Battery Tender® 15-Watt Solar Tender® Charger with Built-in 3-Step Microprocessor Controller, 0.83?A Output, 12?V DC

No worries with deltran chargers. Have had several and they always work well. This is my first solar charger but seems to be working well and I'm confident will last for years to come.

Shipped early and in great condition.

A top quality product with 'plug and play' wire extensions and fused battery "ring terminal harness" accesories available for easy install. Mounted on a travel trailer roof and wired down thru the refrigerator vent stack. Well worth the $$ to eliminate hassle of removing battery or keeping trailer plugged in to maintain battery charge when not in use. Will also extend expensive battery life by keeping them at full charge all the time. With the quality, built in controller, easy install, and Wal Mart price with free shipping vs. "Camping World" et. al. this was a "no brainer".

Works great on my dump trailer to keep the battery running [This review was collected as part of a promotion.]

Works great a keeping the motorcycle battery at peak power as it often sits idle and would. Very convenient as it needs nothing but sunlight. Recommend getting the ring terminal accessory which provides a convenient way to connect and disconnect the charger. Also the extension cable may be necessary if your sunny location and the device being charged is a good distance away.

Ideal for maintaining rv batteries. Mount on roof and run wire down frig vent stack. No more disconnecting wires or lugging heavy batteries to garage to keep charged! Recommend installing battery disconnect switch to converter panel, if rv doesn't have one, to stop not-in-use power drains. Easy, economical, fix that more than pays for itself in convenience and extended battery life. LOVE IT !

These are the only solar chargers to buy. Deltran is a quality manufacturer. Don't waste your money on anything else.

Working great to keep our RV (@nautiroamer) battery strong between uses!

I use this to keep the batteries in my RV charged while not in use. I would have given 5 stars if the wattage was higher.

The reason they got two stars instead of one is it got here fast Did not charge battery just by a panel and charge controller like we did works great
