ARB-L21-5000 is a high-capacity 21700 Li-ion rechargeable battery built for more power and longer runtimes. Additional features include a protection circuit in the anode to help prevent short circuits, over charge/discharge and over heating. Pressure relief vents which expel waste gas in the rare case of an internal short circuit preventing an explosion. Battery capacity up to 5000mAh. 500 charging cycles. Currently recommended for the HT18, PD36R, TK22 V2.0, and TK22 UE. The TK22 V2.0 and TK22UE require a charger to charge the battery. Important Note: THIS BATTERY IS NOT COMPATIBLE WITH 18650 FLASHLIGHTS OR OLDER STYLE CHARGERS. COMPATIBLE CHARGERS ARE THE ARE-A2, ARE-A4, ARE-D1 OR ARE-D2.
Took 3 hours to fully charge the battery, have not charged it so far. I use it on a daily basis and the PD36R shines through the darkness. Very good purchase.

Always like a back up battery just in case. The cost is minimal when ordering and can’t knock the convenience of ordering both at the same time.

Always good to have a spare battery. A real powerhouse at 5000 mAh. Charged pretty quickly using the usb-c of the PD36R.
