Battery type

[Forgewright]

The Bounty Hunter Tracker 4 states: Use 9-volt ALKALINE batteries only. Not Heavy Duty batteries. Not ordinary Zinc-Carbon Batteries.

So...Can I use EBL 9V Batteries Li-ion 9 Volt Rechargeable Batteries?
I searched for rechargeable alkaline batteries at Amazon and these popped up in the search. I know zip about batteries.

Should be fine. "Heavy duty" and carbon-zinc batteries are usually crap quality that don't last long and people then blame the detector, ergo the warning. The EBL battery looks pretty good.
