Batteries, Starting & Charging

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 chargers plus Comfort Connect accessories, indicators and clamps filling this shelf. CTEK is a charger specialist rather than a generalist, and the range shows it: pigtails, panels and plugs that make a stored car easy to keep on maintenance charge. Start with the charger, then add the connector your setup needs.

FAQ

Does this collection sell batteries?

Mostly no. The listings are tie downs, chargers, terminals and a lightweight mount kit, so check your year and model for the hardware and source the battery itself to the size your car specifies.

Will these tie downs fit my Subaru?

Many are titled for all or most Subaru models, and several are listed as universal. Subaru battery placement is consistent across much of the range, but confirm the listing title against your model before ordering.

Why use a smart charger instead of a jump pack?

A smart charger maintains the battery over weeks of storage, while a jump pack only starts the car once. Cars that sit between drives benefit most.

Is a tie down really necessary?

Yes. The battery must be secured: movement strains cables and terminals, and organised track events check for a firm mount. A tie down is one of the cheapest fixes in the engine bay.
