Newmar Power - 1-2-70A Isolator

Efficient Multi-Battery Charging for Marine Applications

The Newmar Power 1-2-70A Isolator is designed to provide seamless and automatic charging for multiple battery banks in marine and other DC-based applications. This heavy-duty isolator ensures that each battery is charged according to its individual needs, preventing overcharging and battery drain. Whether used with one or two alternators, it optimizes power distribution without the risk of discharging one battery into another.

Built to withstand harsh marine environments, this isolator features a rust-proof anodized aluminum heat sink case that enhances durability and thermal performance. Its compact design makes it easy to install, and the included stainless steel mounting hardware ensures a secure and long-lasting setup.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
