We've all heard that rechargeable batteries are less wasteful and better for the environment and your wallet in the long run. Regardless, it's always a hassle when they run out of juice. Traditional battery chargers can take hours to recharge, which is inconvenient at best and a nightmare when you need them quickly. And, as if being slow wasn't bad enough, many old-school battery chargers are surprisingly bulky, which isn't a problem when using them at home but is a problem when packing them for a weekend getaway or vacation.

In-Depth Reviews

1. SkyRC MC3000 

Important Specifications 

  • Brand: SKYRC

  • Color: Gray

  • Educational Objective: Science

  • Item Weight: 2.76 Pounds

  • Item Dimensions LxWxH: 7.87 x 4.88 x 2.72 inches

Product's highlights

The first on the list is the SkyRC MC3000, which is the most advanced and best charger for round batteries! It supports a wide range of battery chemistries, including NiMH, NiCD Lithium-Ion, Lilo (4.35V), LiFePO4, NiZn, and others. At the same time, this is the most expensive of the bunch. It is also the most powerful charger for cylindrical batteries currently available, with a maximum charge current of 3A for 4 slots.

View on Amazon

Pros

  • A multi-chemistry charger designed to be a one-size-fits-all solution.

  • Smartphone APP with Bluetooth connection for configuring settings through a graphical user interface.

  • Complete manual control

Cons

  • Unsuitable for non-technologists

  • There is no graphical user interface.

2. Powerex MH C9000PRO

Important Specifications 

  • Brand: Powerex

  • Color: Black

  • Product Dimensions: 4.25"D x 4.25"W x 2"H

  • Item Weight: 0.66 Pounds

  • Input Voltage: 240 Volts

Product's highlights

The Powerex MH C9000 PRO appears to be smaller than its predecessor, but this is not at the expense of performance. The only feature missing from this new version is the Cycle mode. Because of the Refresh and Break-in modes, which are also available on the PRO version, this mode isn't really necessary.

It has four distinct channels and a large display that provides you with the precise information you seek. With a few button clicks, you can learn more about your batteries. In addition, the Analyze mode is useful for determining how much capacity your batteries still have. This charger works well with NiMH batteries but not with Lithium-ion batteries.

Pros

  • Small in size

  • Can perform a capacity analysis on your batteries

  • Can recharge batteries to regain some of their capacity?

  • Charge rate, discharge rate, and other manual controls

  • Quick charge with a charge rate of up to 2A

Cons

  • There are no PC link or Bluetooth options for tracking and plotting battery graphs.

3. SkyRC NC2200 

Important Specifications 

  • Brand: SKYRC

  • Color: Black

  • Input Voltage: 240 Volts

Product's highlights

This is essentially the SkyRC MC3000 for non-lithium users. It only sells rechargeable NiMH and NiCD batteries.

The first on this list is the SkyRC NC2200, which, like its brother, is the most advanced NiMH and Nicad charger for round batteries. It can be considered the father of all NiMH chargers when equipped with the optional Bluetooth adapter.

Pros

  • Optional Smartphone APP with Bluetooth connection for configuring settings through a graphical user interface

  • Bluetooth firmware and software updates

  • Complete manual control

Cons

  • Unsuitable for non-technologists

4. Opus BT C3100

Important Specifications 

  • Brand: Opus

  • Color: Black

  • Product Dimensions: 4"D x 7"W x 2"H

  • Input Voltage: 240 Volts

Product's highlights

The 3100 is less than half the price of the SkyRC MC3000 but has just as much to offer. It is capable of charging Lithium-ion batteries ranging in size from 16340 to 20700, as well as AA and AAA rechargeable batteries.

It even has a hidden switch that allows it to charge certain lithium batteries at 4.35V. This is the charger I'm using as a backup for the SkyRC mc3000 right now. My Voltcraft charger failed me, and I gave my Powerex C9000 to my brother.

It has a display that displays the numbers for each bay individually. It also has a Refresh mode that "exercises" NiMH batteries to bring them closer to full capacity.

Pros

  • A multi-chemistry charger designed to be a one-size-fits-all solution.

  • Can perform a capacity analysis on your batteries

  • Internal resistance can be tested

  • Charge and discharge rates can be controlled manually.

Cons

  • There is no PC link to track and plot battery graphs.

5. Opus BT C2400

Important Specifications 

  • Brand: OPUS

  • Battery Cell Composition: NiMH

  • Unit Count: 1 Count

  • Voltage: 12 Volts

  • Reusability: Rechargeable

Product's highlights

The BT C2400 can charge a wide range of chemistries. This Opus BT C2400 is only for NiMH and NiCD batteries. Aside from the low price, it's a good charger, according to HKJ's review (of the slightly older C2000). It has four distinct bays, each with its own display of information. In addition to the standard charge and discharge modes, it has a Refresh mode. The Quick Test mode, which checks the internal resistance, and the Capacity Test mode.

Pros

  • Can perform a capacity analysis on your batteries

  • Can recharge batteries to restore some lost capacity

  • Charge rate, discharge rate, and other manual controls

Cons

  • There is no PC link to track and plot battery graphs.


Frequently Asked Questions

1. Do the charger or the batteries become warm while charging?

It is normal for rechargeable batteries to become slightly warm during the charging process, particularly when using a fast charger with a higher charging current. However, if the batteries or any part of the charger become noticeably hot, stop charging and check for problems with the batteries or the charging unit.

2. Can you use any battery brand with any charger?

In general, yes—as long as the rechargeable battery is the type that the charger is designed for, any brand of battery should work with that charger. Charge batteries of similar types, sizes, and charge levels together whenever possible, especially when using chargers that charge batteries in pairs.

3. Are battery chargers safe to use?

Yes, when used correctly. This means charging only the rechargeable battery types that are supported to ensure they receive the correct voltage and current. Reliable, modern chargers, such as those on this list, also include several safety features, such as "smart charging" functions that cut off power when a battery is detected to be full, damaged, or running too hot. This helps to avoid problems caused by overcharging or overheating batteries.


Conclusion

Tired of slow, clumsy chargers and interminable waiting? Purchase a better charger and charge your batteries quickly.
