The SLIGC115 battery is an integrated power unit designed for early 2000s mobile devices, specifically the Motorola C115 “flip phone” released in 2004. This 3.7V lithium-ion pack delivers 3700mAh capacity through a non-removable design, supporting basic call/text functionality with multi-day standby times. Unlike modern smartphone batteries, it lacks fast-charging capabilities but features basic protection circuits for overvoltage prevention.
Why choose the SLIGC115 battery for legacy devices?
This energy-dense cell was engineered for compact feature phones requiring minimal maintenance. Its aluminum casing and robust terminals provided vibration resistance crucial for early mobile devices used in vehicles or industrial environments. Pro Tip: Replacement requires full disassembly—use plastic pry tools to avoid short-circuiting the unprotected cell.
Unlike contemporary batteries with micro-USB charging, the SLIGC115 uses a proprietary 4-pin connector. For example, Motorola paired it with 5W AC adapters requiring 4+ hours for full charging. Transitionally, while obsolete for smartphones, these cells remain relevant for maintaining vintage telecom equipment where modern battery retrofitting proves impractical.
How does the SLIGC115 compare to modern equivalents?
| Parameter | SLIGC115 | Li-Po Smartphone Battery |
|---|---|---|
| Energy Density | 260 Wh/L | 700+ Wh/L |
| Charge Cycles | 300 | 500-1000 |
| Protection Circuits | Basic OVP | Multi-layer BMS |
With only basic overvoltage protection, the SLIGC115 lacks thermal sensors or balancing found in modern packs. Practically speaking, it’s akin to comparing mechanical wristwatches to smartwatches—both tell time, but with radically different complexity. Transitionally, refurbished units still power vintage phone collectors’ devices, though third-party clones now use safer LiFePO4 chemistry.

FAQs
Only with compatible voltage/connectors—its 3.7V output works for similar-era devices, but proprietary interfaces limit cross-compatibility without custom adapters.

Is fast charging possible with SLIGC115?
No—its 0.5C charge rating (1.85A max) and basic circuitry can’t handle modern PD/QC protocols. Use original 5W chargers to prevent thermal stress.
