Daakmax 12V 20Ah YTX20HL-BS Motorcycle/ATV Battery — 310 CCA AGM, Sealed Maintenance-Free

Daakmax YTX20HL-BS is a 12V, 20Ah sealed AGM motorcycle battery that delivers strong cold-start power, maintenance-free operation, and multi-position mounting for motorcycles, ATVs, UTVs and snowmobiles.

Built to replace common YTX20HL-BS and equivalent part numbers, this compact battery combines an Absorbed Glass Mat design with a sealed casing to minimize leakage and reduce maintenance. With a rated 310 CCA it’s made to crank reliably in cooler conditions, while ISO9001/CE/UL certifications reflect consistent manufacturing and safety standards. The terminal layout, size, and rugged construction make it a drop-in substitute for many Harley-Davidson, Honda and powersports applications.

How does the Daakmax YTX20HL-BS perform on cold starts?

This battery is specified at 310 cold cranking amps, giving it the burst of current needed to turn over engines in lower temperatures. Its AGM internal structure helps deliver high instantaneous current while maintaining a stable voltage under load.

• 310 CCA rating for dependable starting power
• AGM design supports strong discharge and recovery
• Sealed housing avoids acid leaks and improves safety

Is it easy to install and which models will it replace?

Daakmax YTX20HL-BS follows common motorcycle battery dimensions and terminal orientation (left negative, right positive), allowing straightforward replacement without modifications. It replaces many OEM and aftermarket references including YTX20HL-BS, ETX20L, 20HL-BS and Yuasa equivalents, making it suitable for a broad range of bikes and utility vehicles.

• Dimensions: 6.88 x 3.42 x 6.1 inches for direct-fit swaps
• Left negative (-) and right positive (+) terminal layout
• Cross-references common part numbers for easier sourcing

What advantages does sealed AGM technology provide?

The Absorbed Glass Mat construction immobilizes the electrolyte inside a fibrous mat, which reduces the risk of spills and allows safe operation in multiple orientations. AGM also tends to be more resistant to vibration and shock than conventional wet-cell batteries—important for powersports and on-road use.

• Maintenance-free, no topping up of fluid required
• Mountable in various positions without leaking
• Improved vibration resistance for rugged riding conditions

How long can I expect reliable service and what care does it need?

Performance life depends on use, charging habits, and environment, but routine checks and correct charging will prolong service. The manufacturer recommends replacing the battery about every two years for optimum reliability in demanding applications; storing on a smart maintainer when idle helps preserve capacity.

• Recommended replacement cycle: about every two years for peak reliability
• Use a compatible charger or maintenance trickle charger during storage
• Keep terminals clean and connections tight to prevent voltage drop

Who is this for? Riders and owners who need a dependable, maintenance-free power source for motorcycles, ATVs, UTVs, and snowmobiles will find the Daakmax YTX20HL-BS a practical choice. It’s aimed at people who value straightforward installation, strong cold-start ability, and a sealed AGM design that tolerates vibration and various mounting orientations. Whether replacing an aging battery or stocking a spare for seasonal vehicles, this battery offers a compact, high-CCA option with broad compatibility and recognized safety certifications.
