Battery mystery solved

Battery mystery solved!
Our current deep cycle battery mystery began on January 17, 2010. That was when we posted to you about our Crown batteries being undercharged [link]. If you click on this link to that blog story, you'll find another link to the Crown Battery website which contains battery charging specs for our deep cycle batteries.

However, between January 17th and now, the specs on that Crown Battery page changed or were corrected. Fortunately, I downloaded the older page to my computer and am able to read both pages for comparison. [There are links to both Crown pages on yesterday's blog post].

So, the battery mystery is now solved. The specific gravity for a fully charged Crown Battery is NOT 1.280. It is 1.265!!

We now know the following things:
  • The old battery charge controller [Blue Sky Solar Boost 50] was undercharging our solar battery bank.
  • On January 17th, the specific gravity [SG] of our battery bank showed only a 75% charge.
  • All of our batteries now are 1.265 SG or greater, indicating a 100% charge.
  • Also from the current Crown specs, the Absorption Charging voltage is 14.5 volts, not the impossible to achieve 15.0 volts.
Last nite the regulation voltage setting on our new Morningstar TriStar battery charge controller was changed from the unachievable 15.0 volts to 14.5 volts. This new lower setting will allow the TriStar to shift into Pulse Width Modulation [PWM] mode.

We are soooooo excited about finding out all of this stuff. And we thank all Readers who have sent advice to leading us to solve our battery mystery!

8:30AM - MsTioga on the road again!
In case you did not tune in for a few days, MsTioga and The Team have left Aticama and the Beach of Matanchen! We are now south of Puerto Vallarta, searching for Adventure!

One of the things that we want to learn on this trip, is how far south our Mr. Datastorm is able to connect to the internet. Mr. Datastorm received a new 2-watt transmitter during our recent trip to California. The old transmitter which burned out had only 1-watt of power. Mr. Stave O'Bosky [our Datastorm dealer] believes that this new 2-watt transmitter may allow us to connect all over southern Mexico!

11AM - Pueblo of El Tuito
We arrived at El Tuito and are intrigued by the entrance road to this pueblo which has two lanes in each direction. Very unusual for a small town in the mountains of Mexico.

MsTioga has made a Breakfast Camp on a nice residential street next to a garden. Behind us is a soccer field with a huge concrete stadium. Wow! El Tuito is different!

5PM - Nite Camped in Tomatlán
MsTioga pulled out of El Tuito around 2pm. We began a long elevation descent from 3,500 feet down to 150 feet above sea level. Once out of the heights of the Sierra Madres, we traveled thru farm land. Lots of sugar cane and fruit trees here.

We saw a highway sign pointing east to Tomatlán, and decided to take a peek. We have made a Nite Camp here near another large soccer field and a big warehouse style grocery. We found that there is a chicken ranch next door to our Camp. Do these birds go to sleep at nite?
