The range will vary according to where you live but the avrage is 25 to 501 miles on just electricity. After that you switch to gas and get an average of 344 miles to the 9.3 gallon tank.
if you mean shelf life they last for years if stored properly
Now adays about 36 - 48 months is all you get from one.
You do not charge a 7.2 volt battery with a 9.6 volt charger period unless you want to ruin the battery. You charge it with a 7.2 volt charger.
Like any type of battery, an electric car batteryhas limited capacity, which means that it can only store a certain amount of electrical energy. How long the battery lasts in your electric car depends on its capacity and how it is used. On average, a fully charged battery in an electric car will last between 150 and 300 miles. You can recharge the battery with a plug in the wall, so you don't have to worry about electric car battery cost every time it runs out. Electric car battery technology is constantly advancing, and in the future there are expected to be electric cars that can last even longer between charges.
This will depend on the size of the 12 v battery.
No set answer to that. Depends on the power rating of the motor and how hard you're running it.
The answer is going to depend on the size of the battery and what you are mowing. 12-volt batteries provide 30 - 40 minutes of mowing time; 24-volt mowers last 40 - 75 minutes; and 36-volt mowers run for up to 90 minutes. If your lawn is thick, lush or tall then the charge may not last as long.
Absolutely not! It is a 14 volt drill. Use a 16 or 18 volt battery will destroy the drill in short order. It will run but not for long.

Electric cars rely solely on batteries for their power. The most important function of an electric car battery is running the electric motor. This means that the battery in an electric car has to be able to last for a long time and not take too long to recharge. While the batteries that are in electric cars currently on the market are not as efficient as everyone would like, some serious improvements are being made to change this.
As long as the ATV is wired 12 volt, not 6.
It takes about 6 hours to charge a 7.4 volt battery when using a 5 volt charge. For the best results try charging it over night.
