It transfers power in the form of amps to a 12v battery while maintaining a safe level what are the highest paying jobs out of college charge. Upon connecting it, it will conduct a series of checks to ensure the battery is functioning normally and detect the current level of charge. If the battery is below a certain level of charge, it will activate bulk charge mode, delivering its full charge at a constant rate.

From minimal power usage comparable to the power consumption of a light bulbvisual charging indicators and a compact, lightweight construction, there are countless reasons why these are the ideal choice when it comes to charging. I have another Battery Tender connected to a car battery for years and the green light stays on steady but does not flash. I have three battery tenders. Is there a reason why they just quit charging?

Harness the power of the sun with this Battery Tender® Solar Panel with built-in smart charging controller. It's % portable and ideal for battery charging and maintenance, and for storage space without power access. Battery Tender® solar panels are available with a built-in charge controller to prevent overcharging. A completely dead battery should take at least hours or more with a Battery Tender Junior ( amps), and with a Battery Tender Plus ( amps). Unfortunately, these chargers cannot begin to charge a fully depleted battery. Product Review for Battery Tender Personal Watercraft Amp Charger. Designed to fully charge and maintain without damaging effects caused by trickle charging; Complete 4-step charging program (initialization, bulk charge, absorption mode, float mode).

Forgot your password? I've been hearing about these three for sometime now and, some use a battery tender, some use a battery maintainer and some use a battery charger.

I have a charger that does all this as needed. When it gets battery to where it should be it stops til battery needs to be brought back up to full charge. Also it will handle Glass Matt Batteries. For some reason you can ruin these with a regular charger. Tenders and maintainers are cheap and do not charge. Good smart chargers cost more and will do it all Jack is right. Also has desulfating cycle which breaks up the crud that starts to form in your battery and will kill it.

Also gives reading as to output of battery, has boost starting cycle, float cycle and a and 40 amp charging cycle. Chargers just ain't what they used to be. When plugged in, they monitor the output voltage of the battery and if it dips below a certain level they cycle on and bring the voltage up to the proper level then turn off.

I have a nice Sears charger that allows you to select the charge rate and type of battery and does shut off when it reaches a full charge, but I found out the hard way it is too over high tech for my Deka battery. If the Deka gets waaay too low, the charger eventually gives up and says the battery is no good when it is fine.

Put an old fashioned simple charger on it and it eventually charges it up I would stay away from "float" chargers. They do not have the intelligence to properly "maintain" a battery. I use the "tender" from batteryminder, it stops charging and waits until it needs to charge again based on the battery voltage as it drops over time. It also does desulphation, which will ruin a battery that has had too many charging cycles from almost drained condition to fully charged.

I only use the tender when the bike will sit for weeks or more. I have yet to have a battery go bad within years. I buy a new battery around that timeframe, needed or not. BAttery Tender is a name brand, and is a "smart" charger that will determine a batteries level and charge it to proper levels and then go into a float mode and if the battery falls below a certain level it will bring it back up again.

I have used them for decades and they are the original and I think still the best. These are NOT intended to bring a dead battery back from zero. They are not good for batteries that are on their last breath. I have a charger for heavy duty use, but for just keeping a good battery healthy and ready, the Battery Tender brand is good, and I just buy the "Jr. There are other good ones out there, but I just stick with the original.

There are also some junk units that may do more harm than good. A tender or maintainer provides automatic operation and less than a trickle charge. So it would take a very very long time to bring a very low battery back to full capacity.

It may not even be able to do it at all. It is designed to keep a good battery at it's peak. It uses very little current.

This is needed today because of parasitic drains such as keep alive circuits on modern vehicles. A battery charger is capable of higher current outputs. Some chargers may incorporate the features of a maintainer while others may not. Most chargers will have several selectable features which you have to decide if they meet your needs. This a little off topic but I think this was a better place to post rather than starting a new thread. The auto parts store manager pointed out something I was unaware of and wanted some more opinions on the subject.

He said the maintanece free batteries can fully discharge and then will take up to 48 hours or more of trickle charging to get them back up to full charge. He said the bikes alternator puts out so little current that it will not charge the battery after an hour or even much much longer. It was a cheap trickle charger from Harbor Frieght. I put it on a 2 amp charger with a shut off. We will see how it does. It is one of the 55 amp starter, 10 amp charger and 2 amp trickle charger.

He was right about it not charging while the bike was running. We jumped the bike then ran it for an hour and it had no more charge after riding than it did when we jumped it. We push started the bike and it ran ok on the way home. We had this problem before where once it is drained down, it wont take enough charge from the bike to fire it back up. I have never seen this before on a bike. Is it just the nature of the new maintance free batteries.

I think I have seen my venture with a low battery many many times and after running the bike for a while, the battery takes enough charge to start the bike. I have always had wet batteries in the venture. By the way, I suspect my cheap chargers from Harbor Frieght were the type discussed for just maintaning a fully charged battery. They will put a charge in but I do think it would take days. I had it on the charger for several days last week then put it in the bike. It started right up.

I checked the bike and it was putting out We rode for about 15 - 20 mins then parked the bike for a few days. When I tried to start it yesterday it did not have enough juice to turn over the motor. I guess this leads me to believe the cheap charger really never fully charged the battery and the bike is not charging it either.

I've never needed to use a Tender on it at all. AGM batteries are extremely slow to discharge. That said, I ride almost daily with a modified charging system that puts out no less than Now, playing with my Tender Jr. A Tender or HF will take a long time to bring a deeply discharged battery even close to topped off and more than likely it never will. It's not designed for that. But with standard charger the 2 amp setting should show the battery getting at least But if the bike is charging at If the AGM is dropping volts that fast there are two things to consider.

A massive drain on the system when shut off, or the battery is faulty. But from my experince with the AGMs, they are a huge improvement over wet cells.

More cranking amps, more reliable, and tough as nails, DEKA is one of the best on the market. If it has been that deeply discharged it will take a while to bring it back up, and that is a chance it may not come back to full power.

Your bike's charging system should keep your battery charged. If it isn't doing so something is wrong with it. Keep in mind however that a typical system doesn't provide juice below rpm usually.

It must be spinning enough to work. Below that point you are operating off the battery. I put the battery on the bigger amp charger and within a few hours it said fully charged. We put the battery in the bike and road for about 5 hours with stops at about every hour or so. It started every time as one would expect. Brought the bike home and put it on the battery tender that I just purchased and in about 3 hours it went from charging red to fully charged green.

I'm going to let or it will site for a couple of days while I'm out of town. I'll bring it in again and have it load tested and see what happens. When I told this to the shop owner where we were today, he smiled and said that bikes alternator has no where near the out put needed to run that jacket and the bike. I believe him. I have not checked the specs on this maurader but as dissapointing as it is, I do believe it. I swaped out a honda CBX alternator for a newer one off a zx10 or something and it is way better but I think it would be a different story on this bike.

Maybe not. I think we are headed for the new Suzukie with the batwing fairing and sound system. She can get her feet on the ground and I think she do just fine on it.

The shop owner said do I believe him? Funny thing about all this is that I'm still looking for that bike that meet or lives up to the 88 venture I been riding for the last 20 years. I had my girlfriend sit on it today just so I could fantisize about her being about to comfortably handle it. She would be so happy if only her legs were a few well maybe 6 inches longer.

Funny she says that about me too.
