UPS repair

needs

Frequent load shedding and power fluctuations force the battery to cycle constantly, which shortens its lifespan compared to countries with stable power grids. In South Africa, expect 2 to 3 years.

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

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

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

The short answer is straightforward. For homeowners in Fourways, 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.
