I was not sure about the length of time this battery was to last for my weed wacking; and it is now very good.
Had what I needed and the price was good.
I've only had the battery for a few weeks and so far it works every time. Which gives me confidence that I can get the job done.
Gives me 45- 60 minutes good cut time before putting on charger. Gives me freedom to swap out out to other to my other batteries to finish job
great price
Charger completely shuts off when done. I use it to power the var speed leaf blower BL4714. Well balanced machine, easy to hold for a long time. I get 25 minutes at med speed which is great to clean my deck and walkways of light debris.. Not loud. Very happy with the purchase, Cost a lot customs and shipping to Mexico but glad to grab and get 'er done.
I really like these 4 hour batteries They charge pretty fast. The only thing is they are a little on the heavier side but that's not a bad thing. It just depends on the tool you are using and what you are doing. I like using it on the drill and impact because it seams to balance the tool better, but after a long day and your arms are tiered you switch to the 2 hour. But for a long lasting battery the 4 hour is great. I think I heard that there is now a 5 hour battery but I'm not sure, im going to have to look for one.
Used it on a Skil router, minimum use, but it stopped charging entirely after a half dozen cycles. My 5Ah is doing great, as are my 2Ah. This one just fails the mark :(
Leaking after a few weeks usage. Will not take a full charge. I've had problems with 3 of these batteries. Will be purchasing different brand of tools. Skils no good!!
I would have given this battery a rating of "0" if it was possible. Bought It in December, charged it fully and stored it in a case with the Skil Reciprocating saw. Went to use it 3 months later and it had leaked some kind of oil. What a mess. Stay away from this battery.
