Reading the answers below, I wonder if they changed the battery at some point along the way or if we're just confusing model numbers?Mine came with two standard/slim batteries which are marked 1.3ah, 23.4wh. My batteries are model number BAT609But on a practical answer, rest assure that the battery is more than adequate. I'm not sure exactly how this stacks up with the other brands, but it lasts plenty long and with the quick charger you can just keep swapping batteries all day.

I just took the battery out and it says 1.3Ah and 23.4 Wh on the side. Assuming that is 1.3 Amp Hours and 23.4 Watt Hours. The battery lasts for a couple hours of pretty steady usage so seems about right. I bought two batteries, I charge one while I use the other... just swap them out and never run out of juice. Great drill by the way. I also bought the skill saw that takes the same battery. Both are great tools.

This Bosch drill / driver has 1.5 Amp hours. I am using mine for home use, but have gone 4 or 5 days of serious use and have still not had to recharge the battery. As listed, this drill also comes with 2 rechargeable batteries. I hope this answer is adequate. If not, please clarify.

You are paying for quality, but the price is afordable.I used Dewalt, Ridgid, Milwaukee and even Ryobi. The quality of Busch is better than any of those. Batteries (SLIM PACK) are 1.5 ah and 27 wh, but they last as long as 2 ah

In this instance, "bare tool" means no battery, no charger, no case, no accessories. If you already have the right Bosch batteries and charger, buying this bare tool makes sense. Otherwise, buying the kit makes more sense and is often the cheapest way to get what you need. I will say it is the best cordless drill I have owned. I have had Makita and DeWalt in the past and they just don't measure up to the Bosch.

this battery is not rated in amp hours. It has a 200 amp reserve capacity and according to information gleaned from some forums Generally the Ah is 1/2 the RC. I routinely run this battery all day(8-10 hours) to a DC to AC inverter that powers a dewalt 18 volt battery charger, an apple airport, a brother printer and sometimes another dewalt charger. One night I left the first three items on without plugging in my recharger for the Roadforce and it was depleted the next morning--probably 12-14 hours. Hope this helps

A prior review states ... " Unfortunately, the unit is sold with a cheap 12 Volt, 7.0 Amp-Hour internal battery that cannot hold up under the rigors and demands put on it by the general consumer. Anyway, the battery in any of these types of portable devices doesn't last forever and will eventually have to be replaced. Think of is as normal maintenance, to be done every two to five years, even with the best of batteries. But a simple change to a 12 Volt, 8.5 Amp-Hour, high-rate replacement battery will greatly enhance its performance. Without going into a stuffy brain-dump: A simple 21% increase in Amp-Hour capacity (to 8.5 Amp-Hours) will double the amount of work the fully charged battery can do, under load, such as the internal 12 Volt compressor motor. The "high-rate" designation is also a type of battery that is designed to take heavy loads without damage -or shortened battery lifespan." I have not actually replaced the battery, but it has every appearance to be replaceable

The battery reads 2.0 ampere-hour. It runs on 20 Volts. As for standard amps, that's a good question. The battery pack reads: DCB203 Battery Pack Type 2. 20V (max) 2.0Ah 40Wh. If it helps, I will say - the battery runs forever (as a home owner; not a construction worker). Also, I have a lot of tools and this has become my favorite! Hope that helps.

I talked to my husband about this battery . he really like it and very little to useful with this kind of drill battery to keep charge or recharge. Speaking of warranty is really good lifetime.

Amp hours are a measure of power. Theoretically, the battery should provide 125 amps for one hour at the stated 12 volts. However, at this high a current, I wouldn't count on it. More realistically, the battery should provide 10 amps at 12 volts for 12.5 hours or 20 amps for 6.25 hours...and so on and so forth. My experience is limited because I use them (two of them) along with an inverter to run a refrigerator and a few other pieces of equipment in a back up mode. They have done great when I've needed them!

Hi,The manual says that the tool weight is 1.0lb(0.45kg).Nothing is mentioned about with or without battery. Too me the battery is very light, not an issueAll the guys that work in the shop use cordless drills or pistol type cordless screwdriver. This Hitachi is a hell of bit lighter. I never feel fatigued using it and I use it for long hours. I can't weigh it since it's at work to confirm. When I get back, I'll try to weigh itHope this helps,Take care,Frank

If the mounting and contacts are the same then yes the 1.5 ah is the average time the has enough power to run the drill. So the 3ah would last longer. WARNING Makita batteries have chip on board. Those chips often turn the battery off with no way to fix it. Plus my experience has been ,that they won't do anything to about it. Amazon was awesome in taking care me when the battery I had just gotten failed.. try it!!

i am not a technical expert and so what i say is not to be construed at professional advice. i have used this battery for two separate cordless phones which appeared to have a very similar power specification and had a battery pack of 3 sealed batteries about the size of AAA. the cordless phones i used were from AT&T; and part of a set of 3. i could not find the battery in several stored i checked. so.... thanks amazon......i hope that helps.

I have a powerful drill motor, jigsaw, and the vacuum. I have never had a problem with the batteries, whether running them down all the way or charging them when they began to get weak. They are 3ah batteries. I rarely use my tools long enough to run a fully charged battery completely down. I have, at times, run down a fully charged battery, however, without the negative result you are reporting. I can count on all five of my batteries. I keep the ones not connected to my tools fully charged and ready to use.

The Genesis GCD18BK cordless drill, is not awkward or clumsy by any standard, but a fully charge battery only last about 30mins if used continuously. It does not have any tangible torque. It is easy to use though.

It was confusing to me too, but somehow I figured it out. Maybe I asked DeWalt for help. I bought two of the DC9180 lithium-ion batteries. Lithium-ion seemed like the better choice for use in my DeWalt drill, my DeWalt vacuum (DC515), and my DeWalt battery charger (DC9320). Amazingly, the instruction manual for the drill does not say anything about the proper battery. But it does mention batteries in the section about product warranty. It says that there is two years's worth of free service on these battery packs: DC9071, DC9091, DC9096, DC9180, DC9280, and DC9360. On the drill itself there is no mention of batteries.

These are two common ways battery capacity is measured. Wh stands for "Watt hours", and it's a measure of the actual energy content of the battery; it measures how much power (watts) the battery can supply multiplied by the number of hours it can do so before it runs out. Most batteries are labeled with a capacity in mAh (milliampere hours). This is a measure of the electric current the battery can supply multiplied by the number of hours it can do so. Example: if a battery is labeled 3000 mAh, it should be able to supply 3000 mA of current for one hour, 1500 mA of current for 2 hours, etc. So, 98wh indicates how much power the battery can supply and 6270 mah is a measure of the electric current the battery can supply. Hope that answered your question.

Per Amazon Review page: Battery life: what to expect, January 15, 2011 By James Savage This review is from: Ryobi P100 ONE+ 18V 1.5m-Ah NiCd Battery (130224028) (Misc.) I've had the 18v Ryobi stuff for 3 - 4 years. 3 batteries, flashlight, drill/driver, reciprocating saw and circle saw. Heavy use of the drill/driver, probably 15 pounds of deck screws (built 2 decks). The batteries have served well but now need replacement. The circle saw is the one exception; not a good application because the battery drain is too heavy except in very light wood. Note that the batteries should not be left in the charger indefinitely, take them out when the green light comes on or they will deteriorate.

this is a good cordless drill, battery life depends on how hard you work it !!!!!!!!!!!
