Default Re: Has anyone had issues with Rayovac Alkaline batteries leaking

The cell voltage is based on the chemicals used in the battery. Lithium has a high potential, you'll usually see 3.7-4V and here Energizer did get it down using iron-disulfide.

I mentioned the 1.8V just to check the device can take it, it's the worst case and only for a short time. I think it would be worse for two battery devices seeing 3.6V as many IC's are rated ~3.6V max. before the higher classes.
Fluke does not mind it, the voltage regulators drop it down.
The 9V L522 is ~8.4V nominal and 9V peak.

Energizer ultimate lithium are guaranteed to not leak at all: Energizer battery leakage policy
But again, you have to ship the device to them which is gross.
