I've got some AA 3500mah batteries. They say standard charge 16hours at 350ma. Will this unit work?

You should be able to charge these batteries, but get ready to learn you wasted money for crappy batteries... Most of the "high power" batteries I came across are fake and not holding more than half charge they promise. Only brand name batteries like Eneloop and Duracell were performed exactly as specified. Another problem with off brand batteries is self-discharge. I had several batteries losing up to 70% of charge within one month. On the bright side with this charger you will find-out what batteries you can trust. Good luck!

3500mah AA rechargeables? That's very high - my AA Eneloops might reach 2250 or so..... but anyway - yes this unit should work fine. You can adjust the charge to be quicker if you want. I charge my AA Eneloops at about 400 and they're done within 8 hours. I love this charger.

if you can smell the battery it probably is bad or your overcharging it.. How long you should charge your battery is totally dependant upon how many milliamps or mA it has. If it has 1400mA it will charge much faster than a battery with 2800mA. Now look at your converter, you will notice several things on the sticker that will be affixed to it. We are looking for the output rating on it specifically. It usually says something like "OUTPUT: DC 8.4v 300mA" but changes from brand to brand and model to model. See that 300mA on the charge? That's how many mA its charges per hour so if you have a 1500mA battery and a 300mA charger its just simple math from this point.So it will take 5 hours total to charge a completely dead/new battery to its full capacity. You simply divide the mA on the charge to the mA of your battery and you will get the time it should take to fully charge a completely drained battery. This does mean to set it and forget it though. In most cases your battery has already been charged once even if still new for quality control purposes so you really need to keep an eye on your battery still.

Most any good charger will work. Check to see if it has a special setting for AGM batteries. If so use it.

As long as they are rechargeable nickle metal hydride (Ni-MH also called MIMH) they will work no matter what they cost. The more milliamp hours (mAh) they have the longer they will last after charging, but higher mAh batteries will take longer to charge. I put 2500 mAh Energizer brand rechargeables in my solar charger and left it out in the sun for about 6 houes and the cheap little battery tester meter I have was in the green. I don't know if it was fully charged or alomost full. I bought this for emergencies like after a hurricane, so I only tested it once and put it away.

Not sure about your batteries,But works good on my 2 golf cart batteries hooked to getter to make 12volt.it will charge raped charge 14.5 or so

That depends somewhat on the charger. I have a very compact Energizer charger (#CHDC8) that will charge 4 AA's in about two hours. Some quick chargers are faster, but I've been told fast charging is not good for the batteries.

Yes should work fine. However be careful not to over discharge the battery . Normally you would want a deep cycle type of battery. Their big and heavy. Just be careful not to take discharge below 11.5 volts

Refer to your current charger. This unit will work if the your current units provides 19.5V and equal to or less than 4.62A.

The batteries should be about the same, the "a" in this case indicates a revised, probably improved, version. This charger will work for both.

I have 6 12 V 35AH batteries. I wish I had one more panel to charge in one 5 hr period. Here are my calculations. Assuming a 50% charge, each battery needs about 17 AH to recharge. 2 panels each put out about 8 amps. so 8 hrs X 16 amps is 128 AH. 128 / 17 is about 7. So my answer would be 7 35AH batteries.

This charger is for a 24volt OFF-BOARD charging system with standard 3-prong XLR OFF-BOARD connection that charges two AGM batteries. 55ah would be ok. Battery Buys 800-790-9941

That should be fine. The charger was 'specificly' designed for AGM batteries. But, it will work on any battery type. google "agm battery" if you're curious

Yes, it will work fine. The milliampere /hours of the battery only have to do with power capacity ie battery life. If the voltage is the same and the battery fits bigger mAh is better. Make sure the new one is the rechargable type before you attempt to recharge it.

It will charge at 250mA. This should charge most batteries in 8 hours. However, when you plug it in it charges for 10 hours and then shuts off. Period. If you put in fully charged batteries it will still charge them for 10 hours. If you plug it in and then add a battery 8 hours later, that battery will only charge for 2 hours before it shuts off.

You are mixing watt hours with milli amp hours in your question. If the battery is made for the product it should work okay. The current rating of the battery is not very critical. If the new battery is of a higher current rating it will take a bit longer to charge.

I would have to look it up in the manual. Some deep cycle batteries like AGM's require a higher than standard voltage for charging. Perhaps you can download the Owners Manual pdf online.

Well yea, use a battery charger , or a deep cycle charger with a max of 35 amp .Most deep cycle batteries use a slow charge rate anyway which is a lower amp charger.Just keep the amp below 30 to 35 amp @ 12 volt. This is not a 24 or more system charger.
