Review: Excelente compra - Tiene la función para descargar a 0% es muy útil para una carga full y las pilas que duraban con poca carga, parece ser que las repara
Review: Perfect for keeping NiCad and NiMH batteries healthy! - The product manual is a bit daunting, but well written. Once the features are understood, I found that pressing buttons was a good way to find out how to select the modes and achieve the desired result. The LCD display is illuminated and clear, showing the progress of the selected operation. Robust product.

## Questions & Answers

**Q: What is the difference between this BT-C2400 with the BT-C2000 unit?**
A: I have the BT-C2400 and it only charges the AA and AAA NiMh batteries. I don’t know what the BT-C2000 unit does.

**Q: with the opus bt c2400 what reading tells me that the battery is dead and no longer able to hold a charge worth using in my speed light flash?**
A: I don't know if it has a "dead" battery code.  However, it will tell you what the current charge is in mAH.  For example my AA batteries are 2300 mAH.  However, after battery charges the display will tell me that it was able to charge the batteries to 1800 mAH.  I assume when it hits below 900 mAH (50%), it is time to change them out.  There is a refresh+charge mode.  I have done this a couple of times and it made a difference.  i.e current full charge is 1000 mAH, after refresh full charge is 1800mAH.  Hope this helps.

**Q: Is there any other difference between the bt-c 2400 and the  3400 besides the ability for the 3400 to charge lithium batteries? thanks**
A: The ability to charge Li-ion for the C3400 is the big difference. They use basically the same charge algorithms for NiMH cells. The C3400 also has greater charge current capability. It can charge at 2000 mA on two channels.

**Q: Does it allow to charge nearly drained batteries (with the low voltage left, less than 0.5v) or still reports "null" on them, like its predecessors?**
A: You can put 0V batteries into a dumb charger, and if they can take a charge, 10 - 15 mins should be sufficient to put in enough charge to be recognized by a smart charger.

However, more often than not, batteries measuring 0V will have some issues, and even if they can be charged up, they may not be able to hold a useful amount of charge.

### ⭐⭐⭐⭐⭐ Which Smart Charger? Either this or the Maha C9000.
*by R***C on 29 September 2015*

** Received September 28, 2015 from Amazon Fulfillment with 2.2 firmware. ** This charger is awesome. It operates more similarly to LaCrosse chargers than the Maha C9000. I have two rechargeable battery intensive hobbies... one is small scale RC Car racing, and the other is photography. I'm constantly charging batteries for one of the two things and as of receiving this one I now own three smart chargers: This one, the Maha C9000, and the Maha C801D. The C801D is a very basic smart charger in comparison and I primarily use it when I need to charge several batteries at once rather than when I want to try to condition and restore a cell so this will mainly be a review in comparison to the C9000. The tl;dr version is, both the Maha C9000 and this Opus BT-C2400 have their strong points and for people that have a need to charge a lot of batteries, I can recommend both for different situations. Get this one if you'll ever be using older batteries as it has a better chance of restoring them. Get the Maha C9000 if you don't use old batteries and have the need to charge cells quicker. ----- The main point I really like about that BT-C2400 charger is that it wont give up on your old batteries that have seen better days. The Maha C9000 does a check when you insert a battery and if it detects too much resistance, it displays "HIGH" and refuses to charge a cell. The BT-C2400 however will attempt to charge the cell to try to restore it (it states in the manual that it will probably charge at a reduced rate to what you select if it detects really high resistance). I was able to restore some power to some old cells that had sat around since 2010. Though the resistance is too high for them to be used for RC racing, they can be used for slower drain items like remotes / controllers / tablet pens. The main point for the Maha C9000 is the ability to charge on all 4 slots at up to 2000 mAh where you're limited to half of that with the Opus (70% of it if you're only charging two batteries on the outer slots). If you need to charge something faster and still want the monitoring functions of a smart charger, the C9000 is the better option. I also like the break in mode of the C9000 for a fresh pack of batteries. You can use the refresh function similarly with the Opus, but even though you have to push more buttons on the Maha I like the break in interface more for it. If you're going to be working with older cells and want to try to restore them to get some use out of them, I'd go for this one over the C9000. The cost is lower and it will service older batteries without a problem where the Maha C9000 might refuse them. If you'll be working with newer batteries mostly and value the higher charge rate, the Maha C9000 is still a tried and tested smart charger and works really well. The Opus BT-3400 is another option, but it does the same thing as this one except it supports other types of batteries. It's really only worth the extra money if you think you'll be using lithium rechargeables. My hobbies only involve NiMH so it wasn't worth the extra $20 to step up. The final alternative is the LaCrosse chargers. I used to own their BC-700 but it just died on me at random so I don't have the best impression of longevity for LaCrosse chargers. Currently, the BC-700 is overpriced for what it does. The Opus BT-C2400 does everything the BC-700 does and more... in fact it's more comparable to the higher end BC-1000 in charging speed while still winning on features and price. To it's credit though, the BC-1000 does come with a case, two sets of batteries, and adapters so that offsets the price difference. At this point, I don't think I could seriously recommend any of the LaCrosse BC-700 at all. The BT-C2400 is simply better and costs less to boot. The BC-1000 should only be an option if you need the adapters to C or D, or if you really really need the smaller footprint of the LaCrosse charger (you don't). So I can really only recommend the Opus or the Maha right now. If you have the money, both have their positive points and I'd get one of each. For everyone else though, unless the faster charging speed is really necessary for you, this is probably the most well rounded smart charger on the market. It's also refreshing to see that they are always updating hardware and firmware so I think they are likely to stand behind their product longer.
