How can you tell when the batteries are full?

There is a relief valve on the plug. When you get them full it will weep out of that hole. Time to quit pumping on the fill bulb. When you disconnect the fill bulb and tubing quite a bit of water remains in the tube. Pull tube out of water jug and drain both ends bag into jug. The whole system is slick for hard to reach batteries. Spendy, but the convenience is worth the price.

No more water can be pumped into the batteries once the full mark is reached. Love this product. Makes it very easy to maintain 2 12v rv batteries that aren't the easiest to access.

The bulb you squeeze gets hard. I love the system for my hard to reach motorhome batteries.

There is no visual method. I rely on the bulb pressure. When its not possible to draw water from the fill jug (and the bulb becomes hard) the batteries are full. I've confirmed this via test on 2 of my back batteries (removed and checked afterward). Hope that helps.

The valves in the battery close when the float rises and no more water flows thru the tubes. The squeeze pump gets hard and won't squeeze anymore. With this setup you can't see any pop up like the systems in the golf carts at our course, but this system costs about 1/3 of what one of those setups cost. For the money it is OK.

After the Qwik-Fill battery fillers are installed on the batteries you attach the pump which has a quick coupler with a check valve. The handpump has an integrated check valve which allows distilled water to be drawn from the source and then distributed to your batteries via the pump. During pumping two things will be noticed. 1. The pump will have low pumping pressure resistance as it is squeezed to fill the batteries. 2. As the pumping is taking place water flow is visible through the clear transfer tubing. Once the batteries are filled to capacity a distinct hard pressure will be felt in the hand pump. The Qwik-Fill battery inserts have a check valve which keeps the batteries from being over filled.

There are 4 bright blue LED's on the top of the device. When all of the LED's are ON the device is fully charged. As the device discharges the LED's go out. They will also be on as you are charging an external device to let you know how much battery is left. It's very easy to use and read.

I haven't had my battery die out yet, with that said it doesn't appear to have any manner to indicate a low battery. The instructions do no mention this either.

No visual indicator. Perhaps, you notice buildup :-) . I use rechargeable batteries, changing it when I notice little slowdown.

There is a little clip that you push the AAA batteries against when you put them in.Look closely and you will see them. Hope this helps

When the battery is almost exhausted the indicator turns red. As the battery charges, the light blinks green. When fully charged the light remains a steady green.

No, there is no indicator. At full power it lasts about 1 and a half hours, maybe a little less so best to charge it daily/every second day

There is a battery level indicator on the battery. You press a button and a series of green indicator lights show how much charge it has.

There is no "low battery" indicator. Since we use ours for the driveway, it works every time I leave or come home. When it stops working, I change the battery.

That indicates battery is fulley charged and desulfated. It may take A while to finish the desulfating cycle but it is well worth the waiting, it will give your battery much added life.

There is an indicator on the front that shows percentage charged and it stops charging when full automatically.

There is an LED light. It's green when they are ready to provide charging, orange (hard to see it different than red) when the batteries are low, and red when the batteries don't have enough charge to charge something. It stops charging the batteries when they are full. The light also says when the batteries are done charging. It blinks when they are charging. What the light says is printed in the bottom of the unit.

Let the battery charge for awhile then take out the battery. There should be a small dark button on the battery itself. When pressed a number of lights will come on on indicating how much charge it has. If this lights do not appear I would return the battery for a new one.

It doesn't give you any warning when the battery is getting low and the way to tell when the PowerBot is dead, is that there's a button for the flashlight, when the flashlight doesn't come on, then you know it's dead. That's how I know anyways!

On the display, the meter shows the battery, with the amount of charge left on it. But it does not give a precise number. You have to estimate it from the simple diagram.

You can check voltage , but u can't do a load test to confirm battery condition !

The manual says "When the batteries are nearly empty, the battery indicator blinks", it does not mention anywhere a sound.http://download.p4c.philips.com/files/d/dvt5500_00/dvt5500_00_dfu_aen.pdf
