Wondering about charging current: Honestly, I don't know enough about battery technology to know if I should be looking for another charger or not?

The 200mA charging current is just right for AAA cells. This corresponds to about 4 hour charge time (800mAh/200mA = 4h), or 0.25C, which is a perfectly safe charging rate for a SMART charger (like the BC-700). If you are in a hurry, you can even use the 500mA or 700mA setting of your BC-700. The '80mA' charging current is for DUMB charger - the type that charges at a low rate of 0.1C for 12-14 hours. Avoid that kind of junk chargers.

Anyone crack one open and see if this is anymore than a transformer and a couple diodes or is it an active charger that dials back the voltage or current when the battery is charged? Thanks. (I know it's only $8, but still wondering)

I looked up your charger # & found 1 on ebay for 19.98. Do not know which other chargers might work. First thing I would check to see if the batteries are good if you have not already done that. I hope that info helps some. Good luck

I'm actually using a spare one for that function now. HOWEVER, it will only charge items at the USB limit of 500mA per port. Most true chargers are capable of 700mA to 1000mA depending on the device.

if you use 2.4Ahr batts x 4 @ 1.2vdc each thats 4.8vdc 2.4Ahr.... (yes the charger actually uses 2.4vdc x 4.8Ahr) theres switching losses and controller losses in getting it up to 5vdc(20% ?) and your phones batt of 1.3Ahr also has losses in charging electronics(20% ?) as well as the battery losses itself(???)....... no one thought you could move and change power without loss.. did they? but still ~50% loss seems a little high... mabey it can charge it ~1.3 times? thats more like 20% loss on both devices as you might expect from cheap consumer goods

Alan: You'd have to check with the manufacturer because I'm not sure if the charging rate is the same for NiMH and Li-ion technologies. But I wouldn't use NiMH 9v batteries anyway because of their relatively high self-discharge rate. I want to be sure that when I need the battery, I won't find it dead.

This might not be a direct answer but I bought a separate charger for this battery because I read about many people complaining how the battery life had gotten shorter as a result of using lead acid chargers.

If you can find a USB AAA charger you like. I believe USB is 4.5V. 1.5V to 1.25V is AAA. My guess is two AAA batteries, at a time would be best since this is a low power charger.

There are so many chargers on the market it is difficult to specify which one you should buy. Just make sure you select one that is capable of charging a 3-cell LIPO battery (LIPO = lithium polymer). A "Cellpro 4S" is a good charger that will serve you well and the price won't break the bank.

The CTEK offers pulse charging, which is the coming RAGE in battery charging. Worth the extra $8 IMO I have built home made pulse chargers, and they are so much better for ALL types of batteries, except Lithium types.

Sorry, I can't shed any light on the subject, Brian. After ordering the charger I discovered the problem was with my battery not the charger - I returned the charger I purchased through Amazon. My battery had run too low to be charged using any charger. I had to take it to a golf cart service store and they got it up and running for me. The charger I had was perfectly OK.

Hey there, I have never tried to charged batteries of other brands. I thought they mention that it shouldn't charge with other brands..

Also a concern to me, however, I bought one... if I like it, will buy another.. it is less expensive than most batteries and charger alone.. so I can have one charging while using another.

Well, it has micro-USB output. So I suppose so...But you need to be careful, it has a pretty big current! It is intended for a larger capacity batteries, like external batter bank.I use it for that.It says 2.1 Amps of current!And you device needs to support that charge current of course.

I'm sorry, I don't have a certain answer. but it seems that would be a function of the charger more than the battery.

Yes better battery charger for sure, any upgrade will do. Stock charger charges in approximate 8 hrs. Extra batt would be a good idea as well. I have RPM bumpers for better crash tolerance. Other than that a solid truck out of the box!

I advise u not to charge it with a different charger b'couse it may cause defect on it . The battery can support a certain A or volts but it was designed to measure when it's full charged or empty , what i'm trying to say it's u can short the batery life if u use the wrong charger .
