21v Lithium Battery - 4.0 Ah Battery with Charger Adapter Led Indicator Compatible with Leaf Blower

Excellent product works better than expected. Quality product, fast deliver from Amazon. The price is way, cost effective from the competitors.

I received the SHINTYOOL 21v Lithium Battery with Charger Adapter (4.0 Ah), and I am genuinely impressed. I took a chance hoping this would be a compatible solution for my slightly older, off-brand 21v cordless leaf blower—and it was a perfect fit! Finding reliable battery replacements for generic or lesser-known tool brands can be a nightmare, but this SHINTYOOL battery snapped into place smoothly, instantly reviving my leaf blower. The 4.0 Ah capacity is a significant upgrade over my original battery, providing a noticeable increase in run time. I was able to clear my entire yard without needing a recharge, which was never possible before. The accompanying charger works quickly and efficiently, and the built-in LED indicator on the battery itself is incredibly useful for quickly gauging the remaining charge without having to plug it into the tool or charger. This battery delivers consistent, strong performance and proves you don't always need to buy the expensive OEM part for quality power. If you have an off-brand 21v tool, give this battery a try—it's a high-quality, high-capacity solution. Pros: Perfect fit and compatibility with generic 21v tools. 4.0 Ah capacity delivers excellent, long-lasting run time. Reliable and fast charging. Clear LED indicator for checking battery life.

Working well using it in backpack sprayer holds a change for days.

Fit my off-brand leaf blower after others would not. 1 star withheld because it's only 4Ah so won't run when fully charged as long as a 6-8Ah ones. Fairly fast delivery right to my front porch. Hopefully it will last longer than my previous one that was only providing 2-3 minutes of run time after a full charge procedure After using for less than a year. Reasonable price with a charger included.

Fit perfect and charges well… my old one got left out side ( carelessness from someone else other than me ) it got weathered and couldn’t home its charge. This was the replacement for it and I am very grateful!!

Love it.

High powered with many uses.

Ordered to have a backup battery ready when we need to use a battery operated snow shovel we recently bought. Received and immediately fully charged the battery. We took up to our cabin to run it but the snow had melted. So we just ran it without actually using it for about 15 minutes and this was good. We will update if we experience any issues. The charger worked as it should as well. So we are set for the next snow storm. Might not be until next winter-but we are prepared now. This will also work on other items like leaf blowers and small garden equipment.

Muy buen producto, incrementa las horas de trabajo del taladro sin tener que estar regresando a cargar.

Works better than the origional

Bought this as an additional battery for the IBELOMR Leaf Blower I bought a couple of years ago. It fits and works well. Does my whole yard easily on one charge so battery life looks good.

Muy bien

Please take this product back and refund it. I have never received such a dirty product from Amazon.
