choose from TR-B600 through TR-B2100, plus bundles with a CTEK charger/maintainer and proper mounting solutions so your setup stays safe for street or tech inspection.

Why Tomioka Racing TR batteries

TR batteries use AGM (Absorbed Glass Mat) technology and are designed to mount vertically or horizontally, giving you flexibility in tight engine bays and race builds.
They ship with brass SAE terminals (with stainless threads) to handle high amperage demands, and they’re sealed/valve-regulated and maintenance-free to reduce spill/corrosion headaches.
Most importantly: the right lightweight battery is a simple way to drop real weight—often 20–30+ lb depending on what your factory battery weighed.

Pick the right TR battery 

Don’t skip the mount

If you’re going smaller than OEM, you need a secure mounting solution. TR’s aluminum mounting kit is 6000-series black anodized aluminum (strong, light, corrosion-resistant) and includes the hardware for an easier install.
Real-world note: improper fitment is exactly how batteries shift in the tray and fail tech—use the right tray/hold-down.

Battery tender bundles

These lightweight batteries can sit for days/weeks in a garage queen or track build. That’s why you’ll see optional CTEK battery tender/maintainer bundles—they help keep the battery topped off and ready.
