● Two Compact Cell Sizes: Choose between Ø11.2 × 29.8mm and Ø12.6 × 42.9mm configurations according to the available installation space. ● 450–1200mAh Capacity Options: Multiple capacities help balance cell size, weight and expected equipment runtime. ● 1.2V Rechargeable Chemistry: NiMH chemistry supports rechargeable equipment designs requiring a nominal cell voltage of 1.2V. | ● Button-Top and Flat-Top Designs: The button-top model supports compatible battery contacts, while flat-top cells are intended for battery pack integration. ● Specified 1C Discharge Rate: The five models provide reference currents from 450mA to 1.2A according to their rated capacities. ● Custom Pack Support: Flat-top cells can be evaluated for tabs, leads, connectors, insulation and multi-cell pack configurations according to project requirements. |
▶ NR29N450J: Consider this model when compact height, low weight, and a button-top terminal are the primary requirements.
▶ NR43N1100P: A 1100mAh flat-top cell with a listed internal resistance of 30mΩ for custom battery pack integration.
▶ NW43N1100P and MT43N1100P: Alternative 1100mAh models using the Ø12.6 × 42.9mm flat-top format. Final selection should be based on the applicable cell specification and project requirements.
▶ NW43N1200P: Provides the highest capacity and longest theoretical runtime among these five models in the 43mm cell format.
Based on recent customer requirements, these N Series cells are particularly relevant to compact industrial, gaming controllers and electronic equipment requiring rechargeable 1.2V cells, moderate discharge current and flexible battery pack configurations.
N Series NiMH cells can be evaluated for rechargeable gaming controllers, wireless gamepads and related interactive entertainment accessories. Compact cell sizes and custom pack options help manufacturers balance installation space, product weight and operating time. The selected cell configuration, voltage, connector and charging method must be matched to the controller’s electrical and mechanical design.
The 450mAh model supports compact and weight-sensitive designs, while the 1100mAh and 1200mAh cells can provide longer theoretical runtime for LED lighting, indicators and solar-charged electronic equipment. The charging method and outdoor operating conditions must be evaluated for each project.
The 43mm flat-top cells can be evaluated for handheld instruments, portable controllers, data-collection terminals and other moderate-load industrial electronics with capacity requirements around 1000–1200mAh.
The compact cylindrical format can be integrated into rechargeable asset trackers, monitoring nodes and other low-power IoT equipment. For products with long standby periods, self-discharge performance, charging frequency and operating temperature should be confirmed during cell selection.
| Configuration | Nominal Voltage | 450mAh Energy | 1100mAh Energy | 1200mAh Energy |
| 1S1P | 1.2V | 0.54Wh | 1.32Wh | 1.44Wh |
| 2S1P | 2.4V | 1.08Wh | 2.64Wh | 2.88Wh |
| 3S1P | 3.6V | 1.62Wh | 3.96Wh | 4.32Wh |
| 4S1P | 4.8V | 2.16Wh | 5.28Wh | 5.76Wh |
| 6S1P | 7.2V | 3.24Wh | 7.92Wh | 8.64Wh |
The values above are calculated references. Connecting cells in series increases pack voltage and energy but does not increase the Ah capacity or the corresponding 1C current. Final pack design must be matched to the equipment load, charging system, installation space and operating environment.
To evaluate a suitable N Series cell or custom NiMH battery pack, please provide the following project information:
● Required pack voltage and capacity
● Continuous and peak load current
● Available installation space
● Expected operating time per charge
● Charging method and charger specifications
● Charging, discharging and storage temperatures
● Terminal, wire and connector requirements
● Expected cycle life and applicable compliance requirements
Share your available installation space, load current, expected runtime, charging method and pack voltage with Grepow. Our battery team can help evaluate a suitable N Series cell or custom NiMH battery pack configuration for your equipment.
The flat-top models can be evaluated for custom pack configurations using welding tabs, leads, connectors, insulation and labels. The final structure must be designed according to voltage, load, charging, temperature and mechanical requirements.
The NW43N1200P provides the highest capacity in this series, offering 1200mAh within the Ø12.6 × 42.9mm flat-top configuration.
Button-top cells are designed to make contact with compatible mechanical battery terminals. Flat-top cells are generally more suitable for tab welding and integration into custom battery packs.
