ok im a carpenter and know my tools. these work fine but dont cut off when running to hot or under to much load. seems dangerous.they dont fit small spaces like my makita cooler box.and the capacity is way wrong. its more like a 6ampthey die when they get to around 40-60 percentall in all i would say they fine for the price and work well for all tools exceptplunge track saw as the batteries hit the materialradio unless you leave the back offled light unless you leave the lid open18v cooler box just does not fit

Verry good

Once you have used them a few times the battery strength goes down using a circus saw obviously it will go down from 100% to 30% then the mortar on the saw stop then you need to recharge it fully that’s on 18 mim plywood I thought being nine amp would’ve been better ?

Really good power from these but I somehow don't think these are going to be 9ah batteries. Makita don't have a 9Ah battery available. So far they are doing well and lasting for a full day or 3 in my impact driver and getting a full 5 hours constant use on the multi tool. Only time will tell how good they are but no complaints as yet.

Well made with battery test button. Main thing I’ve noticed is they don’t seem to last any longer than my other batteries so I doubt they are 9 amp hours (I use my Makita tools every day) but I’m not complaining as they still seem good value for money

Seem to last a long time and take a long time to charge up which is fair enough but the fit is very tight.

Only used twice and died, won’t charge and no point trying to get another as I’m still waiting on my last one getting replaced

Good delivery time excellent product does the job
