Can this be used to bring back a dead lipo?

No, if you over discharged the Lipo the charger will not charge if the voltage is too low.

I have heard of people doing it with any charger, but it is dangerous and can easily cause a fire!! If you want to do it, do it outside in a safe place. You have to jolt it back to life with the NiMh or NiCd charge first, you have to get it above the dreaded 3amps. I have never done it but have friends who have, and yes they have burst one or two into flames!! I have also heard of them changing polarity, but have never seen that happen. I would highly recommend getting a laser temp gun to monitor the battery wile trying to get it back to 3amps. But like I said, THIS IS DANGEROUS AND IT IS BEST NOT TO TRY IT!!

Recharging a lipo that has been puffed, or has less than 1v per cell is DANGEROUS! Once a lipo has reached this point, continued use may result in fire, explosions, serious injury or death.

Unfortunately NO. When the manufacturer quit making the units, replacement parts also disappeared. Your charger may still be good, unless it has been damaged, and the battery could now be too weak to recharge. You are not alone in your disappointment. Too bad another manufacturer has not decided to make these handy, useful tools whose parts match all those Total Trimmer users.

depends on the condition of the battery. if it has 2 or less volts it will take along time to recover it.

It's a very small draw but anything left on your lipo too long will kill it. If used while in use yo monitor low cell voltages it's fine and doesn't affect much at all.

I used it to recharge a nearly depleted battery for my Suzuki SV650 motorcycle and the battery was only one year old. I just forgot to take it out of my motorcycle at the end of the season and drip charge it through the winter. It gave it enough juice to get my bike started so I could start the riding season again.

Ys, fits perfect but you cant use the old charger to recharge it, that battery does not have the balancer wire to charge but you can use a simple LiPo charger using a normal wire but your batterys life is can be short!!!

If you're trying to revive a dead battery, you want the NOCO Genius G3500. It has a repair function that is amazing. May take a couple days on a car battery but well worth the money. Yes, this is a very smart charger you can and should leave it connected to batteries that sit.

You should. I used it also to replace a weaker 4 amp hour draw battery. It's been working great for five months.

Yes you can. But you should read up on the different ways. Lipo's are dangerous, can cause a fire, and if you do not charge them correctly their life will be short. You can find all the information on charging Lipo batteries here on the internet.

Yes...only if it is not completely dead. What I mean, is that batteries don't last for ever, so if your battery is on its last leg, you won't be able to make it like new again. If, however, you accidentally leave the lights on or something with a newer battery, this will charge it back up. I hope that makes sense.

Plug it into the balance connector on your Lipo battery.Leave it attached to the battery.

What is helpful is to allow battery to go completely dead then recharge from scratch.

In theory that would work, but if the battery is discharged it will probably burn the module up trying to maintain the current

I myself haven't tried it on a dead optima yet, but I have had great success recovering traditional lead acid batteries around my shop. The oldest one was about seven years old. I (just my opinion) think it would.

You could do that, sure, but the idea of the charger is to maintain, not recharge. They should call it a maintainer instead! It won't charge a dead battery; rather, it'll keep a live battery from going dead. So--if you know the battery is live, you might do as you've said, but if your trailer was mine, I'd keep the battery attached to the charger full time. That's what I do, and it works. Eric

No sir, they don't have a balance charge lead like a LiPo does, you can't connect this to the main leads.

In my opinion, this tester is suitable for detecting good from dead batteries, and that's how I use it. For anything that is not full but has some life left in it, I would treat it as dead and in need of charge.
