The setting box isn't working can i get a battery of charge it myself?

You have it set on automatic or manual .. If it is set for automatic the charger will cycle on and off so the battery does not charge too much. If it is manual when battery reaches charged voltage, it is time to disconnect.

try your regulator that does have a position in charge

If the security light is on then the car thinks someone is trying to steal it. If you can’t make the remote work then you might be able to clear it by disconnecting the Negative battery cable for about 10 minuets

You can try to try a different charger,if it doest charge the battery,try to use your charger to a compatible phone. If it charge the second phone,that means that your charger is fine,it might be a battery issue. For sure,either the battery or the charger needs replacing.

your charging system isn't working, if you replaced the battery and it worked for a few days, then its not being re charged after starting, I'm assuming you cleaned and tightened all the battery post connections when you installed the new battery , if not do so ,, charge the battery from an outside source, once you know its fully charged,, use a meter, and start the car ,, check the voltages at the battery posts,, you should be getting a reading of 13.5-14.5 volts, if not your alternator isn't charging the battery

Have the battery load tested to determine it's ability to take & hold a charge. It could have a bad cell that will drain the good cells. Your local auto parts will test the battery free of charge.
I hope this helps.

Return it as faulty goods to the retailer

Your battery MOST LIKELY has lost some of the battery cells, which will cause it to get a partial charge which will show it as a FULL charge when in fact it isn't getting a full charge. You should try taking it to get the battery tested and they can tell you if it needs to be replaced. I would guess they are going to replace it for you. A new battery should run around $90 for a motorcycle. Let me know if this helps you out. Jeff from fixya

if its a new battery it could be as simple as it wasn't charged when you purchased it, If it was charged and your mower isn't charging it, the power source to the battery from the mowers motor isn't working properly,, not knowing if its a 12 or 6 volt system you need to check the battery ,, see which one it is,, using a multimetter ( if its 12v ) check the battery after you charge it with an outside source ( battery charger) you would have a reading of 12-12.5 volts on a normal check,, then start the mower, and check the battery as its running,, you should get a reading of 13-13.5 volts minimum, if your not, the alternator or magneto isn't working properly, if you do show the increased voltage at the battery connections, then you need to clean the contacts since the charge isn't reaching the actual battery

Batters won't hold charge and work properly it sat up for that long. replace batterys
