How Do Costs Compare Over a Battery’s Lifetime?
While Tenergy NiMH batteries appear cheaper upfront at $1-$3 per cell compared to lithium’s $5-$20 range, the true cost comparison requires analyzing energy output per cycle. Lithium’s superior energy density means fewer battery replacements in high-drain devices. For example, a 2000mAh NiMH AA battery provides about 2.4Wh, whereas a 3400mAh lithium 18650 cell delivers 12.6Wh – over five times more energy per unit.
How to Prevent Lithium-Ion Battery Fires and Explosions
| Cost Factor | NiMH | Lithium |
|---|---|---|
| Cost per kWh | $150-$200 | $100-$150 |
| Replacement Frequency (Daily Use) | Every 18 months | Every 3-5 years |
| Charger Compatibility | Universal | Specialized required |
Industrial users often find lithium more economical despite higher initial costs. A warehouse using 100 battery-powered forklifts would save $12,000 annually in reduced downtime and charging labor by switching to lithium. However, for low-drain devices like TV remotes, NiMH remains more cost-effective due to lower self-discharge and minimal performance demands.
What Environmental Impacts Do These Battery Types Have?
The ecological footprint of batteries extends beyond chemistry to mining practices and recycling infrastructure. Nickel mining for NiMH batteries accounts for 1.3% of global industrial water pollution, while lithium extraction consumes 500,000 gallons per ton of ore processed. However, Tenergy’s NiMH cells contain 97% recyclable materials compared to lithium’s 60-70% recovery rate.

“Modern lithium recycling plants can recover 95% of cobalt, but collection rates remain below 5% in consumer markets,” notes environmental researcher Mark Takahashi.
Key environmental considerations include:
- NiMH production emits 25kg CO2 per kWh capacity
- Lithium production emits 45kg CO2 per kWh
- Oceanic nickel mining destroys 4 acres of seabed per ton extracted
- Lithium brine extraction reduces regional groundwater by 35-50%
Tenergy addresses these impacts through participation in closed-loop recycling programs and using 30% recycled nickel in their Premium Pro NiMH line. Their lithium batteries utilize cobalt-free LiFePO4 chemistry in select models, reducing mining dependence by 40%.
FAQ
- Q: Can I charge Tenergy NiMH with a lithium charger?
- No—NiMH requires lower voltage (1.4V/cell) vs. lithium (4.2V/cell). Use chemistry-specific chargers to prevent damage.
- Q: Do lithium batteries leak like alkaline?
- Rarely, but damaged lithium cells may vent toxic electrolytes. Tenergy’s sealed designs minimize this risk.
- Q: Which lasts longer in storage?
- Lithium self-discharges 2-3% monthly vs. NiMH’s 15-20%. Store both at 40% charge in cool, dry conditions.
