  • How and Why to Parallel Charge Dead Motorcycle Batteries

    This post on how to parallel charge a dead motorcycle battery is a continuation of our segment on Motorcycle Battery Testing but can be applied to all types of lead acid batteries. It is a temporary yet important aspect to diagnosing a bad battery. It also helps answer the question: Can I test my motorcycle battery with just a charger & voltmeter? The short answer is YES, kind of...

    If you have a more permanent parallel setup, such as what is used by boat or RV owners, you should jump over and read our Perfectly Balanced Charging tutorial. You will discover how a simple tweak to your set up could save you untold lost dollars and time.

    But back to diagnosing a bad battery... It is absolutely amazing how many consumers and so called professionals misdiagnose a battery as "bad". A large percentage of those so called failures were batteries that were unnaturally discharged and salvageable or were tested by an inexperienced or shady professional.

  • Airsoft Battery Question: KWA G36C AEG Electric Gun Rifle Not Charging

    Airsoft Battery Charge Question

    I just answered a question about an airsoft battery at from ShadowBandit12, and thought it was worth sharing.

    Question: My KWA G36C has not been holding the battery's charge lately. It's not every time I charge. But others, the battery doesn't even make it through the first game. I have a smart charger and a 9.6 battery for it, and I use the smart charger to charge it. I don't know if this is due to bad connections when being charged, or something wrong with my gun. Also, the charger makes a weird noise that it did not before I started having this problem. When the battery doesn't charge it almost instantly starts die, but sometimes it works fine. I have even tried getting a new 9.6v battery. but it still did the same thing. Any suggestions about what's going wrong?

    My Thoughts: I would check your charger with a voltmeter and the wire connections in the gun. Your Airsoft battery is either being shorted out in the gun, or the charger is not working and is not charging to 100% or at all. Tenergy Battery Chargers work with many types of RC and Airsoft batteries and will balance the lithium cells.

  • Tenergy Battery Question

    Tenergy Battery Question 8.4v 1100 mAhI just answered a Tenergy Battery question at from ncbairsoftteam, and I thought it was worth sharing.

    Question: Is a 8.4v 1100 mAh Tenergy battery any good? I already have the 9.6v 1500 mAh, this would just be a back up.

    My Thoughts: The batteries made by Tenergy are great batteries. In your case you will notice the rate of fire compared to your 9.6V will be slower, but that is because you reduced voltage. The battery will probably seem like it is lasting about the same length of time even though it is 400mAh less capacity. This is due to the drop in voltage as well.

  • Honda Shadow Battery - Clearing the Air MBTX9U vs. MB16A vs. YTZ14S

    The Mysterious 'T' shaped Honda Shadow Battery

    T Shaped Honda Shadow Battery

    This peculiar battery was first introduced in 1983 in the HONDA VT750C Shadow Bike. It defied the traditional rectangular shape with a front profile that looked like the letter T. The original Honda Shadow Battery part number was the HYB16A-AB. It was a wet battery with a vent tube, 150 Cold Cranking Amps and capacity of 16 Ampre Hour. This Honda Shadow battery is found more readily in various VT1100 series motorcycles from 1985 through 2000. It must be noted that not all of the VT1100 bikes use this T shaped battery so it is important to check the exact model and year. It can be confusing. The advent of the sealed lead acid and advanced AGM battery has created a bit of confusion as to which battery can be used with or is required in these Honda Shadow motorcycles. Many forum posts on and other fan favorites have made reference to which battery should be used...sadly some are leading their buddies astray. We will attempt to clear the air and help you make a wise buying decision. The chart below will be our reference guide for the 4 part numbers creating the controversy.

    "T" Shaped Honda Shadow Battery Comparison Chart
    Amp Hour16.017.511.210.5


      • Universal Power Group HUB16A-AB (wet T shaped battery)
      • MotoBatt MB16A (sealed T shaped battery)
      • Universal Power group UTZ14S (sealed - top part of T battery)
      • MotoBatt MBTX9U (sealed - top part of t battery)

    The HYB16A-AB, YTZ14S, MB16A, MBTX9U Showdown

    The original Cold Cranking Amps (CCA) of the HYB16A-AB are around 150 with a capacity of 16 AH. Many people wanted a sealed AGM replacement battery, but none were made for a long time. Then the YTZ14S was created, which happened to be the same physical size as the top portion of the original Honda Shadow Battery HYB16A-AB. The YTZ14S AGM battery has more than enough CCA to do the job, but at the expense of the AH. Most users seem to be OK with this trade off as the bikes have minimal electronics and tend to be easier than others to turnover.

    The MotoBatt brand was created about 5-6 years ago. Their goal was to create a better battery and reduce the SKU count from 184 to what is now 34 by using a QuadFlex terminal design and spacer system. These advanced AGM batteries match or increase the specs for their OEM applications in all but 2 situations.

    Motobatt came out with the first sealed AGM 'T' shaped battery, the MB16A. It has 30% higher CCA and 10% more AH compared with the OEM and is the designated replacement for the HYB16A-AB. They also make the MBTX9U which can replace the YTZ14S...and thus the confusion begins.

    The MBTX9U cannot replace a HYB16A-AB application (see true story below). It is a stretch to replace the YTZ14S which is already a lower AH rating by 30%.[We must admit, we have had no negative calls from customers where their bike actually calls for the TZ14S and are using the MBTX9U, even though we sometimes shy away from that recommendation. MotoBatt makes a very good battery.] When you try using the MBTX9U in an application where the HUB16A-AB is required there just isn't enough capacity to allow for continued use. The battery will fail in 3-9 months.

    Mr. Ferguson's True Battery Story

    Sadly, one of our dear customers, Mr. Ferguson discovered this reality the hard way. He purchased a beautiful 1998 VT1100C2 Honda Shadow motorcycle and when he went to replace the battery, simply matched part numbers. Ordinarily that would be a great method to ensure you get the correct battery. However, he pulled out a version of the YTZ14S which can work in his bike as the CCA are stronger and the AH is slightly lower than spec. He correctly matched the part number to an MBTX9U, which can replace the YTZ14S, YTZ12S, YTX9-BS. But this is NOT a Honda Shadow Battery, it is way too small in CCA and AH to replace the stock 'T' shaped HYB16A-AB. It is not worth trying to save $30.

    Mr. Ferguson's VT1100C2 Shadow Mr Ferguson's Sweet VT1100!

    Now here is a testament to the ability of the Motobatt batteries. Mr. Ferguson essentially asked his little MBTX9U to work at 160% of normal. In those unintended abusive conditions that battery still lasted the better part of 4 months before crapping out. (I have pictures of Star Trek..."Scotty we need more power!" "Captain, I'm giving her all she's got! Systems are running at 60% over...can't sustain this much longer"...) I would be willing to bet that a comparable YTX9-BS battery would not be able to even come close to matching that feat!When buying your next new Honda Shadow Battery please take the time to double check the model and year against our battery finder charts as well as check the current part number being used in your bike. You never know what a previous owner may have used in a pinch.

    Buy the Correct Honda Shadow Battery

    Let me reiterate. You can use the HUB16A-AB T shaped Honda Shadow Battery in your bike with no issues. You can use the MB16A sealed AGM upgrade. You can use the YTZ14S AGM battery which is cheaper than the MB16A, but with less power. YOU SHOULD NOT USE The MBTX9U as a replacement for this application. If you are pulling out a TZ14S battery DO NOT step down even further to the MBTX9U. STEP UP to the MB16A.

  • Battery Recycling Programs

    There are many battery-recycling solutions available to the public. In everyday life, it can be easy to overlook the problem caused by not recycling batteries. For example, just imagine how many cell phones Americans will go through in the next few years. Most of the time, those used cell phones will end up in trashcans and make their way to landfills without being properly disposed. This is a problem because of the hazards that decaying batteries can pose to our environment. As a consumer, it is important to take advantage of the convenient, and often free, battery-recycling programs available.

    In 1996, a non-profit battery recycling program called, Call2Recyle was established as the only free battery-recycling program in North America and since then has recycled over 70 million pounds of batteries in an effort to remove batteries from landfills and reduce pollution caused by the improper disposal of batteries. The way it works is quite simple; collection sites associated with the Call2Recycle program collect used and spent batteries from anyone at zero cost. Any organization can sign up to be a collection site, so if you are a retailer, consider it. The places that collect spent batteries will then send the collection to recycling facilities also associated with Call2Recycle. Call2Recycle will provide the recycling sites with kits designed to make sorting the batteries easy. In addition, the spent batteries are salvaged for metals and other products that can either create new batteries or other every day products.

    Other battery recycling programs offer low cost options to recycle your spent batteries and used electronics. Another program is the Big Green Box. This is another simple option that doesn’t require you to leave the comfort of home. Simply order the kit, put your used electronics inside, and ship it back.

    Please do your part and recycle your unwanted electronics and used batteries. Even though you may not see direct results, rest assured you are contributing to a cleaner environment.
