Hybrid vehicle technology swept the market almost 20 years ago. After being introduced, it has been an ever-growing market for hybrid vehicles due to its inherited fuel efficiency and smooth driving experience. When compared to combustion engine driven vehicles, hybrid vehicles acquire power through both combustion engine and a high voltage battery pack, charged using regenerative braking. This article elaborates more about this battery pack from a perspective useful to a hybrid vehicle user.

Today, there are 2 types of batteries utilized in hybrid vehicles: Lithium Ion, Nickel Metal Hydride (NiMH) batteries. Hybrid vehicles contain a battery made up of number of cells and each of them are bridged together to produce the charge required to drive the electric motor of the vehicle. Mentioned below are the pros, cons, and details about them in summary.
Lithium-Ion Batteries:
used in hybrid vehicles where more hose-power in needed. And the life expectancy is about 15 years with a mileage of 150,000 miles, which is the average highest life expectancy of all hybrid battery types. Causes heat related problems more often and when it comes to replacement the cost is significantly high.
Nickel Metal Hydride (NiMH) Batteries:
This is the most widely used battery for hybrid vehicle power generation the current market. More affordable than lithium-ion batteries and are easily rechargeable. This kind of batteries are more versatile, stable, and less expensive also.
lifetime is about half of lithium-ion batteries and unlike them, nickel metal hydride batteries are not very environment friendly due to the toxic chemicals used to produce them.
For both batteries, their lifetime decrease depending on the circumstances they are placed. Especially when exposed to certain levels of temperature for a longer period.

Heat makes batteries work harder. In nickel-metal hydride batteries, excessive heat can cause bulging or bubbling. This leads to electrolytes inside of the hybrid car battery to evaporate, which in turn means the battery loses its ability to recharge properly. Long story short, this shortens the length of car batteryโs life.
For Lithium-ion batteries also, the optimum temperature to keep them is between 5 โ 20 Celsius, while 15 Celsius being the optimum temperature. Hence in any country with tropical climate or any country that has a summery weather both of these battery types will decay out their capacity well before the guaranteed time period.
Other than the heat there are two other main causes for the deterioration of batteries. First one is not properly maintaining the battery cooling blower or the cooling system and the second one is not using the vehicle at a sufficient level so that the battery will charge and discharge itself out. Both of these scenarios are quite easily avoidable if proper attention is paid.
