Lithium-Ion Rechargeable Equipment

Rechargeable batteries can now be used for almost any purpose except certain sensitive electronic devices or situations where longevity is critical, such as emergency equipment. The technology has improved; our new rechargeable batteries report identifies best-performing rechargeables  for AAA, AA, and D-sizes.

When to Use

Look for lithium-ion (Li-ion) technology as a feature in rechargeable equipment purchases, such as flashlights or power tools. Usually these batteries are contained in special battery packs or are not replaceable. There are also a few kinds of specialized electronic equipment that are designed for 3.7 volts Li-ion batteries.

Why Go Green

Waste impacts

All used batteries - whether rechargeable or not - must be recycled, not disposed in the trash. Because one rechargeable battery can replace hundreds of non-rechargeables, the waste impact is reduced dramatically. Older nickel-cadmium rechargeables - still sometimes found in power tools - have considerably more toxic heavy metals.

 

Criteria for Batteries

Specifications for AA Rechargeable Batteries

  • Nickel-metal hydride (NiMH) chemistry
  • Minimum 2000 mAh capacity
  • Low self-discharge (LSD): Maintains a minimum of 80% capacity after 1 year in storage, or 75% after 3 years in storage

Specifications for AAA Rechargeable Batteries

  • Nickel-metal hydride (NiMH) chemistry
  • Minimum 800 mAh capacity
  • Low Self-Discharge: Maintains a minimum of 80% capacity after 1 year storage, or 75% after 3 years storage

Specifications for D Rechargeable Batteries

  • NiMH chemistry
  • Minimum 8000 mAh capacity
  • Low Self-Discharge: Maintains a minimum of 80% capacity after 1 year in storage, or 75% after 3 years in storage

Non-rechargeable alkaline batteries are acceptable for precision electronic equipment that is voltage sensitive, for emergency use equipment, or for other applications requiring longevity and slow power drain.
