YTX12-BS vs YTX30L-BS: Which Sealed AGM Motorcycle Battery Should You Pick?

Compare the YTX12-BS and YTX30L-BS sealed AGM motorcycle batteries by BCI group, cold cranking amps, and physical size to choose the right starting battery for your powersports vehicle.

Last updated Aug 17, 2026

Before you bolt in a new motorcycle or ATV battery, the first decision is the BCI group number. This head-to-head pairs a compact YTX12-BS replacement with a much larger YTX30L-BS / ETX30L unit. Both are sealed AGM and maintenance-free, but their case sizes and cold cranking output are not the same. The real question is simple: does your vehicle ask for the smaller YTX12-BS format or the bigger YTX30L-BS format?

Quick Verdict

Use the BCI group number first. If you need a YTX12-BS group battery, the Banshee-branded replacement gives you a 12-volt sealed AGM battery with 235 cold cranking amps and a maintenance-free, spill-proof design. If your vehicle calls for YTX30L-BS or ETX30L, the Anlibatt-listed battery steps up to 400 cold cranking amps, a 30 Ah rating, and a larger case. Match the group number and the rest of the decision follows.

Where Each Battery Wins

The YTX12-BS replacement wins for:

  • Direct YTX12-BS group designation, so it is the match when your vehicle uses that group.
  • A smaller footprint: about 5.98 in L × 3.34 in W × 5.13 in H.
  • A sealed, maintenance-free AGM battery that still supplies 235 CCA.

The YTX30L-BS wins for:

  • The YTX30L-BS / ETX30L group designation and a bigger 400 CCA output.
  • A 30 Ah rating with an ABS case.
  • Clear positioning for motorcycle, ATV, and scooter use.
  • A larger physical size: 6.54 in D × 4.96 in W × 6.89 in H.

Product Notes

Replacement YTX12-BS Performance-Maintenance Free-Sealed AGM Motorcycle Battery

Replacement YTX12-BS Performance-Maintenance Free-Sealed AGM Motorcycle Battery

Need a compact, sealed AGM starting battery? This Banshee listing is the smaller half of the comparison. It is a 12-volt unit with a YTX12-BS group number, 235 cold cranking amps, and a sealed, spill-proof, maintenance-free lead-acid design. The listed dimensions are about 5.98 inches long, 3.34 inches wide, and 5.13 inches high, making it a much smaller package than the YTX30L-BS. The tradeoff is output: it does not match the 400 CCA or 30 Ah rating of the larger Anlibatt battery. Choose it when your machine is set up for the YTX12-BS group and you want the pair's lower listed price.

YTX30L-BS High Performance Maintenance Free Sealed AGM Motorcycle Battery ETX30L

YTX30L-BS High Performance Maintenance Free Sealed AGM Motorcycle Battery ETX30L

This is the bigger, more powerful entry. Sold under both YTX30L-BS and ETX30L labels, the Anlibatt battery is a 12-volt sealed AGM unit with 400 CCA, 30 Ah capacity, and an ABS case. It is positioned for motorcycle, ATV, and scooter duty, and the listed dimensions-6.54 inches deep, 4.96 inches wide, and 6.89 inches high-match the larger YTX30L-BS group. The limitation is the flip side: it is a much larger battery, so it will not slip into a YTX12-BS-sized space. Pick it when your vehicle needs the larger group and the extra cranking amperage.

Final Choice by Use Case

For a YTX12-BS application: choose the Replacement YTX12-BS Performance-Maintenance Free-Sealed AGM Motorcycle Battery. It carries the right group number, a compact case, and 235 CCA.

For a YTX30L-BS or ETX30L application: choose the YTX30L-BS High Performance Maintenance Free Sealed AGM Motorcycle Battery ETX30L. It brings 400 CCA, 30 Ah, and the larger case size that goes with that group.
