It provides 200 Cold Cranking Amps (CCA) and robust cycle durability, so it works well in vehicles and equipment that need a small, serviceable battery with vibration resistance and broad temperature tolerance.

Will this battery physically fit my Mercedes auxiliary compartment?

Yes — the YTX14-BS uses a compact case and standard terminal layout intended for common auxiliary modules. Check the specific compartment dimensions and terminal orientation before installing to ensure compatibility.

• Battery dimensions: 6.00" x 3.44" x 5.75" (length x width x height).
• Terminal polarity: Positive on the left, Negative on the right when facing the terminals.
• Listing includes the battery and mounting screws only — no harness or extra brackets.

How does this battery perform in cold starts and extreme conditions?

The YTX14-BS is rated at 200 CCA, giving it strong short-burst starting capability for small engines and auxiliary circuits even in lower temperatures. Its AGM-style sealed construction improves discharge rates and helps maintain reliable output across a wide temperature range.

• 200 Cold Cranking Amps for short high-current demands.
• SLA/AGM design resists spills and tolerates broad operating temperatures.
• Engineered to handle shocks and vibration common in automotive use.

How should I charge and maintain this sealed lead-acid battery?

The YTX14-BS is rechargeable and accepts standard SLA/AGM charging profiles; using a compatible charger extends lifecycle and ensures safe operation. Because it is sealed, periodic top-up with water is not needed, but proper charging and storage practices matter for longevity.

• Use an SLA/AGM-compatible charger and follow manufacturer charging voltages.
• Storage at moderate temperatures and a maintained charge preserves capacity.
• Mountable in any position, but secure the battery to minimize vibration stress.

What warranty and expected life should I anticipate?

Mighty Max Battery backs the YTX14-BS with a full one-year warranty, covering defects in materials and workmanship under normal use. Actual service life depends on operating conditions, charge practices, and how often deep discharges occur.

• Full one-year limited warranty from Mighty Max Battery.
• Designed for long service life with deep-discharge recovery capability.
• Durable construction for repeated charge/discharge cycles in vehicle service.
