The AIMS Power 12V 200Ah AGM Deep-Cycle Heavy Duty Battery Delivers Long Run Times for Backup Power and Off-Grid Energy

The AIMS Power 12V 200Ah AGM Deep-Cycle Heavy Duty Battery is engineered for applications that need dependable stored energy and long run times. With 200 amp hours and 2.56 kWh of capacity in a single 12 volt battery, it reduces the number of batteries needed for a sizable bank. Advanced Absorbent Glass Mat technology and extra-thick lead plates provide deeper discharge capability and up to 20% more charge and discharge cycles than many standard AGM batteries, according to AIMS Power, all in a sealed, maintenance-free package that mounts in virtually any position.


AIMS Power 12V 200Ah AGM Deep-Cycle Heavy Duty Battery Features

Extended Cycle Performance From Extra-Thick Lead Plates

Thick internal plates allow deeper discharges with less wear, helping the battery deliver more cycles over its life.

Maintenance-Free AGM Design So You Can Install It and Forget It

The AGM design immobilizes the electrolyte, eliminating water maintenance and allowing safe operation in any orientation.

Rugged Construction for Cyclic or Float Use

Computer-designed lead calcium tin alloy grids provide high power density and durability for both cyclic applications and standby float service.

Safe, Sealed, Leak-Proof Construction

Built-in one-way safety valves release gas if the battery is overcharged, preventing excessive pressure while keeping the battery sealed and leak-proof.

Flexible System Integration for 12V Through 48V

Connect batteries in series or parallel to build 12V, 24V, 36V, or 48V systems. Integrated carry handles and copper terminals support safer handling and reliable connections.


Real-World Applications

Home and business backup. Pair with an inverter charger for extended runtime during outages.

Off-grid solar. Store solar energy for nights and cloudy days.

RV and marine house banks. Use where space allows for longer stays away from shore power.

Standby and industrial systems. The float-capable design suits standby power applications.


How It Compares to Common Alternatives

Versus two 100Ah batteries. A single 200Ah battery means fewer interconnections, though each battery is heavier to handle.

Versus flooded lead-acid. AGM requires no watering and will not spill, making it safer for enclosed spaces.

Versus lithium batteries. Lithium is lighter and typically lasts more cycles, while AGM offers a lower upfront cost and broad charger compatibility.


Is This 200Ah AGM Battery the Right Fit

  • Weight. At 138 pounds, this battery requires two people or lifting equipment and a strong mounting location.
  • Size. It measures 20.5" L x 9.25" H (with terminals) x 9.25" W.
  • Charging. Use an AGM charge profile. AIMS Power lists 14.4 to 14.7 volts for cycle use, 13.6 to 13.8 volts for standby, and a 30 amp maximum charging current.
  • Capacity by discharge rate. 200Ah at the 20 hour rate, down to 126Ah at the 1 hour rate.

This may be a good fit if

  • You need large capacity in a single maintenance-free 12 volt battery
  • You are building a backup or off-grid battery bank
  • You have space and support for a heavy battery
  • Your charger supports AGM batteries
