Battery FAQs from Panasonic |
 |
|
Q: |
Why
can't Nickel-Metal Hydride batteries be used with previous
chargers? |
|
A: |
Each
type of battery has its own characteristics. The way the
temperature rises during charging is different for Ni-Cd and Ni-MH
batteries. Therefore it is necessary to have a new battery
charger that can detect the differences between Ni-Cd and Ni-MH
batteries. |
| |
|
Q: |
Why
are there ventilation holes on the bottom of the Ni-MH battery
packs? |
|
A: |
One of
the characteristics of Ni-MH batteries is that the battery
temperature tends to rise during charging. To prevent a
reduction in battery service life due to high temperatures, it
is necessary to cool the battery during charging. |
| |
|
Q: |
Since there are holes in Ni-MH battery packs, won't they be
damaged if rain falls on them? |
|
A: |
On the
contrary, since there are holes in the case, it's easier to get
water out of the battery. However, like conventional Ni-Cd
batteries, they should not be used in the rain or where they may
be splashed by water. |
| |
|
Q: |
What
happens when Ni-MH batteries are used in cold weather? |
|
A: |
Since
the chemical reactions inside the battery become weaker when the
temperatures are extremely low, the batteries will not be able
to provide their usual performance. (This is a common
characteristic of all batteries.) When using the Ni-MH batteries
at temperatures below + 14ºF (-10ºC), we recommend charging the
batteries for 3-8 minutes to provide the catalyst to activate
the chemical process. This will allow the batteries to provide
their normal performance levels. |

|
Q: |
Will
the power of the product be different when using Ni-MH batteries
and Ni-Cd batteries? |
|
A: |
Technically, No. However Ni-MH batteries provide more stable
power delivery to the end of the usable charge than Ni-Cd
batteries. |
| |
|
Q: |
Are
there any points to be careful of when storing Ni-MH batteries
and Ni-Cd batteries? |
|
A: |
The
properties of Ni-MH batteries and Ni-Cd batteries are different.
To get the best use and logest life from your batteries, you
should store Ni-MH batteries fully charged and should store Ni-Cd
batteries fully discharged. |
