What is a Ni-MH Battery?
Ni-MH (Nickel-Metal Hydride) batteries are newly developed batteries that do not use cadmium, making them more environmentally friendly than standard Ni-Cd (Nickel-Cadmium) batteries. Also, more electrical elements can be packed into Ni-MH batteries, giving them a larger power source than Ni-Cd batteries.
Advanced Charging Technology
Panasonic Ni-MH batteries have a short, 65-minute charging period. This system was created by Panasonic as a result of our vast experience developing inverter charger technology. With this new charging system, Panasonic has achieved two goals:
- Minimize charging time for the Ni-MH 3.0 Ah high capacity battery pack
- Maximize protection for the battery pack, insuring long battery life
Other facts about the Ni-MH battery 65-minute charging system:
- The charger is four times more temperature sensitive than Ni-Cd-only charging systems, reducing damage caused by a sudden temperature increase
- The battery pack features ventilation holes, which cool the battery during charging
- A double capacity CPU can charge both Ni-HM and Ni-Cd batteries
- Inverter Technology gives the charger a high power output
- The Ni-MH battery pack and Ni-Cd battery pack have similar life cycles (+/- 1,200 charge/discharge cycles)
FAQs
Q: Why can't Ni-MH batteries be used with previous chargers?
A: Each type of battery has its own characteristics, and the way temperature rises during charging differs between Ni-Cd and Ni-MH batteries. Therefore, you need a charger that can tell the difference between the two types of batteries.
Q: Do Ni-MH and Ni-Cd provide different levels of power?
A: Technically, power is the same, although Ni-MH batteries provide more stable power delivery to the end of their charge than Ni-Cd batteries.
Q: Should Ni-MH and Ni-Cd batteries be stored differently?
A: Yes. To get the best usage and longest life from your batteries, Ni-MH should be stored fully charged, and Ni-Cd should be stored fully discharged.
Q: Why are there ventilation holes on the bottom of Ni-MH battery packs? And won't this cause damage if the battery gets wet?
A: Battery temperature tends to rise during charging, and these ventilation holes cool the battery to prevent a reduction in service life. Also, while the holes actually make it easier to get water out of the battery, you should not use them in areas where they are subject to rain or spills.
Q: What happens when Ni-MH batteries are used in cold weather?
A: When temperatures are low, the chemical reactions inside the battery become weaker, thus hindering performance (a common characteristic of all batteries). When using Ni-MH batteries in temperatures below 14¡F (-10¡C), we recommend charging them for 3-8 minutes to provide the catalyst to activate the chemical process. This will most likely allow the batteries to provide their normal performance levels.
