Bal-900 lithium battery charger circuit diagram

SOURCE: I lost my battery charger and i need to charge my camera battery

I lost mine too and did a search on ebay found one from hong kong that worked just fine it was cheap too! just search ebay.

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.

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.
