I need a battery charger - Astar PD-3010 Portable DVD Player

NI-MH batteries a re very different than car batteries and even tho voltage may be similar, you risk destroying your battery, camera or worse, an explosion. Your batter may only need a limited amount of amperage to charge (likely not much more than 1500ma or 1.5 amp) a car battery charger may put out twice or even ten times that much - hence the explosion risk! Also these kind of chargers detect when your battery is full and will quit charging or switch to a maintenance mode. I'm afraid you're pretty much stuck with using the charger meant for it.

Doug, Any 12 volt automotive charger will work for your lawn tractor, the cheaper no frills chargers will work fine.

Car Battery Chargers

Hi there! It sounds like you have our Linx stick vacuum or hand vacuum model. Plug only the charger into an outlet, the blue light on the charger should flash once. If the light on the charger flashes once then the charger is fine. Try resetting the battery by following these quick steps below.

1. Remove the battery from charger or cleaner
2. Unplug the charger
3. Insert the battery into the vacuum and turn the unit on for 30 seconds (even if it has no power)
4. Remove the battery
5. Plug the charger into an outlet, make sure the light on charger blinks blue once.
6. Insert battery into charger

The light should be a solid blue, indicating the battery reset worked. If so, allow the battery to charge for 3-4 hours, completely deplete battery on your next use and re-charge. If the light on the charger is still blinking, your battery will need to be replaced. I have included a link where you may go to purchase a replacement battery if needed. Hope this helps!

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.)

If your bike works when you have the charger connected but doesn't whith the charger disconnected and just the battery then your battery is not charged or you have a bad connection between the battery and ebike.
If the battery charger is showing green then it normally means that charging has stopped charging and there is no current flow to battery. This could be because the battery is fully charged, OR there is an open circuit (broken wire, etc.) between the charger and battery, OR your battery is so flat the voltage is below the low voltage cut-off point of the charger so the charger is not switching on.
You need to check the voltage out of your battery and compare it to the LVC of your charger (should be specified in the user manual), but from what you have described I'd say you need to replace your battery.

need battery charger for robust 18v drill/driver. charger model 9706

I have exactly the same charger with the battery .
my drill is fallen , and it is broken .

You need a new charger. If batteries where bad charger would still light.

The measurements below are for a 12 volt charger or across one battery at a time. In a 24 volt charger or across both batteries at once, double the values.
The charger will not show any output unless connected to a battery. To test the charger, attach the charger to the battery but do not plug in the charger. Connect a meter to the battery and read the voltage (9.8v - 11.6v).
Now plug in the charger. Read the battery again (13.6 - 14.2v).
The voltage must not be higher than 14.8 on the battery or the battery will over-charge - the charger needs service. If the voltage does not come up to 13.2v, the charger is not running. Again, the charger needs service.
Be patient. You can wait ten minutes and measure again. Batteries respond slowly to the charger.

You will need he correct charger, the 24V will destry a very expensive battery.
