when the red light on steadily on -indicates the charger is hooked up correctly and is chargingwhen the green light is flashing it means the battery is charged to 80% or greaterwhen the green light is a solid green (no flashing) the battery is fully charged and the microprocessor is monitoring the battery and will keep it fully chargedall this information is on page 7 of the instructions provided with the unit

The battery will not take a charge.Hook it up to a battery you know to be good.You should get a blinking green then a change to solid green.If the tender does the same red to green then the tender is probably faulty.

My tender flashed red and green. I was told that means the battery is bad. But, since I have two battery tenders, I tried the second one and it worked fine. The first battery tender was bad. I have to say I've kept that hooked up outside inside a Tupperware type plastic box to protect it for several years in snow, rain and 0 to 100 degree temps. Maybe the weather finally got to it.

When mine flashed red and green that meant the battery was bad. I changed the battery and it works great now. If your battery was run down several time then it could have damaged the battery. You'll have to get a new battery.

There is a light on the plug thats flashes red when charging and I believe turns green when done.

Flashing red light means it's functioning properly or that it has a working battery

That indicates that it's charging. It will blink faster as it gets closer to fully charged. It will stay solid green once it reaches about 4.2 volts.

The red light means it is charging. It changes to blue (I think, or green) when it's fully charged.

Mine does go from red to green but it takes a long while to do so. Batteries charge rapidly and then each addition step takes longer so sometimes it takes really long for the cut-off to "trip". Here is a suggested test: charge the battery overnight then unplug it but do not use it and let it cool down. Now plug it in again and after about 30 minutes, see if the battery is hot. If that is the case, you have a defective charger and should consider returning.

When you turn it on it will flash a light twice indicating the battery level. Just look to make sure the light is green. It will change to yellow or red (I can't remember which) when the battery runs low. My battery lasted a very long time, 17 months before I had to change it.

It means that the battery is in soft start charging. If willeventuallh go to full red a d then green when it is fully charged. It shouldn't take that long being that the charger is a one hour charger.

You are correct, when plugged in and the batteries are installed the light will turn red when it is charging. Once it is finished it will turn green.

When you plug it in with a dead battery, the light should be red., When it is done charging, the light will be green. If your charger does not do this, you have a bad charger. I had bought a lower priced model, and it did not work. So be sure to get a quality charger.

The controller has LED indicators. When the battery is full, the battery LED indicator will flash green.

I think it means something is wrong. the red light should flash continually then the green light will come on occasionallyand be a solid light. -

mine turns red immediately and then b ack to green when it is charged. I would get in touch MSA 30X, you may have a faulty charger

The light on top was alternating red/green. I thought it might mean the batteries, but I checked & they are fully charged.Now, I can't get it to work at all, no lights, no pump, nothing...yes, the batteries are installed correctly. Any ideas?

The charger will flash red when the battery is mostly dead. As it's almost full it will flash green, however when the battery is fully charged the light will stay a solid green. Hope this helps.

It blinks red, yellow or green depending on the state of charge (voltage I assUme) of the battery.

When the battery is less than 75% charged, the large LED pulses red as it is charging. Above 75%, the LED turns green and continues to pulse. When within 95% of full charge (I think that's the amount), the LED is solid green. This battery tender will alternately slowly discharge the battery a small amount and then charge it again. It is very gentle on the battery while cycling the charge at a low amperage, which keeps the battery's chemistry at an optimal condition for long life.
