Panasonic eneloop pro AA 2550mAh Reviews

Long charge time, but many flashes on a charge.

They take ages to charge, but I'm assuming that's due to the nature of the cell type (NiMH). With how many flashes I'm able to get on a single charge, it's not really a big deal, just something to prepare for if you buy this product. Charge long, long before you need them. Two of the batteries also had a little nick on the end of the encasement/covering, and I do worry that might require earlier replacement than they might have needed if they'd arrived in pristine condition; this was not a shipping issue, this was a manufacturing/quality control issue. Otherwise, the batteries themselves work fine. The charger is alright, but it also showed up slightly scratched in the box, though that is cosmetic only. Again, this was a manufacturing/QC issue.

Great batteries, legendary Panasonic quality

They are lithium ion batteries, so hard to say too much more than that, other than the charger is very nice, and everything feels premium. Have come to expect nothing less from Panasonic, their products are always top notch!
