This is the only battery we recommend using in the Wind Instrument;  it is safe and extensively-tested.  The full battery specifications are listed on the Technical Specifications page.  Unlike standard NiMH and NiCd rechargeable batteries and non-rechargeable alkaline batteries, this battery has an exceptional range of operating temperatures for outdoor use, from -40 degrees Celsius to +85 degrees Celsius (-40 degrees F to 185 degrees F).  With proper care and charging it also has an extremely low self-discharge rate, losing only 1% power per month when in storage, practically nothing.  LFP is a newer type of lithium battery, with a longer lifespan of charge cycles than other lithium batteries (and far longer than traditional lead-acid rechargeable batteries).

We do not recommend using other batteries as replacements because single-cell lithium batteries are sometimes poorly specified by their manufacturers.  Also the origin country and manufacturer may not be clear, which makes it difficult to establish safety levels.   Single-cell batteries have no safety circuits built in, and can have wildly varying degrees of manufacturing tolerances.  That can lead to batteries that go dead for no reason, or dangerous flaws such as explosions or fires in some cases.  That’s why it is best to use our battery, and why use of other batteries voids the warranty on your Wind Instrument.

The battery above comes with the connector wires for an easy replacement.  You should not attempt to solder wires onto a battery yourself, since the heat to melt the solder raises the temperature in the cell above specified levels and can damage the battery. With this connector there is no latch, but it may be pushed in tightly and may require some prying or small pliers to gently pull apart.
