6PH-H-4/3A3600-S-D22 7.2V 3600mAh Ni-MH Replacement Battery - Reliable

Our review of the 6PH-H-4/3A3600-S-D22 replacement battery finds it best suited for homeowners and installers who need a dependable backup cell for ADT and DSC alarm panels. The single biggest reason to consider this pack is its straightforward compatibility with DSC IMPASSA 9057 and ADT SCW9057G-433 systems combined with a high 3600 mAh capacity, which translates into longer standby times than many stock cells. Installation is simple and the included safety protections give confidence for continuous duty in a security role.

Key Features

• 7.2V Nominal Voltage: Matches the expected supply requirement of compatible DSC and ADT alarm panels to maintain correct system operation without voltage-related faults.
• 3600 mAh Capacity: Provides extended runtime compared with lower-capacity cells, helping panels remain powered during longer outages or frequent alarm activity.
• Ni-MH Chemistry: Offers reliable recharge cycles and a balance of energy density and safety for repeated use in security system backups.
• Built-in Protections: Over discharge, over current and short circuit protection help preserve battery life and reduce risk of failure in service.
• Direct Compatibility: Sold as a replacement for 6PH-H-4/3A3600-S-D22 and compatible part numbers used in IMPASSA 9057 and ADT SCW9057G-433 panels, simplifying procurement for technicians.
• Local After-Sale Support: Manufacturer offers a local support team with 24/7 online response promise to address installation or performance questions.

Who It's For

This battery is aimed at property owners, alarm installers and maintenance technicians who operate or service DSC and ADT-branded alarm control panels that accept the 7.2V 6PH-style packs. It is particularly useful where longer backup duration and standard Ni-MH rechargeability are desired.

Those who should look elsewhere include users who require lithium-based high-energy replacements or who cannot access compatible connectors and mounting space in their specific control box. Also choose an original manufacturer pack if explicit OEM labeling is required by warranty or service policy.

Pros & Cons

Pros

• High 3600 mAh capacity delivers longer backup runtime compared with lower-capacity alternatives.
• Comprehensive safety protections reduce chances of over-discharge, over-current events and short circuits.
• Clear compatibility with DSC IMPASSA 9057 and ADT SCW9057G-433 simplifies replacement decisions for service technicians.

Cons

• Ni-MH cells are heavier and have lower energy density than lithium alternatives, so they are not the lightest option.
