How does one determine whether the problem is the battery or the charger?

Put the battery on the charger ang charge it for a couple of hours. Put the battery back on the drill. If the drill runs faster that it used to be then the charger is working and the battery is about dead. If there is no noticeable difference in speed then the charger is bad.

if after 10 minutes nothing happen something wrong with the charger,if is not the original for sure doesn't gonna work,sometimes that happen

This may seem a bit obvious but ensure the battery is inserted in the charger the right way round. Assuming this is not the case, determine if the charger is faulty(if you bought a second battery this will be easy)I have had no issues with mine for the last year..

The way to solve any problem like this is, if possible, to isolate in turn each of the factors which could be causing the problem. In succession, check the outlet; try charging other batteries if you have them; use a voltmeter if you have one to check the voltage in charging hole, and while anything a lot of things can be fixed it's likely not worth the trouble here - buy a new one.

Check that the battery is 1) good, and 2) installed in the correct direction. If it does not turn on automatically when these are correct, then the unit may be faulty.

Without knowing the state of your battery it would be hard to say. Try the recondition button to see if you can get the battery to work, press the large button until recond light is lit. It takes a while to recondition the battery. Modern battery chargers will not charge bad batteries. If you started with a dead battery, then recondition may help. If the battery was okay then you have a bad unit. I would try it on a good battery before sending it back

You would have to use a battery tester or a voltmeter whcih will tell you if there is still a charge on the battery

My best guess is to contact the company. They seem to be very active in gathering consumer support as they e-mailed me twice asking me to rate their product. I gave them two separate reviews, both rating the product as excellent and I am sure they will replace the charger.

The only suggestion I can add is to make sure the charger is working properly. It seems obvious, but it's one of those things we take for granted. It happened to us this spring. The charger's plug had come loose from a power strip. If that's not the problem, use a voltmeter to check the power output of the charger and the health of the battery. If that all checks good,it's either the associated wiring/switches or motor. That would surprise me. My bet is on the battery if you've had it for three years or more.

One or two things could be the problem ,, first make sure all the plugs are plugged in, then it could be the charger its self or it could be the battery I would lean towards the charger.

Two questions: is the charger functioning properly? And, is the battery old and no longer able to be charged?

It needs a new batttery, or the charger is bad.Check the volt output on charger.

If the battery pack isn't powered up then the charger is shot. Start with a drained battery for this test, then test it out under a load after charging.Hope This helps.

Fortunately I have not had this problem. I would suggest attaching it to the charger one more time to see if you can get it to charge. Otherwise I would return it for an exchange. I bought an extra battery and have had no problems with the charging of either one.

How old is your Sea Doo? Put a volt meter on the battery and see if it has 12+ volts, then put it on the charger and see what it shows. Sounds to me like a bad charger or a bad battery. Also check where the charger wires from the connector attach to the battery, they could have come loose or never been attached properly.

Suire you checked that the charger wasn't the problem. I would contact Sena and see about returning the bad unit.

Check all the connections first. Still continues have the battery checked to see if it's holding a charge.
