Best Car Battery Chargers
Our first review looks at the Battery Tender Plus from Deltran. This is a neat little charger that packs 1.25-amps of power. This might not seem like much, but due to the way this car battery charger functions, it provides the same charging rate as a 3 amp one! The interesting thing about this charger is that it’s revolutionary. It was the first of its kind to instantly switch to a float/maintenance mode where it helps to maintain the battery charge. This feature is common in a lot of chargers around today, but it all started here!
This is a spark-proof battery, and it’s ideal for cars and other automobiles – such as motorcycles or scooters. The charging process contains four stages; initialization, bulk-charge, absorption, and float-charge. Essentially, the charger is initialized, then it starts the bulk-charge rate to take it to 80% fully charged, then it goes into the absorption stage automatically. Here, it enters float-charge where the battery continues to keep the battery fully-charged without causing any overheating or temperature issues.
You’ll know which stage the charger is in thanks to the lights displayed on the front of it. The best thing about this product is that you really don’t have to do anything. It’s all automatic; your only job is connecting it, which is made easier thanks to the two accessories included in the package – battery tender ring terminals and battery tender alligator clips. The Tender Plus works with all lead-acid batteries, along with flooded or sealed maintenance free ones. Also, you get an impressive 10-year warranty with it as well.
- STAY CHARGED: The 1.25 amp charger provides a full charge to your powersports battery before automatically switching to float mode to maintain proper voltage levels without overcharging the battery
- EASY, FAST CHARGING: A low maintenance design to be quick and easy to use even in small storage spaces, our powersport charger and maintainer charges as fast or faster than any 3 amp charger available
- EXTENDED BATTERY LIFE: Compatible with lead-acid, flooded, and sealed maintenance free batteries (AGM and gel cell) and ideal for use in long term storage to provide and maintain an optimal charge
- MONITOR POWER LEVELS: Solid state two-color LED light indicates the state of the charge and if the battery voltage drops too far under load, ISM adaptive charging will resume full charger output power
- SAFE AND SECURE: Our battery charger and maintainer is spark-proof during lead connection and automatically detects reverse polarity to ensure a correct, locked-in connection before providing power

The last of our car battery charger reviews takes us to this smart offering from Ampeak. Practically speaking, it’s a nicely compact size with an ergonomic handle. So, it’s easy for you to carry around and store in your car/garage, which is always an advantage. It’s designed to work with a 12V car battery, so don’t try and use it on a 24V one! There is so much technology packed into this battery charger, making it one of the most advanced options on the market.
It’s fully automatic, so it charges your battery and switches between different modes for you. This is thanks to a Smart Detect System that identifies when the battery is fully charged, when the voltage is low, when it needs to start charging, and so on.

Here, it can alter the charging cycle, providing a far quicker charging time than a lot of other products out there.
Naturally, there are safety features built in to prevent things like overheating or short-circuiting. An internal fuse protects the battery and charger, so you don’t have issues with too much voltage running through both, causing them to break. A double layer aluminum radiator helps disperse heat around the charger, which stops it from overheating while also allowing it to charge more efficiently.

7. TACKLIFE T8
For something so small, this little item sure does pack a punch! It is incredible that such a small item can provide so much power and at such an incredible price. Even in the severe cold weather and after parking a car on the street for a couple of days, this little wonder was able to jump-start the battery and get the car going with no trouble at all. From looking at the product, you wouldn’t think that it would be capable of giving so much power, but it gets the job done the first time without so much as a hiccup.
Typically after one charge, your battery is still going to have around 97% left if it has been charged to the max. This means that you could do this plenty of times without even having to charge it up, which is handy if you are wanting to keep it in the car with you throughout the week. The only thing that you might find is that packing all the leads up can be a little bit of a nightmare as getting them to fit back isn’t the easiest task. But, this is a small price to pay for such an excellent product.
It is simple to use, so you aren’t going to have any issues figuring out what you should be doing with it at any given time. There is a simple on/off switch to start and stop the device, which isn’t difficult to locate. You can also use this charger to charge your phone if necessary and other devices as and when needed. This makes it a handy thing to have around, either in your car or in your home, in case of emergencies. It is well worth the money that you pay, with plenty of benefits that are not in the least bit matched by the one downside we could think of.
- POWERFUL BUT COMPACT: With 800 amps peak current, the Tacklife T8 can jump start 12V cars, SUVs, trucks or vans up to 30 times on a full charge (charging takes 4.5 hours). It’s a compact power bank (18000mAh capacity), can charge your phone with dual USB ports (one is a 5v/9v Quick Charge) and can power your other car accessories using a 12V 10A DC port.
- LONG-LASTING STANDBY TIME: Unlike other car jump starters, you can manually turn the Tacklife T8 ‘OFF’ to slow down the battery's self-discharge – allowing to the T8 to hold its charge for up to 12 months while not in use. (Please remember to turn ‘ON’ before charging or it will not charge.)
- USER-FRIENDLY EXTRAS: Not just a car battery charger, the T8 comes equipped with super bright LEDs functioning as an emergency flashlight. The red light can function as a traffic hazard warning signal in the event of an accident. The T8 is a multifunctional life-saver with a strobe, SOS signal and built-in Compass. The digital LCD screen clearly displays remaining battery life.
- WELL-DESIGNED: The unique design of the Tacklife T8 car jumper is bold but easy to handle. The specially designed indicator notifies you of incorrect use with an audible buzz and flashing lights. The full metal clamps are built to last and are ergonomically designed to be easy to open.
- WHAT’S INCLUDED: TACKLIFE T8 jump starter, smart jumper cables, wall charger, car charger, USB cable, cigarette lighter socket adapter, user manual and 2 year warranty. Our after-sales customer service is available any time. Please feel free to contact us for help
One of the biggest bonuses of this product is that it has a reconditioning feature, which helps you extend the battery life. You can expect your vehicle to start within around 90 seconds of hooking up this product and switching it on, so you aren’t going to have to sit around and wait while your battery recharges. Also, another feature that you will find on this product is that there is an easy to understand display that tells you when the battery needs charging and has other easy to use icons to make use of this product as simple as possible.
However, one of the biggest issues that has been found with this product is that it is not working the way it should after a couple of uses. While the first few uses work well and do exactly what it says on the tin, after this, the unit stops working in a way that is expected. This would point to some less than adequate manufacturing, and as it is a variety of people who have experienced this issue, we are not hesitant to say that it probably isn’t a fluke. While it might only be $60, it is certainly not worth it if you are having to replace the batteries you have been charging as they no longer work correctly.
Another issue with this product is that it is a little more complex than it first appears. For example, when the battery is fully charged, it comes up with FLO, which indicates that the battery is full, and the product is now trying to maintain that high percentage. However, in some instances, the battery has been dead, and this has been an error.
- 15 amp bench battery charger maintains and charges any AGM, GEL, or WET automotive or marine 12V battery
- Fully automatic high frequency charging delivers 3 stage charging, automatically switching from fast charge, to top-off, to trickle charge
- Battery reconditioning feature helps extend battery life; 40 amp engine start helps start your vehicle in about 90 seconds
- Equipped with reverse polarity protection; LCD screen displays charging status and battery status with easy to understand icons
- Features a patented alternator check which indicates if the alternator is maintaining battery level; ETL Certified for performance and safety
The first thing that we have got to look at with this product is the price. At the low price of $36, you wouldn’t be expecting miracles from this product. But, you should because not only is it one of the most affordable items on the list, it is worth every single penny that you pay and more. It outshines the others on the market that are supposed to be of a higher quality, and there isn’t even a comparison when it comes to the price.
This is a fairly simple product. It is small and easy to use, so everyone can make this investment knowing that they will be able to operate it. The only thing that you do need to watch out for is the fact that the sheet that has the instructions on it does not make clear the difference between the flashing LED’s and the steady ones. However, even though this is the case, it does become very clear to the user within a few minutes of using. As such, it is still a product that is easy to use and doesn’t cause the user much hassle.
Like most others on the market, this battery can be used not only to charge your car battery but other devices as well. The battery life is excellent and will last you a good while before you are going to need to think about charging it. But, if you are going to use it often, then the best thing you can do is make sure it is charged up at all times.
Also, this product does not get hot like some of the others that it is competing with. It does get a little warm to the touch, but nothing that is going to scald you or make it impossible to touch. This is a big bonus as you don’t want to burn yourself with you are disconnecting the product.
