ER651620 LTC-5PN 3.6V Lithium Thionyl Chloride (Prismatic Cell with pins)


Type: Lithium Thionyl Chloride. Voltage: 3.6 V (or 3.5 V).

Height: 7.0 mm. Depth: 16.8 mm. Length: 20.4 mm (23.8 mm incl pins).

Termination: four PCB pins (tinned nickel).

Price: 9.49 each. 8.92 each if you buy two or more. Postage and packing included.

Replaces: LTC-5PN, EF651620, BiPower BL-5PN, Eagle Picher LTC-5PN, Keeper II LTC-5PN, Ef651620, EF651620.

This LTC-5PN or ER651620 3V Lithium battery replaces EF651620, BiPower BL-5PN, Eagle Picher LTC-5PN, Keeper II LTC-5PN, Ef651620, EF651620 batteries and many others.

The LTC-5PN or ER651620 Prismatic Cell has four PCB pins that protrude 7.6 mm. The central pin is the positive terminal, the two outer pins are the negative terminals.

This LTC-5PN or ER651620 Prismatic Cell is widely used for CMOS memory backup in personal computers, and for many other electronics applications.

The size of this LTC-5PN or ER651620 Prismatic Cell is occasionally referred to as EF651620 or BL-5PN.

This LTC-5PN or ER651620 is a high-capacity prismatic-type Primary Lithium Battery with a  laser-sealed can. The LTC-5PN or ER651620 uses Lithium Thionyl Chloride chemistry for a high energy density and a wide operating temperature range of -55C to + 85C. Self discharge is low at less than 1% per annum at 20C, giving an effective shelf life of 10 years.

Other terminations are available in quantities but it is easy to derive common terminations from the stocked four-pin LTC-5PN. To derive the two-pin LTC-5PN-S2, simply remove the two 'back legs' leaving a two pins - a bent positive pin and a bent negative pin. To derive the straight pin LTC-5PN-S4 just go one step further and straighten the two pins. The LTC-5PN is a robust battery and is well able to survive these modifications.

With such a long shelf life, why not buy two or more packs of the LTC-5PN or ER651620. Take advantage of our reduced price and make sure you are not left in the lurch next time your battery runs out.
