Manual / Information for Ridgid Dual-Chemistry Charger R840093 needed


Recommended Posts

Have a R840093 Dual-Chemistry charger and both Ni-Cad and Li-Ion batteries for cordless drills.

Can not find the manual on this site or anywhere on the internet.

Have downloaded a prior charger manual which is similar but has different lights

If someone has a link to or can send me the R840093 manual please post it.

I am not sure what it means when the two leftmost lights are in different states.


When charging it sometimes has the POWER light on steady and the CHARGING FULL light flashing.

At other times both the POWER and CHARGING FULL light will flash together.

What does this mean? Do both of the above conditions indicate charging?

Also it appears that when battery is fully charged both the POWER and CHARGING FULL lights stay on continuously. Is this the case.

Is the charger still trickle charging either the NiCad or LiIon batteries at the end of the charging process.

The older manual I have also says that it may require several cycles to charge a battery.

Will someone who knows or can look up this information please post it.

I can't find much on this charger, only this

Batteries & Chargers
* Power LED: Indicates if the charger is plugged on an energy source
* Evaluate LED: Indicate when the charger is analyzing the battery status
* Defect LED: Blinks when the pack is defective
* Charging LED: Blinks when the battery is charging, stays when the pack is charged. If the battery stays too long on the charger it will blink slowly for indicationg the maintenance charge
* Temperature LED: Blinks when the pack is too hot (120°) or too cold (32°] and need to be cooled / warmed before getting charged

Lith-Ion batteries cannot be trickle charged.

Here is a link for the equvilent charger from AEGs range. It is a direct download link to a PDF file.


At other times both the POWER and CHARGING FULL light will flash together.

What does this mean?

None of what I researched mentioned anything about a flashing power light. The manual I linked to did mention that the power and full charge light would fade when the battery was fully charged and the charger went into standby full mode. could it be you have some kind of power line issues?
