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.

• 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.

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.
