ARE-A4 Battery Charger and 3500 Battery Bundle

Batteries are Bomb and the Charger is too

These batteries last such a long time in the lights Fenix has. That probably isn't really because of the batteries, but the fact that the devices get hot and batteries do not is quite impressive. The charger is amazing. You can toggle the voltage, charging current, and elapsed charge time for each batter independently, it lists the batter type for each battery independently, and there is an indicator that shows how well charged each of the batteries are. The charger doesn't overheat, has no loud/noticeable fan, and appears to have good thermal management. The contacts are really well made and, likely for that reason, it was able to charge some Energizer NiCd batteries that wouldn't charge on my Energizer charger.

The product was everything I needed. I have plenty of charged batteries for my flashlite. Don't have to worry about running out.

Great product
