Right for the Zen-O

This is the full-size Zen-O battery (12-cell). The smaller Zen-O Lite uses a different 8-cell pack.

Hours per charge

Up to about 4 hours per charge at lower settings — carry a spare and the Zen-O holds two for extended range.

Fast recharge

Back to full in roughly 3 to 4 hours, so you spend less time tethered to a charger.

Details

What's included

One genuine GCE Zen-O 12-cell battery (part RS-00501). Charges through the Zen-O with AC or DC power; power supplies and external chargers are sold separately.

Why genuine matters

A genuine GCE pack has the matched 12-cell chemistry, battery-management, and latch the Zen-O expects — for full rated runtime, safe charging, and a secure fit in the bay.

Frequently asked questions

Does this fit the Zen-O Lite?

No. This 12-cell RS-00501 is for the full-size GCE Zen-O. The Zen-O Lite uses a separate 8-cell battery (RS-00601), which we also carry.

How long does it last per charge?

Up to about 4 hours per charge at lower flow settings, per the manufacturer; higher settings draw more power and reduce runtime. Ask us and we'll estimate for your setting.

Can I run two batteries?

Yes — the Zen-O accepts two batteries at once, so a second pack roughly extends your time between wall charges.

Is it genuine?

Yes, it's a genuine GCE Zen-O battery. It ships free in the USA.

Can I take it on a plane?

It's a lithium-ion pack, so airline lithium-battery rules apply to spares in the cabin. Confirm your airline's policy before flying.
