RS PRO LIR2450 3.6V Lithium Button Rechargeable Battery, 120mAh

Reduce your carbon footprint with this rechargeable button battery from RS PRO. As it can be re-used up to 500 times, you can rest assured you're reducing your waste output while keeping small devices reliably powered.
A lithium-ion composition gives the battery an exceptionally high energy density for more power. Its chemical make-up reduces its charging time while increasing its capacity, so the battery lasts longer in between charges. There's little risk of the component losing its power, even when standing unused for a period of time, thanks to its low discharge rate.
The small size and high capacity of this battery make it a good choice for industrial control equipment. It's also suitable to use in temperatures up to +45°C, so it can handle the heat of harsh factory conditions.
