Mighty Max Battery YTX7L-BS
Mighty Max Battery YTX7L-BS is a 12V 6Ah sealed lead-acid (SLA) battery with 100 CCA. Dimensions are 4.40″ x 2.75″ x 5.19″. Polarity places the positive terminal on the right and the negative on the left. Listing covers the battery and screws only; no harness or mounting hardware included. This model is best for small-displacement bikes or scooters that require a compact, maintenance-free unit. Choose this if you need a lightweight option for tight spaces, but avoid if you demand a higher CCA for frequent cold starts.
Who it’s best for: Riders with compact bikes, scooters, or projects with limited space who need a reliable 6Ah battery.
Limitation: No wire harness or mounting accessories included, so additional hardware may be required for installation.
Mighty Max Battery YTX14-BS
Mighty Max Battery YTX14-BS is a 12V 12Ah SLA/AGM battery with 200 CCA. Dimensions are 6.00″ x 3.44″ x 5.75″. Polarity is positive on the left and negative on the right. Listing includes the battery and screws only; no harness or mounting accessories. This option is well-suited for mid-size motorcycles that need a stronger cold-start performance and longer life under varied temperatures. Best for riders seeking dependable starts in cooler weather, or those upgrading from smaller 6–7Ah units. Consider this if space allows; if not, the larger footprint may require mounting adjustments.
Who it’s best for: Mid-size bikes or riders in cooler climates who want a robust 12V, 12Ah option.
Limitation: Larger footprint than compact models, which may require additional mounting considerations.
Mighty Max Battery YTX4L-BS
Mighty Max Battery YTX4L-BS is a 12V 3Ah SLA battery with 50 CCA. Dimensions are 4.40″ x 2.90″ x 3.42″. Polarity is negative on the left and positive on the right. This listing covers the battery and screws only. It offers a compact option for very small bikes or scooters where space is at a premium, with the caveat of lower CCA. Best for lightweight applications; better for short commutes where frequent cold starts aren’t needed. Avoid if you regularly ride in very cold climates or require high starting power.
Who it’s best for: Small motorcycles or scooters with tight spaces.
Limitation: Low CCA means less reserve starting power in cold conditions.
Mighty Max Battery YTZ14S
Mighty Max Battery YTZ14S is a 12V 11.2Ah SLA battery with 230 CCA. Dimensions are 6.00″ x 3.44″ x 4.38″. Polarity places the positive on the left and negative on the right. This model is listed as the battery plus screws only. It is well-suited for mid-sized motorcycles requiring a balance of compact size and higher CCA. Choose this if you want strong cold starts without the footprint of a larger 12–14Ah unit. Limitation: not the smallest option for very tight cavities.

Who it’s best for: Riders needing a reliable 10Ah battery with solid 180 CCA for everyday starts.
Buying Guide
What to consider when selecting a 12V motorcycle battery:
- Battery type: Most options here are SLA/AGM. They’re maintenance-free, spill-resistant, and suitable for varying temperatures.
- Capacity and CCA: Higher Ah and CCA provide stronger starts, especially in cold climates. Match the spec to your bike’s requirements and riding environment.
- Size and fit: Check the battery dimensions against your bike’s battery tray and mounting hardware. Some models have compact footprints, others require more space.
- Polarity and terminals: Confirm terminal layout (positive/negative locations) to ensure proper compatibility with your bike’s electrical connections.
- Durability and installation: Consider models designed for shock and vibration resistance if you ride on rough roads or off-road.
- Maintenance and warranty: While AGM/SLA units are maintenance-free, verify any warranty terms and replacement conditions.
Frequently Asked Questions
- Q: How do I know which CCA I need for my motorcycle? A: Check your bike’s owner manual or original battery specifications to match or exceed those CCA values for reliable cold starts.
- Q: Are AGM and SLA batteries the same? A: AGM is a type of SLA battery that uses absorbed glass mat technology for better spill resistance and performance; both are maintenance-free in typical motorcycle use.
- Q: Can I mix brands for replacement? A: Mixing brands is possible, but ensure compatible capacity, CCA, size, and terminal configuration to avoid electrical issues.
- Q: How often should I replace a motorcycle battery? A: With normal use, expect 3–5 years, depending on climate, charging habits, and electrical load. Extreme temperatures can shorten life.
- Q: Do these batteries require a special charger? A: Use a charger suitable for sealed lead-acid (SLA/AGM) batteries and follow manufacturer guidance for charging voltages and durations.
- Q: What installation notes matter most? A: Verify correct polarity, secure mounting to reduce vibration, and ensure clean terminals for solid connections.
