Last updated Aug 17, 2026

Choosing a replacement battery for your motorcycle or ATV often comes down to finding one that delivers reliable starting power without complicating your routine. Sealed AGM options simplify things by removing the need for maintenance, but you still want a battery that fits the YTX7L-BS spec and provides enough cold cranking amps for your machine.

Quick Verdict

The Mighty Max YTX7L-BS is a 12V, 6Ah sealed AGM battery that lists at $24.99. It comes already charged, sealed, and maintenance free, with 100 CCA, a 5.51 lb weight, and a 1-year warranty. For riders who need the YTX7L-BS form factor and prefer a no-maintenance powersports battery, this is a straightforward option to consider.

This battery is built for the YTX7L-BS size class, which appears in motorcycles, ATVs, personal watercraft, jet skis, and snowmobiles. The absorbed glass mat construction is designed to be spill-proof and vibration-resistant, which suits the demands of recreational powersports. The battery arrives already charged, so the packaging is ready to move into service once you confirm the fit.

Who It Suits

A YTX7L-BS replacement like this one is aimed at riders and owners who want a sealed, ready-to-install battery. The dimensions-4.40 inches long, 5.19 inches tall, and 2.75 inches wide-help confirm the footprint for your vehicle. The 5.51 lb weight keeps handling easy, and the 1-year warranty offers basic protection.

What Stands Out

The low-maintenance design is the main appeal. Because it is sealed, there is no need to check or refill electrolyte. The AGM chemistry also holds up well to vibration, which is a real consideration when a battery is mounted on a bike or ATV. The terminal polarity is labeled - I +, which helps avoid connection errors during installation.

Trade-Offs

The 100 CCA rating is a spec to compare with your vehicle's cranking needs. For smaller engines and typical recreational use, that should be adequate; heavier machines may demand more. Also, this is a YTX7L-BS, so it is not a universal replacement. You should verify that your vehicle calls for this exact size and terminal layout. At $24.99, the price is modest, but there is no mention of a longer warranty or any extra accessories beyond the battery itself.

Bottom Line

If your motorcycle, ATV, watercraft, or snowmobile is designed for a YTX7L-BS battery, the Mighty Max YTX7L-BS offers a sealed, maintenance-free AGM solution at a straightforward price. It does not add extra capacity, but for standard applications, the 6Ah rating and 100 CCA should handle the job. Confirm the size and terminal arrangement before ordering, and it becomes a practical pickup for your next battery replacement.
