APC Smart-UPS 5000VA Replacement Batteries

Replacement batteries for the APC Smart-UPS 5000VA family

This collection covers compatible replacement battery kits for the APC Smart-UPS 5000VA line, including rackmount, tower, and Dell-branded (DL-series) variants. When the runtime on your 5000VA unit drops or the front panel flags a battery fault, a new battery kit restores backup runtime without replacing the UPS itself.

Battery type and how the pack is built

These units use sealed lead-acid (VRLA / AGM) cells wired in series to build the high DC bus voltage a 5000VA online or line-interactive UPS needs. The string is assembled from multiple 12V blocks, and larger or extended-runtime configurations add further strings to increase capacity. Because the cells are wired in series, every block in a string must be replaced together, as a matched set, so the pack ages and charges evenly.

The exact system voltage, amp-hour rating, and block count vary by model within the 5000VA family. Do not assume a single spec applies to every unit. Confirm the voltage and amp-hour values shown on the individual product page, and check the label on your existing battery pack, before ordering.

Identify your battery by exact model

The Smart-UPS 5000VA family includes many close variants that are not interchangeable. Find the model number on the label on the back or bottom of your UPS, then match it exactly to a product title in the grid on this page. Each product lists the kit for that specific model along with its published specs; order from the page whose model number matches yours rather than relying on a family-wide spec.

OEM versus aftermarket

You have two paths when replacing batteries. APC replacement battery cartridges (RBC kits) carry the manufacturer label and warranty; APC lists 2 × RBC55 for the SUA5000RMI5U and SUA5000RMT5U, and APCRBC140 for the SURTD5000 models. The kits in this collection are compatible replacements matched on voltage, capacity, terminals and connectors.

How long batteries last

Sealed lead-acid UPS batteries typically last three to five years in service. Heat is the single biggest factor: as a rule of thumb, battery life is roughly halved for every 8°C of sustained operating temperature above 25°C. Keep the UPS in a cool, ventilated space and run a self-test periodically so the unit can flag a weak battery before an outage does.

Replacement steps

1. Confirm your exact UPS model and order the matching kit.
2. Note your unit's form factor. Rackmount and tower Smart-UPS models in this 5000VA class are designed with hot-swappable battery modules, meaning the battery can be changed while the UPS continues to power the load. Always verify the procedure against your specific model's manual before starting.
3. Open the battery compartment, disconnect the old pack, and slide it out.
4. Insert the new kit, reconnect the leads, and secure the cover.
5. Reset the UPS battery-replacement date and run a self-test to confirm the new pack is recognized.

FAQ

How do I know which kit fits my UPS? Match the model number on your UPS label to the product title exactly. The 5000VA family has many similar part numbers that are not interchangeable.

Can I replace the battery without shutting down? The rack and tower Smart-UPS 5000VA units in this collection use hot-swappable battery modules, so the load stays powered during the swap. Confirm the steps against your model's manual before beginning.

How often should I replace the battery? Plan on every three to five years, sooner if the UPS runs warm or flags a battery fault during self-test.

Are compatible kits safe to use? Yes, when they are correctly matched to your model's voltage, capacity and connectors.

Do you ship to Canada? Yes. Kits ship from Canada, with no cross-border duties.
