LCP500-4B Battery Replacement for Lynx Security Panels - High Capacity

In this review the focus is on the LCP500-4B replacement battery designed for Lynx alarm systems. The bottom line: this 7.2V, 3700mAh Ni-MH pack is for owners of Lynx 5100, 5200, 5210 and Lynx Touch panels who need a higher capacity, direct-fit replacement that uses the same 3-prong connector as the original. It is a straightforward swap intended for users who want longer backup runtime without changing chargers or panel hardware, and the review highlights compatibility, build dimensions, and installation notes so buyers know exactly what to expect.

Key Features

• High capacity: The 3700mAh rating provides noticeably longer backup time compared with lower capacity replacements, which helps keep security panels powered during longer outages.
• Direct compatibility: Designed to match Lynx 5100, 5200, 5210, Lynx Touch 5210, Lynx Touch 7000, Lyric Controller and Lyric Keypad LCP500-L connectors so it installs without modification.
• Standard connector: Uses a 3-prong battery plug identical to the original, reducing the risk of wiring mistakes during replacement.
• Manufacturer tested: The cell pack and assembly are tested to match original battery performance and comply with CE and ROHS standards for basic safety and environmental rules.
• Easy installation: The compact dimensions and matching plug make the physical swap straightforward for a homeowner or technician comfortable with small electronics.

Who It's For

This battery is best for homeowners and small-business owners who already operate Lynx 5100/5200/5210 or Lynx Touch alarm panels and want a like-for-like replacement with higher capacity. It is also suitable for technicians servicing installations that must maintain original connector types and battery dimensions.

It is not for people who need a different voltage chemistry or a custom connector; anyone unsure of their panel model or connector should verify the part number before purchase. Users who need professional installation due to limited DIY experience should seek a qualified installer.
