  • Marcello Italy

    An excellent purchase; the battery replaced the original one in a Black & Decker PP360LN cordless screwdriver. It was necessary to modify the connection on one of the two terminals. Fast and efficient delivery, with timely updates from Subtel at every stage from purchase to dispatch. UPS courier – excellent.

    I can't say whether the product (replacement battery) is OK because I haven't installed it yet. In any case, the order was executed correctly and the delivery was very fast. From there I can only recommend the company.

  • Lukas Samuel Switzerland

    I was able to fit the battery into a Wolf Finesse 50 lawn shears without any problems; everything worked perfectly. Getting the polarity right is easy, as the terminal lugs are two different sizes. The battery fits perfectly.

100% compatible replacement for Black & Decker 3.7V batteries

Specifically designed to fit your device. See the full compatibilities list.

Guaranteed 2900mAh capacity

Unlike many competitors, our cordless tool battery capacities are true, real and guaranteed. This Lithium Ion battery is 2900mAh, giving you the reliable power you need to get the job done - exactly as advertised.

High-performance 3.7V Black & Decker battery

Our long-life replacement tool battery delivers consistently high performance that matches or exceeds that of your original battery - for fewer charging breaks and less time spent waiting for your power pack to charge.

Superior quality and safety standards

Battery specialists since 2004, our CE & ROHS certified, Grade A replacement power tool batteries undergo strict, rigorous testing throughout their production to fully comply with the highest EU standards and beyond.

Repair and reuse - the sustainable way to save money

Replace the battery, not your device. It’s the smarter, cheaper, eco-friendlier choice, cutting your environmental footprint through recycling and reducing waste.  

Recommendations for the winter season

Note: When not using the battery for an extended period (ex. such as during the winter season), charge it to 100%, then disconnect it from the charger and remove it from the device and storage the battery in a room temperature, if you store the battery into the device this could cause premature degradation.  

Choose CELLONIC and never compromise on quality. Order now!
