VINTRONS 7.2V 3700mAh Ni-MH Battery for Honeywell Lynx and Lyric

In this review of the VINTRONS 7.2V 3700mAh Ni-MH battery, the bottom line is simple: this pack is aimed at homeowners and technicians who need a direct replacement for Honeywell alarm and keypad power backups. The reviewer found the battery to be a straightforward, compatible swap for Honeywell 300-03866, LCP500-4B and related modules, delivering predictable backup runtime without fuss. Its main selling point is compatibility and capacity, making it a sensible choice for anyone replacing an aging internal battery in Lynx 5100/5200/5210, Lynx Touch 7000 or Lyric control hardware.

Key Features

• Direct compatibility: Designed to match Honeywell 300-03866 and related parts so installation is typically plug-and-play without modification.
• High capacity: The 3700mAh rating offers longer backup time than many smaller packs, helping systems stay powered during outages.
• 7.2V Ni-MH chemistry: Provides stable voltage and reliable recharge performance for alarm panels and keypads that expect Ni-MH cells.
• Compact size: At about 100.80 x 68.00 x 17.20mm the pack fits inside the original battery compartment for Honeywell Lynx and Lyric units.
• Multiple model fit: Lists compatibility with Lynx 5100, 5200, 5210, Lynx Touch 7000, Lyric Controller and Lyric Keypad LCP500-L, so it covers several common Honeywell devices.

Who It's For

This battery is best for homeowners maintaining an existing Honeywell Lynx or Lyric alarm setup who need a like-for-like replacement to restore backup capability. It is also suitable for security technicians who stock common replacement parts and prefer a single battery that serves several Honeywell models. The focus is compatibility and dependable backup rather than novelty features.

Those who should look elsewhere include users who require a different chemistry such as Li-ion, or custom-sized packs for non-Honeywell equipment. If you need extended runtime well beyond typical alarm backup needs, consider a larger dedicated UPS or auxiliary power solution instead.

Pros & Cons

Pros

• High capacity provides longer backup runtime compared with smaller OEM replacements.
• Plug-and-play compatibility with Honeywell 300-03866, LCP500-4B and OSA214 avoids wiring changes.
• Stable Ni-MH chemistry accepts repeated recharge cycles common in alarm panels.
• Compact dimensions match the original battery compartment for an easy fit.

Cons

• Ni-MH chemistry is heavier and bulkier than modern Li-ion alternatives, so it is not the lightest option.
• Limited to devices that accept 7.2V Ni-MH packs; not a universal solution for non-listed models.
