  • OK, I'm confused about the batteries.....

    I have looked at older battery posts and I have not found the information I'm looking for.

    I have 18v batteries. I acquired them mid 2004 and early 2005.
    The batteries have 3 part numbers:
    1. 130254003
    2. RG14813
    3. AC4781

    This battery is rated 18v @1.9ah Although their ad says "rated at 2ah"

    ridgid also has:

    130252001, 18v @ 1.25ah
    130254007 18v @ 2.50ah

    I only find the 130254003 18v @1.9ah model on this Ridgid website, and when I visit the Home Depot website and local stores.

    I do see the 130254007 18v @2.50ah model being auctioned off on EBAY.

    I am going to make some assumptions here.....

    1. The 130252001 18v @ 1.25ah battery is obsolete and was likely the first
    generation ni-cad.
    2. The 13254003 18v @ 1.9ah ni-cad battery is the current production run
    and also goes under the MAX/HC label [probably for "high current"]
    3. The 130254007 18v @2.50ah is the newest and next generation ni-cad.
    This battery is currently only offered with new tool sets or by those
    auctioning them off on EBAY.


    I wonder how much extra run time 600ma will really provide? This is the difference between the 2.5ah and 1.9ah battery. [for you non electronic types 600ma=0.600A] Has anyone actually measured the tool's current draw when being used?

    For example , What is the current draw when using the 1/2" 18v hammer drill, driving a 3" deck screw into a 4x4 pressure treated post with the clutch set at 18 and the speed set to "1"?
    -or-
    When driving a 3" 1/4-20 lag bolt into a say two 2x6 treated boards with the 18v impact driver?

    Battery life is dependent upon it's condition, the tool being used, and what you are doing. As I read various posts some guy cries "the battery only lasted 5 minutes!" -or- "I only drove 4 lag bolts"...but they never indicated the variables..such as type wood [hardness], quality of lag bolt, battery and tool condition, etc.

    If the battery has been on the tool for two days in the back of the truck the battery will deteriorate and you won't get a good run time. If you take the same battery and treat it nicely, by keeping it in a cool dry clean place [in the house], charged etc, you will get a longer run time.

    I know I'm ranting here..but this applies to all battery devices, from Ham Radio battery things to tools! This also applies to all the other brand tools and their ni-cad batteries.

    My final question:

    When will this ridgid website or other related sites like home depot or even Ordertree.com recognize the newer products by ridgid and offer them to their customers? Or, at least provide specification documentation?

    I think I can shed some light on some of your questions.
    The 130252001, 18v @ 1.25ah is the battery offered with the 3/8" 18V drill R84001 and has a 20 min charge cycle.

    I would say you are right about these 2 assumptions ...

    2. The 13254003 18v @ 1.9ah ni-cad battery is the current production run
    and also goes under the MAX/HC label [probably for "high current"]
    3. The 130254007 18v @2.50ah is the newest and next generation ni-cad.
    This battery is currently only offered with new tool sets or by those
    auctioning them off on EBAY.

    "I wonder how much extra run time 600ma will really provide? "
    It is actually 600mAH, 600 milliamp Hour which as you touch on is a function of current draw and time. So I would expect that using the same tool under the same conditions the 2.5 AH battery would provide 31.6% more run time over the 1.9 AH battery.

    I have a 2.5 AH battery on the way from Ebay and intend to do a somewhat controlled test as best I can with the new 2.5 VS used 1.9 AH batteries
