Stop Feeding the Charger Drawer: A Black Friday Cordless Audit for 2026

Every shed has a drawer like it: two chargers, a battery that fits nothing, a strimmer missing its power pack and a hedge trimmer bought in a hurry. Black Friday lands on 27 November this year, and the deals will be loud. The useful question is not ‘what is cheap?’ but ‘what actually belongs in my shed?’

A cordless audit is less exciting than a sale banner, but it is the difference between buying a tool you use and buying another orphan battery. Here is how to do it without turning the job into a weekend project.

Empty the shelf before you open a browser

Start with the shed, not the deals page. Take everything cordless off the shelf and put it on a table or bench. That means drills, strimmers, hedge trimmers, blowers, small mowers, grass shears, tyre inflators and anything else with a removable pack. Gather every battery and every charger too, including the ones lurking in a toolbox or under a bag of compost.

Write down four things for each item: brand, voltage, battery model and rough age. Then check the batteries properly. Look for swelling, cracks, leaking, scorch marks or a case that no longer sits flat. If a pack is damaged, stop using it. Take it to a household waste recycling centre that accepts lithium-ion batteries — not the kerbside bin.

Test what still works. A quick run in the tool is enough for most garden kit. Separate the keepers from the maybes and the dead. Label the keepers with a marker or a strip of tape. It sounds fussy, but it stops the same ‘which battery is this?’ conversation every spring.

Count platforms, not tools

A platform is the brand and battery family a tool belongs to. Three tools from three brands usually means three chargers, three sets of spare batteries and three sets of future problems. If you have one old drill and one old strimmer on different systems, that may be fine. If you have six tools spread across four platforms, consolidation is probably worth the effort.

There is no universal rule, but a simple test helps. If more than half your cordless tools share one platform, that is probably your keeper. If most of your batteries are ageing and replacements cost nearly as much as a new kit, do not spend good money keeping a dying system alive. And if a platform has stopped making the batteries you need, treat that as a warning sign rather than a challenge.

Match the battery to the garden you have

It is easy to buy for an imaginary garden with a half-acre lawn and a hedge the length of a cricket pitch. Buy for the garden you actually maintain.

For a small UK garden, courtyard or balcony, compact 12V or lightweight 18V kit is often enough. A small strimmer, grass shears and a blower do not need a huge battery. For a typical suburban garden, an 18V or 20V-max platform is the sensible middle ground. Look for brushless motors where they are available, and choose batteries around 2.5Ah to 5Ah for general use. Bigger packs give longer runtime but add weight, which matters when you are holding a hedge trimmer above your head.

For a larger garden with long hedges, rough grass or a lot of blowing, 36V or 40V systems, or 18V tools that use two batteries, can make sense. They cost more and weigh more, so they are not automatically the better buy. A lightweight tool you use often beats a heavy one you avoid.

Also think about the tools you are likely to add later. If you want a leaf blower, hedge trimmer and strimmer on the same battery, check that the platform covers all three. A cheap starter kit is not cheap if the next tool you need is only available on a different system.

The Black Friday traps worth avoiding

The bare tool that is not really a bargain. A bare tool comes without a battery or charger. That is fine if you already have compatible packs, but check the model number carefully. ‘Body only’ deals are not savings if you then buy a battery and charger at full price.

The kit with one tiny battery. Some kits include a compact battery that is fine for a drill but disappointing in a blower. Look at the Ah rating, not just the voltage. Two sensible batteries are often more useful than one huge one.

Voltage inflation. ‘20V max’ is often the same nominal 18V system marketed at its peak. That is not a scandal, but do not assume a bigger number means a bigger jump in performance. Compare tools within the same platform and read the battery model.

Old generation stock. A deal on last-generation kit can be genuinely good, but check that batteries and chargers are still available. A bargain tool with an discontinued battery is a short-lived bargain.

Marketplace lookalikes. Third-party batteries can be tempting, but they may not fit properly, may not be covered by the tool warranty and may not have the same safety protection. If you are spending on a platform, spend on packs that belong to it.

The ‘was’ price that never was. Before Black Friday, note the normal price of the kit you actually want. A discount off an inflated figure is not a discount. Check the returns policy too, especially for online purchases.

A simple plan for 27 November

First, finish the audit and choose one keeper platform. Second, list the core jobs you do each year: trimming, blowing, mowing, cutting, drilling. Third, buy one good starter kit with two batteries and a charger rather than three odd bare tools. Fourth, add bare tools only when you know they fit your packs. Fifth, buy a spare battery only if runtime is a real problem, not because it is reduced.

When the parcel arrives, register the warranty, label the batteries and store them indoors or in a dry, frost-free place. Cold reduces runtime, and a shed that freezes is not kind to lithium-ion packs. A simple shelf with the chargers together and the batteries in a box is enough.

The one-battery shed is not about brand loyalty. It is about fewer chargers, fewer dead ends and more time actually gardening. Do the audit now, before the deals start shouting.

The final check before checkout

Ask three questions. Does this tool fit the battery platform I have chosen? Does it come with the battery and charger I actually need? And will I still be able to buy a replacement battery in a few years? If the answer to any of those is no, leave it in the basket. A good Black Friday deal is a tool you will use next spring, not another charger for the drawer.
