How Does Temperature Affect Battery Performance?
NiMH chemistry maintains functionality across wider temperature ranges than lithium variants, but users should understand these operational parameters:
| Temperature | Capacity Available | Recommended Usage |
|---|---|---|
| -20°C to 0°C | 70-85% | Short emergency use |
| 0°C to 25°C | 95-100% | Normal operation |
| 25°C to 45°C | 85-90% | Reduce discharge rate |
In cold environments, keep batteries close to body heat when possible. For high-temperature scenarios (>35°C), limit continuous use to 45-minute intervals. Thermal imaging tests reveal the Tenergy pack maintains 8°C cooler surface temps than comparable NiMH units during 2A discharges, thanks to its optimized cell spacing and vent design.
Why Choose NiMH Chemistry Over Other Battery Types?
NiMH strikes an optimal balance between performance, safety, and environmental impact. Its 1.2V nominal cell voltage prevents overvoltage damage in legacy devices designed for alkaline batteries, unlike lithium’s 3.7V per cell. For industrial users, the chemistry’s tolerance for partial state-of-charge storage reduces maintenance costs – you can shelf the battery at 40% charge for 6 months without significant degradation.
FAQ
- Q: How many charges does it take to break in the battery?
- A: Perform 3 full discharge/charge cycles initially to maximize capacity.
- Q: Can I mix old and new Tenergy cells?
- A: Never mix batteries with >20 cycle count difference – this causes uneven loading.
- Q: Why does my charger show different mAh than labeled?
- A: Actual capacity varies by usage. New batteries may deliver 1950-2050mAh due to manufacturing tolerances.
