Rated 1.0 out of 5.0 by Maddriller Do not buy this product!
I bought a Makita drill/driver package with 2 li-ion batteries. This was an EXPENSIVE drill package. The batteries are rediculously expensive, and I was told by the saleman that they were vastly "superior" to ni-cad and other batteries, both in longivity and weight. Correct on weight, but WRONG on longivity. These batteries lasted through maybe 12-15 recharging cycles and then were basically useless. I have never been more disappointed with a product. I still own a much older Ridgid 18V drill with the "big battery (ni-cad)" and it has worked great for nearly 3 years with numerous charging cycles and is still going strong, and a much cheaper unit. If I sound mad, I am!

Rated 1.0 out of 5.0 by FamilyFarmer Batteries are (intentionally) defective
If the battery sits DISCHARGED for a while, the battery will become a brick. It will never recharge again. It's a well known defective design.
The battery control board draws power only from the first cell of the 5 cells in the battery. If you leave it sitting for a while, the control board will discharge that first cell to zero, while the others remain charged. To the control board or possibly the charger, that looks like a shorted cell, which could overheat, and the control board remembers it. If you try to charge it 3 times with an apparently deep discharged cell, sudden death! The control board tells the charger that the battery is unsafe to charge, and prevents charging in the Makita charger permanently.

Rated 5.0 out of 5.0 by ChevyTech Still going strong after 4 years.
I've had 2 of the BL1815 batteries that came with a Makita tool kit for 4 years now, and they are still going strong. I use my Makita flashlight and 1/4" impact driver every day. I think the key to getting a long life out of these batteries is to follow the directions. I put them on the charger at the first sign that they are losing their charge, and immediately take them off the charger once they are fully charged. The BL1830's do seem to be a better deal though, so I will probably buy those when I do finally need new batteries for my Makita tools.

Rated 2.0 out of 5.0 by watergeek Both batteries/ same time?
I bought my combo pack with compact batteries three years ago. I loved the lightweight batteries. After a year the charger started telling me the batteries were bad. If you disconnected and reconnected them to the charger they would charge. last week on a job BOTH batteries finally gave up. Both at exactly the same time. I really don't believe in coincidence.

Seems to last just as long as the full size battery but recharges faster. The only downsize to these batteries is you can't leave them on the charger, if you do you ruin the battery... I have ruined several before I realized what was happening. Also they attach to my drill perfectly but not the skill saw or sawzall, I can't get them to go on at all.

Both batteries I purchased online showed they were bad when I put them on the charger. Took them back to store and made exchange after they were checked out and found to be defective.

Rated 5.0 out of 5.0 by NoNickname1 fast charge, lighter weight, ample charge
for the average homeowner these batteries do a real good job of stamina; switching and charging with the 15 min charge time should be able to keep up with your needs for normal homeowner use. Supplimenting with one or two LXT 3.0amp will keep you busy doing your needed work with amply charged batteries.

Rated 5.0 out of 5.0 by TechDirector Why the bad reviews?
I have had my Makita drill, circular saw and reciprocating saw for over 6 years. Not only have the tools held up well, but the batteries still charge quickly and last a very long time. I have charged these batteries dozens and dozens of times and still get great use time out of them, even on the circ and reciprocating saw.
