This is one of the most common questions we get. In South Africa, expect 2 to 3 years. Frequent load shedding and power fluctuations force the battery to cycle constantly, which shortens its lifespan compared to countries with stable power grids in the Bryanston area.

No, unless you are a qualified electrician. A UPS can hold a lethal electrical charge even when unplugged. DIY work also risks voiding your device’s warranty and potentially your home insurance.

However, a loud or new buzzing or crackling sound can signal a failing fan, transformer, or another internal part. It should be inspected by a professional immediately. A low, consistent hum is normal.

We recommend hiring a pro with specific UPS repair experience. While most electricians can handle a battery replacement, complex repairs involving circuit boards require a specialist with experience in power electronics.

Clear signs include the "replace battery" light being on, the unit beeping continuously, or providing only a few minutes of runtime during a power cut.
