12 V 17 AH 18 AH AGM battery

This sealed lead-acid battery uses absorptive glass mat technology to deliver maintenance-free power. It is built for UPS units, alarm panels and backup systems that require a 12 V 17 AH or 18 AH replacement. The non-spillable design meets IATA requirements for safe transport in any orientation.

100 % OEM replacement and gas recombination

The battery fits existing compartments without modification and recombines over 90 % of gas generated during normal use. A three-year warranty covers UPS and backup devices, while other applications receive a two-year warranty. No water checks or electrolyte top-ups are needed throughout the expected service life.

Check voltage capacity and terminal layout

Verify that your equipment specifies a 12 V input and can accept a 17 AH or 18 AH rating before ordering. Confirm the physical dimensions and terminal positions match the unit being replaced. Ensure the charging system is compatible with sealed AGM chemistry to avoid damage.

Questions about this item

How often will the 12V 17AH 18AH SLA battery need water or electrolyte checks?

The AGM design recombines over 90% of gas internally, so no water top-ups or specific-gravity checks are required during its 4-7 year floating service life.

What capacity limit appears first when the 12V 17AH 18AH battery runs continuously?

The 17AH/18AH rating defines the total energy available; once that ampere-hour reserve is exhausted the voltage drops and the load must be recharged.

Does the 12V 17AH 18AH AGM battery get hot or vent gas during all-day UPS duty?

Sealed construction and 90% gas recombination keep heat and venting minimal; the case is rated non-spillable for safe operation in any orientation.
