First check if the battery is any good,, it maybe that its lived its life and you need to put a new one on the bike,,also check if this battery charger is realy charging the battery up,,the charger may be working but is the charge reaching the battery? to check if there is a drain just hook up a meeter if it reads a big drain when nothing is on then its the alarm using up the power but the charger should keep the battery toped up ok? i keep a solar sell of 2.5 watts hooked up to my bmw all the time and i never have had a flat battery yet!!! a charger may "over cook" the battery and that will kill it off very fast, all it needs is a stand by charge going into it thats only about 50ma 's and a battery's life is only about 2 to 3 years so if its older than this fit a new one to the bike

My 1999 Chrysler LHS battery drained why is this happening


Tons of possibilities here. Corrosion on terminals builds up over time, causing higher resistance for the electricity going back into the battery from the alternator, causing it to charge more slowly. Moisture (or moisture in dirt) on top of the battery can cause a slow discharge between the poles (worse in humid areas). Short circuits (from bare wires, corroded connectors, etc.). Devices such as phone chargers plugged into power outlets that stay on when the key is off (some do, some do not). Interior lights left on. Remember, also, that alternator recharging will typically not take a maintenance free battery to 100% charge once it has been severely discharged. That means that, even though the car may seem to start fine, it may reach the point of turning the engine slowly (or not at all) much more quickly. It will only reach 100% again if trickle charged (with a battery charger). Probably 4 out of 5 of my battery issues have been solved with a good terminal cleaning and an overnight trickle charge, and my batteries rarely last less than 5 years. My truck battery is still going strong at 9 years. Regardless, though, batteries eventually stop charging, even expensive ones. Hope it turns out to be something simple.

Charging the battery


I recommend using the slow (2amp) charge whenever possible. The slower the charge (in general) the better the results) I will recommend that when you are charging the battery, you remove it from the car or at least remove the cables so there is no drain on it. By removing it all together, you eliminate the possibility of damaging it (your car) from charging a damaged battery and all the nasty little things that can happen! I come from old school and although I have heard conflicting stories since, I always place the battery on a couple pieces of wood to keep it up off the ground and to avoid any damage that leaking acid can cause. Always wear rubber gloves and keep the battery away from your skin or anything else you don't want to damage. always wash thoroughly! Please let me know how you made out or if you have more questions. Thanks and good luck!

Battery drains if parked for a couple of weeks, sometimes more.Alternator is charging, last time I went away, I disconnected the battery. Thanks, BWD


all vehicles use a certain amount of power nowadays, its the keep alive memories of the computors , radio for channels and clock etc, although this drain is minimum it will drain the battery over a period of time, just like a cell phone even if you are not using it it stays alive , either get a trickle charger of disconnect the batt , hope this helps

Hi i have a nec i select laptop.. the charger dosent seem to charge the battery.. and the charger wont work without the battery in .... when it chargers the light just flashes as if it is trickle charging...


It may be burned out, do you have a buddy who you can borrow a battery from?If it's flashing something is wrong. It also could be the female part of the jack, that's the most common part to break on laptops and 70% of the time they break off from pulling out the wire or putting stress on the line while it's still plugged in. The only way you can tell is to test the battery first.

Something keeps DRAINING the battery?


If you disconnect the negative battery cable and connect a 12V test light between the battery negative post and the negative battery cable terminal the light will burn if there's a draw. Make sure all electrical consumers are off and all doors closed when doing this draw test. If the light is on start pulling 1 fuse at a time until the light goes out, when it goes out that's the circuit that has the draw. Trace it from there.

New Battery + Possible Parasitic Drain + Weird Problems


Many new batteries will come with bad cells from the factory. If you just purchased this, I would definately try returning it asap. As soon as you get the new one, immediately hook it up to the charger to see if you have the same results. I have heard of others who have gone through two bad (new) batteries before getting a good one.

Discharge Battery


If it is within warranty, have them replace the unit. Are you using a wall charger or a trickle-charger such as the USB Cable? The wall charger is the only way to truly charge it to full.

If you are using a USB charger or other trickle charger, after the device says it is fully charged remove it from the charger for about 2 minutes and then reconnect it. It will then charge (most of) the rest of the way.

If you don't do this, the problems gets worse and worse. After 1 day, the trickle charger may get you up to a 90% charge. After two days, 80%, etc. After a week you'll only be holding half a charge, even though the device is reporting a full charge while on the charger.

Another tip I have found is to perform a soft-reset after removing it from the charger, particularly if it has been plugged in for a long time at full charge (more than an hour or so). It seems like the device doesn't always detect that it has been unplugged and tries to **** down juice as if it were still plugged in. If you have noticed that your device gets pretty hot when the battery drains quickly, this is probably what is happening to you.

You also haven't mentioned the programs that you are using during the day. Some programs, particularly chat clients, will drain the battery in about 5 hours, though obviously you're not using anything like this while in flight mode.

One more thing. You noted that you were told that leaving it on the charger whenever possible is the thing to do. This is incorrect. The more the battery is exercised in this way, the shorter the lifespan of the battery will be. With any mobile device we're all bound to charge it every night, but once it is charged you want to take it off the charger. A battery being fully charged is just as bad as a battery being fully drained, so you want to keep it somewhere in between as much as possible. __________________
If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe
