Review: Great for our vacuum cleaner - I recently purchased the BLACK+DECKER BL4018-XJ 4.0 Ah Lithium Ion Battery for my power tools and I have been extremely impressed with its performance. This battery has a high capacity of 4.0 Ah, which means it can last for a long time and power my tools for extended periods of time without needing to be recharged. One of the main features that stood out to me was the lithium ion technology. This battery is not only lightweight, but it also has a longer lifespan compared to other batteries. I have been using it for a few months now and I have not experienced any decrease in its performance. The battery also has a quick charge time, which is very convenient when I need to get back to work quickly. It only takes about an hour to fully charge, allowing me to continue my projects without any delay. I also appreciate the LED indicator on the battery, which lets me know how much charge is left so I can plan accordingly. In terms of durability, this battery has exceeded my expectations. I have accidentally dropped it a few times and it still works perfectly fine with no dents or scratches. It also performs well in different weather conditions, which is important for outdoor projects. Another great feature of this battery is its compatibility with a wide range of BLACK+DECKER tools. I have used it with my drill, impact driver, and circular saw, and it has worked seamlessly with all of them. This makes it a versatile and cost-effective option for those who own multiple BLACK+DECKER tools. The only downside I have noticed is that the battery is slightly heavier than other lithium ion batteries I have used in the past. However, this is a minor issue and does not affect its overall performance. Overall, I highly recommend the BLACK+DECKER BL4018-XJ 4.0 Ah Lithium Ion Battery. It has exceeded my expectations in terms of performance, durability, and compatibility. Whether you are a DIY enthusiast or a professional, this battery is a great investment that will make your projects much easier and efficient. Review: Perfect - This is quite expensive, but it lasts so much longer. And it does not even heat up like those small packs when in continuous use. It has more amps so gives more umph (strength) to powertools! :) keep in mind it's bigger - heavier, and will charge for many hours to fully charge up ## Features - Provides extended run time and optimized power to complete tasks quickly - Ideal for heavy cutting and grinding or when the tool will be used for long periods between charges - No memory effect and virtually no power discharge for maximum productivity and reduced down-time - Compatible with the BLACK+DECKER 18V Cordless System products - Lightweight and compact design ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0142TNG50 | | Amperage | 4 Amps | | Antenna Location | Cordless | | Battery Capacity | 4 amp_hours | | Battery Cell Type | Lithium Ion | | Battery Weight | 400 Grams | | Battery capacity | 4 amp_hours | | Battery cell composition | Lithium Ion | | Best Sellers Rank | 58,977 in DIY & Tools ( See Top 100 in DIY & Tools ) 237 in Cordless Tool Battery Packs | | Brand | BLACK+DECKER | | Brand Name | BLACK+DECKER | | Compatible Phone Models | Not for mobiles | | Country of Origin | China | | Customer Reviews | 4.6 out of 5 stars 1,740 Reviews | | Global Trade Identification Number | 05035048560044 | | Included Components | Components included | | Item Dimensions | 12.7 x 8.7 x 7.6 centimetres | | Item Type Name | 18V 4.0Ah Lithium Ion Battery | | Item Weight | 690 g | | Manufacturer | Stanley Black and Decker | | Model Name | BL4018-XJ | | Model Number | BL4018-XJ | | Number of Batteries | 1 Lithium Ion batteries required.
