What is the HKNN4013 High-Capacity Battery?
The Motorola HKNN4013 (also sold as the HKNN4013A and known by the model name BT90) is a high-capacity 1800 mAh, 3.7 V lithium-ion rechargeable battery for Motorola CLP-series, CLPe-series, and DLR-series two-way business radios. On CLP and CLPe radios it extends operating time and requires the larger HKLN4440 high-capacity battery door, which is sold separately; on DLR radios it serves as the standard factory battery and needs no additional door. Its primary function is to power compact Motorola business radios through extended shifts of push-to-talk communication.

What's in the Box
The HKNN4013 ships as a single high-capacity lithium-ion battery. It does not include a charger or a battery door. CLP and CLPe radios require the HKLN4440 high-capacity battery door, which must be ordered separately to seat this battery. DLR radios use this battery as their standard battery and need no additional door.
Who This Product Is For
The HKNN4013 is used wherever Motorola CLP, CLPe, or DLR radios are deployed and operators need to cover a full shift without swapping or recharging mid-day. Because these are compact, license-free business radios, the battery is most common in customer-facing and operations environments rather than public-safety or heavy-industrial fleets.
Typical settings include:
- Hospitality — hotels, restaurants, catering, and event venues where staff carry low-profile radios through long service periods.
- Retail — sales floors, stockrooms, and back-of-house teams coordinating across a store or shopping center.
- Education — front office, facilities, and event staff at schools and campuses.
- Healthcare and assisted living — support, housekeeping, and front-desk teams in facilities that favor discreet, lightweight radios.
- Warehousing and light industrial — DLR-series users who need on-site, infrastructure-free communication and extended runtime.
It is the appropriate choice when standard-capacity runtime is not enough for the work period and when keeping a charged spare on hand reduces downtime.
Key Features
- 1800 mAh lithium-ion cell at 3.7 V DC.
- High-capacity rating, providing longer runtime per charge than the standard-capacity HKNN4014 (1130 mAh) battery.
- Compatible with Motorola CLP, CLPe, and DLR business radios.
- Functions as the standard battery on DLR-series radios and as a high-capacity upgrade on CLP and CLPe radios.
- Requires the HKLN4440 high-capacity battery door for use on CLP and CLPe radios; no separate door is needed on DLR radios.
- Recharges in approximately 3.5 hours.
- Rated for operation from -10 °C to +60 °C (14 °F to 140 °F).
- Genuine Motorola battery covered by a one-year manufacturer warranty.
Frequently Asked Questions
Which radios is the Motorola HKNN4013 compatible with?
The HKNN4013 fits Motorola CLP and CLPe series radios — including the CLP1010, CLP1040, CLP1060, CLP1010e, and CLP1080e — and DLR series radios such as the DLR1020 and DLR1060. On CLP and CLPe radios it operates as a high-capacity battery and requires the HKLN4440 high-capacity battery door. On DLR radios it is the standard battery and needs no additional door.
Do I need a different battery door to use the HKNN4013 on a CLP radio?
Yes. The HKNN4013 is physically larger than the standard CLP battery, so CLP and CLPe radios require the HKLN4440 high-capacity battery door (sold separately) to seat it. The standard CLP battery door will not close over this battery. DLR radios do not require a separate door.
How long does the HKNN4013 last on a single charge?
On CLP and CLPe radios, the HKNN4013 provides up to approximately 18 hours of operation. On DLR radios it provides up to about 15 hours with the Battery Save feature enabled. Both figures are based on a standard duty cycle of 5% transmit, 5% receive, and 90% standby; actual runtime varies with transmit volume, signal conditions, and feature settings. The battery recharges in about 3.5 hours.
What is the difference between the HKNN4013 and the HKNN4014?
The HKNN4013 is the high-capacity battery at 1800 mAh, and the HKNN4014 (model name BT60) is the standard-capacity battery at 1130 mAh. The HKNN4013 delivers longer runtime per charge but requires the HKLN4440 high-capacity battery door on CLP and CLPe radios, whereas the HKNN4014 fits the standard battery door that ships with the radio.
Is the HKNN4013 the same as the BT90?
Yes. BT90 is Motorola's model name for the HKNN4013 (and its HKNN4013A variant). Listings that reference the BT90, HKNN4013, or HKNN4013A are describing the same 1800 mAh high-capacity lithium-ion battery.
Is the HKNN4013 a genuine Motorola battery, and is it under warranty?
The HKNN4013 is an original Motorola lithium-ion battery and carries a one-year Motorola limited warranty. Using a genuine Motorola battery helps maintain expected runtime and safe charging behavior in Motorola chargers.
The HKNN4013 shows as discontinued — is it still available?
Motorola has marked the original HKNN4013 part number as discontinued and directs CLP and CLPe replacement buyers to the same battery under the SKU HKNN4013ASP01. The battery itself — the 1800 mAh BT90 — is unchanged. Availability varies by stock; contact Tech Wholesale to confirm the current part number and supply.
