12V SOLAR PANEL/ CHARGER

I have a battery and LEDs in my wife's small trailer she uses for her business. Small gel-cell battery, mounted the panel to the trailer, keeps the battery fully charged. Ordering two more, one for the lawnmower, the other for an ATV.

I bought one of these to keep my Seadoo battery charged over the off-season. So simple... disconnected positive battery cable, clip on this solar charger, put the seats back on, put the Seadoo cover on, placed the charger on the rear deck of the boat facing the sun on top of the cover... In the Spring the boat fired right up. I did not check the voltage of the obviously charged battery (I will next time), but the boat cranked and started up strong and the first attempt. I will post another review update after the upcomming winter season...

How big is this?
I'm thinking of using it for my scooter and want to make sure I can mount it to the sisybar

The math about 64 hours is true from a zero battery state. Most batteries are never drained this low. If you use 20% of a batteries charge (pretty common) then 20% of 64 is 12.8 or a days worth of sun.

I think the intent of the device is battery storage keeping (trickle charging) and is meant to keep the battery of your RV, snowmobile, ATV, waverunner, whatever kept at top charge. 60-70ma can be bled off by any LA battery through heat without damage to the battery. This setup would seem ideal for this purpose.

I don't understand the other review written about this solar panel. Although I don't own one I don't see how a panel that is only putting out 60-70ma is going to charge a good sized lead acid battery in any less than a week. For example a 4.5Ah SLA that would be 4.5A/0.07A=64hours to charge. Just though I would let you know.
