What is the charging rate for this battery? I have 3 wired together .do I charged it at14.3 or 14.7 as per my CTEK Charger.

I have two 12V22AH batteries wired in series producing 24 volts. It all depends what your using the batteries for. I charge mine on a 2 Amp.24 Volts charger. It may take more but certainly not the charge your suggesting. Be careful. You may explode the batteries or ruin them. How are you wiring them? Series or parallel?

I charged mine the first time for 8 hours (overnight) and have had to charge it two other times in a four month period. How are you able to tell you have only 15%?

On pg 13 of the English section of the manual it says "All types of lead-acid batteries (Wet, Maintenance Free, AGM and most GEL)." On the cover it says "For lead-acid batteries 14-150 Ah". It repeats that restriction in the IMPORTANT SAFETY INSTRUCTIONS and adds "do not use for any other purpose." In the PERSONAL PRECAUTIONS section, it says "Use charger for charging a LEAD-ACID battery only." If I were you I would check the CTEK website and look for a different charger, send them an inquiry, or call them. It appears to me the answer must be no. But I am no expert.

I charged the battery for about 14 hrs. and the battery only lasted for about 3 hrs. and it was dead. So after three more attempts to charge it and getting the same result, I gave up. I hope this answers you question.

No battery is fully charged, unless you buy it at a store, have them charge it overnight and pick it up the next day. This battery is a good one for the money in my opinion and should last a long time, but time will tell as I have only had it five months. And No it was not fully charged and I would say it was so discharged on arrival that waiting to recharge it much longer may have already shortened its life. Buy a CTek 3300 battery charger they are the best and has made some of my batteries I have last 10 years.

It says it will charge everything from 7.2 - 18V. I use it for 14.4 volts with no problem. On the bottom it says all 14.4 volts. So it should be good for yours. I'm happy with it.

Be careful as there are two charger models for the 14.4. The one shown in the picture will work with the older model battery as I have found out. The charger pictured will charge your batteries, presuming your batteries are still good for the remaining cycles before they need repair. I'm not sure you can get new 14.4 batteries today. It appears everything has gone to 18+ or larger batteries.

My charger, a ThruNite MCCC-4, outputs a charging level of 4.2v. When the battery reaches this level, shown onLCD panel, it shuts off, fully charged. The battery "likes" to hold an operating voltage of 3.5, so using a charging voltage of 3.8 would be conservative, and certainly safe. These batteries are very robust, and will not take more than they're designed for.

Yep...I always do when it gets down to about 10-15%...you can also charge the other battery in the wall charger and plug another device into the charger through USB and charge that one as well. These batteries hold their charge well.

The maximum recommended charging voltage is 14.7V. Don't know what the minimum is.

I hope you didn't already buy this. I bought it and left my battery in it for 24 hrs and when I checked out it was only on 1% ! I'm not sure if it's suppose to let you know if it's charged or not b/c mine didn't come with instructions but my charger didn't let me know !!

At 14 volts you probably don't need this. 14 volts is even lower than some charging systems which would go to 14.4 volts during a saturation mode.

these batteries take some time to charge. It is the nature of the beast that the time extends as the charge reaches higher capacity. The last 10% can take as long as the first 70%. I find the percentage on any battery as more of a guideline than a definitive measure. I wouldn't say you have a problem with the product just yet.

My 1413 charger charges this battery just fine. I'm very satisfied with this battery. It's a good deal too Russell. I bought 2. No regrets.

I charge mine with the Anker 14watt solar panel. You can also charge it using a usb cord. Just connect it to a computer or any other usb port that has the ability to charge. Great battery.

Not to be a "brand-hog" but I would recommend simply purchasing a Tenergy or Tenergy-recommended charger in order to get the most out of these batteries. Mine are over three (3) years old and still like new!
