Cant charge batterys dont know if it is charger the lead or the plug

You have to check four things to check where the issue is.

Wall power
Charging lead
The charger
The phone charging port or battery.

Remove the wall plug and try something know to work.

Change the charging lead for another one that is known to work.

Try a different charger.

If all those check out, it is the phone. In my experience of 30 odd years of mobile phones, it is the lead!

You have to first know what type of rechargeable battery you have. lead-acid, lithium-ion, ni-cad? NEVER use an unmatched charger for a different type of battery, they can EXPLODE in your face. Your current battery may have a memory from incorrect charging procedures, your charger could be bad. You don't know enough to handle the problem yourself, take it somewhere, a car repair, or even a TV shop.

Where and how do I change the battery???

I can't find any reference to a Homelite model 720 generator but most battery charging systems do not supply enough amps to run a car starter. Battery chargers usually work in the two (trickle) to ten amp range. Car starters need way more amps to have enough power to turn an engine over, depending on the size and number of cylinders in the motor. Some chargers have a switch with a 60 amp 'start' position to help the battery turn the motor over, but without that there is little chance the charger side of your generator will supply enough amps to help your battery.

try taking the battery unit out,the battery should have a plug that fits to the quad disconnect the battery from the quad. the square end of the battery lead should fit in the end of the charger.its not the quad you need to charge its the battery you need to charge,hope that helps

ismail the charger you bought should do the job. By stop charging do you mean the light on the charger turns from yellow to green? Your scooter has small batteries 12/12 and don't require along period of charging. Now the scooter has a heat sensor for the batteries and will cut off charging when temp of the batteries gets too high. The older charger could have overcharged your batteries and made them weaker instead of stronger. I would suggest you replace the batteries (2 12/12AH) and charge them with the new charger. Remember to reinstall the heat sensors on each battery when replacing. If you have a digital voltmeter set it to 200 v dc and put the leads into the 2 outer plugs in the charger port on the battery pack. You should read 24-26 volts dc when the batteries are fully charged anything less would mean weak batteries. Hope this helps you

dont take a full from the charger as gospel it can still be tell you fibs,,, check the battery leads they need to be clean, and then try with a meeter to check the battery is good it may have gone dead flat and if this is so it may never recover to take a charge,,, however the charger will say its a full battery as it cant charge it any more,,,if you have a set of jump leads and a good car battery hook that up to the bike,, it should go then, and if it do,,, get new batterys fitted,,,,
il give you a tip here,,,,get a solar battery charger there not to pricy and if you hook it up to the bike battery when your going to leave it standing around for more than a week or so it will keep the battery fully charged or you,,, it only needs day light to work but in sun light it works much better, so if the bike is locked away in a shed put the charger out side in sun light,,,it cant over charge the battery on the bike,, i have them on my bikes all year round and the battery life is doubled so there a realy good tool to have they work on cars too? free power,,,good A!

Your SLA (Seal Lead Acid) battery is must likely past its useful life due to Sulfation and internal mechanical damage (corroded plates): your charger, like for most car lead acid battery charger is indicating that only a very small charging current is flowing just like when a battery if fully charged ... or the terminals are not connected (no current)! You can check if the charger is working by preferrably using a multimeter or connecting a know good battery unit to the charger.

All lead-acid batteries contain highly corrosive sulfuric acid, generate explosive gases and have warning labels which should be observed closely. For best results, charge the battery as soon as you know it is discharged. To charge your battery, follow these steps and important safety tips: Before Charging: 1) Read the charger manufacturer's instructions. 2) Put on protective eyewear, rubber gloves, work clothes and remove all jewelry. 3) Place the battery in a well ventilated area. 4) Don't charge a frozen battery. Allow the battery to warm to about 60?F before charging. 5) If applicable, remove the vent caps and check the battery's water level and, if low, add distilled water to cover the tops of the plates. Do not overfill. 6) To determine if the battery needs to be charged, test it with a hydrometer to determine its specific gravity and/or with a voltmeter to determine its state of charge. 7) If applicable, reinstall vent caps before charging. 8) While the charger is unplugged, connect the leads to the proper battery terminals. Note: For side-post and studded batteries, we recommend that you use adapters to insure adequate contact. For additional information regarding adapters, contact Interstate Batteries. 9) Set the charger to the proper settings for your battery, e.g. 6 volts vs. 12 volts, low-maintenance vs. sealed, standard automotive vs. deep cycle. 10) Plug in and turn on the charger. 11) Don't wiggle the connections to check contact while the charger is turned on or plugged in. 12) Choose the lowest amperage setting initially. Once the charger is on and the battery is charging, you may want to choose a higher amp setting to reduce charge time. During Charging: 1) Keep the vent caps on. 2) Don't allow smoking, open flames or sparks near the battery. 3) Don't allow the battery to become hot to the touch. After Charging: 1) Immediately after the battery is fully charged, turn off and unplug the charger. Continuing to charge a fully charged battery will severely damage the internal plates and shorten battery life. 2) Disconnect the leads from the battery.

Not the charger. It is either the battery or the charge circuit in the laptop. Most are on the mother boards but some have a changable dc to dc inverter board
