Description
High-Capacity Replacement Lithium-Ion Power Cell for Slim Portable Radios
Restore maximum shift uptime and lightweight operational reliability to your handheld fleet.
The Motorola HKNN4013B (also known as the BT90) is a genuine original equipment manufacturer (OEM) high-capacity lithium-ion rechargeable battery engineered for ultra-thin portable business two-way radios. Integrating the Motorola HKNN4013B or BT90 battery into your equipment setup ensures your staff stays connected through extended work shifts without sudden power drop-offs. Designed to provide extended talk time while maintaining a low-profile form factor, this premium power cell balances an upgraded 2300mAh energy density with a lightweight physical footprint. The Motorola HKNN4013B is the updated version of the Motorola HKNN4013A and Motorola HKNN4013.
Fabricated with top-tier internal lithium cells, this battery pack features built-in protection circuitry to shield against overcharging, short circuits, and unexpected thermal spikes. The outer casing is constructed from high-impact composite polymers designed to absorb daily drop shocks on retail floors, dental offices, industrial job sites, and hospitality environments. For deployment with ultra-compact radios like the CLP series, this deep-capacity cell provides up to 18 hours of continuous operation, though it requires a high-capacity battery door to secure properly due to its extended cell depth.

Frequently Asked Questions
Is this battery compatible with the compact CLP earpiece radio series?
Yes. The Motorola HKNN4013B is the designated high-capacity battery upgrade for the CLP1010, CLP1040, and CLP1060 units. Because it is slightly thicker than a standard battery, you must use an extended battery door (HKLN4440) to enclose it.
What is the relationship between the HKNN4013B and the BT90 model names?
They represent the exact same physical product. HKNN4013B (updating the old HKNN4013A part code) is the official factory hardware SKU number, while BT90 is the consumer-facing marketing model designation used by Motorola.
Does this battery suffer from memory degradation if docked while partially full?
No. Utilizing clean lithium-ion chemistry, this cell contains no memory effect tendencies. It can be docked inside a multi-unit charger tray or single desktop station at any point during a shift without losing underlying capacity.
Can I use my old standard battery door when installing this on an SL300 radio?
Yes. When sliding this battery pack into SL series radios like the SL300, SL7550, or SL2600, it utilizes the standard built-in battery compartment dimensions and does not require an specialized deep door upgrade.
How long does this battery cell take to achieve a full charge from empty?
When placed inside an authorized Motorola lithium-ion rapid desktop charging cradle, the battery block typically scales from a depleted state to a complete 100% full green status in approximately 3 to 3.5 hours.
What baseline manufacturing warranty parameters cover this battery tool?
This authentic original equipment manufacturer power component comes fully backed by standard structural factory coverage guidelines to handle premature drop-offs or component flaws.
Is HKNN4013 the same as HKNN4013B?
Yes, the HKNN4013B is the latest version of the product with model number HKNN4013. It acts as the direct factory-approved replacement for all previous generations and legacy suffix letters in this exact battery line.
