Understanding the roots of this battery helps you appreciate its design and find compatible components today. The CLM18VRB was the standard power source for the "Performance Power" line of 18V cordless tools. This line was manufactured for the major UK home improvement retailer B&Q and was part of its own-brand "Performance Power" range. It's important to note that the "Performance Power" brand at B&Q is related to "Power Performance" tools sold by other retailers. Furthermore, you might sometimes see this battery referred to under the "MacAllister" brand name, as MacAllister was another brand in B&Q's portfolio that used similar battery technology and sometimes shared tool platforms. This means that if you own tools labeled MacAllister, there's a good chance they are compatible with the CLM18VRB battery.
Maintenance and care tips
Keep the battery terminals clean and free from debris, dust, or grease, as this can impede the power connection. Use a dry cloth for cleaning; never use chemicals, solvents, or water. If the battery gets wet, dry it thoroughly before use. pro 18v battery clm18vrb
: Ni-MH chemistry maintains performance across a wider temperature spectrum than early-generation Li-ion options.
Charging the CLM18VRB from 0% to 100% using a standard 2-amp charger took approximately 90 minutes. Fast-charging (4-amp+) cut this down to 45 minutes. Runtime on a mixed-use drill/driver scenario averaged 2.5 hours of intermittent use. Understanding the roots of this battery helps you
