336 / Model BCR336
For Li-Ion, NiMH, NiCd & Lead Acid Batteries
INTRODUCTION
Thank you for purchasing LENMAR’s OmniSource 336. The model BCR336, will charge virtually all 3.6, 4.8, 6, 7.2, 9.6 or 10 Volt Li-Ion, NiMH, NiCd and
Lead Acid type rechargeable batteries. When recharging NiCd type batteries, the model BCR336 will operate as an AC/DC Battery Charger and Reconditioner
to help avoid developing memory in your battery.
This charger will operate from a standard household AC outlet, or on the road from a 12 Volt cigarette lighter socket. It is a complete, convenient system to
charge and condition almost any of your rechargeable batteries.
Using the charger
Plug the unit into your selected power source
Choose the proper adapter for either 110V household current or 12VDC car cigarette lighter adapter. Plug the proper adapter into the power source and plug
the connector at the other end of the cord into the charger unit.
Adjust the contacts for your battery
The contacts on the charger must be properly adjusted to line up with the contacts on the battery before charging can take place. You must align the two
contacts on the charger to the two contacts on the battery marked “+” and “–“. There may be additional contacts on some batteries, which must not be
connected to. Only connect to the “+” and “-“ contacts on any battery. Connecting to the wrong contacts may damage the battery and/or the charger.
Reversed polarity
Once the battery is placed on the charger, the charger should emit a short beep and begin charging the battery. If the charger beeps continuously, the polarity to
the battery is reversed. To remedy this, slide the switch (labeled S) on the side of the charger to the opposite side. The beeping will stop and the charging will
begin.
The temperature sensor
The temperature sensor is important for the safe charging of your battery, so be sure it is attached to the battery whenever you are charging. Failure to do so
could result in overheating and permanent damage to the battery. The sensor is magnetized and will stick to all battery types except Lead Acid. The sensor may
be left off for this type of battery without harm.
If the battery has Bottom contacts
Open the hinged jaw on the charger to unlock the moveable contacts.
Hold the battery over the charger so you can see both the battery contacts
and the charger contacts at the same time. Move the charger contacts
sideways to set them at the proper distance from each other to match the
contacts on the battery. Set the battery down onto the contacts to test
they are in the correct position. The correct setup allows the battery to
rest against the long fence (marked “D”) and connect with the charger
contacts. This allows for easier alignment of the battery to the charger.
For large batteries or in some circumstances, the “D” fence may need to
be reversed or removed to make more room for the battery. The same is true for the smaller “C” fence. When you are satisfied with the contact locations, close
and latch the hinged jaw to lock the charger contacts into place. Set the battery down on top of the charger and make sure the charger contacts connect with the
battery. Place the magnetic temperature sensor on top of the battery being charged.
Special Instructions For Charging Sharp BT-30N Or Lenmar SBT30 Type Battery:
As shown in diagram 1, open the hinged jaw on the charger to unlock the moveable contacts and move contact “A” as far to the right as it will go. Position
contact “B” so that it is 3/8 inches left from the tip of “A”. Close and lock the hinged jaw. Slide Guide “C” out so that it hangs over the end of the charger by
½ inch. As shown in diagram 2, remove the guide fence “D”. To place the battery onto the charger, hold as shown and align the contacts on the battery to the
contacts on the charger, and lay the battery flat on top of the charger. The charger should emit a short beep and begin charging. If it makes a long continuous
beep, see section titled “Reversed Polarity” above. As shown in diagram 3, place the magnetic temperature sensor on top of the battery (optional).
