Crown 12CRV110 110Ah 12VDC Maintenance Free AGM Battery

Frequently Asked Questions

What is the Crown 12CRV110 battery?
The Crown 12CRV110 is a 12VDC sealed AGM deep cycle battery with a rated capacity of 110Ah at the 20-hour rate. It is designed for repeated charging and discharging in applications such as solar energy storage, backup power, RVs, marine systems, and remote power equipment.

What makes the Crown 12CRV110 different from a flooded lead acid battery?
The Crown 12CRV110 uses AGM technology, which holds the electrolyte within an absorbed glass mat. Unlike a flooded battery, it does not require routine watering, making it more convenient for installations where regular battery service is difficult.

How much energy is stored in the Crown 12CRV110?
The Crown 12CRV110 is rated at 110Ah at the 20-hour rate, equivalent to 1.28 kWh of rated energy at that rate. At the 100-hour rate, Crown lists 121Ah and 1.41 kWh. Actual available energy depends on discharge conditions, temperature, battery condition, and system design.

Is the Crown 12CRV110 suitable for a 12VDC solar system?
Yes. The battery is designed for 12VDC applications and can be used as part of a properly sized solar energy storage system. The battery bank should be matched to the solar array, charge controller, inverter, expected loads, and required backup time.

Can the Crown 12CRV110 be used in a larger battery bank?
Yes. Multiple 12VDC batteries can be connected in series or parallel when supported by the system design:

• Two batteries in series create a nominal 24VDC battery bank.
• Four batteries in series create a nominal 48VDC battery bank.
• Parallel connections increase amp-hour capacity while maintaining the nominal battery-bank voltage.

Batteries used together should be properly matched, and the wiring, protection, charging equipment, and installation should be designed for the complete battery bank.

Charging & Maintenance

What type of charger should be used with the Crown 12CRV110?
Use a charger or solar charge controller that supports AGM lead acid batteries and can be configured according to the manufacturer's charging requirements. The charging profile should be appropriate for AGM technology.

Does the Crown 12CRV110 require watering?
No. The Crown 12CRV110 is a sealed AGM battery and does not require routine electrolyte watering. However, the battery and its connections should still be inspected as part of normal system maintenance.

Can the Crown 12CRV110 remain connected to a solar charger?
Yes, when the solar charge controller is correctly configured for the AGM battery and provides an appropriate charging and maintenance profile. Incorrect settings can lead to undercharging or overcharging, which may shorten battery life.

How can I prevent premature wear on the Crown 12CRV110?
Keep the battery properly charged, avoid prolonged periods of low state of charge, prevent unnecessary deep discharges, and operate it within suitable temperature conditions. Correct cable sizing and secure electrical connections are also important.

What should I check if the Crown 12CRV110 is not reaching full charge?
Check the solar charge controller settings, available solar production, wiring, connections, and system loads. Also confirm that the battery is receiving an AGM-compatible charging profile. If the system checks out but the battery continues to show poor performance, professional battery testing may be needed.

Crown Battery Comparison

How does the Crown 12CRV110 compare with the Crown 12CRV100?
The Crown 12CRV100 and Crown 12CRV110 are both 12VDC sealed AGM deep cycle batteries. The Crown 12CRV110 provides 110Ah at the 20-hour rate compared with 98Ah for the Crown 12CRV100. Both are designed for applications where maintenance-free AGM construction is preferred, but the Crown 12CRV110 provides more rated storage capacity and uses the larger Group 31.

What is the difference between the Crown 12CRV110 and Crown 12CRV80?
The Crown 12CRV80 and Crown 12CRV110 are both 12VDC sealed AGM deep cycle batteries, but the Crown 12CRV110 provides 110Ah at the 20-hour rate compared with 80Ah for the Crown 12CRV80. The Crown 12CRV110 also uses a Group 31 form factor, while the Crown 12CRV80 is a smaller Group 24 battery. The 12CRV110 is better suited when greater capacity per battery is needed and the available installation space can accommodate the larger battery.

Solar Application & Battery Life

What solar applications are a good fit for the Crown 12CRV110?
The Crown 12CRV110 is suitable for off-grid solar storage, backup power, remote energy systems, RVs, marine equipment, and other applications that need a 12VDC deep cycle battery. Its sealed AGM design is useful where reduced maintenance is a priority.

Can the Crown 12CRV110 be used with an inverter?
Yes, provided the inverter is compatible with the battery-bank voltage and the battery bank is sized for the expected load. Inverter power requirements can create high current demand from a 12VDC battery, so cable sizing, battery capacity, and protection should be considered carefully.

How deeply should the Crown 12CRV110 be discharged in a solar system?
Although the battery is designed for deep cycle use, repeatedly discharging it very deeply can increase battery stress and reduce service life. A properly sized solar battery bank should provide enough capacity to meet normal loads without routinely reaching very low states of charge.

Can the Crown 12CRV110 be used in a remote solar installation?
Yes. Its sealed AGM construction is well suited to remote applications where regular watering is inconvenient. The installation should still provide appropriate environmental protection, electrical protection, temperature control, and access for inspection.

What can reduce the service life of the Crown 12CRV110?
Prolonged undercharging, improper charging settings, repeated excessive discharge, high operating temperatures, poor connections, and unsuitable storage conditions can negatively affect battery performance and service life. Proper system sizing and charging practices are important for long-term use.
