Yuasa YTX5L-BS 12V AGM Motorcycle Battery (YUA M32X5B) — 80 CCA, 4 Ah, Maintenance-Free, Ship-Dry

Yuasa YUAM32X5B (YTX5L-BS) is a maintenance-free AGM 12V battery supplied dry and activated by the user for reliable starting power and spill-proof operation.

If you need a compact, service-friendly battery for motorcycles, scooters, ATVs or small powersports machines, this Yuasa YTX5L-BS delivers a balance of cold-cranking ability, predictable capacity and easy transport. The battery uses Absorbed Glass Mat (AGM) separators and lead-calcium plates so it holds charge longer than older lead-antimony designs, and because it ships bottle-supplied (dry) the electrolyte is added on activation to meet shipping and storage regulations.

How does this battery perform in cold starts?

The YTX5L-BS offers 80 cold cranking amps (CCA) at 0 °F (-18 °C), which is well-suited for many small-displacement engines. CCA measures the battery’s ability to start an engine in low temperatures; higher CCA helps ensure reliable ignition on chilly mornings.

• 80 CCA rating for dependable starting in cold conditions
• AGM construction supports quick current delivery to the starter
• Best for 50–250cc engines and other low-capacity applications

What maintenance does the YTX5L-BS require?

This is a maintenance-free, valve-regulated AGM unit once activated — there’s no need to add water. However, like all lead‑acid batteries, it benefits from periodic charging if stored long-term to avoid deep discharge and capacity loss.

• Ship-dry with a separate acid bottle; user fills and activates the battery
• No watering or electrolyte topping after activation
• Recommend charging every few months when not in use to preserve life

Will this battery fit my bike and how big is it?

The YUAM32X5B / YTX5L-BS is a compact battery designed for small powersports machines. Check your owner’s manual or existing battery group size to confirm compatibility; the dimensions and weight are provided to help match mounts and trays.

• Dimensions: 4 1/2 in (114 mm) L × 2 13/16 in (71 mm) W × 5 3/16 in (106 mm) H
• Weight (filled): 4.2 lbs — easy to handle and install
• Common replacement for many motorcycles, scooters and ATVs using the YTX5L-BS group

How long will the battery hold charge and what are charging specs?

Yuasa’s lead‑calcium technology slows self-discharge so the battery retains specific gravity longer than older antimony types. It has a rated capacity of 4 Ah at the 10-hour rate and a recommended regular charge current of about 0.5 A for routine charging.

• Capacity: 4 Ah @ 10HR for starter and accessory loads
• Regular charge current: ~0.5 A recommended for safe charging
• AGM design reduces water loss and enables safe valve-regulated charging

Who this battery is for: Riders and owners who need a compact, service-friendly battery that ships dry for safe transport and becomes a maintenance-free AGM after activation. It’s ideal for small motorcycles, scooters, dirt bikes and some ATVs where 80 CCA and a 4 Ah capacity meet starting and accessory needs. Choose the YUAM32X5B if you want a robust, spill-proof option with reduced self-discharge compared with older lead‑antimony batteries.
