Battery Saver 2365-48 48V 50W Quick Charger and Auto Pulse Maintainer

I purchased this to maintain the charge on an old 48 volt golf car (6x8 volt batteries) that is only rarely used for visitors. The batteries are only in fair condition and it was losing voltage between charges. It is very easy to install and should do the job nicely. I don't know who added the description "quick charger", but do not expect those results on a large battery pack in a golf car. This will not adequately replace a large battery charger, nor is it meant to have that kind of capacity at 1.15 amps per hour. A regular charger charges at 13-17 amps per hour and can take 8 or more hours to charge a golf car to capacity. Just don't expect this to replace a $300-$500 primary charger for this application. If you want a battery maintainer/conditioner to use between primary charges, this is a good choice.

Raven manufacturer has shut down and parts are not usually available. Enter no movement with selector switch in run position. 48VDC battery in the rear of the UTV need attention. Plug the unit into a 120VAC wall socket in your garage. The blue light comes on. Now take two channel locks and gently separate the exposed gray electrical plug. Take the half plug on the left and connect the two alligator clamps. They fit nicely. The unit lights will flash Battery mode and you are charging. Read simple directions. Let it set for 24 hours of more. It is a maintainer-trickle charger. WORKS GREAT>

Why did you pick this product vs others?: Looked like a good product for the price.

OK, for those who know nothing about lead acid batteries and give this a bad review because its "slow", educate your self. This does exactly what it is made to do. Its a trickle charger that WILL extend the life if your battery. Bought mine in January and has works great on my 48v (6x 8v batteries in series) yamaha golf cart. It takes 2-3 days to get batteries back to full charge after draining during use down to about 30%.That is what its supposed to do. Check your water level after each charge. If you don't, you can cook your batteries. Trickle chargers will heat your elements and dissolve the sulfates attached to the lead elements. Keep your connections clean as well. The faster the charge, the less effective it is at keeping your battery at optimum condition and is part of the cause of sulfation thus low life spans. During the winter, you should cycle your system by putting a load on your batteries and recharge them back up. Make sure that you draw the batteries evenly. My only issue I have with this maintainer is that I wish it had a way to put that even load on the batteries to keep cycling / desulfating during the winter. I bought a cheap 48-12V DC to DC converter from Amazon that I can hook my headlights, USB chargers, etc to and create the load on the batteries evenly during the winter and of course, enjoy tunes and bright headlights on my ride.

Keeps your battery in top shape and lasts longer I used mine on my lawn tractor and golf cart

Worked fine when it workd. Failed just after the warranty period. Completely dead. In a low strain environment, charging a mobility scooter. Always in a garage, never exposed to weather, etc. No other electronics failed, no power surges, etc.

This thing is amazing! I got the 48v maintainer and charger for a golf cart i bought and the guy said it needed new batteries that he had left them go dead. I took a gamble on this charger from reading the good reviews. It took about a week to get them back up to voltage but it works and i still use it to charge it. The batteries started out at 6v now stay at 9v i have six 8v batteries. The batteries had bad sulfacation now it broke it up and you can see the plates again. I don't know why they say a quick charger cause its not made that way its a slow charger but has to be so it doesn't cook the batteries. You can't beat the price. This saved me 900 bucks in batteries and does a great job at keeping them equalized.

I have a 12V Save a Battery for my cars and I also purchase them for gifts as I am very confident in their claims. Don't let the plain yellow and black box fool you, this is a well designed and polished garage tool. I bought this 48V version to charge a dead 48V scooter battery pack. This pack was literally at 0V and nothing else would even recognize it as a battery. Now, the funny part: The diagrams on this chinese scooter were unclear and since the pack was registering 0V, I could not tell the polarity as compared to the Save A Battery. So, I took a chance and connected it based on some fuzzy logic. The battery was left for a few days as the LEDs went on and off and the charger brought the pack back from the dead. The next week, I attempted to use the scooter only to find out the breaker was constantly tripping as soon as the pack was connected. After much swearing and testing, I come to find out that the battery was charged in the opposite polarity and is now a -48V battery. Although I certainly don't recommend that anyone use a battery in this configuration, I saw the cells around to work as a +48V on the scooter. This Save a battery brought a zombie back to life. I'm sure it will help your situation.
