if i connect this to my van battery will it over charge or does it have a diode built in to protect the battery from being overcharged thanks

This device does not have a mechanism built in to protect the battery from being overcharged; you need to buy an extra Charge Controller.

It may overcharge your battery though not likely.It does have a bypass diode which is only useful when connecting multiple panel in series. The diode has nothing to do with overcharge protection.You should consider adding a diode in series with the + lead to prevent leakage at night. Again this will have no effect on overcharge.It may be easier to add a charge controller.

You have to be careful not to have over charged the battery. If you did overcharged the battery by 30+ minutes the battery becomes useless or you'll notice a diffrence in power. If you know forsure that its not the battery then get yourself a circuit tester and start following your battery circuit flow, you may be able to narrow it down and hopefully find a quick fix.

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.

According to the information I read the built in charger is a float charger meaning it will not overcharge if left plugged in. There is something else offered if you keep it in your vehicle, they will send you mail when it will need a recharge based on when it was last charged. I might add I am very pleased with the performance of this unit.

You usually have to have some type of controller to prevent battery overcharging. I hooked my solar charger to a gate opener that has a built in controller for the battery.

Yes, Internal over-charge and over-discharge protection to prevent battery over use.

A charge controller protects the batteries from over charge.The % charged is probably only a meter.Also, a controller should convert PVC voltage to match voltage rating of batteries (16-19v to 12v)

Yes it is. It will send a charging current to your battery in three stages. As the battery starts to approach full charge it will cut back the charging current to keep from over charging the battery. When the battery reaches full charge it will go into a maintain stage which will keep the battery charged.

It does have an overcharge safety, but I'd never advise leaving these types of batteries in any charger for more time that it takes to charge them, let alone days or weeks. You're just asking for trouble in that scenario.

Yes, it does prevent over-charging. This is accomplished by the charger switching to a type of stand-by mode when the battery is fully charged. Its LED display shows the specific cycle in which the charger is operating. If the battery power drops to a level below full charge, the charger switches to charging mode to top-off the battery again. I am completely sold on this CTEK Charger! Also, it CAN re-charge a supposedly "Dead" battery, if the battery is still capable of accepting a charge. This is achieved through its "de-sulfation" (altho this is not the correct term) process.

I charge 2 6v lead-acid batteries (in series) with it for RV - have had no trouble. This link gives the various charge rates and protections. Not sure how the controller would handle 1 bad battery of 3 wired parallel. http://www.directdepot.net/manuals/Go_Power_MAN_GP-PSK_80.pdf

I don't know what you mean by "over charge" but this thing is just an inverter with a variable regulator. If you give it too much input voltage, it probably fries...so put a Zener diode in front of it or have an actual regulator on the input side. On the output side, the caps are its maximum output voltage. You might want them to be higher, but the inverter won't let you...

No. I tried the same thing. But there is circuitry to prevent overcharging which would damage your batteries that is missing in the circuit.

According to the instructions included with the unit, a charge controller is not necessary. "The factory installed diode placed in line with the positive output from the solar panel will prevent reverse current back feeding from battery through the solar panel at night. The use of a blocking diode is typically done when a smaller sized panel is designed for maintaining a float charge to a battery, and a voltage regulator is not used."

I cannot answer that question. I think from all I have read about this charger it cannot overcharge or undercharge its built into the charger. I use mine to charge my boat trolling motor and when the green light comes on I always disconnect it. I have never left mine on to continually charge. Some battery chargers will damage the battery if they don't switch to the maintenance cycle. But once again I think this battery charger it's all built in to not overcharge. That's why I bought it. Hope this helps some. I am just telling you how I use mine and I have never left mine hooked up past the full charge. Sorry. I cannot answer that question.

No you will need a charge controller such as this one Docooler Solar Charge Controller Solar Panel Battery Regulator Safe Protection (10A) There is a overcharge protection circuit within the charge controller. How long it will take depends on how low it is and how much sun is available.

Yes....be sure and use isolation diode between battery and charging system as not to run down vehicle start battery
