Super Leisure Batteries - AGM Battery
For those who love to travel when the weather is cooler or during the winter along with their techno gadgets and gismos that use a lot of power, I'd like to recommend AGM Batteries (Absorbent Glass Mat Batteries).
After having re-equipped with carbon fiber AGM batteries, I have been freed from having to find aires/campsites with electricity hook ups or having to carry a generator around. I had struggled for years with all the power-hungry accessories and finally found a wonderful solution.
These batteries were originally developed for military purpose so one can imagine the requirements they must meet. There are a number of advantages that include charging from solar panels when the charge rate is quite low; discharging at a considerably slower rate compared with other types of battery; staying charged at much lower temperature; being resistant to vibration; can be mounted inside the vehicle; and discharging at the rate of up to 3% per month when not being charged, etc.
The drawback are that they are rather pricey and not readily available (at least 2 years ago).
