I have a dash-cam on my Motorcycle that I discovered places a very small drain on the battery even when turned off and I haven't used the motorcycle for a long time. Perhaps this drain is required to keep the CMOS battery from dying Last year I was away for 3 months... the trickle charger remained on, but the 1.5 year old battery died, I replaced it with a new one. This year, I've been away and then injured so didn't use the motorcycle... the trickle charger remained on, the 1 year old battery died. On both occasions I should have just disconnected the battery... I'll do that in future, but I thought the trickle charger was supposed to take care of this stuff. Mrs.T near new Yamahs Grand Filano Hybrid battery died, she did not make sure the thing was turned off, it doesn't use a key. Took the battery back to dealer, they said it was finished. Loooong story short, took the car and bike battery out connected them together for an hour, the bike battery now thinks it is part of the car battery. Tested the bike battery, 9 volts, connected the smart charger, took about an hour, fully charged, still on the bike now, 2+ years......🤗 Link to comment Share on other sites More sharing options...

Or if your wife left the lights on all night ? Do you have an older trickle charger for those times ? Most people just jump start. Then they might get enough power to get their "smart" charger to work. I have seen people fry computers jump starting. I was always told growing up to just throw a drained battery on the trickle charger overnight. And avoid jump starting and bull<deleted> if possible. But with this new garbage, you just cant. Unless you trick them with a 9 volt battery or another car. I don't think you know what you are talking about.

Perhaps this drain is required to keep the CMOS battery from dying. Last year I was away for 3 months... the trickle charger remained on, but the 1.5 year old battery died, I replaced it with a new one. This year, I've been away and then injured so didn't use the motorcycle for 3 months... the trickle charger remained on, I went to use the motorccycle last week, it powered up but it seems there was not sufficient charge in the battery to for the starter motor to engage and start the bike. On both occasions I should have just disconnected the battery... I'll do that in future, but I thought the trickle charger was supposed to take care of this stuff. The "smart" charger probably found a reason to deny you a charge. Probably because it was hooked up. Completely unhook it and try again. This is an appropriate application for a "smart" charger but you never know what that thing is going to do. You could just get a dumb charger and put it on overnight every once and awhile. 3 1 Link to comment Share on other sites More sharing options...

You could just get a dumb charger and put it on overnight every once and awhile. Not really ideal when away for 3 months... It is also my understanding that once a battery is fully drained and has been for a while, it will not charge properly again. The convenience of a battery tender is 'the plug and play' function, rather than having to go through the hassle of disconnecting a battery every time I go away... The tender does the job for a month to six weeks, any longer than that and the battery is allowed to drain. I suspect something could be up with the tender itself (it about 7 or 8 years old).

jvs Posted April 20 Share Posted April 20 6 hours ago, Harsh Jones said: Long story short, these pieces of scrap will not recognize therefore not even attempt to charge your battery if was fully drained. So if something was slowly drawing power from your battery as your vehicle was parked for a week+, and the battery is dead, hooking up one of these pieces of useless garbage will do nothing. With the old normal trickle chargers, if you drain your battery, you throw the trickle on for 24 hours or so, and your battery will come back to life. You plugged them in, struck the leads to each other to make sure there was power, and clipped them on. But but... you can trick your "smart" charger into doing what a charger is supposed to do a couple different ways, with a small 9 volt battery or with another car battery. Anyway I already threw my "smart" charger in the garbage (after smashing it to pieces on the concrete, very satisfying) and got a real charger. That's a little harsh my friend. 2 Link to comment Share on other sites More sharing options...

transam Posted April 20 Share Posted April 20 1 hour ago, brianthainess said: First you should have disconnected the battery before charging. I got one of these 'Smart chargers' for about 250b from Lazada, it automatically goes into 'repair mode' a completely flat battery was charged enough in 3 hrs. to start the car. Edit; it also has an internal fan that starts when it gets hot. I have one of those, if anyone buys one be sure to buy the 7 amp one. They only work on a battery that has at least 7 volts, but that can be got over by my previous post info... 1 Link to comment Share on other sites More sharing options...
Negita43 Posted April 20 Share Posted April 20 I have two - they work fine BUT always if I am going away for a longish period I disconnect the battery - also you can buy a solar based trickle charger that will keep the battery topped up used to have one in my camper van. 1 Link to comment Share on other sites More sharing options...

All of the dumb trickle chargers will do this. Are you seriously saying you would throw out a car battery because someone left the lights on all night ? Not sure where you got that i said i would throw out a car battery? I just explained that you were blaming a trickle charger when it didn't do what you thought it would do. If you have a dead car battery have it tested and you'll know if it can be recharged or not but a trickle charger probably isn't gonna do it in any short amount if time as they aren't designed for that Link to comment Share on other sites More sharing options...

So you are saying by default that you would throw away a good battery that just needs a charge. I have charged drain batteries a million times with old style constant voltage trickle chargers. And nobody said anything about a short amount of time. It takes at minimum a full night or all day. Link to comment Share on other sites More sharing options...

Harsh Jones Posted April 20 Author Share Posted April 20 (edited) For those who don't know , "repair mode" on a "smart charger" is not some high tech thing. It is just like having a dumb charger hooked on in the first place. From Hagarty https://www.hagerty.com/media/maintenance-and-tech/wrenchin-wednesday-outsmarting-the-smart-battery-charger/ While you’ll often find that the battery is as dead as Zed and will need to be replaced, there’s an off-chance that the sulfate layer on the battery’s lead plates can be removed with a long recharge. If your “smart” charger doesn’t already have a desulfate mode, which bypasses some of these safety measures and charges the battery in waves to attempt to break-off and dissolve the lead-sulfur crust that have built up on the battery’s plates, you can use a helper battery to trick the charger into activating and providing its full juice — which will hopefully start the desulfation process inside the battery. In other words, a dumb charger is doing the exact same thing that a "smart" charger does when it in "repair" or "desulfate" mode. And is why dumb chargers can revive dead batteries Edited April 20 by Harsh Jones Link to comment Share on other sites More sharing options...

I’m pretty sure they drive on the wrong side of the road. The problem with your "smart" charger is , if your battery is drained too much , it will refuse to charge it and mark it as defective. When there's nothing wrong with the battery at all. You will be throwing away a functioning battery. And the owners manual of your charger will instruct you to do this. But a "dumb" charger could just bring it back up to charge. But that's not a problem. You can trick your "smart" charger into being a dumb charger so that you can avoid throwing away your perfectly ok battery.

The thing you need to take the hammer to is not the trickle charger but your head. Im done with this discussion and with you. Have your mom charge your diaper and then better day.
