| During a power outage, which occurs frequently in Florida, I would like to
| use a battery to power some communication gear. Although the battery is
12v
| and not 13.8v, I think that the gear will still work OK (hopefully).
|
| Question 1. I believe that car batteries have a low internal resistance
| because their primary function is to provide a lot of current for a short
| time. There are other 12v large battery types that will last as long as a
| typical car battery. They are designed not to provide peak current, but to
| supply steady state current for a long time.
| For the life of me, I can't remember the name of those type batteries so I
| can't do a google to find a supplier. I hope this is making some sense.
|
| Question 2. Where can I find articles & schematics for a solar cell to
| provide a trickle charge for the aforementioned battery?
|
| Thank you very much.

On question 1: could you be referring to "Deep Cycle" batteries?
