It is designed as something you can use to recharge your battery pretty quickly then put it your car battery for extended periods so that it won’t go dead. Unlike a trickle charger, it won’t try and keep charging your battery once it’s fully charged. If that’s what you need, then this is a great one. It’s super simple to use. You can even hard-wire it to the battery and leave a tail for plugging it in. I bought this to maintain voltage on the 12V system on my EV. Though our EV is our main car, we don’t drive it much, we seldom drive it far, and sometimes (especially when we go on driving vacations in our other car), it’ll sit for a week or two at a time. EVs have small batteries and a bunch of always-on electronics that just don’t sit well with that. This keeps the car ready in all those long sit conditions. I wish I could just leave my EV plugged into the charger and let it figure out how to keep the battery charged. But as the poem goes, if wishes were horses… well that ain’t the situation. This is. Also, I think that we’ll be using it on our gas car as we’re driving that less and less and may hit that need. This charger solves the angst of Review: It just works. Get this to keep your Hybrid 12V maintained when not driving. - It just works. I have a newer Hybrid vehicle. Generally we won't drive it much in the winter, and lo behold the 12V battery was at ~3V or so after about 10 days outside in the cold. So we battery pack boosted it and drove around. Got it back up to charge. Purchased a Noco5 and it was worthless. Just read it was at 25% no matter what mode it was in. Checked voltage at 12.1V and it still read 25%. Sure enough after a week or so the battery was running to about 6V and I sent the Noco5 back. Enter this little gem. Keeps the 12V maintained, granted it's only been a couple of days now, but put it on at 11.4V and read it again after taking it off today at 12.2V. I will update after winter to see how this holds up but at the moment very pleased that it's as simple as plugging it in. ## Features - Stay Charged: The powerful 3 amp charger provides a full charge to your automotive vehicle’s battery before automatically going into float mode to maintain proper voltage levels without overcharging. 5 amps 12 volt charger and maintainer - Connect and Forget: With a low maintenance design, our universal vehicle charger and maintainer is compact, lightweight, and easy to operate even in small storage space for your convenience. Features 11 total feet of combined reach including 6 ft. AC cord and 5 ft. DC output charging cord - Includes: 3 AMP battery charger, ring terminal and alligator clip combo cable, 5 year manufacturer's warranty, instruction manual, and lifetime customer service - Monitor Power Levels: A solid state two-color LED light indicates the charging status and if the battery voltage drops too far under load, ISM adaptive charging will resume full charger output power. It is UL/CSA, CE and BC approved - Safe and Secure: Spark-proof during lead connection and automatically detects reverse polarity to ensure a correct, locked-in connection before providing power. - Versatility: Compatible with lead-acid, flooded or sealed maintenance free batteries (AGM and gel cell), this charger works with 6 volt and 12 volt batteries with the push of a button ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B016S7NHWQ | | Amperage | 3 A | | Best Sellers Rank | #2,915 in Automotive ( See Top 100 in Automotive ) #22 in Battery Chargers | | Brand | Battery Tender | | Built-In Media | Funnel | | Color | Black | | Connector Type Used on Cable | Ring Terminal and Alligator Clip Combo | | Current Rating | 3 A | | Customer Reviews | 4.7 out of 5 stars 2,351 Reviews | | Global Trade Identification Number | 00734357220209 | | Input Voltage | 120 volts_of_alternating_current | | Item Dimensions D x W x H | 3.4"D x 11.1"W x 9.4"H | | Item Type Name | Battery Chargers | | Item Weight | 1.4 pounds | | Manufacturer | Deltran | | Mfr Part Number | 022-0202-COS | | Model Number | 022-0202-COS | | Number of Items | 1 | | Number of Ports | 1 | | Output Voltage | 12 volts_of_direct_current | | Product Dimensions | 3.4"D x 11.1"W x 9.4"H | | Specification Met | US FCC, UL | | UPC | 734357220209 713002505359 | | Unit Count | 1 Count | | Warranty Description | 5 Year Manufacturer Warranty | ## Product Details - **Brand:** Battery Tender - **Color:** Black - **Item Weight:** 1.4 pounds - **Output Voltage:** 12 volts_of_direct_current - **Product Dimensions:** 3.4"D x 11.1"W x 9.4"H ## Images ![Battery Tender 3 AMP Battery Charger and Maintainer - Automotive Switchable 12V or 6V Smart Automatic for Cars SUVs and Trucks - Lead Acid, AGM, Gel, & Lithium Battery Charger - 022-0202-COS - Image 1](https://m.media-amazon.com/images/I/51ug4zbSnSL.jpg) ![Battery Tender 3 AMP Battery Charger and Maintainer - Automotive Switchable 12V or 6V Smart Automatic for Cars SUVs and Trucks - Lead Acid, AGM, Gel, & Lithium Battery Charger - 022-0202-COS - Image 2](https://m.media-amazon.com/images/I/61bE-etrjrL.jpg) ![Battery Tender 3 AMP Battery Charger and Maintainer - Automotive Switchable 12V or 6V Smart Automatic for Cars SUVs and Trucks - Lead Acid, AGM, Gel, & Lithium Battery Charger - 022-0202-COS - Image 3](https://m.media-amazon.com/images/I/41MAhZT6l7L.jpg) ![Battery Tender 3 AMP Battery Charger and Maintainer - Automotive Switchable 12V or 6V Smart Automatic for Cars SUVs and Trucks - Lead Acid, AGM, Gel, & Lithium Battery Charger - 022-0202-COS - Image 4](https://m.media-amazon.com/images/I/51fpMHg13xL.jpg) ![Battery Tender 3 AMP Battery Charger and Maintainer - Automotive Switchable 12V or 6V Smart Automatic for Cars SUVs and Trucks - Lead Acid, AGM, Gel, & Lithium Battery Charger - 022-0202-COS - Image 5](https://m.media-amazon.com/images/I/81v+YU5t1EL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: How does Axtra 3.6-amp battery charger compare to Battery Tender 3-amp battery charger?** A: The Axtra acts as both a 6-volt and a 12-volt charger. However, it can also provide a constant 3-amp battery tender witch, when set, will provide a continuous charge over a long period of time. The 3-amp battery tender only provides a continuous charge but cannot provide a 6 or 12-volt charge. If you do not have a charger, I would recommend the Axtra as is it can provide both aspects. **Q: I'm using Axtra battery charger to maintain 2 batteries over the winter. Is this Battery Tender reliable as Axtra battery maintainer?** A: My experience with using the battery tender is nothing but good. Pretty much set it and forget it. No problems what so ever. Very easy to use, very well made, very reliable. I would for sure buy another one. **Q: Is this over rated for motorcycles** A: If the battery is rated less than 30 amp hrs, I would say yes. The rule of thumb is the maximum charge rate should not excede 1/10 of the battery's Amp hr rating. E.g. 20 amp hr battery should not be charged at over 2 amps **Q: Planning to connect black to black and red to red pigtail for car battery still inside car. Confused since not sure if that’s grounded. Pls confirm?** A: Yes, Red to Red (positive) and Black to Black (negative) is the correct connection. Why are you worried about ground on a 12 volt car battery? ## Customer Reviews ### ⭐⭐⭐⭐⭐ Simple, easy to use, solves a specific problem that some EV users have. *by M***D on July 2, 2026* This is a battery tender and not a trickle charger.

I didn't expect it to be as large as it is. It works well for attaching it to my 42-year-old pickup truck, which I drive occasionally, keeping it charged and ready to go. I bought a second identical charger for my Diesel truck, but it is 5 Amp. Yes, I recommend this. ## Frequently Bought Together - Battery Tender 3 AMP Battery Charger and Maintainer - Automotive Switchable 12V or 6V Smart Automatic for Cars SUVs and Trucks - Lead Acid, AGM, Gel, & Lithium Battery Charger - 022-0202-COS - 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 - Battery Tender Junior 12V, 750mA Charger and Maintainer: Automatic 12V Powersports for Motorcycle, ATVs, and More - Smarter Than a Trickle Charger - 021-0123 --- ## 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.co.za/products/21017525-battery-tender-3-amp-battery-charger-and-maintainer-automotive-switchable](https://www.desertcart.co.za/products/21017525-battery-tender-3-amp-battery-charger-and-maintainer-automotive-switchable) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-09-04*
