SW ENERGY BATTERY
powered by EASTPENN.

SW Energy Batteries are built for Newfoundland—where cold winters, salt air, and remote logistics punish average battery choices. That’s why we partner with East Penn: proven battery technology, consistent manufacturing quality, and the durability needed for real-world off-grid, backup, and coastal applications.

But the difference isn’t just the brand—it’s the right battery for the right job. SW Energy carefully selects East Penn battery models based on Newfoundland-specific conditions and use-cases: off-grid cabins, seasonal properties, standby power, marine/coastal installs, and high-cycle systems. The result is better performance, longer service life, and fewer costly surprises.

As a local SW Energy dealer in Newfoundland, you get support you can actually reach. Customers benefit from direct access to manufacturer-level guidance through our network, faster troubleshooting, and professional warranty support—without the runaround.

We also make it easy to do it right the first time. SW Energy will professionally size the right battery for your system at no additional cost, so you get the best value—not just the lowest upfront price.

And with SW Energy’s specialized shipping solutions, professional-grade batteries are easier than ever to get anywhere in the province—delivered safely, reliably, and matched to your needs.
