Best Rechargeable Battery Chargers in the UK

All of those people in charge of advertisement at Duracell did not choose a racing rabbit as their mascot at random, of course. The company has been always known for making the kind of batteries and chargers that last longer and charge much faster than the majority of their competitors. The Duracell CEF15UK carries that tradition on featuring the Duracell Hi-Speed Expert Battery Charger that requires literally no more than 5 minutes of charge providing you with up to 4 hours of use. And if you wish to charge them up entirely, it will take measly 15 minutes to charge two AA batteries making it arguably one of the fastest chargers out there. On top of that, even though the model comes with 4 AA Duracell rechargeable batteries, the device is capable of powering up all kinds of AA and AAA rechargeable batteries. After it is done completely charging all of the batteries up, the charger will automatically turn off in order to prevent it from overheating. The trickle charge current maintains the batteries’ power so they do not discharge on their own after the charger stops operating.

As important as speed can be, when you're dealing with power and electricity, one of the first things you have to make sure of is that the device is completely safe and secure before you decide to actually acquire one. Fortunately, professionals at Duracell have been in this business for a long time, so they know what they're doing when it comes to that aspect as well. The device comes with up to 10 safety features including but not limited to the protection against over and low voltage or short circuits, protection against charging non-rechargeable batteries and reverse polarity. A cell cooling system delivers air around the cell utilising a fan in order to prevent it from overheating. On top of that, the charger has been rigorously tested against drop, vibration, and shock stress and is designed to withstand virtually any kind of physical and electrical damage. Although there's little to no chance you are actually going to need it, the company distributes this Duracell Expert Charger with a 15-year guarantee, so you won't have to worry about purchasing a different charger for the longest time. All in all, if you're looking for a device that won't waste your time and will charge your batteries as fast as possible, the Duracell CEF15UK is the fast rechargeable battery charger that you ought to look out for.

Youshiko YC4000 comes equipped with an LCD screen that is divided into four separate parts, one for each battery slot. You can apply the model's multiple modes individually as well as together.

The charge/discharge modes will let you quickly and effectively recharge/empty any battery. Using the latter, you'll be able to remove the memory effect that plagues older batteries.

Then, there's the refresh mode. This mode refreshes your rechargeable battery to its maximum capacity by charging and discharging the battery repeatedly until no further increase in the capacity is estimated.

Last but not least, there's the test mode that lets you check the rechargeable battery's capacity in mAh/Ah.

The model has no issues with any and all AA, AAA / Ni-MH, Ni-Cd rechargeable battery with maximum capacity capping at 3000 mAh.

The model's safety mechanisms are nothing new. You have the usual overheat and overcharge protection. These work alright. At the same time, the housing usually starts to heat up after some time. The temperature remains acceptable though.

A nice little touch that we don't always see in these battery chargers is a USB port next to the 12V input that you can use to charge mobile devices. Plus, the model is able to work with your cigarette lighter plug. Just keep in mind that the necessary car adapter is not included in the package, so you'll have to purchase it separately.

Bottom line, Youshiko YC4000 is as good as rechargeable battery chargers get within this price bracket. The model's functional, effective, safe, and practical. It doesn't discriminate and is able to work with most batteries. Plus, the plastic housing is surprisingly robust.

As you might know, nickel cadmium batteries (NiCd) need to be discharged completely before recharging as the frequent partial discharging leads to the “memory effect” which makes full charge no longer available. NiMH batteries are basically considered to be more tolerant to this issue, however, it's better to provide their complete discharge as well, since such approach ensures longer service life. For this purpose, the EBL Universal Battery Charger has the discharge function. To activate this mode, just press a special button. Another very useful feature is that the model comes with a large and clear display allowing you to get all data about the recharging process.

To get the most out of your NiMH rechargeable battery cells, you need to completely discharge and recharge them again 4–6 times. These simple actions will allow you to maximize batteries' performance. The number of discharge/charge cycles varies depending on the manufacturing process.

Rechargeable batteries may differ from your regular ones but there is at least one thing that does not separate them and that would be the fact that there are many different types of rechargeable batteries and a variety of different versions between those types. One of the most alluring things about the BEEWAY PRO D4 is that is capable of identifying and recharging virtually every single type and version of cylindrical batteries, meaning that you won't have to bother with purchasing another charger if some of your batteries happen to be somewhat or entirely different from the other ones. Be it lithium-ion batteries (26650, 22650, 18650, 17670, 18490, 17500, 18350, 16340(RCR123), 14500, 10440), Ni-MH and Ni-Cd (AA, AAA, AAAA, C) ones or LiFePO4 types, you can rest assured knowing that this device will be able to handle them all. On top of that, this product is even compatible with small capacity batteries, which is something that very few models out there could boast. Additionally, the device is capable of charging four different batteries at the same time and all of the 4 battery slots monitors and charges independently.

Another thing that makes the BEEWAY PRO D4 so attractive is the fact that despite being so stacked with features and functions, the device is incredibly easy to operate. There are a couple of handy buttons located on each side of the model that will provide you with an opportunity to easily select the specific battery types and charging parameters. The device features an integrated LCD screen that clearly displays charging parameters and progress. And if you don't feel like doing this job yourself, you're in luck since the impressive and technologically advanced circuitry of this model can detect the battery type and status on its own before entering the automatic charge mode (CC, CV, dV/dt). Moreover, it is also capable of automatically detecting the battery's power status and selecting the appropriate voltage. Just like the majority of top chargers out there, the device stops on its own when the charging is complete without the user having to do it manually. But on top of that, it also comes with an over-charge prevention feature that will do wonders in terms of protecting the batteries from shortening their own lifespan. So if you don't feel like dealing with subpar products and having to purchase an array of additional chargers, get the BEEWAY PRO D4. This professional device will be able to handle any type of battery and features the kind of functions you didn't even know you needed before acquiring this top-notch model.

As we've mentioned above, this battery recharger can be used with batteries of various capacities. To charge AAA batteries, it takes 3–3.5 hours for 1800–2000 mAh, 3.5–4 hours for 2100–2300 mAh, 4–4.5 hours for 2300–2500 mAh. To charge AAA alternatives, the charger requires 2–2.5 hours for 700-800 mAh, 3–3.5 hours for 900-1200 mAh. As you can see, the charging unit really does well! You won't wait too long for your batteries to be completely charged. Another distinctive feature is a USB port that allows charging mobile devices as well. It's particularly useful when no sufficient number of power outlets are available.

Taking into account the capability of the device to charge smartphones and tablets, we feel it necessary to remind you about safety precautions. Make sure not to overheat the batteries. High temperature is the worst enemy of lithium-ion batteries, so, never expose the smartphone to direct sunlight. Likewise, don’t leave your gadgets near heating appliances. The maximum permissible ambient temperatures should be within the range of 40°F to 122°F.
