--"Protects battery from overcharge and discharge"--How does this protect battery from over-discharge? // (no connection to power used)

With no load connect, it doesn't prevent the battery from over-discharge from a load. The solar panel can leach power back from the battery during the night though, and that is the discharge referred to that the controller prevents.

When the battery is charging the internal voltage increases. When that voltage reaches a certain preset point, the controller is supposed to shut off charging current. It seems to work that way to prevent overcharging. As far as discharge, there is supposed to be a diode in the circuit that prevents current from leaving the battery but allows current to enter the battery for charging.

This is a battery maintainer, your batt. should be charged before you use this.

You should have at least a basic charge controller to avoid over-charging your battery and possibly damaging it. The panel has built-in diodes to prevent discharging your battery when there's no light on the panel.

I purchased as a gift for my son at Christmas, he's had zero issues. Once the battery is fully charged, disconnect. Removing the connection from the laptop when finished using would prove ideal. Keeping it connected kills the battery much more quickly. Contact Philips or Batteries Plus is a great place to look. Hope this helps and good luck.

Hi; Don , Your battery tender will start the charge step 1. Then step 2 it will go into a maintain mode where it keeps the battery up to full charge. Then step 3 it will float charge the battery, in other words it will cycle off and on as needed to keep your battery fully charged. It will not over charge your battery it will keep it fully charged. Hope this helps... Mike

You cannot overcharge the battery so don't worry about it. Also no harm done if you undercharge. I have had mine for years, and to be honest do not charge it regularly, and have not had any problems. These are really just guidelines.

For all intents and purposes, this device mimics the USB port you would find in any computer. The only difference is that some ports have had their data pins fixed in a particular configuration that signals to the phone that it may attempt to draw more current than the standard USB protocol would normally allow. It's important to point out that current is regulated by the *device being charged* and not the USB source itself. It is not clear what you mean by "overcharging," but every possible definition I can invent for that term would be under the control of the device being charged and not this device. In other words, this device does not receive any feedback about the status of the battery being charged, and so it provides as much current as is being requested by the electronics connected to the battery being charged. It is the responsibility of the battery-charging electronics to maintain the health of the battery. This device is rated to provide up to 25W of power across all five USB ports. That means that a port could conceivably provide up to 5A of current. However, this 5A specification is simply an upper *limit.* The actual current provided is controlled by the device being charged. All that this device is responsible for is providing relatively clean DC power to each of the 5 USB ports. As far as I can tell, it does that very well.

It will not damage your battery if battery keep in the slot as it has power protection circuit. Smays Smays

I'd look in the manual for something saying "It will not overcharge if left plugged in". If you can't find such, then I'd plug it in and check the voltage on the battery every hour for 4-6 hours. If the voltage never goes above ~14.5V everything's fine, but if you see 15V or higher then you're "overcharging" and want to pull the plug.Another option to consider if you like the idea of keeping it "freshly charged" would be to put it on a timer that comes on for 15-30 minutes each day, but isn't on 24/7.

This is a question to ask of the manufacturer. I would think their is protection in the charge controller to prevent any damage, but I have no knowledge of that.

DO NOT use the side port for charging. It bypasses the electronic charge protection built into the battery and will destroy it..... I really don't even know why it is there, other than to maybe draw current off of it when it is disconnected from the radio. IT IS NOT A CHARGE PORT!..........

No, you should remove batteries when they are fully charged. The unit has built-in protection to prevent overcharging but why put it to the test continually? The risk of fire far exceeds the benefit of having a fully charged battery.

Usually, over 80%， device has overcharge protection to protect battery. The overcharge protection is coming with device not charger I think. Hope this helps

Dear ANDRE, I am not sure what you mean. When the battery bank is fully charged,The controller will automatically close charging circuit. At the same time, In order to protect wind turbines. The controller will emergency stop wind turbines, Like brake.If you still have any question, Please contact me when you free.Thank you for your inquiry.Your sincerelyKate

We do it all the time. Charging over night. Doesn't seem to harm the battery. we are very satisfied with our unit. Hope this helps. If you are concerned, perhaps you should contact Inogen.

Personally I think it preserves the battery if you store it emptied. If you were to store it full, the battery would eventually drain anyways.

Most vehicles use a negative ground. In general, when servicing a battery, you should always disconnect the ground side first. That way, if your wrench slips and you hit part of the vehicle, you'll just be connecting the ground side of the battery to the ground of the vehicle, which causes no harm. If you slipped when loosening the positive post, and the ground was still connected, you could connect the positive terminal of the battery to the ground, which would cause arcing, or worse. So, because of that safety issue, people always disconnect the ground side first, and switches like this are usually placed on the ground side. Disconnecting either battery terminal will stop the battery from charging, since you no longer have a complete circuit through the battery. If you leave your RV plugged in constantly, and leave the battery connected continuously, be sure that your RV's battery charger is well regulated. (Although, perhaps that's why you wanted this switch in the first place-to prevent your charger from overcharging the RV battery.) Handy Bob's Blog, HandyBobSolar, has a big page of good information about RV battery charging. It's the page entitled "The RV Battery Charging Puzzle". I think I'm not allowed to insert links here, so you'll need to Google for it. Handy Bob says the biggest problem with typical RV converters is that some of them never get the batteries fully charged, even if left plugged in 24 hrs/day. Handy Bob goes on to suggest buying a large automotive battery charger, one that puts out 25 amps, and use that a few hours each day. That sounds like overcharging to me, but he's the authority here. Personally, I use a smart charger to top off my batteries, and I generally disconnect them from the vehicle before charging, and it's a low-amperage charger, as well. Mine's the 7 Amp NOCO Genius charger, and I think it's sufficient, but I'm only charging medium-sized batteries one at a time.
