Power Products CA-1550-CML vs. CA-1550-MIL: Which Aircraft Battery Charger/Analyzer is Right for You?
In aviation, battery reliability is more than just convenience—it’s a matter of safety. Aircraft batteries power critical systems such as emergency lighting, communication, and engine starting. To keep these batteries at peak performance, operators and maintenance teams depend on aircraft battery charger/analyzers that not only recharge but also accurately test battery capacity.
Two of the most trusted tools in this category are the Power Products CA-1550-CML and the CA-1550-MIL. Both models are designed to simplify and standardize the charging, discharging, and capacity testing process for Nickel-Cadmium (Ni-Cd) and sealed or vented Lead-Acid aircraft batteries. They provide precise digital monitoring, automatic test functions, and a user-friendly design that requires no special programming.
While these models share the same performance core, they are built with different users in mind. The CA-1550 CML offers flexibility and portability for civil aviation and ground support applications, whereas the CA-1550-MIL is ruggedized to meet stringent military specifications, making it suitable for demanding environments where durability is non-negotiable.
In this blog, we’ll explore the similarities and differences between the CA-1550-CML and CA-1550-MIL so you can make an informed decision on which one best fits your operational needs.

- Suitable for both bench use and field operations
This model is an excellent choice for operators who need a versatile, all-in-one solution for routine battery maintenance and testing.
Overview of the CA-1550-MIL
The CA-1550-MIL shares the same charging and discharging capabilities as the CML but is ruggedized to meet military standards.
Unique Features of the MIL Version:
- Built for Military Applications: Designed to withstand tougher conditions and meet military specifications.
- Enhanced Durability: Suitable for deployment in environments where shock, vibration, and harsh handling are common.
- Compliance: Configured to meet stringent military requirements for aircraft and ground support battery maintenance.
Like the CML, the MIL version supports Ni-Cd and lead-acid aircraft batteries, provides digital monitoring, and enables automatic charge/discharge testing cycles.
Which One Should You Choose?
- Choose the CA-1550-CML if you’re a commercial operator, MRO facility, or general aviation service provider looking for a reliable, portable, and user-friendly charger/analyzer for a wide range of batteries.
- Choose the CA-1550-MIL if your operations demand military-grade durability and compliance with defense standards, especially in field or tactical environments.
Both models deliver accuracy, safety, and convenience, but your choice should be guided by operational context.
