Description

The Energizer Max 9V PP3 (also known as 6LR61) is a high-capacity alkaline battery designed for devices that draw moderate to high current over extended periods. Each battery measures 48.5mm × 26.5mm × 17.5mm and weighs approximately 45g. The two-pack includes two individual cells, each rated at 9V nominal voltage with a typical capacity of 500-600mAh depending on discharge rate.

These batteries are commonly used in smoke alarms, carbon monoxide detectors, wireless microphones, guitar effects pedals, multimeters, walkie-talkies and security system keypads — devices that require sustained voltage delivery rather than short bursts of high current. The Energizer Max 9V fits standard PP3 battery connectors with snap terminals and works in any device designed for alkaline 9V cells.

Energizer specifies a 10-year shelf life for the Max range, meaning batteries stored at room temperature retain at least 80% of their original capacity after a decade. The cells use a leak-resistant construction with an improved seal design that reduces the risk of electrolyte leakage during storage or use. Each battery carries Energizer branding on a white and red label with black and silver cap terminals.

Frequently Asked

How long do these batteries last in a smoke alarm?

In a typical mains-powered smoke alarm where the 9V battery acts as backup power, Energizer Max cells usually last 12-18 months before the low-battery warning chirp starts. Battery-only smoke alarms will drain the cell more quickly depending on how often the alarm tests itself and how many false alarms occur.

Can these be recharged?

No. Energizer Max 9V cells are primary alkaline batteries and cannot be recharged. Attempting to recharge an alkaline battery can cause leakage, rupture or fire. If you need rechargeable 9V power, look for NiMH rechargeable 9V cells instead.

What's the difference between PP3 and 6LR61?

PP3 and 6LR61 are two different naming conventions for the same battery format. PP3 is the IEC designation, 6LR61 is the ANSI designation. Both refer to the standard rectangular 9V alkaline cell with snap terminals that these Energizer Max batteries conform to.

How should unused batteries be stored?

Store 9V batteries in a cool, dry place at room temperature (15-25°C). Keep them in the original packaging until needed, and avoid storing them loose where the terminals could contact metal objects or other batteries, which can cause short-circuiting and discharge.
