Review: Good replacement for older Kobalt lawn mower - Bought as an extra battery for older Kobalt mower since the original one that came with mower is aging out and runs out of power too soon. The newer version fits, works well in the mower, can be recharged in my original charger, and holds the charge long enough to finish cutting the front lawn as did the original one when new. So far, very pleased with my purchase. Review: Standard battery of today that works pretty well - The battery is what one would expect today. They are too expensive, heavy, and only last about 25 minutes. Then it takes 2-1/2 hours to recharge it. If you have a decent sized yard with trees, you'll need two of them and maybe two chargers. Alternatively, you wait to finish the job. Kobalt is average when compared to others. It seems that my description above is true for all of them. ## Features - validated_bullets1 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B083W6M5MS | | Amperage | 4 A | | Best Sellers Rank | #29,664 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #247 in Cordless Tool Battery Packs | | Brand | Kobalt | | Color | Blue | | Compatible Devices | Solar | | Connector Type Used on Cable | Kobalt proprietary connector | | Current Rating | 4 A | | Customer Reviews | 4.5 out of 5 stars 1,383 Reviews | | Input Voltage | 240 volts | | Item Weight | 1.15 kg | | Manufacturer | Kobalts | | Mfr Part Number | Ab-135 | | Number of Items | 1 | | Number of Packs | 1 | | Output Voltage | 40 volts | | Specification Met | FCC, UL | | UPC | 370801870165 | | Unit Count | 1 Count | | Warranty Description | 3 year limited warranty | ## Product Details - **Brand:** Kobalts - **Color:** Blue - **Item Weight:** 1.15 kg - **Output Voltage:** 40 volts - **Specification Met:** FCC, UL ## Images ![40-Volt 4-Amps 4.0ah Rechargeable Lithium Ion (Li-Ion) Cordless Power Equipment Battery for Kobalt - Image 1](https://m.media-amazon.com/images/I/617Tl8hGCfL.jpg) ## Questions & Answers **Q: Will this fit inside the Kobalt 12 inch snowblower shovel that has a 40 volt 2.5 ah battery or is this one larger?** A: Being in South Texas, I can't answer about snowblowers specifically but the 4amp replacement battery is interchangeable with all of my lawn equipment.
