Replacement battery for TI calculators
This lithium-ion cell replaces the original power pack in TI-Nspire CX CAS, TI-Nspire CAS Toucad, N2/AC/2L1/A and TI-84 Plus C Silver Edition graphing calculators. It delivers 3.7 V and 1300 mAh capacity, matching the factory voltage and runtime specifications. The pack measures 53.74 x 47.9 x 5.0 mm and weighs 51.0 g, fitting the existing battery compartment without modification.
Interface and protection limits
The cell uses the calculator's proprietary connector and charging circuitry, so it charges only inside the host device or a Texas Instruments approved cradle. Built-in circuitry provides overcharge, over-discharge, over-voltage and short-circuit protection, preventing damage from fault conditions. No external balance lead or separate charger is supported; the calculator manages all charge termination and safety logic.
Capacity and runtime headroom
At 4.81 Wh the pack supplies enough energy for a full day of typical classroom or exam use on a single charge. Heavy graphing, continuous backlight or frequent wireless communication will reduce runtime proportionally. The 1300 mAh rating leaves no margin for capacity-hungry accessories; users needing longer untethered sessions must recharge between classes.
