How often should it be replaced?
Sealed lead-acid batteries in standby equipment such as alarm panels, fire panels and UPS units are typically replaced every 3–5 years, or sooner if the system reports a low battery or fails its load test. The date code on the label shows when the battery was made.
Can I use a battery with more amp-hours?
Usually, if the voltage, case size and terminals match: more amp-hours means longer runtime. Check that it fits the compartment and that your charger can recharge it in the time your system requires.
