Solar Battery Charger

This type of thing -

Trickle charges your car or boat battery, keeping it in charged condition even when it is not used for months at a time!

When a car is not driven for long periods or a boat is not used frequently, the batteries will self-discharge even it is completely disconnected. Batteries naturally drain power, especially in cold conditions. And if allowed to go flat, may never regain their full power.

This 12 volt solar trickle charger is a great solution for maintaining any 12 volt automotive and marine batteries in all four seasons. Just place this device on the dash of our car or on the deck of your boat. Let this solar battery to trickle charge your battery to maintain its charge and extend its life. It is waterproof and will operate under cloudy conditions.

It includes a back-feed diode to prevent the battery from discharging back though the charger. Includes suction cups for mounting to inside car windows and built in LED light to signal when the charge is charging.

Note: Suitable for maintaining charged batteries, not designed for charging flat batteries.

Please be noticed this solar battery output is 1.5W. It could not recharge flat batteries.

While it sounds like a good deal, look at it this way:
With the bigger solar panels the cost per Watt is under 10 dollars.
With this tiny thing the cost per Watt is $46.- !!!!!!

Not much of a bargain, is it?

I have a 8W solar panel on the roof rack to do the battery maintaining. It cost $80.- on special.

Hi V8 - last one of these i saw go on eBay went for $12.50 plus postage $18.

The example i gave was 1.5 w, but they come in 5 w and 13 w as well (for a higher price of course).

Hi Ray

dsb?

SCA?

Is what you have something like i am looking at? What wattage? Is your caravan a deep cycle? I think we need different wattages for the deep cycle and the silly little car batteries.

I want it more for the sedans and the tractor - leave 'em sitting for a couple of weeks in winter and they won't go. They only do low kms, so don't get a good charging at the best of times. My Commodore is sitting looking stupid on the front lawn where we pushed it out of the way, and the bonnet release cable broke so i can't get the battery out to put in on charge. It would be much easier for us mere females to have it work when we need it, than to have to take the battery out and put in on charge overnight.

M/Hen,

I presume SCA stands for Super Cheap Auto but as for dsb???? I don't have a clue either.
Cheers Trevor.

Deep Cycle battery. Super Cheep Autos.
You measure a battery in amp hours. Mine is a 100amp/hr which basically I can draw 1amp for one hour. Batteries are not measured in wattage. Wattage is a measure of power.

My solar panel is 18volt open circuit and charges at .6 amps so it is not high enough to boil the battery but powerfull enough to keep the charge up
