I am afraid that it will be almost impossible to find the circuit diagram for any Chinese product. The only possible option you may have is if you still have the product manual and they have phone numbers you can call. Sorry my friend.

SOURCE: i just got a hp PB360t digital camera and lithium

This recharger must be for several types of batteries, which is why it this battery seems not to fit in it. I, too, was perplexed until I looked at the icons on the recharger and the icons on the battery. When looking at the recharger with the LED on the left, place the battery in the top right corner. It just fits and will fall out if you nudge it just a bit. HTH.

SOURCE: Recently bought Craftsman Lithium battery & charger that failed.

Sounds like your charger is only for NiCad batteries. With most brands, the new Lithium chargers will also charge the old NiCads, but the old NiCad chargers will not charge the new Lithium batteries. You will be very happy with the lithiums once you are able to fix the problem. As for Craftsman, buy Craftsman hand tools such as wrenches and sockets but I'd look elsewhere for battery powered tools.

SOURCE: Does it harm a Ryobi 18v lithium battery to leave on Charger?

Lithium-Ion batteries require careful charging and temperature monitoring while in the charger. Ryobi's Charging station monitors many functions and shuts off when the battery has gone through a complete charge. This is indicated by a steady Green light. Once the Charge indicator is a steady green the charger stops charging. With any battery It will slowly discharge and I don’t think the Ryobi will maintain a battery that is never removed. For example, if after a complete charge cycle if the battery was left there for 2 years and then you went to use it, it would likely be completely discharged. However if the battery charger is unplugged then plugged back in a new charge sequence would start. I lose power at my house about every 6 months or so. Once power is restored a new cycle would start and the charging cycle begins again.
Hope this helps and have a great day.

SOURCE: Black & Decker LITHIUM CHARGER 14.4v to 18v . 90539541. fits A1518L, HP1884L

could be either one. Have you tried another battery? If not I would recommend taking BOTH in for inspection. They have a scanner that can detect if the battery has a problem. If you need to find a service center close to you go to dewaltservicenet.com and they have a locator. Let me know if you need more assistance.

Can I leave the battery charger plugged in my Dyson dc 44 animal after it is fully charged?


Hi, I have a Dyson DC56 with a lithium battery for about 18 months and I leave it plugged into it's charger when not in use. I do notice the Dyson charger seems to switch off automatically when charged. I don't have any problems so far. It you have a Genuine Dyson Lithium battery and the genuine Dyson charger it should not be a problem. That is because Lithium batteries have very precise requirements for their charging cycles and therefore the correctly designed charger required to make them work safely is a somewhat intelligent design and needs to be of good quality in having to meet those requirements. So use the original Dyson Charger. Also most high current Lithium Batteries will also have a protection circuit built in further increasing safety and reliability. Just don't use cheap cloned Chinese made Lithium chargers, because you will never know if they have been designed or even will operate correctly.
Now if you have old technology Ni Cad (Nickel Cadmium), LA (Lead acid) or NiMH batteries with basic cheap chargers they should not really be left connected to a charger full time.

18 V Ni-Cad charger repair


From what I've seen.....usually when Lithium batteries won't charge it's because they lost too much of there charge. As soon as a Lithium battery shows signs of weakness they should be charged. But to answer your question most chargers do have a fuse soldered to a circuit board so yes it's possible to be a fuse but not usually "simple".

Will the P110 charger charge a lithium ion battery


No, the P110, 18V NiCad battery charger, will not charge a 18V lithium ion battery. You need one of the dual-chemistry chargers. If you have the Ryobi ONE+ batteries, you can get the P117 charger ($30) or a charger with an extra battery (P126) from a store like Home Depot. A 6 battery charger and a 12V in-car charger are also available.

I wish that I had better news for you.

(who has the Ryobi 12V drill and charger, a few of the 4V tools, and a number of the ONE+ 18V devices and chargers. The single chemistry battery charger is not used much any more.)

What Ryobi batteries p103 or p104 will a battery charger that came with my p100 batteries charge? Or will the charger work with these batteries?


If you have a P100 NiCad battery, the charger for that will not charge the new Lithium Ion P103 or P104 batteries. You need a specialised Ryobi Lithium Ion battery charger like this one

Can you charge ryobi lithium batteries in a regular ryobi charger?


NO! Never charge lithium batteries in a charger designed for nickle based batteries like the NiHi your old charger was meant for. Ryobi did design the new Lithium charger to be backwards compatible so you can charge your older 18V NiHi batteries in the Lithium 18V charger.
Also note, NEVER miss-match the voltage, for example, make sure you are not trying to charge 12V batteries in an 18V charger unless the manufacturer has specifically stated that the charger is capable of multiple voltages.

Can you charge a 18v lithium battery in a nicd charger?


Do not try this since the charging circuit for lithium batteries are different than nicad! Improper charging of lithum batteries can cause a fire.

Purchased the two lithium and charger combo about two years ago. I use my Ryobi drill and flashlight in the garage and around the house no where near commercial/professional levels. About three (3)...


How long have these 2 batteries been standing idle without being charged? Lithium ion batteries can still discharge if left for too long. There is a voltage detector which detects whether the cells are too far discharged to be safely charged again and if that occurs the circuit is broken and the batteries will be deffective in the charger.
I have had the same problem with these and other LI batteries. Answer is replace the batteries and then make sure they are given a quick charge on a regular basis. However common advice seems to be that LI's should not be kept fully charged, but just partially charged until needed, then charge them for use, especially if usage is sporadic

Ryobi p103 battery charged but dosen't work.


You need to have the charger tested, if you know that batteries are good then what else could it be. This LIon charger has a logic circuit in it like a computer.
