so this charger takes apx 3 hrs to charge a 7.2 v 5000mah battery?

It charges my 7.2 5000 mah batteries for my remote controlled vehicles in less than half hour.

It can charge at 1.8 amps per hour, so 1800 mAh. In three hours, that would amount to 5400 mAh, so it should take just under 3 hours.

I really don't know, I have a bunch of toys and really don't use them. I guess I just like looking at them.

Both of my batteries arrived about 50% charged. Each took about 4-5 hours to fully charge (red LED goes off and blue is lit). It's just a very low power charger. A slow charge is supposed to be good for the batteries, but it's not good for me when I'm in a hurry. When traveling I'll charge them in the phone with a 2 amp charger.

the charger was a bit slow so i upgraded to an 800Ma power source and now i can charge in about 20 minutes and it will run for 20-30min

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.

500mA at 5V, not 2100mA as indicated -> You will have to calculate Watt from that, but is very low and slow compared to all the other chargers on the market!

I use a Battery Tender Junior, 750mA , takes about 6-8 hours to put a charge on the 12V 7AH battery. Time = amp hours / amps. Most likely takes less time than calculated because the battery carries residual charge. Your scenario, 500 mA, should take a little longer.

Assuming a perfect world, if you charge at 5 amps (5000 ma), it would take 1.06 hours.

Yes it's a Makita charger and 30 minute charge time! I bought one and two 3 amp batteries from amazon.

I'm not sure, but it us the slowest charger.It takes hours and hours. It isn't worth it.

Depends on what rate you have the charger sent at. The lower the amps the longer it will take, I suggest checking the voltage after 5hrs, should be 12.5 or higher when fully charged for a new battery.

Using a 1A charger, it took me about 7 hours to charge from empty. Keep in mind that when the battery is very low or near full capacity, the charging rate is less than 1A due to the design of lithium batteries.

Depends on battery capacity, 5000MaH 60C 3s lipo takes about 42min. It's a very good charger as it can charge two different battery types and capacities at once. One of the best chargers I ever bought.

Would you please define the stock charger? This is a 6 amp charger, if you are using a LiPo battery this will charge quickly. It charges my 8400 3s LiPo in about 85 minutes, pretty fast. If you are using a Nimh battery it will probably charge a bit faster than normal, but it depends on the capacity of the battery. Hope this helps!

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.

from a dead pack, I use my iPhone 5s charger and it takes roughly 6-7 hours

7.2V - should last 90 minutes on a charge (one of the reasons why I purchased this)

Both the chargers are self regulating depending on the battery voltage so the 5amp charger will charge faster if the battery voltage is low. If you discharge the battery to a low level the 5amp charger is the best solution if you don't discharge the battery to a low voltage condition the two amp charger is fine. To cover all conditions the 5amp is best. Make sure your battery and connector are compatible. Hope this helps
