If you rely on cordless power tools for work, DIY projects, or home maintenance, you know the frustration: your favorite drill, circular saw, or angle grinder is in perfect condition, but the battery pack refuses to hold a charge.


When a replacement power tool battery costs nearly as much as a brand-new tool set, buying OEM replacements feels like a waste. Fortunately, there is a faster, more affordable, and eco-friendly alternative: Power Tool Battery Repacking.


At Batteries Unlimited, we specialize in professionally repacking cordless tool battery packs for tradespeople, DIY enthusiasts, and commercial workshops across Cape Town and nationwide.

What is Power Tool Battery Repacking?

Battery repacking is the process of safely opening your existing power tool battery casing, removing the old or degraded battery cells, and replacing them with brand-new, high-discharge lithium-ion or NiMH cells.

The original outer plastic casing, internal circuit boards, and mounting connectors are kept intact. You get the performance of a brand-new battery—or better—at a fraction of the cost.


3 Big Reasons to Repack Instead of Buying New


1. Major Cost Savings

Original Equipment Manufacturer (OEM) replacement batteries carry heavy brand markups. Repacking reuses your durable plastic casing, so you only pay for the high-quality internal cells and expert assembly.


2. Upgrade Your Tool’s Run Time

Factory batteries often use standard-capacity cells. During a repack, we can install higher amp-hour (Ah) cells into the same housing, giving your drill or grinder significantly longer run time between charges than when it was brand new.


3. Support Sustainability & Reduce E-Waste

Power tool battery housings are heavy-duty plastic that takes centuries to decompose. Reusing your existing battery case keeps unnecessary plastic out of landfills while ensuring your old internal cells are safely recycled.
