Aims Power AGM 12V 200Ah Deep Cycle Battery Heavy Duty - AGM12V200A

Aims Power AGM 12V 200Ah Deep Cycle Battery Heavy Duty - AGM12V200A

This 12V AGM battery is a heavy duty, deep cycle battery ideal for back-up power, golf carts and stored power applications. Affordable without compromising quality, this battery will provide power for years. This heavy duty rechargeable battery is made of AGM lead lead dioxide technology. The extra thick lead plates in this battery allow for a deeper discharge with less harm to the battery and provides 20% more charge/discharge cycles compared to other AGM batteries.  AGM batteries have less instant energy, but greater long-term energy delivery.   The dilute sulfuric acid electrolyte is absorbed by separators and plates, thus immobilized. Should the battery be accidentally overcharged producing hydrogen and oxygen, special one-way valves allow the gases to escape, avoiding excessive pressure build-up. Otherwise, the battery is completely sealed and is, therefore, maintenance-free, leak-proof and usable in any position. Perfect for applications requiring large amounts of power and much longer run time.

Starting batteries, such as car batteries should not be used for deep cycle applications because of the thinner plates in these batteries. They are more prone to warping and pitting when discharged.

You can connect these batteries in series or parallel depending on DC voltage needed. Most common voltages are 12, 24, 36 and 48V.

Maintenance Tips  

• Store and operate in a cool, dry environment (ideally 20–25°C) to reduce capacity loss and extend service life.
• Keep batteries fully charged whenever possible; avoid long periods in a discharged or partially charged state.
• Inspect terminals, bolts, and cable connections regularly; tighten and clean any corrosion to maintain low resistance.
• Use a proper AGM-compatible charger (14.4–14.7V bulk/absorption range) to prevent undercharging or overcharging.
• Limit continuous discharge depth (recommended ~50% DoD) to significantly improve cycle life.
• Ensure proper ventilation in enclosed battery banks to prevent heat buildup during heavy load or charging.
• Check for swelling, leakage, or case deformation—replace immediately if any physical damage appears.
• Avoid exposing the battery to extreme temperatures below -20°C or above 60°C during operation or storage.
• Keep batteries clean and dry; dust or moisture on the case can lead to self-discharge paths.
• Use identical batteries (same age, capacity, and type) when connecting in series or parallel for balanced performance.
• Periodically test resting voltage (healthy fully charged AGM ≈ 12.7–12.9V) to monitor battery health
