But, something happened, and the 1st side stopped, but the 2nd side kept working fine. I reached out to the manufacturer, and they were very helpful, and sent me a replacement unit. The customer service was excellent. They were in contact with me almost daily, asking for pictures, and wanting to know all they could to determine what went wrong. We worked together and I hope they got constant updates from me, as well, and now I have a brand new, replacement unit thanks to their service and dedication. I highly recommend them for their product, and for replacing one that must have had some sort of defect. It's great to know that they warranty their product and how good they were working with me to get me back up and with a new charger that I will be able to use to keep my batteries charged. Kudos to their staff and all they did. Review: What else can I add? *Update, almost 10 years later* - Not much to add to the great reviews so far. This thing is great. I have 2 batteries in my boat and 2 in my diesel truck. I installed the plug-in leads on the boat batteries for easy, semi-permanent, solid connecting installation. The clip leads I'll keep here at the house for the truck since that's a short term need. It's easy, light, compact and does the job well. Just plug it in and go and I don't have to worry about weekly trips up to the boat to switch a big clunky battery charger from battery to battery. When I need to top off the truck batteries (it helps keep them healthy) I'll plug it in here and not have to worry about disconnecting the 1 battery I'm going to charge so the other won't leach off it. I can charge both evenly and not put undo draw on the stronger of the 2. I just wish I would have gotten this thing a long time ago!!! Update 10-7-2019 In 3 months this Tender will be 10 years old!! It hasn't missed a lick and for the last 6-8 years this has been kept on my boat constantly on when it's not in the water. It's connected via the plug in pigtails to 2 Optima's. Optima isn't what Optima used to be (only buy Odyssey anymore which are well worth the price) so this tender has kept them healthy. I pull it off and put it on my truck (2 batteries also) every now and then although with Odyssey Extreme's in it now, it hasn't been necessary. I'd consider mounting this Tender in the boat more permanently for more convenience. FYI, I just noticed the price is exactly what it was in 2010 when I bought mine. I'd have expected them to go up, and still, they'd be more than well worth it!!! 5 Stars isn't enough. ## Features - Solid state two color LED indicates stage of charger; spark proof and reverse polarity protected - Two independent charging stations, each providing 12 volts/1.25 amps, with temperature compensation to ensure optimum charge voltage according to ambient temperature - Complete 3-step charging program (Initialization, Bulk Charge, Float Mode) allows for optimization of battery power, without overcharging - Perfect for all AGM (absorbed glass mat), sealed maintenance free and flooded batteries - 2-year limited warranty ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000NCOKV0 | | Amperage | 1.25 A | | Best Sellers Rank | #3,645 in Automotive ( See Top 100 in Automotive ) #29 in Battery Chargers | | Brand | Battery Tender | | Built-In Media | Deltran BT Plus 2 Bank DL WH 12 Volt | | Color | Black/Green | | Compatible Devices | Controller | | Connector Type Used on Cable | Alligator Clip, Ring Terminal | | Current Rating | 1.25 A | | Customer Reviews | 4.8 out of 5 stars 2,944 Reviews | | Global Trade Identification Number | 00734357216516 | | Input Voltage | 12 volts | | Item Dimensions D x W x H | 8.8"D x 3.5"W x 7"H | | Item Type Name | Batteries & Chargers | | Item Weight | 3.4 pounds | | Manufacturer | Battery Tender | | Mfr Part Number | 022-0165 | | Model Number | 022-0165-DL-WH | | Number of Items | 1 | | Number of Ports | 2 | | Output Voltage | 12 volts_of_direct_current | | Product Dimensions | 8.8"D x 3.5"W x 7"H | | Specification Met | UL | | UPC | 734357216516 | | Unit Count | 2 Count | | Warranty Description | Manufacturer Warranty | ## Product Details - **Brand:** Battery Tender - **Color:** Black/Green - **Item Weight:** 3.4 pounds - **Output Voltage:** 12 volts_of_direct_current - **Product Dimensions:** 8.8"D x 3.5"W x 7"H ## Images ![Battery Tender 2-Bank Battery Charger - Image 1](https://m.media-amazon.com/images/I/71Kyf5Ej4PL.jpg) ## Questions & Answers **Q: Is this charger fully automatic? Plug it in/hook it up and it does the rest? Or do you have to push buttons to select battery type/size/charge rate?** A: This is NOT a charger that I would recommend to bring back a dead battery as it is, in reality, a trickle charger. it will charge slowly and maintain a charge for you automatically. It is specifically for 12V batteries. **Q: Will this unit charge 2 12V batteries in the same amount of time it would take using 2 separate 12V Battery Tenders?** A: I beleve it will. I keep two batteries as backup for my toy hauler. After using them I hook them up and by the nexk day they are charged. I love them. I have two and a couple of singles. **Q: How long are the cables that connect to the batteries? I have a small sports car with a battery in the back and in the front of the car. Do I need extension cables?** A: Each cable is approx 6 1/2 ft long which will give you a width of 13 feet. Hope this helps. **Q: Does it come with quick connect ends as well as the alligator clip ends?** A: yes, read the description of the model you want and it will tell you what is included...i bought extra quick connects and extensions for 6 different vehicles.. great product ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great unit, even greater support staff *by T***S on September 14, 2026* I bought this charger back about 3 months ago, and it worked perfectly.

I was worried that the cords might not be long enough for my application (boat batteries installed 5' apart), but it worked nicely. The only thing that was both a surprise and a disappointment was that the ring terminal option is very small in diameter. Like maybe a 1/4" post diameter max. Unlike their previous choices for alligator clips vs. ring terminals, this doesn't include separate pig-tails for each. Rather, the ring terminal is screwed into the alligator clip and to choose that option you simply remove the alligator clip from its ring terminal mate. In the past they provided separate pig-tails and I find their current design far more limiting due to the small diameter of the ring terminal. Nevertheless, working with the alligator clips works for me (but honestly, I would have preferred to install these pig-tails on the battery's tandem screw posts). Whatever. One thing that they don't tell you is what happens when you unplug it. Well, the device comes up defaulting to lithium (hmmm, strange). The boat has the most basic standard flooded batteries. When you unplug the device it "chooses" the last setting you used so that means you don't have to constantly tell it what battery technology you're using. It would have been a really annoying oversight had they not programmed the charger to do this. Not a fatal flaw but an inconvenience nevertheless. So - NON ISSUE - thanks Deltran for anticipating this. Also, the unit is huge and rather heavy compared to their other products. It's mountable, but for me it's too big to mount in the compartment that would have made the most sense. Long way of saying I'm happy with this and would definitely recommend to friends and family - but with warnings about the size and ring terminal limitations. ## Frequently Bought Together - Battery Tender Plus 2 Bank Multibank Charger - 2.5 AMP (1.25 AMPs Per Bank) - Smart 12V Multi Battery Charger and Maintainer for Standard, AGM, and Lithium LiFePO4-022-0165-DL-WH - Battery Tender 25 Foot Extension SAE Cable - Designed for Use with Battery Tender Chargers - Quick Connect Plugs for Easy Connection to Motorcycle, Cars, ATVs and More - 081-0148-25 - Battery Tender Ring Terminal Harness Accessory Cable - 18 inch Cord Adapter with SAE Quick Disconnect - Easy Quick Convenient for Motorcycles, Cars, ATVs and More - 081-0069-6 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/1721120-battery-tender-2-bank-battery-charger](https://www.desertcart.pt/products/1721120-battery-tender-2-bank-battery-charger) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-10-02*
