How long does it take to charge a NiMH battery?

This type of charger can fully charge NiMH batteries, but it might take a very long time to do so. It's possible that an old NiCd charger could take as long as 48 hours to fully charge new high capacity NiMH batteries! Click to see full answer.

Can a Ni-MH battery be trickle charged?

A Ni-MH battery should never be "trickle charged" like Ni-Cad batteries were. So a Ni-MH battery must have the charging turned off when it is fully charged which is usually done with a battery charger IC. How do you know when it is fully charged?

Can NiMH batteries be charged with a NiCad charger?

NiMH cells cannot be charged with a NiCd charger as end of charge detection will not work. Charge at room temperature: NiMH cells do not like being charged at low or high temperatures. Check cell temperature : If an NiMH cell becomes hot then the charging should be terminated.

Are NiCd and NiMH interchangeable?

To some degree, Nickel Metal Hydride (NiMH) is interchangeable with Nickel Cadmium (NiCd) — with caveats. The issues related to replacing NiCd with NiMH are the charge methods, the discharge characteristics (specifically rate capability) and then the effect of both on cycle life.Oct 21, 2008

Will a Dewalt DW9116 charge NiMH batteries?

Product Description. The DEWALT DW9116 Battery Charger is as versaltile as the tools we make. You can charge almost all DEWALT 7.2-Volt to 18-Volt Ni-Cad or NiMH batteriy packs (except Univolt batteries.)

Can I use any charger for NiMH batteries?

Any brand of NiMH rechargeable battery can be used in any battery charger suitable for NiMH batteries – as long as the size is compatible. However we do recommend you use reputable, well-known brands as there are some batteries and chargers of questionable quality on the market.

Can you use the same charger for NiCd and NiMH batteries?

A NiMH in a NiCd charger would overheat, but a NiCd in a NiMH charger functions well. Modern chargers accommodate both battery systems.May 30, 2018

What type of battery can replace a Nicad battery?

Nickel Metal Hydride (Ni-MH) batteries are the cadmium-free replacement for NiCad. They are less affected by the memory effect than NiCd and thus require less maintenance and conditioning.

What does a flashing red light mean on a Dewalt battery charger?

The lights of a Dewalt charger will illuminate when you connect a battery pack. The red light will blink if the battery is charging. The green light will come on once the battery is fully charged. You may even see the yellow light if the battery is too hot.

What is the best way to charge NiMH batteries?

Charging Considerations for NiMH Batteries?
  1. Trickle Charging is the safest method you can charge your battery. To do so, ensure you are charging at the lowest possible rate that will keep your overall charge time BELOW 20 hours and remove your battery at that point. ...
  2. Do not overcharge NiMH batteries.

What's the difference between NiCd and NiMH batteries?

Nickel-metal hydride (NIMH) batteries have a higher capacity than nickel-cadmium (NICAD) batteries, which means that they can generally power your device for longer. They also don't suffer from the same memory effect, so they won't “forget” the ability to achieve a full charge over time.Mar 9, 2017

Does it matter what charger I use for rechargeable batteries?

Pick the right method. You should always charge rechargeable batteries in the device it's used in, the charger it came with or a charger recommended by the manufacturer. Chargers are designed for specific battery types; mixing chargers and batteries could result in unexpected problems.

How long does it take for a Ni-MH battery to charge?

a Ni-MH battery the same size and weight of an old Ni-cad battery has about 4 times the capacity so it will take 4 times as long to chrge with the same charger. A Ni-MH battery should never be "trickle charged" like Ni-Cad batteries were. So a Ni-MH battery must have the charging turned off when it is fully charged which is usually done ...

Why is the lifespan of a NiMH pack lower?

You'll get drastically less torque due to the limited current sourcing ability of NiMH over Nicad, and lifespan from the larger pack will actually be lower overall because of it's internal resistance under load and the damage the heat in the cell will cause.

Does a Ni-MH cell kick?

No "kick". If your Ni-MH cell has a charge that lasts for the same duration as a Ni-Cad cell then the charger is simply a timer that charges both types of cells with the same current. A Ni-Cad cell actually gets cooler as it charges. A Ni-MH cell warms a little as it charges.

Is Eveready a ni-MH battery?

audioguru said: Eveready is now called Energizer. They have a Ni-MH Battery Applications Manual on Energizer's website but it is 11 years old. In those days a Ni-MH cell had a capacity that was only 40% more than a Ni-Cad cell but recently their capacity is 4 times more.

How Batteries Work

Batteries are electrochemical electron storage devices. In a charged battery, the negative terminal (anode) of the battery has an excess of negatively charged electrons.

Battery Characteristics

NiCd batteries were the first rechargeable for home electronics. They are still popular in rechargeable hand tools. They have fallen out of favor due to the environmental concerns of battery disposal.

Li-Ion

Li-Ion batteries are currently the state-of-the-art power storage device. They are in just about every personal electronic device and electric car on the market.

What Can Charge What?

When charging the built-in battery of an electronic device the charger provided with the device should be used. The charger is designed to work with circuitry in the device.

Multi-Chemistry Chargers

Several tool companies produce multi-chemistry chargers for their products. DeWalt is one company that produces a smart charger that will charge Li-Ion, NiMH, NiCd battery packs for their products.

What is the difference between a NiMH battery charger and a NiCd battery charger?

The biggest differences are in the charge rate (how fast the charger can charge batteries) and the charge control (how the charge determines when to stop the charge).

What happens if you use a Ni-Cad charger?

1. The charger will only ever part-charge the Ni-Mh batteries - this is the most probable scenario. 2. The charger will over-charge the batteries - low probability of this happening.

How long does it take for a NiMH battery to charge?

It's possible that an old NiCd charger could take as long as 48 hours to fully charge new high capacity NiMH batteries! This type of charger is not likely to damage NiMH batteries unless the batteries are left in the charger for weeks at a time, but it may not be very convenient to use.

Can NiMH batteries get hot?

In this case the risk is that the older charger will overcharge NiMH batteries. This will be apparent if the batteries get very hot during the charge cycle. (It is normal for NiMH batteries to get warm as they become fully charged, especially in a rapid charger).

Can a timer shut off a NiMH battery?

Unfortunately, since NiCd batteries have a much lower capacity than NiMH batteries, the timer is likely to shut off long before the NiMH batteries are fully charged . This won't harm the batteries, but the NiMH batteries won't be fully charged since the timer will have stopped the charge cycle too soon.

Can you overcharge a NiMH battery?

Depending on the type of NiCd charger you have, the older NiCd charger may undercharge NiMH batteries (most likely), it may overcharge them (less likely), or it may charge NiMH batteries properly (but it's not likely to do so automatically and could take a very long time). Let's take a look at the three cases.

Does a charger charge batteries?

The charger will correctly charge the batteries - Very low chance of this happening. The best sort of charger is one of the more expensive types that can auto-detect when the battery is fully charged and switch to trickle charging mode.
