Safety
Read the following user manual carefully before use to prevent damage to the charger and to
protect yourself and others. Keep this user manual so that you can reach it in the future if
necessary.
NOTE
In emergency situations* disconnect the charger from the power supply and locate the nearest
distributor.
* Emergency situations include:
• Smoke escaping the device
• Leak of substance from the device
• Change of shape of the device
• Damage to the housing or components of the device following a fall
1. This device is intended for indoor use only.
2. Attempts to charge other types of cells (alkaline, zinc carbon, lithium or any types of
batteries other than Ni-MH or Ni-CD) may cause personal injury or damage to the device.
3. Protect the device from rain and moisture to prevent electric shock or fire
4. Do not use the device if the plug is damaged
5. In no circumstances should you perform any repairs to the device or the batteries on your
own
6. This device is not intended for use by persons in need of supervision or children
7. Cells may contain hazardous substances and may not be intended as reusable. Contact the
cell manufacturer for information concerning the properties of cells.
Properties and benefits
Congratulations on your purchase of our Product. YOKOHAMA is an intelligent charger intended for
charging up to 4 Ni-MH/Ni-Cd AA/AAA-type batteries. Thanks to the latest microprocessor
technology applied, this functional device guarantees efficient, secure, portable and easy charging.
• Charging 1-4 AA/AAA Ni-MH Ni-CD batteries
The YOKOHAMA charger loads any combination of 1-4 AA/AAA Ni-MH or Ni-Cd batteries.
• Safe charging time
The charger automatically detects the suitable charging time, reducing the current at the
appropriate time. The charger reduces the current after approximately 6, 9 or 12 hours
regardless of the charging time.
• 4 independent charging channels
You can charge any combination of batteries
• 5 charging protection levels
• DC voltage cut
Thanks to the high-sensitivity detector, the device stops charging when it detects that the
batteries are fully charged
• Safe charging time
The device stops charging when the charging time exceeds 15 hours
• Protection against reverse polarity
Electrical circuits protect the device and batteries when the batteries are inserted in reverse
• Protection against overload and short circuit
The YOKOHAMA charger maintains a constant level of voltage throughout the charging cycle
and also protects the charger when attempting to charge the batteries after short circuit.
The indicator flashes in the event of short circuit.
• Detecting damaged and unrechargeable cells*
This feature protects the charger when attempting to charge damaged or unrechargeable
cells.
*Note: Charging cells other than rechargeable can cause fluid to leak out of them
• AC 100-240V mains voltage switch allows to use the charger in multiple countries
• Maintenance charging: when the batteries are fully recharged, the low current will continue
to affect the batteries in order to maintain full charge level by minimizing the loss of
charging through current leakage.
• Low level of current leakage
If the charger is not connected to the power source and the batteries are left in the charger,
they are usually discharged. YOKOHAMA charger minimizes this type of energy loss.
