Yuasa YTX5L-BS Maintenance Free AGM Battery

SKU: ysaYUAM32X5B | Part Number: YUAM32X5B | Type: AGM | Voltage: 12V Small battery, wide application list. The YTX5L-BS is the OEM-spec AGM battery for a huge range of smaller-displacement motorcycles, ATVs, dirt bikes, and scooters — everything from youth quads to enduro machines that need a compact, reliable battery that starts clean and stays out of the way. This version ships dry with the acid bottle included. Fill it at install time, give it an initial charge, and it's done. No water checks, no acid level monitoring, no ongoing fuss.

Key Benefit

The AGM construction is what makes this a genuine upgrade over older flooded-cell designs. The electrolyte is fully absorbed into fiberglass mat separators — the battery is sealed, spill-proof, and can be mounted in any orientation without issue. There's no free liquid inside, which also means vibration resistance is significantly better than a conventional battery. On dirt bikes and ATVs that take real hits, that matters. Lead-calcium alloy holds specific gravity more than three times longer than conventional lead-antimony batteries. In practical terms, that means the battery sits in storage over winter without losing charge nearly as fast. A smart charger once a month keeps it in shape. Come spring, it cranks. At 80 cold cranking amps, this battery is sized correctly for the engines it was designed for — small to mid-displacement motors that don't need the brute starting power of a large cruiser battery, but still need something dependable at 35 degrees on a cold morning trail ride.

Installation

This battery ships dry. At install time, fill slowly with the included acid pack, let it stand for 30 minutes, then charge at 0.5A before fitting to the bike. The initial charge is not optional — it conditions the plates and directly impacts service life. A standard battery tender or smart charger handles the job fine. Maximum charge rate is 0.5A. Don't use a high-output charger on this battery — it's a compact unit and needs to be charged at the correct rate. Once installed and sealed, no further acid or water additions are needed at any point. During periods of non-use, keep it connected to a maintenance charger. Even a good AGM will sulfate and lose capacity if left sitting discharged for months.

Who This Is For

Riders with smaller-displacement dirt bikes, youth ATVs, trail bikes, or scooters that need a clean OEM-spec replacement without the hassle of a flooded battery. If your machine came with the YTX5L-BS from the factory, this is the correct replacement. Yuasa is the original equipment supplier for most major powersports brands — the quality is consistent, the fitment is exact, and there's no guessing involved.

FAQs

Does this come with acid or do I need to buy it separately?
The acid pack is included. Fill at install time, charge, seal — everything needed is in the box.
Do I need to charge it before installing?
Yes. Fill with the included acid pack, let it rest for 30 minutes, then charge at 0.5A before installing. This initial charge conditions the plates and significantly extends battery life.
What's the correct charge rate for this battery?
0.5A maximum. Use a smart charger or battery tender. Do not use a high-output charger — the YTX5L-BS is a compact 4Ah battery and needs to be charged at a low, controlled rate.
Which side is the positive terminal on?
Positive terminal is on the right. Confirm this matches your machine's battery tray before ordering.
Can I mount this battery at an angle?
Yes. The sealed AGM construction means there's no free liquid inside. It can be mounted upright or at an angle without any risk of leakage.
How do I store it over winter?
Keep it connected to a maintenance charger or battery tender set to AGM mode. Check it monthly. A fully discharged AGM left unattended all winter will sulfate and likely won't recover — a basic trickle charger prevents that entirely.
Is this battery the same as what came from the factory?
Yuasa is the OEM battery supplier for most major motorcycle and powersports manufacturers. If your machine originally shipped with a YTX5L-BS, this is the exact same specification — same construction, same quality, same part number.
