About this item

Product details

Use the battery finder for help selecting the battery you need

Superior starting power, high reserve capacity, and long-lasting life—there’s no match for these AGM Batteries. Advanced AGM technology with dual-purpose design makes it great for quick starts and plenty of competition-quality accessory power for stereo systems, boats & RVs, hydraulic lifts, winches, and on-board electronics. 

The tight-pack plate and separator construction provides added power for resistance against hard-hitting stereo, competitive racing, or off-road wear and tear vibration. Along with a more efficient design, it also has the same case/cover configuration used by original equipment manufacturers for an easier fit into more applications. No elaborate marketing gimmicks or hold-down retrofits. Just decades of experience to provide a better fit, more power and longer life.

To have your battery installed, please call your local Tire & Battery Center to schedule an appointment.

Great customer service

Got a great price and was eager to install it on my Dad's RV. Te very next day it was dead and had O'Reilly check it since they were closer to me. Had a dead cell. Took back and replaced it no questions. Made it super easy. Thanks 🙏 for such great service!

Works Well

We just bought two more for our trolling motor. We previously bought the same battery for our 140 Suzuki outboard and it has held up great for the past year. We haven't had a chance to run the boat much this year but if we have any problems I will come back and update.

Hallett 210 starting battery for mercury 502

Boat meets the CCA for my starting battery on my mercury 502 big block, just installed beginning of 2020 season but I have been able to let it sit for 2 or 3 weeks and it starts right up every time.
