AGM battery Safire 12 V 18 Ah BATT-1218

Description of the AGM battery Safire 12 V 18 Ah BATT-1218

The Safire BATT-1218 rechargeable battery uses agm lead-acid chemistry and supplies a nominal voltage of 12 V. Its capacity is 18 Ah, specified at a 20-hour rate, with a T6 connection. The body measures 168 (H) x 181 (W) x 77 (D) mm, making available space and terminals part of the selection. It is intended to power compatible equipment or replace a battery when chemistry, voltage and connection match. It supports standby and cyclic operation, using different voltage ranges. Nominal capacity alone does not determine runtime, which depends on consumption and discharge conditions. The charging system must follow the parameters of this specific reference and the requirements of the connected equipment.

Installation and configuration

Match polarity and use a charger compatible with agm lead-acid. Check the 168 (H) x 181 (W) x 77 (D) mm installation space and T6 connection. Distinguish the standby range 13.5 – 13.8 V from the cyclic range 14.4 – 14.8 V. Set limits according to the battery and equipment documentation.

Frequently asked questions (FAQ)

Does capacity indicate hours of runtime?

Not directly. The 18 Ah rating uses a 20-hour rate. Runtime depends on load and discharge conditions.

Are standby and cyclic voltages the same?

No. Standby: 13.5 – 13.8 V. Cyclic: 14.4 – 14.8 V. Charger settings must match the operating mode.

Is matching voltage enough for replacement?

No. AGM lead-acid chemistry, charging parameters, the T6 connection and available space must be compatible.
