Which of the following battery chemistries is rechargeable?
- A.Nickel-metal hydride
- B.Lithium-ion
- C.Lead-acid
- D.All these choices are correct (correct answer)
WhyNickel-metal hydride, lithium-ion, and lead-acid are all rechargeable battery chemistries. Nickel-metal hydride, lithium-ion, and lead-acid are all common rechargeable battery chemistries widely used in amateur radio gear, from handheld battery packs to backup power systems, so all three choices are correct, answer D. Picking just one of A, B, or C would incorrectly exclude the other two valid rechargeable chemistries.
