Replacement battery cartridge for APC UPS models BR1500MS, BR1500MS-TW, BR1600SI and BR1500MS2
This NShi RBC163 battery cartridge replaces APC cartridge #163 in supported UPS units. It arrives fully charged and is ready for immediate installation. The unit carries a one-year replacement warranty from the supplier. It is built for owners of the listed APC models who need a direct swap.
The cartridge is confirmed compatible with APC UPS models BR1500MS, BR1500MS-TW, BR1600SI and BR1500MS2. No additional accessories or software are included in the package. The battery chemistry and connector layout match the original cartridge specification. Installation follows the standard APC replacement procedure.
Verify that your UPS unit carries one of the four model numbers above before ordering. The cartridge will not fit other APC models or third-party UPS units. Confirm the physical cartridge bay matches the RBC163 form factor. Buyers who need a different cartridge number or a higher-capacity pack cannot use this item.

The cartridge arrives fully charged and carries a one-year replacement warranty, so plan to swap it after roughly three to five years of normal UPS duty.
The connected UPS models — BR1500MS, BR1500MS2, BR1600SI — are rated for 1500 VA or 1600 VA, so battery capacity will be the limiting factor before the inverter reaches its ceiling.
The sealed lead-acid pack itself is silent and generates only modest warmth; any fan noise or extra heat comes from the UPS electronics, not the cartridge.
