Product Description The Battery Saver 36 Volt 50 Watt Charger and Maintainer features our integrated micro-processor controlled automatic maintaining, automatic PULSE desolator and modular cabling system. This provides a much more efficient experience when dealing with multiple batteries found in a 36 Volt system used in some RVs, Newer Golf Carts, Boats or any other maintaining needs you may have. The power benefit of the 50 Watt model is the ability to charge up multiple batteries if they are connected together in series or in parallel. The advanced computer control will monitor to make sure that no matter the size of the battery, it will be charged safely and efficiently. The modular cabling system is unique to our chargers and maintainers and allows our units to run longer lengths than any other device on the market. Amazon.com The Save A Battery 36-Volt Battery Charger and Maintainer is one of the most versatile battery charging devices on the market. It not only charges batteries quickly, but also maintains and conditions them. This compact unit is highly portable, and the innovative modular cord system makes it easy to connect with virtually any vehicle. Save Time and Money by Keeping Your Battery Charged It's a fact: batteries naturally discharge over time, even when not connected to a vehicle. If you own a classic car, RV, motorcycle, or any other vehicle that isn't used regularly, you may have experienced this first-hand. Not only is it frustrating, but a dead battery also costs you time and money to recharge or replace. The Save A Battery 36-Volt Battery Charger and Maintainer has a 50-Watt output that will charge a dead battery fast. Solid-state microprocessor technology provides the unit with twice the output and efficiency of older chargers that use transformer technology. This means less heat, less energy, and a greener world. Once the battery is charged, the unit switches modes to maintain and monitor optimal performance levels while extending its life by years. Safe and Easy to Set Up and Operate The Save A Battery 36-Volt Battery Charger and Maintainer comes equipped with features to keep you and your vehicle safe, and is a snap to set up and use. It won't cause sparks when you connect it to your vehicle, and will alert you if it has been connected in reverse polarity. Over-current, over-voltage and short-circuit protection are also included. The bright LED bank makes it easy to monitor charging mode, connection status, and overall battery health. The Save A Battery 36-Volt Battery Charger and Maintainer also features an innovative modular cable design that makes it easy to connect to any battery or vehicle. You can choose to connect with the 5-Amp battery terminal lug cable or the alligator clip cable. Even the AC power cable is modular and removable. All cables come with gold-plated connectors that are suited for long cable runs and improved reliability in harsh environments. The bright yellow cable jacket is easy to see, and helps eliminate accidental disconnects. Additional cables (sold separately) are also available with different connection types and longer lengths. What's in the Box? The Save A Battery 36-Volt Battery Charger and Maintainer comes with a 2-foot 5-Amp battery terminal lug cable, a 6-foot alligator clip cable, a 10-foot AC power input cable, and a mounting bracket for permanent wall or vehicle installation.

This little unit does charge my 36-volt golf cart, but wow does it get hot in charging mode. It does cool down when the yellow light is steady to indicate batteries are charged. I took the cover off when it was charging and the two capacitors in the left corner were too hot to touch (ouch!). These components are not heavy enough to handle the amperage the batteries are sucking in charge mode without overheating and I think this is why others have reported their units failing. Anyway, I really like the unit so I added a cooling fan and the unit is now running cooler. The fan is a small cooling fan from an old computer and powered by an old 5 volt power supply from my junk drawer. I experimented with different voltages and the 5 volt ran the quietest. Picture 1 shows the hot areas and the vent holes drilled in the cover. Every other top picket was removed from both sides and all top pickets on the hot end. Picture 2 shows the fan on the cover over the hot section. I used sticky putty to attach it and an old fan grill on top. Picture 3 shows the setup working on my old EZ-GO cart. I've only been using this unit for a month now and I think these old batteries (8 years or so old) are improving. After a short run and sitting for a day they all are at 6.3 volts and I think a couple were at 6.2 when I started. I will update this later in the year if it's still working.JUNE 7,2020 UPDATEIt's still working after 3+ years. I finally replaced the batteries a couple months ago, but feel I got 2 or 3 extra good years out of the old ones before the plates started crumbling. The unit takes a couple days to fully charge the batteries so I'm now using the regular charger first, then the battery saver unit the following day when the cart is idle. I'm still very satisfied with this purchase.
