Reliable Power for Everyday Riding

The Casil YTX5L-BS is a maintenance-free, 12-volt 4Ah AGM sealed battery designed to replace a broad range of CT5L-BS variants. Its compact form and solid cranking power make it a practical upgrade for bikes, ATVs, and scooters that demand dependable starts across seasons.

Key Specs at a Glance

  • 12V, 4Ah capacity for steady starting power
  • AGM gel sealed, maintenance-free design with spill-proof construction
  • Dimensions: 4.49 x 2.76 x 4.21 inches
  • Direct replacement for multiple CT5L-BS family models and cross-referenced numbers

Broad Compatibility

Why the AGM Advantage Matters

The SLA/AGM design delivers a high discharge rate, a wide operating temperature range, and a long service life with deep-discharge recovery. These traits help maintain reliable starts in hot sun, wet roads, or chilly mornings, while reducing the need for frequent maintenance.
