Battery cars are not the answer, yet. Having worked for years with remote site telephone plant batteries, I've seen it. Rechargeable batts. are rated in amp hours (Ah). Based on draw, you can determine how long they can deliver power, not miles driven. The Ah rating is based on brand new condition, which degrades over time, even with limited usage. The batteries are temperamental, ideally 77 degrees. Higher temps are battery killers. Living in Arizona you might be looking at annual or bi-annual battery replacement. All these batteries WILL quit over time, in my experience. Many without warning at the most inopportune time. You can have a "test good" fully charged battery fail when under load. The best test is a load test, which is literally a 'controlled' short across the battery terminals. Warning! Never, ever try to short one of these batts. you may die. Use a load tester. This type of test will also sap the battery life. I never see the global warming, save the earth, green crowd mention the electric power required to charge these rechargeable batteries, it's huge. A rectifier which converts AC to DC is used for charging. Rated in amps, a dead batt. will initially suck your power up to the amp rating. Want to see your electric meter spin like a frisbee on steroids? These batteries will do it. In summation I'd say green cars are good for quick trips about town. The green crowd needs to understand that electricity does not magically appear at the power outlet. The batteries draw lots of electricity$$ The Batteries are expensive$$ The batteries are not dependable, especially if we get Chinese crap. Haven't seen it yet, but I believe we'll be seeing many, less than well off, people absolutely devastated when they need to drop several thousand $$ for a new set of batteries after a couple of years. 2011-05-16 13:42:28
