### ⭐⭐⭐⭐ Love the technology, but battery information was misleading
*by S***R on September 2, 2025*

As someone who already owns a lot of NiMH batteries, I wanted to buy this sterilizer over the other version with a built in Li-Ion battery. The user manual said I should be able to get 100 uses out of a set of 4 NiMH’s before needing a recharge, however, once I got the unit, I realized that I could only get 25 uses until the batteries require a recharge. I’ve learned that this unit requires a high discharge rate out of batteries, which NiMH or Alkaline are not great at. Lithium batteries are ideal for high discharge rates (and they are conveniently lighter than 4 AA NiMH’s). I think the only reason to get this version over the lithium ion version, is that this one can accept single use lithium batteries. Single use lithiums can handle extremely high and low temperatures, making them versatile for backpackers who work outside of the ideal working temp ranges of lithium rechargable.
