Frequently Asked Questions
What does 200Ah mean on an AGM battery?
200Ah stands for 200 amp-hours, meaning the battery can theoretically deliver 200 amps for one hour, or 20 amps for 10 hours, at the rated voltage (typically 12V). In practical terms, a 200Ah AGM battery provides about 2560 watt-hours (12V x 200Ah) of energy storage. However, to prolong battery life, it is recommended not to discharge below 50% depth of discharge (DoD), so usable capacity is around 100Ah (1280Wh) for daily cycling.
How long will a 200Ah AGM battery last?
The lifespan depends on usage and depth of discharge. AGM batteries typically offer 500 to 2000 cycles at 50% DoD. For example, a battery rated for 1000 cycles at 50% DoD could last 3-5 years with daily cycling. If used lightly (shallow discharges), it can last longer. Factors like temperature, charging practices, and maintenance also affect lifespan.
Can I use a 200Ah AGM battery for solar?
Yes, 200Ah AGM batteries are commonly used in solar systems. They are deep-cycle and can handle repeated charging and discharging. However, they require a compatible charge controller (preferably with a profile for AGM) and should not be discharged below 50% to maximize cycle life. For larger solar arrays, multiple batteries can be connected in parallel.
What is the difference between AGM and lithium batteries?
AGM batteries are lead-acid based, heavier, and have lower energy density. They are generally less expensive upfront but have shorter cycle life (500-2000 cycles) and lower usable capacity (50% DoD). Lithium batteries (LiFePO4) are lighter, have higher energy density, longer cycle life (3000-5000+ cycles), and can be discharged to 80-100% DoD. However, lithium batteries cost more initially and require a specific charger.
How do I charge a 200Ah AGM battery?
Use a smart charger or charge controller with an AGM profile. The charging voltage should be around 14.4-14.8V for bulk charging and 13.5-13.8V for float. Avoid overcharging, which can damage the battery. Many solar charge controllers and inverters have preset AGM settings. It is also important to recharge immediately after discharge to prevent sulfation.
