Hi,

3 of my -not too old- Eneloop pros are dead. See pictures. Have 32 of the pro`s (16 bought 2023 and 16 bought 2024) and 32 of "normal white" eneloops (arround +10 years old). Never ever had a issue with the old white ones. All still working.

All of the Pros only slightly used on 2 dive trips with not too many charging cycles. At home I charge with Youshiko intelligent charger. During last dive trip I used EBL chargers recommended and supplied by Retra. Realized that sometimes the Pros during charge in EBL got extrem hot. Accus got no contact with saltwater etc.. Any ideas what happen?

Thanks Markus

Woah! They don’t look good.

I’m using EBL USB chargers all the time for my Eneloops - Pro and White. Had all the batteries for some years and no issues at all.

im using Panasonic BQ-CC55 chargers. I did have one or two dead batteries a long time ago, but not in recent years. I allways travel with a few extra batteries.

I do try to keep the eneloops bundled in pairs of 4, Never had issues like in your pictures myself

For the Retra users.. I can recommend for travelling the BQ-CC63 8 AA slim, light I love this charger

I use AA Eneloop pro... no such problems but some had some problems allways had error loading it Iost more than 15% of it in the past 3 or 4 years.

I, too, have used both the standard Envelops and the pros, with BQ-CC55 chargers and Inon strobes. I've had no issues.
