EBL D Battery D Size Rechargeable Batteries 10,000mAh Ni-MH, Pack of 6 - ProCyco Technology

So far these seem to be working great. They last longer and seen to make my flashlight brighter. You do need to order a separate battery charger for these.

1 failed and will not hold a charge for very long. Used 6 of these EBL10000mah D Cells in my Realistic DX-440 shortwave radio. After a few hrs of use one of the batteries was completely drained and didn't have any voltage. The other 5 measured about 1.0V I really wanted to like these batteries but not so sure. UPDATE customer service stepped up and sent me 4 new D cell 10000mah batteries for a replacement. Top notch customer service. They stand behind their product. 2 thumbs up.

I have purchased AA, AAA, and now the D size batteries. I have never had an issue with any of the EBL rechargeable batteries. Some of the batteries are at least 5 years old and still holding a charge. They are a reliable power source.

Work as expected, but a drawn down in about 18 hours of usage in my particular radio. Work as expected however. Good purchase for the Elite Field Radio I purchased.

It's great to have rechargeable batteries that last a long time. I now have all sizes, except 9V, and I know I'll never have an issue with powering up any device. Make sure that you get the proper charger for the batteries you are using.

10,000 mh is a lot of staying power, but at 1.2 volts,flashlights may not be as bright.Last a long time

We have some EBLs that we've used for 15 years & are still going strong (~85% of charge now). We just needed to put more into use. Never any problems. Worthwhile investment!Care of Rechargables: We use a good slow charger -overnight charge & discharge & recharge b4 1st use to get full use of batteries.Tried Energizer, but they seem to have chronic fatigue: 1/4-1/3 gave up the ghost after 1st time, while the rest only charged 1000/2200mAhs. So much for saving money (waste of).Went back to EBL & very satisfied.

The media could not be loaded. I bought these EBL batteries in 2016, and some Tenergy batteries in 2013. It's 2023. Both sets of batteries no longer charge, except for maybe about 10% of them. Last year, they still mostly all charged. Given the math of 10 years vs 7 years, clearly the Tenergy batteries lasted longer.Having said that, I bought new EBL D rechargeable batteries because they were cheaper. Bad mistake. They didn't last 2+ hours on my lanterns before dimming. So, I was reading some reviews elsewhere for an EBL D size converter where it took one (1) AA battery into the shell of a D size part, allowing you to use an AA battery in a D slot. The reviews weren't good, but one mentioned item B081G5KSQ1, which allows three (3) AA batteries. I bought it to test, and here are the results.Test criteria:A random combination of three to eight (3-8) year old 6 AA 2,300 mAh rechargeable Energizer and 3 AA Panasonic Eneloop 2,100 mAh rechargeable batteries were used, in combination with item B081G5KSQ1 vs 6 brand spanking new D size rechargeable batteries. All batteries were tested in two brand new 1,000 lumens lantern, item B082HD5JDH.Results:Initially, the D EBL batteries were slightly brighter. I swapped the batteries and that made no difference for the batteries, meaning the issue isn't related to the lantern. After 2 hours, I started seeing dimming of the EBL. After 4 hours, the EBL D sized battery powered lantern was significantly dimmer. See my pictures.Verdict:3-8 year old rechargeable AA batteries significantly beat out brand spanking new EBL batteries.In fact, I posted a video of 7 year old EBL batteries no longer charging. They were kept indoors and used a few times only almost every summer except for COVID in 2020. Will these new EBL batteries last? So far they can't even beat AA batteries. I'm sending these back for a refund and buying AAs and using them with item B081G5KSQ1.
