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.
Are NiCd and NiMH batteries interchangeable?
A NiMH charger can charge either NiCd or NiMH. NiCd and NiMH batteries are interchangeable in cordless phones because of the type of charger they use.
Can you charge a nickel metal hydride battery with a Nicad charger?
The controler inside charges the battery differently. That's why NiMh chargers can do NiCad. For 2 cents extra they give you the option to charge NiCad in NiMh Chargers.
Do NiMH batteries need a special charger?
Unfortunately charging NiMH nickel metal hydride batteries is not as easy to achieve compared to other types of cell or battery. The NiMH cells, like NiCds require charging using a constant current .
How do you charge a nickel metal hydride battery?
The cheapest way to charge a nickel metal hydride battery is to charge at C/10 or below (10% of the rated capacity per hour) . So a 100 mAH battery would be charged at 10 mA for 15 hours. This method does not require an end-of-charge sensor and ensures a full charge.
What battery is better NiCd or NiMH?
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. ... Finally, NiMH batteries are much better for the environment than their NiCAD battery counterparts.
Which rechargeable batteries are best NiMH or NiCd?
NiMH batteries have replaced nickel cadmium (NiCd) batteries as the preferred cylindrical rechargeable battery. They offer higher energy capacity (up to 50 percent more) than NiCd batteries and avoid the high toxicity of cadmium.
What amp should I charge my NiMH battery at?
High performance battery chargers like the Traxxas EZ-Peak line with a minimum charge rate of 4 amps are recommended to completely charge high-capacity (3000 – 5000 mah) NiMH batteries in one cycle.
How long does it take for NiMH batteries to charge?
| Energizer Recharge Pro Charger Energizer Recharge Value Charger | NiMH rechargeable Battery Size AA, AAA AA, AAA | # of Batteries 2 or 4 2 or 4 | Charging Times 3-5 Hours 5-11 Hours AA ; 5-11 Hours for AAA | Charging Source AC Outlet AC Outlet |

Do NiMH batteries explode?
Generally, the NiMH rechargeable batteries rarely leak, unlike alkaline batteries. ... By this logic, nickel-metal hydride batteries may explode . The principle of explosion is that the air pressure inside an object becomes too large, so the container cannot be contained.
What is the difference between NiCd and NiMH battery chargers?
NiCd are a bit more forgiving than NiMH in charging. They can generally take higher charging currents and are more tolerant of trickle charging, although even most NiCd don't want to be trickle charged long term. The end of charge is trickier to decide with a NiMH. Most NiMH chargers are therefore “smarter”.
What voltage should I discharge NiMH batteries to?
4 Answers. NiMH cells start at about 1.5 V right when fully charged, drop to about 1.2 V most of their discharge life, and are pretty much empty at 900 mV. Stopping there is usually safe. 800 mV is where you definitely want to stop to avoid damage.
What is difference between nickel metal hydride and lithium ion battery?
Lithium-ion batteries are made of carbon and highly reactive lithium, which can store a lot of energy. Nickel metal hydride batteries use hydrogen to store energy , with nickel and another metal (such as titanium) keeping a lid on the hydrogen ions. ... Weight: NiMH batteries are larger and heavier than Li-ion batteries.
Why do NiCad batteries go bad?
According to the author, NiCD batteries fail completely because they're shorted out by “crystal dendrite growth ,” an accretion that can apparently be blasted away with a quick jolt from a welder attached to a high-voltage source.
How long do NiCad batteries last?
The shelf life for nicad batteries is 36 months , according to Panasonic, (formerly Sanyo). Our experience is approximately 18 months. While we've seen nicad batteries that last past 18 months, they usually require many charge/discharge cycles to get it to perform at 80% capacity.
