The system is a 12 volt. The maximum charge rate should be less than 15 volts. The charging system needs to be tested, to see which component is NOT working properly. It could be the alternator, the voltage regulator, or the battery. The test is called a charging system check. Jim Bunting. Toronto.
yes it just takes longer to charge, but check how much Amps (A) your charger gives out and how much Amps your battery can take if the battery has lower Amperage (A), don't do it, otherwise you're fine. <<>> No, the charging unit has to have a higher output that the battery voltage that it is charging. For example, on a 12 volt car battery the charging rate is 13.5 volts.
Rechargeable batteries are generally stored and shipped with no charge. This allows for a longer battery life. Fully charging the battery the first time will give you the best results for maximum charge and battery life.
battery no longer can store a electrical charge, a charging system failure, a parasitic draw,
when you have to keep charging it frequently, as its no longer holding the charge.
The Ammeter is showing higher use that recharge is because if the battery is charged a too high a rate then you end up with what is called a float charge. You can actually over charge a lead acid battery to the point that it will start generating Hydrogen gas. In all essence you are boiling the battery dry when over charging. So to avoid this the voltage regulator controls the charging current going to the battery so the battery is not overcharged and damaged. Batteries given a slow charge will retain the charge better and longer than high current short term charging. It's like giving the battery a deep cycle charge the lower current and slower the charge the better the battery reserve and cold cranking amp level is maintained. Hope that helps
The charging time will depend on how much of a charge was left in the battery and on the charger you use to charge the battery. The more energy you have to put back in it, the longer it will take for a given charger. And some chargers will be able to deliver more current than others. This will result in a higher charging rate, and a lower elapsed time for the charging cycle.
Lower voltage, no, lower amps, yes. I will just take longer to charge the battery.
If your over charging your battery it ruins the battery therefore it will no longer holds a charge like it should. Trust me I killed two batteries before I learned why.
They are all 12 volt. i charge my marine battery for 6 to 8 hrs. on 6 volt. the less voltage with a longer time is best. the faster the charge the more the lead plates in the battery disintegrate. slow and easy for long life of any battery
Could be a variety of reasons: 1) the charging unit has failed; 2) the charging unit is not plugged in to a live outlet; 3) the battery in the phone can no longer accept a charge. Batteries wear out after so many discharge and recharge cycles and have to be replaced eventually. If you have a voltmeter check for voltage output from the charging unit.
A: If you means for a car it would be 13,68 volts minimum. But what is really important is the amperes out of it that is what is needed to charge a battery and that can be as high as 100 200 amperes out of the generator. Once the car has started the battery is no longer necessary to run it the generator and the regulator will just do fine.
Your battery may be to old to even hold a charge. try charging it a little longer and if you have a volt meter ,you should read about 12.5v. if not ,then you need a new battery.
Possible items to consider: - the charger is not plugged in, - the phone battery is old and no longer accepts a charge, - the batteries are installed backwards.
the alternator isn't charging as it shouldthe battery is bad and can't hold a charge any longeryou have an electric fault somewhere which is draining the battery.
If the voltage is the same you can. It will just take a bit longer to charge than a 150 amh charger.
I read that the initial charge should be 4 hours, but no longer, and that all charges after that should be 2-3 hours, but again, no longer. Charging too long will cause the battery to not be able to hold a charge and could even cause it to leak.
If your battery isn't charging, or is taking much longer to charge than it used to - it's time to replace it. Re-chargeable batteries don't last forever, and will eventually need replacing.
Could be an older battery that can't hold a charge any longer Could be loose or corroded battery cables not supplying a sufficient charge from alternator Could be a weak alternator not charging battery Could be excessive parasytic load drain to battery ( a fully charged battery should be able to hold a charge for 21 days of inactivity) Could be a hidden accessory left on draining battery (i.e. trunk light, glove box light, etc.) Could be a defective voltage regulator not opening on engine shut down draining battery.
The same as charging at 60 hertz if you are in a county that runs at 50 hertz and have a charger that runs at 50 hertz.
The most probable reasons are that either the battery will no longer accept a charge, or that the alternator is not charging the battery. Neither is a real big deal. Most alternators cost less than $100 with a half hour labor to install. You can get a battery for between $30 and $75 depending on the quality and length of warranty.
YES you can. the mah is just the battery's capacity. It will actually last longer than your old battery. It will just take longer to charge it. Just make sure that they are the same voltage...
The battery capacity in mAh divided by the output of in mA. For this tank I think it is 1000mAH divided by 250 mA giving me 4 hours to charge. Not about first time charging or if it needs to be longer than 4 hours to charge to compensate for charge lost in the process of charging.
I don't think that charging a cell phone battery every night hurts the battery. It does not matter how long the battery is being charged. The battery is created for specified period of time and then needs to be changed.
Short answer, no. Not so short answer, it depends on the battery's chemistry. In all cases, you're not going to charge it completely no matter the chemistry, but you might charge it anywhere from nothing to ~75% depending on the chemistry and the 6 volt charger's top voltage(It's not 6 volts! If it's a lead charger, you might expect a top voltage of ~6.8 volts). Also, you want to make sure the charger's amperage doesn't exceed the battery's charging current's ability or you might overheat the battery and destroy it. In a longer answer, it is possible to convert a 6 - 7 volt supply to 8-9 volts with a "boost up" converter but that's either going to require buying the device or making it yourself. Even if you we're to do that, you need to make sure the battery's chemistry's safe limits aren't exceeded. NiMH, for example, has a quick downtown in its voltage near the end of its charging, and if the charging isn't cut-off there, the battery will keep absorbing charge until it overheats and explodes. another comment: yes if it fits into the device normally though it would take a little longer to charge
Yes as long as both the 2450 mAh battery and 600 mAh battery have the same voltage. The larger one will just last longer and take longer to charge up (I am assuming these are the solar powered type lights).
