What type of battery is typically used in hybrid vehicles?

Hybrid vehicles typically use nickel-metal hydride (NiMH) batteries due to their ability to provide a good balance of energy density, power capacity, and longevity. NiMH batteries have been widely adopted in many hybrid models because they are well-suited for the variable demands of hybrid systems, which require quick bursts of energy for acceleration while also needing to retain a significant capacity to enable longer electric-only driving ranges.

Additionally, NiMH batteries perform well in a range of temperature conditions and have a proven track record in automotive applications. They are capable of recycling and have less environmental impact compared to some of the alternatives.

While lithium-ion batteries, which are growing in popularity due to their higher energy density and lighter weight, are often found in more recent hybrid and electric vehicles, NiMH remains the standard in many established hybrid models. The other types of batteries mentioned are less suitable for the specific requirements of hybrids, as lead-acid batteries are generally bulkier and not as efficient for high discharge applications, alkaline batteries are primarily for small electronics and not designed for automotive uses.
