Description

Choose THOR-603040 when a 30 × 40mm battery footprint is available and the project needs more capacity without moving to a 7mm or 8mm cell. The upgraded 800mAh version adds approximately 33% nominal capacity over the 5 × 30 × 40mm THOR-503040↗ while increasing nominal thickness by only 1mm. Compared with the 7 × 30 × 40mm THOR-703040↗, THOR-603040 saves 1mm of cell depth while giving up only 100mAh of nominal capacity. For designs that can accept 8mm thickness and need still more runtime, THOR-803040↗ provides 1000mAh in the same 30 × 40mm footprint.

The nominal 6 × 30 × 40mm dimensions describe the bare pouch cell, not the complete battery assembly. The current PCM-equipped drawing is approximately 6 × 30 × 42mm, and the usable installation envelope may also be affected by PCM placement, insulation, wire exit, connector position and cable bend radius. Reserve appropriate assembly clearance and normal pouch-cell dimensional allowance, then verify the production-intent drawing and finished samples before freezing the device enclosure.

At 3.7V nominal, the upgraded 800mAh THOR-603040 stores 2.96Wh. Based on the nominal 6 × 30 × 40mm bare-cell envelope, this corresponds to approximately 411Wh/L calculated volumetric energy density. This is an energy-density advantage, not evidence of a higher discharge rate. Actual runtime still depends on device load, standby current, wireless or sensor duty cycle, regulator efficiency, cutoff voltage, operating temperature and cell aging. Continuous and peak current, PCM limits, connector, wiring and charging requirements should be validated against the final device and approved battery configuration.

THOR-603040 Engineering & Fit Questions

How does THOR-603040 provide 800mAh in a 6 × 30 × 40mm cell?

THOR-603040 is an energy-density-optimized lithium polymer pouch cell. Its 6 × 30 × 40mm form factor achieves 800mAh (2.96Wh) through improved electrode chemistry and cell-level engineering, yielding a volumetric energy density of approximately 411Wh/L. This places it among the higher-capacity options in the 30 × 40mm footprint family, offering more stored energy per unit volume than the thinner THOR-503040↗ while remaining thinner than the THOR-703040↗.

Should I choose THOR-503040, THOR-603040 or THOR-703040?

All three share the same 30 × 40mm footprint but differ in thickness and capacity. THOR-503040↗ (5mm, 600mAh) suits the tightest enclosures. THOR-603040 (6mm, 800mAh) is the energy-density-optimized mid-range choice when an extra millimetre of thickness is available. THOR-703040↗ (7mm, 900mAh) provides the highest absolute capacity. Choose based on your available cavity depth and whether peak capacity or volumetric efficiency is the priority.

What is the finished size of the 800mAh THOR-603040 with PCM?

The nominal bare-cell size is 6 × 30 × 40mm. The current PCM-equipped drawing is approximately 6 × 30 × 42mm. The finished envelope may vary with PCM placement, insulation, wire exit, connector position and harness routing, so enclosure design should be confirmed against the approved production-intent drawing.

Does ‘high-energy-density’ mean THOR-603040 is a high-discharge battery?

No. ‘High-energy-density’ describes how much energy is stored per unit volume, not the discharge rate. THOR-603040 is rated at a standard 1C maximum continuous discharge (800mA), which is appropriate for steady-draw applications such as GPS trackers, environmental sensors and portable test instruments. If your application requires sustained discharge above 1C, consider a cell specifically rated for high-rate operation.

THOR-603040 3.7V 800mAh LiPo Battery – 6×30×40mm

THOR-603040 is a 1S 3.7V 800mAh high-energy-density lithium polymer (LiPo) battery built around a nominal 6 × 30 × 40mm bare pouch cell, providing 2.96Wh within a compact 30 × 40mm footprint. The upgraded 800mAh design increases capacity without increasing the nominal 603040 envelope, making it a strong option when a device needs more runtime than thinner 30 × 40mm cells can provide but cannot accept the extra depth of 7mm or 8mm alternatives. The current PCM-equipped drawing is approximately 6 × 30 × 42mm; final fit still depends on PCM, insulation, connector and wire routing.

Typical Applications — THOR-603040

Keychain Air-Quality & Environmental MonitorsTHOR-603040 is a strong fit for compact keychain air-quality and environmental monitors that need extended runtime within a shallow battery cavity. The 800mAh capacity and 6 × 30 × 40mm bare-cell geometry provide a useful balance between runtime, footprint and thickness for sensor-based connected devices. Validate sensor duty cycle, BLE/Wi-Fi or other wireless transmit peaks, operating temperature, charging profile and the finished-pack envelope before sample approval.

Compact Tracking & Location DevicesThe 800mAh capacity can suit compact asset trackers and portable location devices that need more runtime without moving to a thicker 7mm or 8mm 30 × 40mm cell. Validate GNSS, cellular or BLE transmit peaks, standby current, regulator cutoff and the finished-pack envelope before sample approval.

Compact Handheld Test & Measurement ElectronicsThe energy-density-optimized 6 × 30 × 40mm design can suit small rechargeable meters, diagnostic tools and handheld sensing electronics where 6mm nominal cell thickness provides a useful compromise between runtime and enclosure depth. Confirm display, sensor, continuous and peak-load requirements before sample approval.

Smart ID Badges & Connected TagsTHOR-603040 can also suit rechargeable smart badges and connected identification or information tags that combine BLE, display or periodic scanning functions within a compact enclosure. The 800mAh capacity can extend operating time while retaining the 6 × 30 × 40mm bare-cell geometry. Confirm wireless duty cycle, display activity, connector routing and the final finished-pack thickness for the device.
