Batteries & Charging

Post by boffo » Feb 4th, '08, 17:28

There is a lot of discussion from time to time about Batteries and charging, here is some technical information if you wish to research in detail.

Best source of straightforward, but very detailed information I have found is:
http://www.solar-electric.com

One Key page is this:
http://www.solar-electric.com/deep_cycl ... ry_faq.htm

Which has really good info on the following topics:
What is a Battery?
Types of Batteries
Battery Lifespan
Starting, Marine, or Deep Cycle?
Deep Cycle Battery as a Starting Battery?
What Batteries are made of
Industrial Batteries (fork lift type)
Sealed Batteries
Battery Size Codes
Gel Cells (and why we don't like them)
AGM Batteries (and why we do like them)
Temperature Effects
Cycles vs Lifespan
Amp Hours - what are they?
Battery Voltages
Battery Charging (Here is where we get into the real meat)
Charge Controllers (for wind/solar)
Mini Factoids - Some small facts about batteries
You can also download a version of the above page as a PDF:
