Interstate DCM0035 35Ah 12V AGM Deep-Cycle Battery Wholesale 78 pcs per pallet

The Interstate DCM0035 35Ah 12V AGM Deep-Cycle Battery is a sealed, maintenance-free 12V deep cycle battery built on VRLA Absorbent Glass Mat (AGM) lead-acid technology. Rated at 35Ah (20-hr rate), it is engineered for applications that demand repeated deep discharges — including solar energy storage, golf carts, RV and marine house loads, and home backup systems — all in a spill-proof, position-flexible package.

Key specifications

• Voltage / Capacity: 12V nominal / 35Ah (20-hr rate to 1.80V/cell)
• Chemistry: AGM VRLA sealed lead-acid — maintenance-free, spill-proof, no venting or watering required
• Operating temperature: -40°F to 140°F (-40°C to 60°C); optimal charge range 32°F–104°F (0°C–50°C)
• Dimensions / Weight / Warranty: 7.68 × 5.12 × 6.46 in. (195 × 130 × 164 mm) / 22.9 lbs. (10.4 kg) / 1-year free replacement limited warranty from date of purchase.
• Self-discharge: Retains 91% capacity at 3 months; 82% at 6 months — suitable for seasonal storage

No maintenance, no spills, more cycles

Flooded lead-acid batteries require regular water top-offs, forced upright installation, and dedicated venting — drawbacks that make them impractical in boats, RVs, and enclosed solar enclosures. The DCM0035's AGM construction eliminates all three: the glass mat absorbs the electrolyte, VRLA sealing prevents spills and overpressurization, and the battery can be mounted in virtually any orientation. With a recommended depth of discharge between 50% and 80%, it sustains more usable cycles over its service life compared to conventional sealed batteries that are routinely discharged below that threshold.

Key Applications

• Solar energy storage: Serves as the house battery in off-grid cabin, van build, or residential solar backup systems paired with a 12V charge controller.
• Golf carts: A well-matched size for small single-cart auxiliary power or replacement service in low-speed electric vehicles requiring reliable deep-cycle capacity.
• RV house loads: Powers lights, fans, and low-draw appliances in motorhomes and travel trailers without the acid-spill risk of flooded alternatives in confined compartments.
• Marine applications: Suitable for trolling motors, fish finders, and onboard electronics on small boats — sealed construction handles the vibration and tilt common in marine environments.
• Home backup and UPS: Provides standby power for inverter-based home battery backup systems and uninterruptible power supplies requiring a dependable 12V 35Ah AGM deep cycle battery.

Sealed design and mounting flexibility

• Position-flexible installation: Can be mounted in any orientation except fully inverted, giving installers freedom in tight or unconventional spaces where an upright battery won't fit.
• VRLA overpressure management: The valve-regulated sealed design automatically manages internal gas buildup, eliminating the need for external battery venting in enclosed cabinets or storage compartments.

Charging and system compatibility

The DCM0035 is compatible with any 12V solar charge controller — PWM or MPPT — configured to an AGM charge profile. Float voltage should be set to 13.5–13.8V; cycle charge voltage to 14.4–15.0V; maximum charge current is 9.9A. Multiple units can be wired in series to build 24V or 48V battery banks, or in parallel to increase total Ah capacity while remaining at 12V. It is also compatible with standard 12V sealed lead acid (SLA) battery chargers that support AGM chemistry settings.

Why choose the Interstate DCM0035?

Interstate has built its reputation on dependable, field-proven battery performance — and the DCM0035 brings that reliability to compact AGM deep-cycle applications where flooded batteries are impractical. Its broad -40°F to 140°F operating range, position-flexible mounting, and low self-discharge rate make it one of the more capable 12V 35Ah options available through A1 SolarStore for buyers who need a true deep-cycle AGM battery that performs in demanding, real-world conditions rather than just in a controlled spec sheet. It is backed by Interstate's 1-year free replacement limited warranty from date of purchase.
