Car battery question?

Posted on May 21, 2012 by admin| 9 Comments

My car battery is coming up to 5 years old. It still performs ok and a hydrometer test says it’s ok(4 cells well into the green and 2 cells on the border of the green and white). However if i look into the battery you can see white deposits that would remind you of frost on top of the plates. Is this normal and ok? Reason i ask is because the battery provides plenty of power and the hydro test says it’s ok.
Can’t seem to answer my own question, anyway the corrosion is not on the posts it’s inside the bttery on the plates, I thought maybe if the hydro readings are quite good i was hoping the white depeosits inside the battery are harmless.

This step works well for resins that are less expensive and do not tolerate extensive UV exposure. The tape filters the UV and also locks the cells in place. There are several UV resistant Duct Tapes and other power adhesive tapes on the market. I like standard White Strapping Tape

Back encapsulation is the best option in my opinion. The advantage is, no need for expensive silicone encapsulants. The back encapsulation prevents much of the resin from UV exposure. These are dew safe water tight 100% The humidity is as bad as it can get where we live. If they do not get wet here, they are safe anywhere. Buster was about 3 years old when he wandered in the veterinarian’s office in early 1995 while our dog Sweetie was getting her yearly shots. We took him home:-) 16 great years. If not for the rare lymp cancer that started 5 months ago, he would have lived a few more years. He passed away while I was filming the foggy camera section of this video.

See Through Solar Cells

Posted on December 21, 2011 by admin| 50 Comments

Fifty years inthe making, solar-power cells are still flat, rigid, and ugly. But new research shows how they could be made lightweight, flexible, and transparent. These innovations could expand solar-cell use to things like solar fabrics and power generating windows. www.sciencentral.com

short video describing a small solar power system that i set up at my house. it consists of twelve 1 amp solar panels (15 watts each for a total of 180 watts of power – per hour). i use it to run all lights (CFL’s), fans, tv’s, and stereos in the house. also the microwave, coffee maker, blender, can opener, sandwich grill, toaster, vacuum, computer and anything else i can think of. run time for lights/fans only is approx 8 hours. add in vacuuming, microwaving or toaster along with lights, tv and the fans and the run time is reduced to 4-5 hours a day. i bought solar panels, inverter (1000 watt) and killowatt meter at Harbor Freight tools, the batteries (deep cycle) from walmart and the battery cables from checker auto. total cost was about 00 to 00 For the latest including EXTRA PICS and INFO. – Click on the “WEBSITE LINK” from my youtube channel page.

Car Battery: When is a Car Battery Complete Toast vs. When Can it be Re-Charged?

Posted on December 21, 2011 by admin| 8 Comments

Standard car battery (PowerVolt – an Interstate Brand). Not deep cycling or gel or anything other than a run of the mill car battery. It has water in cells.

Headlights were left on – for like weeks. I suppose they weren’t putting out any light after some number of hours, but the lights were left in the on position.

It is used for off-road activities, and had been left sitting with the lights ‘on’ for at least a week.

It can be jump-started, though.

The battery is about a year old – if that makes any difference.

The question:

(I know there are no absolutes, but there are 99% likelihoods).

Is the battery most like completely dead / history / toast / past-tense or might it be re-chargeable ?

What are the odds of each, in your estimation ?

Thanks.
