About this replacement
Ray Enterprises Ray Super Remote / RC100 — 3.8V Li-Polymer Replacement Battery (RB00101)
This is a 3.8V, 2950mAh Li-Polymer replacement battery for the Ray Enterprises Ray Super Remote and RC100. It carries OEM part number RB00101 and slots into the original battery compartment. When the factory battery depletes and the remote stops responding, this cell restores full function.
- Ray Super Remote and RC100 compatibility: Both the Ray Super Remote and RC100 share the same battery bay dimensions and 3.8V supply rail. The RB00101 footprint — 68.60 x 48.70 x 5.54mm — matches both housings without modification. No adapters, no trimming.
- Bench tested on actual hardware: We cycled this cell through charge and discharge on a Li-Polymer test rig. The battery hit rated capacity within two cycles, and the protection circuit tripped correctly at low-voltage cutoff without needing a manual reset.
- Li-Polymer flex-cell handling: Do not fold, puncture, or compress the pouch cell during installation. Li-Polymer cells use a flexible casing — unlike rigid cylindrical cells, a dented or creased pouch can develop an internal short. Lay it flat when seating it into the compartment.
Why the Ray Super Remote stops responding even with a new battery installed
The most common cause is reversed polarity on installation. The RB00101 is a Li-Polymer pouch cell with a JST-style connector, and the plug seats in one orientation only — but some housings allow forcing it backwards. If the remote shows no response immediately after install, unplug the connector, flip it 180 degrees, and reseat. Confirm the remote responds at normal distance before closing the housing.
Ray Super Remote needing to be held much closer to the TV than before
This symptom points to the battery voltage dropping below the IR LED's minimum trigger threshold. The LED fires, but at reduced intensity — so it only registers at close range. A cell sitting at 3.5V or below on a 3.8V nominal circuit is the usual cause. Check cell voltage with a multimeter: anything under 3.6V at rest means the battery needs replacing, not recharging.
