Batteries

Product Description:
RES can provide you with your batteries and supplies. From entire battery banks to keep your home running off-grid for extended periods to just a small bank for your RV, cabin or for furnace backup we are your premier source for everything battery related.
We are an authorized dealer and stocks a full selection of Rolls Surrette, Trojan, Discover Energy Systems, and Sun Xtender Deep-Cell AGM batteries. Stop in and see our extensive inventory of deep-cycle, lead-acid, and AGM batteries. Tools and tips for maintaining your batteries and maximizing their output and life are available in our store.
We also carry Lithium Batteries with a drastically longer cycle life over a lead-acid, 4-5x service life over lead-acid. This means you would get 5-7 years out of a lead-acid battery but would get 20 yrs out of lithium (keeping all other factors equal). Improved charge technology, halve your generator run time, reap the fuel savings! No maintenance, no fluids, no worries. Incredible energy density in a lightweight package.
Product Specifications:
- Energy Type: Battery Backup
- Suitable for: Commercial, Residential
- Specialties: Marine, RV
Have questions?
Does RES design backup power for clinics and schools?
RES works with residential, commercial, and remote applications and can evaluate storage, generator integration, electrical infrastructure, controls, and ongoing support as one system.
How does cold weather affect where batteries are installed?
Alaska temperatures affect battery performance and charging, so siting, enclosures, and heating are part of the design.
Why combine batteries with a generator instead of choosing one?
Batteries carry loads instantly and silently, while a generator extends runtime when the outage outlasts stored energy.
Can a battery system keep a facility running through a multi-day winter outage?
Runtime depends on the critical-load profile, battery capacity, and whether a generator or solar recharges the system. RES designs to a runtime target agreed with the facility.
How does a business decide which loads a backup system should carry?
RES starts with an energy audit and load calculations to separate critical loads (refrigeration, servers, medical or process equipment, life-safety lighting) from loads that can wait. The critical-load list drives battery capacity, generator size, and the electrical integration design.
How do we begin planning a commercial renewable energy project?
Contact RES with your project location, facility type, current energy sources, approximate energy requirements, and operational goals.
Does RES offer commercial system maintenance and support?
Yes. RES provides operations and maintenance services, including monitoring, preventative maintenance, battery testing, troubleshooting, repairs, and system upgrades.
Can renewable energy reduce operating costs for an Alaska business?
Renewable energy may help reduce electricity purchases, fuel consumption, or exposure to changing energy costs. Actual financial benefits depend on system design, energy demand, utility rates, fuel costs, project location, and installation expenses.
Does RES work on commercial energy projects in remote Alaska?
Yes. RES serves customers across Alaska, including rural and remote locations.
Can RES integrate renewable energy with existing generators or electrical systems?
Yes. RES designs hybrid power systems that can combine renewable generation, battery storage, generators, and existing electrical infrastructure.
