3 to 4 years is about average. Run it down and you cut it's life each time you do this. I have seen them last 7 years and I have seen them last 1 year. There is no real guarantee.
most battery last five years
The average car battery last around three years. The battery life may shorten, if the car is in extreme heat or cold, lights are left on often, and if the car is enchanced for racing.
Car batteries last four to five years on average.
No, but they will not last as long, and because of this, in most cases it's actually "cheaper" to buy reliable brands of batteries.
Most car batteries contain Sulphuric acid.
Car batteries are not make or model specific. Most car batteries last approximately five years. After five years it is just a matter of time as to when the battery will fail. Obviously the brand and type of battery you buy will affect the lifespan, ie: you buy a cheap battery and you will not get a decent lifespan. It is generally a good idea to check the warranty on a battery before buying it, this will give you some idea of how long it will last.
No, the batteries in an electric car are much different. Normal automotive batteries are lead acid batteries. Most electric cars use Lithium-Ion batteries.
Most are, yes.
how long is a piece of string
An RC car battery will likely last more than a year. They vary from battery to battery, however, technological advances in recent years have greatly increased the time that these batteries last.
3 to 6 years is normal range.
An electric car needs to be charged until the indicator on the charger says the batteries are charged. It will depend on the amperage of the batteries, the way the charging mechanism works, and the percentage of discharge of the batteries.
