Top Best Battery Charger Reviews
Let’s look at some of the best 5 and get into their details!
#1. Battery Tender Plus Charger and Maintainer.
Battery Tender is a prominent name that frequently makes an appearance in this lineup. Their dominance in the battery maintainer market is undeniable. In fact, their brand is practically synonymous with the charger style itself. If you were to walk into any automotive parts store and ask for a “Battery Tender,” you’d be handed their latest float charger from stock.

This speaks volumes about the quality of their products, including their most basic unit, the Battery Tender Junior. The Battery Tender Junior is a reliable choice, even though it exclusively caters to 12v conventional batteries and boasts a somewhat chunky wall wart design.
However, when it comes to user-friendliness, it stands unchallenged. Just plug it in – there’s no need to fiddle with buttons, and the built-in protection ensures your battery remains safe from harm. If you intend to leave it connected for the long term, it comes equipped with permanent leads that can be affixed to the battery terminals.
For those with multiple vehicles in their possession, investing in several of these budget-friendly units is an excellent choice. They prove to be a more cost-effective solution compared to purchasing a multi-station unit like the 4-bank Tender featured elsewhere on this list. Some users have reported that their Battery Tender Juniors, which have been in service for up to eight years, continue to function flawlessly.
#2. NOCO GENIUS1, 1-Amp Fully-Automatic Smart Charger.
NOCO consistently delivers excellent products, and the Genius1 is no exception to this trend. What sets it apart is its remarkable versatility. It boasts the ability to automatically detect your battery type, select the appropriate charging mode, and even revive batteries that seem beyond hope. But here’s the real highlight – the Genius1 is rated for virtually any battery.

Whether you’re dealing with a vintage 6-volt ’65 Beetle, a marine battery powering a hovercraft, or a gel cell on a 3-wheeler, it’s a straightforward process: just connect it and plug it in. What’s more, it accommodates unusual and one-off applications through its “force” mode, enabling it to charge regardless of what it initially detects.
Now, it’s worth noting that the Genius1 operates at a slightly slower pace. With only one amp of charging capacity, it won’t match the speed of larger units like the Tender Plus. However, this isn’t a problem if your primary objective is battery maintenance, and you don’t rely on it for rapid charging.
#3. NOCO Genius Battery Charger and Maintainer.
NOCO has leveraged cutting-edge and top-tier technologies to craft the Genius-3500, a truly advanced and secure battery charger. This 3.5 AMP powerhouse excels at charging lithium-ion batteries of up to 120AH, as well as 6-Volt and 12-Volt lead-acid batteries. Its proficiency extends to a wide array of applications, including marine, RV, automotive, lawn and garden, power-sport, and deep-cycle batteries.

One standout feature is its ability to expedite charging, delivering twice the speed compared to conventional chargers. Moreover, it possesses the unique capability to aid in the restoration of damaged batteries and is tailored for use in micro-hybrid vehicles equipped with a CANBUS electrical system.
The Genius-3500 is designed for portability, with external mounting holes and a rubberized base to prevent scratches and ensure a secure grip on slippery surfaces. An intuitive LED indicator offers visual feedback on the charging status, providing comprehensive diagnostic information even in maintenance mode.
This charger is compatible with 120-volt electrical systems operating at a frequency of 50-60 HZ. It comes equipped with both integrated eyelet terminals and X-connect battery clamps for versatile use. To further instill confidence in their product, the company backs it with a generous 5-year warranty, allowing you to enjoy peace of mind.
#4. Battery Tender 4-Bank: 12V, 1.25 Amp Battery Charger.
Yes, it’s another Battery Tender, and our previous assertion about their prominence in the market still holds true. The Tender Plus, however, offers a different proposition. While it is pricier than the Junior and lacks extra features, it has its own unique advantages. This charger is not compact, doesn’t feature a sleek LCD screen like the Optima, and isn’t suitable for unconventional batteries. It’s essentially a modest box adorned with a set of indicator lights.

But what the Tender Plus can do is impressive. It’s a set-it-and-forget-it kind of charger with automatic maintenance capabilities. Unlike wall wart-style float chargers, it can be discreetly tucked away within the engine compartment. Speed is another of its strengths. If you’re dealing with a depleted battery, the Tender Plus can swiftly bring it back to a 12-volt charge, outpacing most other options on this list.
This feature is especially valuable when you’re uncertain about the state of your battery. With this unit connected, you can rest assured that you’ll have ample power to start your vehicle in just a few hours, even if the battery was in worse shape than you originally thought.
#5. NOCO Genius G7200 12V/24V 7.2 Amp Battery Charger and Maintainer.
The NOCO Genius certainly lives up to its name – it’s a true genius in its own right. Pardon the playful remark, but the capabilities of this device are genuinely remarkable. It possesses the intelligence to revive dead batteries by simply plugging them in, and it’s equipped with a plethora of safety features to ensure your well-being and safeguard the battery. The Genius boasts automatic battery type detection, a feat made possible by a multitude of embedded miniature computers – hence the “genius” moniker.

The design of this charger is both functional and appealing. It strikes a balance between compactness and convenience, featuring long leads and a power cord instead of a bulkier wall brick, making it slightly larger than the ultra-compact Tender Junior. Nevertheless, it remains sufficiently small to neatly tuck away in a tool drawer. The inclusion of quick-connect leads for the battery adds to its practicality, allowing you to affix permanent leads to your most important vehicles and easily connect them to the device.
There is one limitation to note: the Genius won’t charge 6-volt batteries. Fortunately, there is another NOCO option on this list that can handle those. However, this version is geared for 24-volt systems, which is especially useful for owners of older diesel tractors or trucks. If you appreciate user-friendly, convenient, and robust systems, getting your hands on one of these is a wise choice.
