The backup battery will drain in about 2 hours. Even after replacing with new battery, results are the same. Why is it draining before the main battery? The only way I can use this unit is to leave it hooked up to the charger at all times which does not make it mobile. The backup battery should last a long time.

I am listing this tip for the Nikon Coolpix 995, but the tip is valid for all Nikon Coolpix models.
The Nikon cool pix settings are saved into an internal memory.
The internal memory is maintained by an internal rechargeable battery, that is recharged from the main Li-Ion battery. If you leave your Nikon overnight with no main battery, or if the Li-Ion batteries have drained, then the internal battery will also drain , resetting the clock and other settings, saved on the internal memory. The camera may even drain in about 6 hours depending on the camera, normally it takes at least 12 hrs to drain the clock battery. If the internal battery is resetting immediately, after you set the clock, or just after few minutes, then the clock battery must be replaced. The camera must be disassembled completely to replace the battery located on one of the two main internal boards.
Nikon says that the clock battery loosing charge is normal. I quote what they say on the publication titled " The Nikon Guide to digital photography with Coolpix" "…Backup battery of the clock The clock-calendar is powered by a separate rechargeable battery, which is charged as necessary when the main battery is installed. If the camera has been stored with the main battery removed for a long period of time, the clock may need to be reset. Once the main battery has been reinserted, the clock battery will recharge in several hours, during which time the main battery should be left in the camera."Original file: Download here If the clock does not work at all, and is resetting immediately, even though the Li-Ion batteries are fully charged, then the best thing to do is calling Nikon, at the number listed on the owners manual, telling them that you did not do any improper use of the camera, and trying to get the fault repaired as factory defect. That is not always possible, and the decision depends on Nikon customer service. See also: Nikon | Contacts Ginko.
HI FRIEND A BATTERY WORKS ABOUT 1HOUR AND 30 MINUTES TO 2 HOURS MAXIMUM WHEN IS FULLY CHARGED. SO I SUPPOSE YOUR MIGHT NEED REPLACEMENT BECAUSE IT IS POSSIBLE TO START HAVING WORKING PROBLEM.SO I SUGGEST TO REPLACE IT WITH A NEW ONE AND IT WILL WORK PERFECT
Battery manufacturing can vary, along with review circumstances. Your battery may need to be reconditioned (Drained the battery to empty, charge to full, drain to empty, repeat) so that it can use it's full potential. There is also the chance though, that your battery is just in poor health due to overuse or manufacturing defect. If reconditioning is no help, then call Samsung and complain that your battery isn't lasting as long as it should be, and they may send you a new battery.
You can't run the calculator on the backup battery, nor do much else with it. The backup battery is there only to maintain the calculator's memory while you replace the main batteries. If you leave the main batteries out, the calculator will soon drain the backup battery.
Does the battery charge even after it drains. Even though it's a new alternator, it could still be bad. The battery could even have a dead cell because it's draining while you're driving. Sounds mainly like the alternator output isn't enough. Internal voltage regulator inside the alternator is usually a big problem, it can't be replaced, except by a new alternator or have yous rebuilt.
bateries have their own specifications.You can read it on the label.But,most of all it must be charge from 12-15 hrs. on its very first charging ( for a new battery) and later on or for the second time and so on, you may charge it 2 to 4 hrs.,sometimes 8 hrs..Leting you know,a battery can be charge even a short span of time,for example is 30 minutes only.In that 30 minutes try to measure its stored volt using a volt meter or a multi-tester,and the result is laready 12 volts (if your batery is 12 volts.)do you believe that? YES.! because a battery is so easy to store power.But,the problem is that its so easy to drain its stored power.You know why?because the current or amper of the baterry is still weak that the given specification.,.So,for short explanation,the longer time you charge your batery equals the longer time to drain the power.For example: when you charge the batery within 4 hours,thus the batery will be drained after 4 hours.
1. Maybe there's a virus.
2. Often restart can drain the battery.
Format it by pressing the green key or call key + no. 3 + asterisk(*) at the same time. But 1stly, turn off ur fone, then b4 the NOKIA logo appears, hold these following keys altogether. You will see the "Formatting" word afterwards..
Format it by typing *#7370.
