Will this fit my Honeywell / Resideo LTEM-PA?

The CA465 is listed for Honeywell / Resideo LTEM-PA, Honeywell / Resideo LTEM-PV. Match the voltage (4V), capacity (6.5Ah), size (2.72 × 1.81 × 3.94 in) and terminal to your old battery, or use the fit check at the top of this page.

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.
