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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excelente compra *by I***. on 16 September 2023* 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 ### ⭐⭐⭐⭐⭐ Perfect for keeping NiCad and NiMH batteries healthy! *by A***N on 16 November 2022* The product manual is a bit daunting, but well written.

Robust product. ### ⭐⭐⭐⭐⭐ One of the best! *by K***D on 27 November 2023* Although I know how to treat rechargeable batteries, for years, we kept having trouble with them keeping the ability to charge. I don't know for sure if the problem was the chargers or my husband, but either way, we just couldn't make them work. After a few years of wasting money on alkalines and not being kind to the environment, I decided to try again. I researched the heck out of rechargeable batteries and chargers. I confirmed that I'd previously taken care of them correctly, then learned what makes some batteries and chargers better than others. I narrowed it down, then read a ton of reviews. This is the charger I chose. It's been a year since then, and I've been so happy with it! It has all the functions I wanted, it charges the types that I wanted, and it treats each battery separately. It's very clear about when a battery is fully charged. It's super easy to use. I attempted to refresh any NiMH batteries I still had lying around, and while most of them were too far gone, it did help me squeeze a little more life out of a few. If you've had difficulty with rechargeable batteries in the past, it might be worth reading up on their care a bit, but you don't need to look any further for a fantastic charger! The only reasons I can think of to go with something else are if you need to charge different types of batteries, or if it's important to you to be able to charge more than 4 batteries at once. A good smart charger can save you a lot of money, but as a bonus, this charger is very affordable. There may be other chargers out there that are as good as this one, but I'd be shocked if any are better in any objective sense. If you decide this particular one isn't for you, I highly recommend putting in the effort to make sure that the one you get is high quality, because so many appear to be good, but will require more effort from you and still shorten the life of your batteries in the long term. ## Frequently Bought Together - BT-C2400 Battery Charger Analyzer Tester for AA AAA NiMH NiCd Rechargeable Batteries - Eneloop Panasonic BK-3MCCA10FA AA 2100 Cycle Ni-MH Pre-Charged Rechargeable Batteries, 10-Battery Pack - Eneloop Panasonic BK-4MCCA10FA AAA 2100 Cycle Ni-MH Pre-Charged Rechargeable Batteries, 10-Battery Pack --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.it/products/589212096-opus-bt-c2400-battery-charger-analyzer-tester-for-aa-aaa](https://www.desertcart.it/products/589212096-opus-bt-c2400-battery-charger-analyzer-tester-for-aa-aaa) --- *Product available on Desertcart Italy* *Store origin: IT* *Last updated: 2026-09-22*
