AGM Battery Technology for Solar Power Systems
AGM batteries use an absorbent fiberglass separator to retain electrolyte between the battery plates. This sealed design provides an alternative to traditional flooded lead-acid batteries without requiring routine water additions.
The MK Deka deep cycle battery is particularly useful in solar energy storage applications where dependable battery performance, straightforward maintenance, and compatibility with established lead-acid charging equipment are important.
When paired with an appropriately configured solar charge controller or inverter/charger, this battery can store energy produced by solar panels for later use.
Dependable Off Grid and Backup Battery Storage
For off grid solar systems, battery storage helps provide electricity when solar production is unavailable or insufficient. The MK Deka AGM battery can be incorporated into compatible battery banks to support household loads, remote equipment, and other applications requiring stored DC power.
It can also serve in standby power systems where reliable stored energy is needed during utility outages. Proper battery bank sizing, charging configuration, and system protection help ensure dependable performance.
Applications
- Off grid solar battery banks
- Residential solar energy storage
- Renewable energy and hybrid power systems
- Backup power and standby battery systems
- Remote cabins and off grid properties
- Telecommunications and remote monitoring equipment
- Compatible inverter/charger battery banks

Frequently Asked Questions
Is the MK Deka AGM battery suitable for solar power systems?
Yes. This deep cycle AGM battery is suitable for solar energy storage when used with a compatible solar charge controller, inverter/charger, and properly configured battery bank.
What is the difference between AGM and flooded lead-acid batteries?
AGM batteries use absorbent glass mat separators to retain electrolyte inside a sealed, valve-regulated enclosure. Unlike conventional flooded lead-acid batteries, AGM batteries do not require routine watering and offer reduced maintenance.
Does this battery require maintenance?
The battery does not require routine water additions. However, proper charging, periodic terminal inspections, and battery condition monitoring remain important for reliable operation.
Can this battery be used with an inverter?
Yes. The battery can supply DC power to a compatible inverter or inverter/charger. The inverter’s battery voltage requirements, charging profile, and expected current draw must match the battery bank configuration.
Can I connect multiple MK Deka batteries together?
Yes. Compatible batteries may be configured in series or parallel to meet the voltage and capacity requirements of an appropriately designed system. Batteries should be matched according to the manufacturer’s recommendations.
Is this a lithium battery?
No. This is a sealed AGM lead-acid battery, not a lithium-ion or LiFePO4 battery. It requires charging settings appropriate for AGM lead-acid chemistry.
Can I use this battery for an off grid solar system?
Yes. The battery can provide stored energy for an off grid solar system when paired with compatible charging and inverter equipment. The number of batteries needed depends on your energy consumption, desired backup duration, and system design.
What charging settings should I use?
Use the manufacturer’s photovoltaic charging parameters and the correct AGM battery profile for your charging equipment. Temperature compensation and charging limits should follow MK Battery’s published recommendations.
