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!

Great multi port charging station! I use it to charge my fishing boat batteries all at once and works great! Just hook it up, and walk away, highly recommend this unit if in need of a multi port charging station.

This 4 bank charger is awesome. I also ordered extension cables so all 3 harley batteries are charging and my seadoo battery.

I have a boat, a side by side and two ride on lawn tractors. Four batteries being taken care of at the same time without having cords everywhere. Great charger and battery maintenance unit for multiple batteries all at the same time

It does come with 4 connectors that are bout 6 ft in length. This was not clear in the description so it does come complete and ready to use. Great product

I'm very happy with this product. I use this for winter storage at the lake. I don't have to worry about the unit resetting if the power goes out.
