CARBON NEUTRAL RECHARGEABLE BATTERIES

COAST has achieved CarbonNeutral® product certification for our Zithion-X AAA Rechargeable Batteries (4, 8 and 12 pack) and Zithion-X AA Rechargeable Batteries (4, 8 and 12 pack) in accordance with The CarbonNeutral Protocol, the leading global framework for carbon neutrality.

We tested COAST 1 x AA Zithion-X batteries along with COAST Constant Current 1 x AA, and COAST NiMH 1 x AA batteries in a COAST HX5 Flashlight. The COAST Zithion-X batteries had a runtime of 6 hours and 16 minutes. The COAST Constant Current batteries had a runtime of 1 hour and 20 minutes. The COAST NiMH batteries had a runtime of 4 hours and 29 minutes.
COAST® internal testing versus COAST® branded batteries.  In every product test we conducted, the COAST® Zithion-X® AA battery outperformed COAST® constant current lithium AA batteries in terms of runtime performance.  When testing batteries in the COAST® PM200 work light using 3 x AA batteries, COAST® Zithion-X® AA batteries had an average runtime of 8 hours and 59 minutes.  On the same PM200 work light, COAST® constant current AA batteries had an average runtime of 2 hours and 22 minutes and COAST® NiMH AA had an average runtime of 5 hours and 30 minutes.   When testing batteries in the COAST® EAL13 lantern using 4 x AA batteries, COAST® Zithion-X® AA batteries had an average runtime of 4 hours and 46 minutes.  On the same EAL13 lantern, NiMH AA batteries from COAST® had an average runtime of 3 hours and 9 minutes.
We tested COAST® 3 x AAA Zithion-X® batteries and COAST® Constant Current 3 x AAA batteries in a COAST® FL75R. At the 45 second mark of testing, the headlamp containing COAST® Constant Current batteries began to flicker, with drastic lumen fluctuation visible. The COAST® Zithion-X® batteries showed no flickering and continued to run for 2 hours and 10 minutes.
Based on multiple internal tests on COAST® Zithion-X® batteries, the average time to a full charge was under 2 hours and 30 minutes on the COAST® Zithion-X® AA batteries and under 1 hour and 15 minutes on the COAST® Zithion-X® AAA batteries.
