Shopping for a replacement 12V battery for an ATV, motorcycle, scooter, or moped usually comes down to two practical choices: a basic sealed lead-acid battery that handles normal starting duties, or a higher-capacity version that offers more cranking strength. Here are two batteries that look similar at first glance but differ in important ways: the Mighty Max YTX4L-BS and the ExpertPower YTX5L-BS.
Quick Verdict
If your main priority is keeping the cost low and your vehicle's electrical demands are modest, the Mighty Max YTX4L-BS at $19.99 provides the core features you need. If you want more reserve capacity and a higher cold-cranking amp rating for stronger starts, the ExpertPower YTX5L-BS at $23.99 is the better match, and it includes nuts and bolts for installation.

Where Each Product Wins
- Mighty Max YTX4L-BS wins on the listed price.
- ExpertPower YTX5L-BS wins on amp-hour capacity, cold-cranking amps, and included installation hardware.
Mighty Max YTX4L-BS
The Mighty Max YTX4L-BS is a sealed lead-acid (SLA/AGM) battery that comes charged, sealed, and maintenance-free from the box. It's rated at 12 volts and 3 amp hours, with a 50-amp cold-cranking rating, and is offered with terminals and a nut for straightforward mounting. It carries a 1-year manufacturer warranty, which is a useful safety net. At $19.99, it's the lower-priced option here, making it a reasonable pick for lighter vehicles such as a small scooter, moped, or jet ski that doesn't demand much starting power. The trade-off is the lower capacity and CCA, so if you often run accessories or ride in cold weather, you may want more reserve strength than this battery provides. It is made in Vietnam and weighs about 2.93 lbs.
ExpertPower YTX5L-BS
The ExpertPower YTX5L-BS is also a sealed lead-acid AGM battery, but it steps up to 5 amp hours and a 125-amp cold-cranking rating. It's designed as a direct replacement for YTX5L-BS, CTX5L-BS, GTX5L-BS, ETX5L-BS, and PTX5L-BS, so it covers a wide range of powersport applications. Nuts and bolts are included, which lets you connect it without hunting for extra hardware. The 4.45 x 2.72 x 4.13-inch dimensions make it a bit taller than the Mighty Max, so check that your battery tray has enough vertical clearance. At $23.99, it costs $4.00 more than the Mighty Max, but you're getting roughly two-thirds more capacity and more than twice the cold-cranking amps. This makes it better suited for ATVs, motorcycles, and larger scooters with stronger starting demands. It also comes from Thailand.
Final Choice by Use Case
Choose the Mighty Max YTX4L-BS when you want the lowest listed price and your vehicle starts easily without heavy accessory loads. It provides the basics for $19.99.
Choose the ExpertPower YTX5L-BS when you need more capacity and cold-cranking power, especially for a larger ATV or motorcycle. The extra $4.00 buys a higher output battery with included hardware.
