Can you use a NiCad charger on a NiMH battery?
Using a NiCad charger on a NiMH battery may shorten the battery's lifespan, so it is best to avoid doing so if possible. Charging batteries with the wrong type of charger can damage them, so it is important to be careful when charging your batteries.
Can You overcharge a Ni-Cd battery?
The Ni-Cd battery charger is a Uniross model KB 8 with an output of 140mA so probably not overcharging the NiMH 2500mA capacity batteries. Just need a day or 2 to charge them.
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?
Are NiCd and NiMH interchangeable?
Will a Dewalt DW9116 charge NiMH batteries?
Can I use any charger for NiMH batteries?
Can you use the same charger for NiCd and NiMH batteries?
What type of battery can replace a Nicad battery?
What does a flashing red light mean on a Dewalt battery charger?
What is the best way to charge NiMH batteries?
- 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. ...
- Do not overcharge NiMH batteries.
What's the difference between NiCd and NiMH batteries?
Does it matter what charger I use for rechargeable batteries?
Vladimir Vassilevsky Guest
Yes, they did. NiMH batteries are more touchy about charging than NiCd

Agreed. Also, the peak charger for NiMH wouldn't necessarily work well

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.
