ExpertPower YTX5L-BS 12V 5Ah Motorcycle Battery — AGM Sealed, 125 CCA, Maintenance-Free

This compact, valve-regulated sealed lead-acid (SLA) battery is engineered to replace OEM units in small motorcycles, scooters, ATVs and utility machines. Its absorbed glass mat (AGM) construction keeps electrolyte immobilized, so there’s no topping up and minimal self-discharge. The unit ships charged and ready to install; simply confirm physical dimensions and terminal orientation before fitting.

Will this battery fit my bike or ATV?

Fitment requires matching size, terminal orientation and capacity to your original battery. The YTX5L-BS measures 4.45" long x 2.76" wide x 4.21" high and uses a negative-to-positive terminal layout, which corresponds to many small-displacement motorcycles and youth ATVs.

• Dimensions: 4.45" L x 2.76" W x 4.21" H
• Weight: approx. 3.62 lbs
• Terminal order: negative (-) then positive (+)
• Common fits: Skyhawk 90/50, FX Zuma, YFM90, and similar models

How does AGM technology improve reliability?

AGM batteries use glass fiber mats to hold the electrolyte, which prevents spills and reduces internal resistance. That construction improves vibration resistance and allows the battery to withstand the jarring conditions common in off-road and powersports use.

• Sealed, leak-proof design for safe mounting in varied positions
• Lower self-discharge than conventional flooded cells
• Better tolerance for vibration and shocks
• Maintenance-free: no need to add water

What kind of starting and temperature performance can I expect?

This battery delivers 125 cold cranking amps (CCA) at 25°C and a reduced 62 CCA at -18°C, suitable for small engines and scooters. It’s specified to operate across a broad temperature span so it remains usable in most seasonal conditions, though extreme cold will lower starting power.

• Rated 125 CCA at 25°C (77°F)
• Rated 62 CCA at -18°C (0°F)
• Operating temperature range: -30°C to 55°C
• Designed for frequent vibration and stop-start use

How easy is it to install and maintain?

The YTX5L-BS ships charged and is ready for immediate installation — a true plug-and-play replacement for matching OEM batteries. Maintenance demands are minimal because the sealed AGM construction prevents spills and eliminates the need for periodic electrolyte checks.

• Arrives factory-charged for immediate use
• Sealed, no watering or acid handling required
• Store on a charger or float charger for long-term storage
• Confirm polarity and fit before tightening terminals

Who is this for? The ExpertPower YTX5L-BS fits riders, parents of youth-ATV riders, utility vehicle owners and mechanics who need an inexpensive, maintenance-free OEM replacement battery for small-displacement motorcycles, scooters and quads. Choose this model if you want a sealed, vibration-resistant battery that arrives ready to install and matches common YTX5L-BS OEM specifications. If you’re unsure about fit, compare the physical dimensions, terminal orientation and CCA ratings to your original battery before ordering.
