A smart battery is a rechargeable battery pack with a battery management system(BMS) built in. In addition to the normal positive and negative terminals, a smart battery has two or more terminals for connecting to the BMS. It can monitor voltage and current, as well as calculate charge level and soH (Status of Health) parameters. The smart battery can cease charging, request charging, or request that the smart energy user stop utilizing this battery's power. An IMPRES battery is also known as smart battery.

Smart batteries allow automatic, adaptive reconditioning, end-of-life display, and other advanced functions when used with a Smart charger. Data is saved in the battery and sent to the charger via a special smart communication protocol designed to maximize talk time and battery cycle life – all automatically.


• Made with PolyMax HPC cells.
• Uses high impact ABS and Poly-carbonate plastic for strength.
• Built to perform under standard operating conditions.
• Guaranteed to perform at 80% of original capacity for 12 months.
• Compatible to manufacturer specifications.


A smart battery charger is primarily a switch mode power supply (also known as a high frequency charger) that can interact with the battery management system (BMS) of a smart battery pack. The charging process is managed by the BMS rather than the charger, which increases system security. This method of communication, which is typically utilized for lithium batteries, is not available in all chargers. This communication technique, which is commonly used with lithium batteries, is not available in all chargers.

Overcharging is no longer a concern since smart chargers automatically check battery capacity, ensuring they are always safely charged to the right capacity and ready to go. When a battery reaches a certain capacity level, the battery manager is notified and the battery is removed from service. The chargers clearly display vital battery status information, assisting with inventory management.

There are three levels of smart battery chargers. Level 1 has been phased out since it did not provide chemical-independent charging and only supported a single chemistry.  Level 2 charger is entirely controlled by the Smart Battery and works as an SMBus slave, responding to voltage and current orders. Level 2 is also used for in-circuit charging, which is prevalent in laptops. A Level 3 charger, like a Level 2, can read directives from the Smart battery and can function as master. In other words, the Level 3 charger can request charging information.


IMPRES (Intelligent Motorola Portable Radio Energy System) is Motorola's industry-leading battery technology that performs preventative maintenance and reconditioning on your batteries when charged using IMPRES chargers. Motorola debuted IMPRES two-way radio batteries and chargers in June 2001, with a number of critical innovations that helped improve radio performance in the field and in the shop. Motorola's proprietary IMPRES technology aided in the development of smarter batteries and chargers, removing the guesswork from charging. The charger now offered a visible display of battery capacity, and smart charging algorithms prevented overcharging and overheating, all of which helped to improve the battery's talk time and total cycle life.

One of the issues we experienced with each battery was that consumers would overcharge them, causing the batteries to overheat, reducing the total life of the battery. Another concern is undercharging, which, when done repeatedly over a long length of time, reduces the cycle life of a battery. However, IMPRES batteries could not be overcharged. You could leave them in their chargers for a week and not worry about them.
IMPRES batteries are significantly less expensive in the long term than other batteries since they are more reliable and last longer. All main city departments, including police, fire, rescue, and public works, use IMPRES batteries to power two-way radios. IMPRES smart battery chargers provide useful battery status information while also extending battery life.


• Provides state-of-charge and full charge capacity, depending on capacity estimations.
• Charger is set to the appropriate algorithm.
• Reminds the user to do routine maintenance.
• Prevents unauthorized usage of the battery.


• It raises the price of a battery by 25%.
• Complicates the charger; most intelligent battery chargers are hybrid and can also service non-intelligent batteries.
• Periodic calibration is required.
• The readout only displays the state of charge and not the actual runtime.


• After three months or every 40 partial cycles, calibrate a smart battery by performing a full discharge and charge. Batteries with impedance tracking allow for some self-calibration.
• A fuel indicator that reads 100 percent SoC does not guarantee a healthy battery. The capacity may have faded to 50%, slashing the duration in half. A fuel gauge can offer the impression of safety.
• Replace the batteries with the same manufacturer if feasible to avoid incompatibility issues with the device and/or charger. Always test the battery and charger before using them.
• When utilizing a smart battery that does not appropriately display its status of charge, proceed with caution. This battery may be defective or incompatible with the device.
