Without listening to a long commercial to buy a $49.00 book, Anybody know the 'gimmick' for never buying a battery again. The ad on the "box" says a man taught him how in 10 minutes, now the two of them want $49.00 for the "book" of knowledge. Just wondering.
Pretty hard to re-write the rules of chemistry and physics. The causes of battery failure are well known and well documented, some time with google and you can probably save the $49.99. For Example: http://batteryuniversity.com/learn/archive/what_causes_car_batteries_to_fail
The gimmick is, when your battery goes dead, you just buy a new car with the profits that you made from selling the stupid battery book.
I doubt it has anything to do with preservation of your battery, but more likely a way to keep getting replacements under warranty. However, even that is doubtful, since typically only the balance of the original warranty applies to replacement batteries. Save your 49.99.......that will cover at least half of the next new battery you buy. Buy the book and you'll still be buying a new battery in due time. Ray
The book is an easy score. Its the decoder ring that makes it all readable. Send me 19.95 plus shipping, sorry no personal checks or COD accepted.
Yeah !!! What he said Serious question that has nothing to do with batteries - in all of your engineering education and adventures have you had to plan or adjust or calculate a project with respect for the earths curvature?
There are plenty of web sites and videos on reviving batteries. Most times they are sulfated. A special charger using alternating current is supposed to break down the sulfation. You can buy a charger or make one. Have also heard of using certain chemicals to add to or replace the acid. If you have some old batteries laying around why not experiment? What have you got to lose?
A surveyor friend told me there are basically 2 theories of surveying 1) the earth is flat 2) the earth is round The first theory is easier and good enough for surveying house lots. The second is harder but must be used for surveying roads and large areas of land because it takes account of the curvature of the earth. He told me this 40 years ago, I expect by now there are computer programs that do the hard math for you.
GPS and a calculator. Used to be logarithm tables and a slide rule. Civil designers still use equations, sometimes they plug them into a spreadsheet but everything still has to be calculated. As for the battery, I used to know an old guy that sold used batteries, if the plates hadn't shook loose he flushed them and filled them with fresh acid.
When I Lived in Tuscon, AZ there was a Guy that Sold Rebuilt Batt. he Made a Lot of Money he use to cut the Top off & clean them out Check the plates & recharge Them just my 3.5 cents or when the Cows home!
Don't know if this counts but I always rank and support my firewood in such a way that the centrifugal force of the earths rotation doesn't make it fall over.
I would have thought that parallel to the equator would be more stable. Also, check with astronomers or cosmologists because the tilt of the earth's axis varies over time. You may have to dial in or out a few degrees.
The only difference in the cheap ones and the more expensive ones is that you get a longer warranty with the more expensive one. You don't get a better battery, the money goes toward the warranty.
Man never buy another (battery) Catalog? Waste of money for that i would think. All it gona say is replace the acid or distilled water and leave it upside down for some time and then slow charge the thing. Idk im just talking but i did youtube some bs and i dont believe none of it. Just get the el cheapo from walmart and see if autozone will give you core store credit to buy a soda.
That's not entirely true, probably true for some cheaper brands but not all. You're paying for plate size/area, with 'better' batteries having larger plates. Bigger plates, more current available. As batteries age, sulfation reduces area and performance drops off. One issue with larger plates is when the battery does sulfate, the sulfate drops to the bottom of the cell and shorts them out. Bigger plates extend down into the cell further, so they will fail 'faster' as distance from the bottom of the cell to the plates is smaller.
I agree with Steve, you do get a better battery if you spend more (usually). But the increase in price, is not proportional to the increase in battery life. Pay twice as much, it'll last 30% longer.
