Mighty Max Y50-N18L-A3 12V 350 CCA Battery
The Y50-N18L-A3 is a 12V, 21 AH sealed lead-acid (SLA) AGM battery with 350 CCA. Dimensions are 7.94 x 3.44 x 6.19 inches. Negative on the left, positive on the right. This listing includes the battery and screws only, with no additional mounting hardware. Best for riders needing solid cold-start power in moderate to cold climates. Not ideal if the bike requires extra mounting accessories not included in the package.
Mighty Max YTX24HL-BS 12V 350 CCA
The YTX24HL-BS is a 12V 21 AH SLA/AGM battery with 350 CCA. Dimensions: 8.07 x 3.42 x 6.37 inches. Polarity: Negative on the left, Positive on the right. It is a straightforward replacement for many sport and cruiser bikes, offering reliable starting power and easy mounting. Best for riders who need a compact yet capable battery with robust cold-weather performance. Limitation: only the battery and screws are included; no mounting kit or wiring harness is provided.
Goodyear GYTX24HL 350 CCA
The GYTX24HL is a 12V, 26 AH, 350 CCA maintenance-free SLA/AGM battery designed for motorcycles, ATVs, UTVs, scooters, snowmobiles, and more. It features a sealed design that allows flexible mounting in most positions (excluding upside down). Best for users needing strong ignition power in varied climates and environments. Caution: avoid exposure to prolonged high temperatures if the battery is unvented in non-vented compartments.
Mighty Max YTX24HL-BS GEL 350 CCA
The YTX24HL-BS GEL variant delivers 21 AH with 350 CCA using GEL chemistry. GEL batteries typically offer slower self-discharge and better performance in extreme temperatures, which helps retain charge over longer periods. Best for riders who face long idle times or frequent temperature swings. Limitation: GEL batteries can be less forgiving with fast recharging in some older charging systems; verify compatibility with your charger.
YTX14S Battery (11.2 AH, 230 CCA)
This product is a smaller option at 12V with 11.2 AH and 230 CCA. Best for lighter duty bikes or riders in milder climates where higher CCA isn’t essential. Choose this if your motorcycle battery compartment requires a compact size and the bike’s starting load is lower. Limitation: significantly lower CCA compared to 350 CCA models.
Buying Guide
Key considerations help buyers select the right 350 CCA motorcycle battery for their bike and climate.
What matters most: CCA, AH, and chemistry
- CCA (cold-cranking amps) is critical for cold starts. For riders in cold climates, higher CCA improves starting reliability.
- AH (amp-hour rating) reflects battery capacity and expected runtime. Higher AH means longer life between charges under typical riding conditions.
- Chemistry type affects maintenance needs, self-discharge, and performance in extreme temperatures. AGM and GEL are common maintenance-free options; GEL often offers slower self-discharge and better temperature resilience.
Maintenance-free and installation considerations
- Maintenance-free seals reduce the need for topping up water, but ensure compatibility with your bike’s charging system.
- Check mounting orientation and space in the battery tray. Some models allow multiple mounting positions; others require specific fitment.
Which one to choose: best-for scenarios
- Best for cold starts in variable climates: Mighty Max Y50-N18L-A3 and YTX24HL-BS offer strong CCA with solid AH.
- Better for long idle periods or storage: GEL variants (YTX24HL-BS GEL) reduce self-discharge and maintain charge longer.
- Best value in a compact crate: YTX14S is a smaller option with lower CCA for light-duty bikes.
Installation and compatibility notes
- Always verify the battery dimension, polarity, and terminal layout to match your bike’s battery tray and wiring harness.
- Ensure the battery is charged before installation and dispose of old batteries properly according to local regulations.
FAQ
- Q: Do all 350 CCA batteries fit every motorcycle? A: No. Check dimensions, polarity, and mounting hardware requirements for your model.
- Q: Are GEL batteries better than AGM for motorcycles? A: GEL offers slower self-discharge and temperature stability, but AGM batteries are often more common and cost-effective for many bikes.
- Q: Can I use a 350 CCA battery in a bike that originally used a 300 CCA battery? A: Generally yes if dimensions and polarity match, but confirm with your bike’s specifications and electrical system.
- Q: How should I store a motorcycle battery for winter? A: Store in a cool, dry place and maintain a charge with a smart charger compatible with AGM or GEL chemistry as appropriate.
- Q: What maintenance is required for SLA/AGM batteries? A: Most are maintenance-free, but avoid deep discharges and keep terminals clean and tight.
