Difference Between NiMH and NiCd

The NiCd is used where long life, high discharge rate and economical price are important. ... The NiCd contains toxic metals and is environmentally unfriendly. Nickel-Metal Hydride (NiMH) — has a higher energy density compared to the NiCd at the expense of reduced cycle life. NiMH contains no toxic metals.

Can I replace a NiCd battery with a Ni MH?

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.

Can you charge a NiMH battery with a Nicad charger?

A NiMH charger can also charge NiCd; a NiCd charger would overcharge NiMH. Do not leave a nickel-based battery in the charger for more than a few days.

Can you use NiMH batteries instead of NiCd in RC cars?

RE: NiMH instead of NiCD? Yes, I do in both my Traxxas Jato 3.3 and my T-Max 3.3. Just make sure that when you charge them you use a compatible charger and not a NiCd charger.

Which rechargeable batteries are best NiMH or NiCd?

Better performance in driving electronics and huge money saving are the two major reasons to buy NiMH (Nickel metal Hydride) rechargeable batteries. They can be charged up to 500-1000 times and last longer than alkaline or NiCd batteries.

Which is better NiCd or Li ion?

Typically, Lithium-ion batteries are smaller and lighter than a NiCad battery. Lithium-ion also two to three times more expensive than NiCad. On the other hand, Lithium-ion has virtually no self-discharge. ... Brushless motors in most Lithium-ion-powered tools make better use of battery power.

Does NiCd battery have memory?

The simple answer is: Technically speaking NiCd batteries do not have a memory effect. ... If a NiCd battery is repeatedly charged after it has only been partially discharged it will develop a lower voltage and a lower capacity.

Should you fully discharge NiMH batteries?

It is significantly better for NimH batteries NOT to discharge them fully before recharging them. NimH life can be enhanced substantially by never discharging them fully on any occasion.

Do NiMH batteries explode?

Generally, the NiMH rechargeable batteries rarely leak, unlike alkaline batteries. However, both alkaline and rechargeable batteries contain electrolytes, which could induce leakage when the batteries are used incorrectly. By this logic, nickel-metal hydride batteries may explode.

How do you maintain a NiMH battery?

Please note that for new NiMH batteries, it is often necessary to cycle them at least three to five times or more before they reach peak performance and capacity. The first several times that you use your NiMH batteries you may find that they run down (discharge) quickly during use.

How long do RC NiMH batteries last?

And the answer is that The NiMH batteries that come stock on most NiMH RC cars are going to give you about 15-20 minutes on a single charge, depending on the mAH and the voltage of the battery in question. This is for the stock batteries though.

How do you test a NiMH RC battery?

The only way to test them is to use them and then watch very carefully for temperature differences between cells after charge and discharge. Just make sure you balance them by cycling at least once before use. If there is a fault it will usually take a few cycles to materialise.

Can I upgrade my RC car battery?

Upgrading your RC car's battery is one of the easiest, cheapest, and effective upgrades you can do. The battery as you know, supplies power for the motor, servo (steering), receiver and ESC.
