Seem to be working well but, turn the output charge off at 13.5 volts (Some what less than 14.4). How can this be adjusted to 15v?

While I could certainly be mistaken, as an Electrical Engineer, I am fairly certain that there is some kind of DC-DC converter inside that is built out of solid-state components, and is thus fairly permanent. Without completely gutting and redesigning part of it, I would say that it is what it is. However, depending on the application, voltage outputs can change. Charging a drained battery may occur at 13.5 V for example while topping off a full battery may be somewhat higher. Why is it that you need it to be higher?

i do not believe that this unit is adjustable that way. It works well to charge a 12 V battery (2.2 V/cell x 6 = 13.2 volts); and the "floating" maximum voltage is meant to mate well with this voltage. Current is what you need lots of, not volts. Connect a battery to it & it should read 13.2-13.4 on either battery or panel side if working properly

I recommend you stick with same output V as the original equipment. I don't know what you are powering up, but some circuit board items might not be able to handle the added volts.

I think 5V, 1A is low. The supplied adapter has 24 W and the output is 5V, 2A. Maybe the device will be recharged with 5V 1A, but much more slowly

My battery voltage is consistently about 13.75 volts. I retrofitted a desk lamp with one of these bulbs, it's on for at least six hours/day and i've had it for about two months. Maybe just be mindful of the "very hot" warning, and don't use it in a tightly enclosed fixture for an extended time.

Hello, if I understand you correctly, the output voltage is less than what is required? Maybe a defective battery.. Although, dual voltage rechargeable, 220\50htz, may be the problem. The same with 110/60htz as well. So, it could be the charger. I have had zero issues with mine. Check the component that your using them on too... Hope this helps.

These lamp substitutes are resistively ballasted and I would not expect them to survive at any DC voltage above 15V. If radio frequency interference is not important, there are better choices efficiency wise and light output versus charging/discharging. A discharging 12V "house" battery is at 13.4 volts or less, usually between 12.6V to 10.6V (lower cutoff). These, or similarly passively ballasted design, are a "must" if you want use a HF radio with the lights on. I haven't had any fail and they operate much cooler than the 1156's they replaced.

Mine read just at 12V when received so I didn't charge any more before installing in alarm system. It is working fine.

Looking at the charger now it's specs read output 5.7v. 800mA. And yes USA plug config.

I think that it's the output from the battery rather than the chemistry. I used li-MH rechargables, with an output right at 1.3v. You might be ok at 1.4, but you're right on the edge at that point. Also, pay attention to the color change rate. One of the RGB leds being offered is a nice slow rate, and the other FLASHES

This is not a good option, I'm sorry. I suggest looking for a 10watt 12v panel that discloses the actual specifications of the unit. The output voltage is undisclosed and I had very irregular performance.Hope this helps...good luck.

The model that I have is for 120 volt use only. I guess maybe use a converter or something. Hope this helps.... Pat.

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.

I used 5V with no problem. Couldn;t find the specification but everything above 2.5 i think is considered a high

Hi, deeply sorry for replying late. Mine came with a 5 Volt...1000mA (- o +)I don't understand why yours is missing the power adapter, but it shouldn't be expensive. You might find it in amazon or ebay for a cheap price.I hope you find the correct one, you don't want to burn your converter

The package says 1.2 volts, but mine are at 1.31 at a 90% charge. I just checked them with a digital multimeter.

There is a voltage issue, sadly. You need a step-down transformer, which is what I use.

None Note this is s bang bang controler that is not ultra efficient as a battery charge controler. On at 13 v off at 14 v.
