Bad contact on battery use multymeter to check if voltage is there if not open the battery pack and see if bad connection exists or try another battery

No its strickly a jump starter not a trickle charger.. you can buy a small power supply in the 250ma range and make a cheap trickle charger.

They have a built in trickle that shuts down after the battery is fully charged, you can leave it forever if you want. We leave ours plugged in overnight. I have one that is always on with a battery in it. Hope this helps.

try another battery in the charger

This behavior is typical of trying to charge a battery that is wither too hot (let it rest for a hour) or one that has done its job and is ready for the battery retirement home. Replace your battery for best results with your Ryobi battery powered tool.

Lithium Ion batteries don't charge the same way ni-cads or ni-mh do. You need a lithium ion specific charger to charge them. (Some chargers do multiple types.)

If the drill has a short in it, then yes, it could short the battery out. Probably in the trigger switch.

SURE. DON'T WORRY IT WILL BE CHARGED

check your pins

It appears that the recoil spring has broken and you will have to pull it apart to replace it

get new battery

I have a feeling that the batteries might be the issue. They might have dead cells or if they got to hot or cold the battery case can swell a little. That will cause the issues you are experiencing. Have A Good Day

Purchaseed Roybi P2102 cordless blower at Home Depot yesterday. Put battery on charger for 12 hours and it would not get past the "test" phase. Called Ryobi customer service 800-860-4050 (got a live person quickly), was told I had two options: take the blower back to HD for refund/exchange OR take it to the Tool Rental or Pro Desk at HD and they can test the charger/battery and can provide a replacement if defective, all FREE of course.

if it is not a rechargable battery it will not charge

I've open the charger and found that Q4 is open. But they have removed the part number from the component so you can't get a replacement.

In most cases 24 HRS

Use a working battery to test it. discharge the battery first, and use the charger to charge it. If fully charger, both is OK.

This depends on the capacity of the battery and the output current of the charger.

please check if the RED LED light is flashing or not. If yes, this battery may defective. If defective, try to repeat the conditions a second time by removing and reinstalling the battery pack. If the LED status repeats a second time, try charging a different battery. If a different battery charger normally, dispose of the defective pack. If a different battery also indicates "Defective", the charger may be defective.

No, please do not do that.
