Battery Tender Plus 4 Bank Multibank Charger - 5 AMP (1.25 AMPs Per Bank) - Smart 12V Multi Battery Charger and Maintainer for Standard, AGM, and Lithium LiFePO4-022-0148-DL-WH

Good battery tender. It’s larger than I anticipated but works good and nice to charge 4 at a time.

Amazon delivered on their Prime 2 day delivery guarantee! Ordered this on Friday, USPS delivered it today (Sunday)! I had forgotten that USPS DOES have Sunday delivery on certain items. I have a friend that brings me all sorts of medical grade SLA/Gel Cell batteries that are pulls from different hospitals portable X-Ray machines. Around here, they change them out right at 1 year whether or not they need changing. My friend works for a big computer company and manages many of the imaging servers for various hospitals in the Midwest and they give the batteries to him rather than having to pay some company to haul them off to recycle. It would be a shame to send good batteries with lots of life left in them to the recycle plant. We are both Amateur Radio Operators and these batteries are usually either 12 volt, 9 amp hour or 12 volt 17/18 amp hour non-spillable SLA batteries that have anywhere from 4-6 years life still in them and being medical grade they are pretty expensive when new. Most Amateurs that operate portable, on batteries love these to power their portable equipment when out in the field and we are able to sell them at a fraction of the cost of new ones at many of the "Hamfests" (amateur radio gatherings) around the area. This charger is ideal as it will quickly charge the good ones and help locate the occasional bad ones. Being able to charge 4 at a time is essential as we usually get the batteries in case lots - 8 per case for the smaller ones and 4 per case for the 17/18 amp hour ones. For the environmentalists out there, I DO take any bad ones I find to one of the local battery shops that offers free recycling on all rechargeable batteries. I did not order the extension cables with mine as my battery charging station is close to the area I store them in and the included 4 foot cables work just fine for me. For other types of operation I would recommend the extensions. Would I buy this again? Yes. Would I recommend it to others? Definitely

Super happy with this Battery Tender unit. 1.25A per bank is perfect for maintenance, switches to float automatically, and the cables are long and thick. Keeps all my seasonal batteries topped off with zero babysitting. Solid build, easy wall-mount, no heat or noise. Came fast and in perfect shape. Awesome product — highly recommend!

I needed this to maintain a bunch of batteries although I have a few Battery Tenders already. I use them because experience shows me they work and Deltran always stood behind their product when one went south on me while under warranty. This year I took home the 3 boat batteries which were added to the two waverunner batteries and the motorcycle and the summer car. This unit took care of the boat and the summer car and they work great as long as you buy the available entension lines so you can get them all out of your way and into the corners of the garage where you won't trip over everything. One plug for 4 independent units is nice. Easily worth the price if you need to regularly maintain 4 batteries and don't appreciate turning the ignition on next season and only getting silence or that weird clicking sound. This is particularly painful on a boat when you're "ready to go". Jump starting is not an option and what a hassle on the water - rutting around inside the bilge area. Just turn it on and leave it alone. The internal programming takes care of all the rest. TRUE STORY: I used my firt Battery Tender on my 1999 Porsche since new and only this year replaced the battery while having service performed and told it wasn't properly holding the charge - after 13 years. That made me a believer for life. Never have I had a battery last me anywhere close to that - not even half that. New Porsche batteries are $200 +/- installed. I will say that I did check cell fluid level annually and topped off with distilld H2O since it was a non-sealed battery from Germay (Varta?). That is all. Yes it will pay for itself, and eliminate frustration and save money if you use it religiously and I got religion a ways back. Thanks Deltran!!!

Using this to keep multiple vehicle batteries healthy. It has worked well so far. The only gripe I have is that the leads are a little short and wish they were 2-4 ft longer. Otherwise, seems to be working well!

I bought this for our camp. Since we don't live there I pull the boat and jet skis out of the water when we are not there. And since they would sit for long periods of time I was constantly replacing batteries. I have had to buy a battery since buying the battery tender. Very easy to use and install and was made out of quality materials. Slowly charges then batteries but most times will have them back to fill charge withi a night. Unlike typical battery chargers this thing weighs practically nothing and is easy to move around. Definitely worth the value!

**14 years since purchased** Still works like a champ but I've started hearing a slight buzz and high pitched whining when any bank is connected (charging or maintained). Since this is out in my detached shop, I'm not in a hurry to replace it since it still functions properly. But I will be ordering another one to replace this workhorse. ----- **12 years since purchased** This thing hasn't missed a beat. Always connected to 4 batteries 24/7/365 for over a decade and not once has it failed me. The alligator clamps are starting to wear out, which is to be expected but considering I got over a decade of use from the original set, that's not a bad value at all. Being able to buy new alligator clip ends with the quick-disconnect makes replacing them not-a-bother. ------ **Original review*** I have a fleet of 7 company vehicles that only get used a few times per month. I keep 14 spares as well in the garage to have as backups to prevent as little downtime due to battery juice as possible. This little thing works like a champ. I can have a dead battery back to full charge in under 2 days. Once one battery is topped off, I just move the clamps to the next one and keep cycling the batteries every couple of days. This thing has saved me $1000 in new batteries I buy each year, so it's money well spent. I'm thinking about purchasing another 4 bank to decrease the time it takes to top off all my batteries.

This four gang charge is more expensive than buying four separate chargers, so I balked at first. but it is better than having a tangle of outlets adapters, extension cords, etc. It did clean up the look of that area of my shop, and (with extension cables) made it more convenient to keep two dirt bikes and two street bikes charged and ready. As most every other reviewer says, you need the extension cables. They are standard SAE to SAE extension cables. I bought a 4-pack of 12 footers and that length works great for me. I do have a corner of my shop dedicated to motor toys, and park my bikes close to each other, so this works, with plenty of wiggle room. For my setup, I wouldn't need anything longer than that. Right now, the unit sits on the seat of one of the dirt bikes. Might make a shelf for it one day above or below the outlet.
