Batteries, Starting & Charging

About

The best battery parts here split into two jobs: holding the battery down properly and keeping it charged. For the first, start with the GrimmSpeed Lightweight Battery Tie Down , titled for all Subaru models, or the Perrin and COBB tie downs listed below. For the second, the CTEK MXS 5.0 12V Automatic Battery Charger anchors a deep charger shelf. This 63-product collection is mostly tie downs, chargers and terminals rather than batteries themselves. A loose battery moves under cornering and braking, stresses its cables and can fail tech inspection at track events, so a solid tie down is cheap insurance and an engine bay tidy-up. Charging matters just as much on cars that sit: a smart charger maintains voltage between drives instead of letting the battery drain flat. Round out the bay with Engine Dressing , and read a guide to Subaru engine modifications for the wider picture. Brands to know GrimmSpeed leads the tie down shelf with its lightweight tie down for all Subaru models, plus a lightweight battery mount kit titled for 2008-2021 WRX/STI in this collection. GrimmSpeed is a Subaru specialist in this store, carried for engine and bay hardware designed around these cars. Its battery parts suit owners pairing a smaller or relocated battery with a tidy, secure mount. Perrin is the colour shelf here: its Stiffi and standard tie downs come in red, black, blue, neon yellow and hyper pink, mostly titled for Subaru models or universal fit. Perrin is carried store-wide for Subaru parts with an OEM-plus finish. Choose it when the tie down is as much a bay accent as a hold-down. COBB Tuning offers its tie down in black, titled for a wide Subaru span: 2002-2026 WRX, 2004-2021 STI, BRZ, FR-S/GT86, GR86, Forester XT, Legacy GT and Outback XT/Wilderness as listed. COBB is the tuning-ecosystem name in this store, known for the Accessport and its hardware. Its tie down is the understated pick for a COBB-built bay. CTEK owns the charging side, with the MXS 5.0 and Multi US 7002 ch
