duracell 4 amp battery charger and maintainer vs battery tender

It is one of the 55 amp starter, 10 amp charger and 2 amp trickle charger. I'll bring it in again and have it load tested and see what happens. I believe him. The voltage is then maintained at 14.3 while the battery absorbs charge at its own natural rate. Most motorists who purchase a battery charger do so for one main reason, to recharge a dead battery. about 60 bucks on sale but does it all. Automobiles are driven daily, so their batteries don’t get much chance to self-discharge. When viewing the current waveforms in this article, the reader will notice evenly spaced downward spikes. The difference between a battery maintainer and a charger is that a maintainer is designed to be on the battery for an extended amount of time and can detect when the battery is at its peak charge; and once its reached, stops charging the battery. For that last reason, we don’t consider the Yuasa 900 to be a true three-stage charger. This is after it had been on the cheap trickle charger all night and the Autozone manager told me it tested good but only 70% charged an hour earlier. I've been running the DEKA ETX18L for going on 5 years. If a thorough charge and long term float maintenance are of equal consideration, without the occasional need to manually “exercise” the battery, we’d substitute the Yuasa 900 into this group in place of the Schumacher. The Battery Tender Plus High Efficiency model was designed to replace the original Battery Tender Plus in the California market. Battery Tender Plus by Deltran The Battery Tender Plus, like the others in this comparison, is claimed to be a three–stage charger/maintainer. God I need more time off. The unit did indeed switch back into charge mode when a load was applied to the battery. They were out riding. It tapered the charge rate as the battery approached 14.3 volts, finally holding the battery at 14.3 while the absorption rate dropped to 0.3 amps. Manufacturers often disagree as to what the optimal float voltage is, but it’s generally 13.2 volts to 13.6 volts, depending on temperature and battery type. That seemed to be the case until we hooked the Tender to a battery that had just been charged with one of the competitors in this test. Battery Tender 6v 12v 4 Amp 10-Bank Shop Smart Charger. To be useful in charging depleted batteries, the unit should also have the ability to hold its output current high until the battery reaches gassing voltage. $27.12. 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. Sign up for a new account in our community. By Easy online ordering for the ones who get it done along with 24/7 customer service, free technical support & more. These gently rising and falling 2.4 amp pulses may discourage sulfation, but perhaps not to the degree of the more abrupt 4.4 amp pulses delivered by the AccuMate unit. We have no way of knowing the algorithm used, but a program which caused the unit to assume a certain temperature differential based on its own internal temperature would be the highest level of sophistication we’d expect to see at this price level. They do not have the intelligence to properly "maintain" a battery. It then cut back its output and gradually brought the battery back up to float voltage. It was then allowed to rest for 30 minutes before being drained at a rate of 4 amps for 10 minutes. While Deltran claims that the charge and float voltage is a function of the temperature compensation feature of the product, we believe that 13.2 to 13.4 volts would be a more appropriate float voltage for the 70-degree temperatures at test time. Put an old fashioned simple charger on it and it eventually charges it up... " each and every deltran Battery Tender will , regardless of it's size , charge a battery and maintain it". In this case, try a 'dumb charger'...like the old ones we used to use...set it for 2 amps (on a motorcycle battery)...and let it work for several hours..about 6 hours should be enough. #9. $34.99 800mA Battery Maintainer. In that particular case, the absorption mode lasted only ten minutes before the voltage rose to 14.4, and the steady green “charged” light came on. I guess this leads me to believe the cheap charger really never fully charged the battery and the bike is not charging it either. 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. The battery eventually reached 13.88 volts and went no higher. $. 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).

Then the units are supposed to switch to what’s called an absorption mode in which the battery can soak up the last bit of charge at a natural absorption rate that won’t result in excess gassing or heat. We would show up and have a bonfire, drink some beers and BS all night about bikes. Compare. 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. The Charger/Maintainer's multi-stage charging protocol ensures an optimal charge on all types of 6V, 12V, and Lithium-Ion vehicle batteries, and features a maintenance mode that's ideal for keeping stored batteries topped off between uses.

The always-on requirement, with no increase in electrical output capacity, caused the batteries on these bikes to be in a constant state of partial discharge. Instead, we sampled five of the most popular and readily available products, believing these most likely to be purchased by our readers. But with standard charger the 2 amp setting should show the battery getting at least 14.2 - 14.5 volts during the process. Our 19 amp-hour battery was fully charged between each test using the same charger/maintainer each time. 4 amp Battery Charger + Maintainer. A battery supplied with a constant current and held at an unwavering voltage that’s less than the gassing voltage will begin to sulfate after 60 days or so. We still burn wood, drink beers and BS all night. Should the units be required to supply more than a designed maximum current while in float (like if the ignition key is turned on), they all trigger into a new charge cycle. The GL1800’s alternator has the capacity to keep its battery from discharging at all engine speeds. Likewise, trickle chargers put out a constant charge regardless of battery voltage and can seriously overcharge if left unattended for extended periods. I put the battery on the bigger 55-10-2 amp charger and within a few hours it said fully charged.

Funny she says that about me too. However, that’s somewhat immaterial, as the current required to “float” a battery at a particular voltage will vary with the size and capacity of the battery and any parasitic loads present. I used my hobby charger yesterday to give it a charge, using "PB" mode. $54.99. I have a 2-10-50 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." version which does everything you will need for a low price. The auto parts store manager pointed out something I was unaware of and wanted some more opinions on the subject. It began charging at 0.9 amps with the battery voltage at 12.5 volts and slowly tapered the charge rate as the battery voltage increased. Does anyone remember what it was like before the internet. Overall, the Battery Tender ® Plus 021-0128 is the best battery maintainer that safely keeps the battery topped up at a safe storage voltage. AGM batteries are extremely slow to discharge. We rode for about 15 - 20 mins then parked the bike for a few days. When a 4-amp load was placed on the battery, the Tender didn’t respond as the other units had. That being the case, the bulk charge mode should hold a current at or close to the unit’s maximum output until the battery voltage is at or near gassing voltage. Current pulses peaked at 4.4 amps during charge and ranged from zero to 2.2 amps during float. And the battery tender 5. If the battery isn’t returned to a state of full charge, the crystals will harden, become permanent, and will shortly render the battery useless. What is the difference. During float, the Yuasa 1.5 maintained a 10-milliamp current and kept the battery at 13.29 volts. But if the bike is charging at 13.8 or so you are still in good shape. We first noticed it at an automotive product show in Las Vegas and were sent a sample for testing. In some cases, quite far. A 4-amp load across the battery terminals instantly caused the start of a new charge cycle.
