Does this charger truly go into "maintain " mode when battery is fully charged? One reviewer said it must be unplugged when fully charged.

when fully charged the green light comes on and the amperage drops to zero. I leave it plugged in and in this state until ready to use.

Ours is plugged in all the timeBatteries have been fully charged since and definitely goes into maintain mode when batteries are fully charged.I'm impressed with the charger so far

Mine seams to go into maintain mode. I have only had it for 1 month, will see what it does over the winter. I am using it on a electric tractor that is run about 4 to 5 hours a week to cut grass, it keeps it charged good and it is always plugged in.

This charger has thermal runaway protection which means it will stop charging when fully charged or if it detects a problem with the battery. No need to unplug, it uses very little power in maintain mode.

acording to the instructions, it goes into a "maintenance" mode after the battery is fully charged, which can be left connected indefinately. I have not personally tested that feature. I have not been able to bring back a "failed" battery with this charger or it's close competitor, as tested on several batteries. It does seem to extend the life of a near failure battery, but only experienced on one so far.

Basically an old wive's tale at this point. Modern chargers mostly detect when a battery is full and stop charging (or drop back to just trickle charging). I wouldn't worry about it unless a manual for a device specifically says to disconnect the charger after a full charge. There's so much mythology and repeated nonsense out there about batteries, chargers, and how they work!

I keep it charging regularly, but I myself have yet to drain the battery completely

NO! That is my problem with this. When the power goes off and then comes back on again the charger goes into a standby mode and will not charge. We leave home for several weeks at a time. If there should be a power interruption the charger will not keep the batteries in our cars charged which defeats the purpose of the charger. There are other chargers on the market that if the power goes off and back on again they will write resume with the charge code so you're protected. Battery Tender Plus returns to charge mode after power interruption. Hope this helps.

It does not need to be unplugged to play and can be used while charging but as in all rechargeable battery devices if you never use the batteries, keeping the unit charging all the time, you will ruin the the batteries in time and they won't hold a charge.

I leave my battery on the charger until I get ready to use it and the battery is always fresh, the charger cuts off when the battery is charged to the best of my knowledge.......

Yes, it'll go into standby once the charge is complete in order to not overcharge the battery.

The manufacturer suggest keeping the unit plugged in since it has an automatic charger that keeps the unit charged without overcharging. The other models they recommend charging immediately after use but do not provide a shelf life for the charge.

i believe the charger turns off automaticly after the battery is charged at least some do tho some chargers tell you that you are useing unnecesary electricity by leaving it on but i would suggest removeing the battery once it is charged.

This charger does have an auto shut off feature that's suppose to shut off the charger to prevent overcharging. I haven't needed that feature, so I can't tell you how well it works, only that's it's available.

It will keep charging your phone until you unplug it. I had my backup completely charged the other night, I left my phone pluged into it and by the morning the backup was drained because it never shut off. Even after my phone was 100% charged.

I have read reviews where it says that it has drained the battery. The instructions that come with the item also references unplugging the unit when not in use.

"Maintenance Mode/Float Mode charging" --- from the product description, so yes, the docked device is kept fully charged. The device itself is used as a jump starter.

I leave on charging station all the time since it shuts itself down when fully charged. Does not affect the battery if I remember correctly.

Yes, I keep mine plugged in so it never needs recharging...doesn't make a difference.

No, charging light stays on all the time. I leave it plugged in all the time and have used it till it is completely dead. It doesn't seem to have lost any time per charge yet. So far the only draw back I have with it is that there is no wall mount for it.
