Review on USB Rechargeable Lithium D Batteries - 1.5V / 4000MAh (2-Pack) - ECO-Friendly & Recyclable - No Memory Effect - Not NI-MH/NI-CD/Alkaline Batteries by Donna Lawson

Revainrating 5 out of 5

Works for my "Energizer LED Folding Lantern "

These D size batteries last a long time in my lantern. In six months, I have charged them once. One takes about 10 hours to charge with my "Tripp Lite 4-Port USB Charging Station with OTG Hub", I used the 2-amp/ 5-volt outlets. A red light shows when they are charging and the light changes to green when it is fully charged. The cap is held next to the body by a short rubber band covered in cloth. They are nice because they store SO much energy.

Pros
  • ▶D LITHIUM BATTERY - Not like Alkaline, NI-MH, NI-CD batteries, the Lithium D cell features NO Memory Effect to reduce the capacity over time, longer life, more eco-friendly. Improved low self discharge function could help to maintain the capacity up to 75% even if 3 years non-use.
Cons
  • May not work with all types of flashlights
