Question #1:
I am curious about the
AT-5798 PRO charger. Since it is a rapid charger, won't it
generate heat that will reduce the life of the NiMH batteries? |
Answer #1:
We have tested the ALLTEK™ AT5798 PRO with
all brands and capacities of batteries we currently offer. Not
only did the AT-5798 PRO not cause any heat problems, it charged
each battery flawlessly. Form the AAA 600 mAH to the 8000
mAH D batteries, the AT-5798 PRO charger did an excellent job.
This can be attributed to the constant PULSE charging circuitry
and the advanced microprocessor design. |

Question #2:
What is the most batteries the AT-5798 PRO battery charger will
charge at one time? |
Answer #2:
The AT-5798 PRO battery charger is designed to charge no
more than 6
BATTERIES at a time.
Two 9V
batteries and then any pair - 4 batteries - of AA, AAA, C,
or D size NiMH or NiCD batteries. Attempting to
charge more than 6 batteries will cause severe damage to your
charger. |

Question #3: The
instructions for the AT-5798 PRO, talks about charging and
CONDITIONING. I don't know what conditioning is. Could you please
take a few minutes to explain this or refer me to a place that
does. |
Answer #3:
CONDITIONING is the process
by which a charger such as the AT-5798 PRO can revive or
improve the functioning of rechargeable NiMH or NiCD
batteries -" if needed." Please note the
emphasis on the " if needed." NiMH batteries do not suffer
from the dreaded memory effect as do the NiCD type batteries
and NiMH batteries can be recharged at any given discharge level,
it is not recommended to use the conditioning cycle
constantly when re-charging NiMH batteries unless you feel that
your batteries are not performing as well as they once did.
If you find that this is the case then reconditioning them for the
next 2 or 3 charges usually will improve or return their
performance to previous levels. There is one possible
scenario where we do recommend the use of the conditioning cycle
more often for NiMH batteries. This is in the event
that you are re-charging a set of batteries that are not quite
discharged at the same levels. Let's say you have one
battery that is 10% discharged and one that is 50% discharged.
Since the AT-5798 PRO has two independent charging and
CONDITIONING circuits and will charge and condition 2
batteries at a time, the CONDITIONING process will
discharge both batteries to the same level prior to recharging,
assuring you that both batteries are properly charged at the same
levels.
NiCD batteries on the other hand need to be recharged
only when they are close to or fully discharged or they will
develop a memory effect and their useful life will be greatly
shortened. By memory effect we mean that if you were to get
in to a habit recharging NiCD type batteries when they are
not fully discharged, they will eventually hold less and less
charge and eventually they will not hold a charge at all.
Then in this case by using the CONDITIONING cycle in the
AT-5798 PRO you may be able to reverse the memory effect and
return your NiCD batteries to somewhat of a normal
operation and extend their useful life. |

Question #4:
You say that the
ALLTEK charger will charge any AA, AAA, C, D NiMH batteries
regardless of capacity or brand. Does this mean it will
charge your MAHACELL 3800 mAH 'C' and 8000 mAH 'D' NiMH batteries
completely in one cycle? |
|
Answer #4: Absolutely!
The ALLTEK AT-5798 PRO does not discriminate. |

Question #5:
Is the ALLTEK
AT-5798 PRO considered a "FAST' charger, and if so what kind of
charge times can I expect? |
Answer #5: Yes
it is considered a fast charger. As a reference here is the
approximate charge times for the listed batteries below.

Question #6:
You state that 9V Batteries are
charged at 13mA under manual control. Could you please explain? |
|
Answer #6: The
AT-5798 charges 9V batteries @ 13mA constant rate which is less
than .1C ( 10% ) of most 9V NiMH rechargeable batteries and is
considered a slow trickle type 9V charger. So if you have a
200 mA 9V batteries we would need to leave it in the charger for
at least 23 hours ( 200mA x 1.5 divided by 13mA = 23 Hours ).
So after 23 hours you could remove them from the charger and your
batteries should be fully charged. Please note that at the 13mA
charge rate you can leave your 9V batteries on charge until
needed without any worry of damaging them even while charging
other batteries. |
