Vertiv GXT4-5A48BATKIT Internal Replacement Battery Kit for GXT4 500–1KVA UPS
Overview
The GXT4-5A48BATKIT is Vertiv's factory-specified internal battery replacement kit for the GXT4 line-interactive UPS family in the 500VA to 1KVA range. Rated at 48V / 5Ah, this single-battery kit is the exact replacement called out in Vertiv's own compatibility table for the GXT4-700RT230E and GXT4-1000RT230E models — if either of those units is in your rack and the battery has reached end-of-life, the GXT4-5A48BATKIT is the correct part, not a workaround.
UPS batteries are consumables. Valve-regulated lead-acid cells degrade over three to five years under normal cycling, and a degraded battery won't deliver rated runtime when you actually need it — during a utility outage. Replacing with the OEM-specified kit rather than a generic equivalent preserves the charge management profile the GXT4's internal controller was designed around. Mismatched capacity or voltage can cause incorrect state-of-charge readings, premature charge cutoff, or fault alarms that take the UPS out of normal operation.
Key Features
- 48V / 5Ah configuration: Vertiv's own compatibility matrix specifies this exact voltage and capacity pairing for the GXT4-700RT230E and GXT4-1000RT230E. Installing a kit with a different Ah rating — such as the 9Ah kit used in the 1500–2000VA models — is not interchangeable and will not seat or charge correctly in the 500–1KVA chassis.
- Single-battery kit (1 pc): The GXT4-5A48BATKIT ships as one battery assembly. The 500–1KVA GXT4 chassis uses a single battery module, so one kit completes the replacement — no partial swaps or leftover hardware.
- Grey enclosure: Matches the GXT4 rack chassis color, relevant if the UPS is installed in a customer-facing or exposed rack environment where aesthetics matter.
- Model-specific fit: The GXT4 series uses different battery kits across the product line — 5A48 for 700/1KVA, 9A48 for 1500/2KVA, 9A72 for 3KVA, and dedicated 240V kits for 5KVA and above. Using the wrong kit risks both electrical incompatibility and physical fitment issues. The GXT4-5A48BATKIT is explicitly mapped only to the 700RT230E and 1000RT230E.
- Genuine Vertiv replacement: Factory-new, genuine part — not a third-party equivalent. The GXT4's battery management system monitors charge cycles and health; non-OEM cells can trigger false health alerts or suppress legitimate ones, undermining the point of a managed UPS.
Compatibility
Per Vertiv's published compatibility data, the GXT4-5A48BATKIT (often searched as GXT4 5A48BATKIT) is the correct replacement for:
- GXT4-700RT230E — 700VA rack/tower line-interactive UPS
- GXT4-1000RT230E — 1000VA rack/tower line-interactive UPS
If your unit is a GXT4-1500RT230E, GXT4-2000RT230E, or any higher-capacity model, this is not the correct kit. Cross-reference the full Vertiv battery kit compatibility table before ordering — the 1500/2KVA units require the GXT4-9A48BATKIT, and the 3KVA unit requires the GXT4-9A72BATKIT. Ordering the wrong battery kit is a common and avoidable support issue on the GXT4 line.
For environments running multiple GXT4 units across different VA ratings — common in distributed edge deployments, branch office server closets, or campus IDF rooms — maintain separate battery replacement schedules per model family and stock the correct kit per variant. Do not treat all GXT4 batteries as interchangeable.
Frequently Asked Questions
Q: Which UPS models does the GXT4-5A48BATKIT fit?
A: The GXT4-5A48BATKIT is the specified replacement for the GXT4-700RT230E and GXT4-1000RT230E only. It is not compatible with higher-capacity GXT4 models such as the 1500VA or 2000VA units, which require a different kit.
Q: How many batteries are included in the GXT4-5A48BATKIT?
A: One battery assembly is included. The GXT4-700RT230E and GXT4-1000RT230E each use a single battery module, so one kit is sufficient for a complete replacement.
Q: What are the voltage and capacity specifications of this battery kit?
A: The GXT4-5A48BATKIT is rated at 48V and 5Ah. These specifications are specific to the 700VA and 1KVA GXT4 models — other GXT4 units in the family use different voltage/capacity combinations.
Q: Can I use the GXT4-9A48BATKIT in my GXT4-700RT230E instead of the GXT4-5A48BATKIT?
A: No. Vertiv's compatibility matrix maps the 9Ah kit to the 1500VA and 2000VA models, not the 700VA or 1KVA. Mixing battery kits across chassis variants risks fitment issues, incorrect charge management, and potential fault conditions.
Q: Is the GXT4-5A48BATKIT a hot-swappable battery?
A: Hot-swap capability depends on the specific UPS chassis design, not the battery kit itself. Consult the GXT4-700RT230E or GXT4-1000RT230E installation guide for the battery replacement procedure for your unit.
When I'm speccing a battery replacement for a GXT4 deployment, the first thing I verify is the VA rating of the installed unit — the GXT4-5A48BATKIT's 48V / 5Ah spec is purpose-matched to the 700RT230E and 1000RT230E chassis, and that pairing is not arbitrary. Vertiv's charge controller is calibrated to that specific capacity; swapping in a higher-Ah kit from a larger model doesn't give you more runtime — it gives you mismanaged charge cycles and potentially a fault condition that takes the UPS offline.
Technical Highlights:
- 48V bus voltage: The 48V configuration is consistent with the GXT4's internal DC bus architecture for the 500–1KVA range. This voltage level is distinct from the 72V bus used in the 3KVA models — another reason cross-kit substitution is not viable.
- 5Ah capacity: Sized for the runtime profile of 700VA and 1KVA loads. If you need more runtime from the same chassis, that's a UPS-level decision (external battery frame), not a battery kit upgrade path.
- Single-unit kit (1 pc): One kit = one complete replacement in the 700/1KVA chassis. No guesswork about partial kits or whether you need two units — the 500–1KVA form factor takes exactly one module.
Deployment Considerations:
- Always cross-reference the unit's model label before ordering — GXT4 models look similar physically across VA ratings, and the wrong battery kit won't be caught until installation, at which point you're down until the correct part arrives.
- Battery replacement intervals on the GXT4 line are typically manufacturer-recommended at 3–5 years under normal operating conditions; calendar-schedule replacements proactively rather than waiting for a low-battery alarm, which by definition occurs at the worst possible time.
The GXT4-5A48BATKIT is the right call for any facility maintaining a fleet of GXT4-700RT230E or GXT4-1000RT230E units in branch office server closets, IDF rooms, or edge compute deployments where standardized preventive maintenance cycles are part of the operational playbook.
