EBL Rechargeable C Batteries 5000mAh Ni-MH C Size Battery, Pack of 8

There doesn’t seem to be very many objective, evidence based reviews here – so I thought I’d post my findings to help shed some light on these EBL rechargables. Since Amazon shows both D cell and C cell reviews here, I’ll combine mine here, too. I bought 20 D’s and 16 C’s for my vintage radio collection and a few Mag-Lights I have… There isn’t a real choice for name brand D and C cell rechargeable batteries (as there are for AA and AAA). This is why I chose the EBL D cell rated at 10,000 mAh, and the C cell rated at 5,000 mAh. Duracell, Eneloop, and LADDA do not sell rechargeable D and C cells at all. Energizer does, but these are merely glorified AA’s, as the capacity for both their D and C rechargeables are a meager 2,500 mAh. However, both Tenergy and Amazon Basics do offer rechargeable D and C with an advertised capacity of 10k and 5k mAh, like EBL does. For my testing I used two newly bought XTAR Dragon VP4 Plus battery charger/tester’s. This is one of the best out there as it is capable of charging/testing/refreshing anything from AAA to 18650 (and probably more), both NiMH and Lithium, in four independent bays. Another great feature of this charger/tester is that it’s wide enough for four D cells simultaneously. In test mode, this unit will top off the battery to fully charged, then discharge, and finally charge the battery from discharged to 100 percent. This enables the XTAR Dragon to calculate the number of mAh’s both charged, and more importantly, discharged. The discharged number of mAh’s is more important because this is the performance of the battery in use, or rather, how many mAh’s it “gives” versus “takes”. In addition to the mAH charge/discharge rate, the XTAR Dragon can also measure the output voltage and battery resistance in Ohms. This is only the first part of my testing, as I plan to update this review with future results in a year and beyond. All batteries were individually numbered so as to keep track of which one is which for future testing. Upon delivery of my brand new EBL D and C cell batteries, I ran them through the XTAR Dragon’s test mode. The D cells actual charge capacity varied from 10,000 mAh’s (for six of the 20) to a low of 7,216 mAh’s, which averaged out to 7,801 mAh’s (78.01% of advertised capacity). The discharge rate ranged from a high of 7,707 mAh’s to a low of 6,971 mAh’s, which averages out to 7,287 mAh (72.87% of advertised capacity). The C cells fared a little better. For the charge rate they ranged from a high of 4,546 mAh’s to a low of 4,164 mAh’s, which averages out to 4,303 mAh’s (86.1% of advertised capacity). The discharge rate ranged from a high of 4,553 mAh’s to a low of 4,026 mAh’s, which averages out to 4,203 mAh’s (84.09% of advertised capacity). As mentioned earlier, I numbered all of the batteries (20 D cell and 16 C cell) for future reference/testing. I hope to measure in the future how quickly or slowly the batteries discharge over time (percentage) without use for a year. I also hope to see how quickly the actual capacity degrades over time/charging cycles. As I have not bought or tested the Amazon Basic’s or Tenergy rechargeable D and C cell batteries, I cannot compare the EBL’s performance to them. But I would guess that they are probably manufactured in the same factory, or if not, under similar conditions. As such they are probably nearly identical to EBL batteries for performance, which makes EBL batteries a good value, indeed.

Great batteries as usual. I use them in a large wax electric flickering candle Work good, last long time, and charge easily!

These are to replace a set we have been using for several years and they finally won't hold a charge anymore. We really liked the other batteries so we replaced them with the same brand we had before. They have saved us a lot of money in the radio which has a built-in recharge system

These work very well. I use them in my flameless candles which are on a timer and I get weeks of use before having to recharge. They do take a little longer than expected to charge however I am not sure if that is the result of the batteries or the charger itself. I have repurchased for a family member who also enjoys flameless candles. Overall, I am very happy with this purchase and it feels good to have found a way to enjoy my candles without constantly spending money on batteries. It also feels very good to be supporting our environment.

Used them for 12 years and 100's of cycles. They hold ~4500mAh. I suggest to use good chargers like Opus 3100 or 3400 to unleash the potential of rechargable batteries. Need to refresh them from time to time and measure IR. Store them at 40f60% of their nominal capacity. And they will live.

Quality batteries

Very nice batteries for Led flashlights. NiMH is a very reliable chemistry. Have you ever heard of a Toyota Prius?

so far working great

Works well

Produto muito bom, de acordo com o informações passada. Supero minhas expectativas

Good. It has been 1.5 months and still not a single charge .👍👍

Nearly 3 year old battery delivered. It is dead and doesnot hold charge. Please refund the money

office use and good
