Athlon Optics Cronus ATS/ATS PRO 2-Pack Battery

A Cronus ATS PRO thermal scope runs on its external battery first and switches to the built-in one when that runs out, so a charged spare stretches a night out. The Athlon Optics Cronus ATS/ATS PRO 2-Pack Battery is a pair of spare external batteries for the Cronus ATS and ATS PRO thermal scopes.

Key Features

• Two rechargeable lithium-ion batteries, each rated 3.6 V and 3.15 Ah (11.34 Wh), with a 4.2 V charge voltage.
• External battery first: the scope draws on the external battery and moves to its built-in battery when the external one is flat.
• Charging: charge them in the battery charger that comes with an ATS PRO scope, or in the scope over USB-C, which charges both its internal and external batteries.
• The built-in battery needs its own charge: the external battery does not charge it, and the scope won't switch on from the external battery alone if the built-in one is completely flat. Use the scope's USB-C power adapter then.

Ideal For

• Owners of a Cronus ATS or ATS PRO thermal scope who want charged spares on hand for long sits.
• A second set, so one pair charges while the other is in the field.

Accessories & Compatibility

• Cronus ATS PRO scopes we carry. The Cronus ATS PRO 35-400, 50-640, 35L-400, 50L-640, 25P-250 and 35P-400 each come with two external batteries and a battery charger.
