  • Battery TypeLithium Polymer
  • Original Varta brand ensures reliable quality
  • 6V 150mAh NiMH chemistry delivers steady backup power
  • 4-pin Mempac connector fits RTC memory slots directly
  • Five-cell pack supplies spares for multiple systems
  • Replaces 55615 703 012 and compatible part numbers

Five-pack Varta micro batteries

This five-pack supplies Varta 55615-703-012 micro batteries built for RTC memory backup in laptops and desktop PCs. Each cell delivers 3.6 V and 150 mAh in a sealed NiMH button format. The pack suits repair technicians and IT teams who maintain multiple machines.

Four-pin Mempac connector

The decisive specification is the four-pin Mempac connector that mates directly with the motherboard header. Buyers whose boards use a two-pin or soldered coin cell cannot use this part. Verify the header layout before ordering.

150 mAh capacity for CMOS duties

At 150 mAh the cells comfortably maintain CMOS settings and real-time clocks for years of typical standby time. They are not intended for high-drain loads or as main system power. Systems with unusually leaky RTC rails may exhaust the reserve sooner.

Questions about this item

What does the 150 mAh rating mean for real-time clock backup time?

The 150 mAh capacity typically powers a laptop RTC or CMOS memory for several years of standby before needing recharge.

How does the 4-pin Mempac connector limit compatibility?

The 4-pin Mempac layout only fits boards wired for that exact pinout; it will not mate with 2-pin or 3-pin CMOS headers.

What clearance does the button-cell body need on the motherboard?

The sealed microbattery measures roughly 12 mm diameter and 5 mm height, so allow that footprint plus the 4-pin header vertical space.
