Why is my new battery losing charge?
A defective alternator can kill a battery if bad diodes or an internal voltage regulator prevents it from charging the battery. Or a diode can leak, allowing current to flow after the vehicle engine is shut off. A worn or loose drive belt, or a weak belt tensioner, will also interfere with charging.
Why is my battery suddenly draining?
A rouge app is a common cause for sudden and unexpected battery drain. Head over to the Google Play Store, update any apps that need updating (updates come around fast), and see if that helps.
How can you tell if its the battery or alternator?
If your engine won’t turn over or takes far longer than usual, it’s time to grab the jumper cables and attempt a jump-start. If your engine starts and stays running but won’t start again later, it’s likely a battery problem. If your vehicle immediately stalls, it’s probably a bad alternator.

Why does my battery keep losing its charge?
If you do not have a sealed battery, remove the battery caps and top off the battery “cells” (about 1/2- to one-inch from the top of the battery) with distilled water. A dirty battery top can “leak voltage” between the terminals draining the battery when not in use.
How long does battery last after full charge?
Normally, my battery lasts at least 4 hours after a full charge. But now all of a sudden, it has started draining in minutes. Battery seems to be charging normally.

Why does my Dell laptop battery drain after 50%?
It always had a problem which Dell couldn’t fix where while on AC Power it would start to discharge and not stay in charge mode. The “fix” for that was simply pull the power out and reinserts and it began to charge to 100%. So, maybe that also caused the old battery problem.
Is there such thing as overcharging a battery?
There is no such thing as overcharging a battery nowadays. Batteries now have safeguards. You should not drain the battery completely either. That was for old style batteries from years ago. Check the Battery Status to see if the battery has reached end of life.
