  • Lithium Iron FAQ
    Shorai LFX batteries contain proprietary eXtreme-Rate Lithium Iron prismatic cells (chemistry LiFePO4). Shorai LFX batteries contain no poisonous lead, no acid, and do not create gasses during charge, as traditional Lead-Acid batteries do. Compared to lead-acid, Shorai LFX lithium are also extremely light, have much lower self-discharge, do not sulfate, and are environmentally friendly. read more
  • Why Don't You List the AH Rating on the Scorpion Stinger Batteries?
    It is not accurate to rate a lithium battery in equivalency to "Lead Acid" because there are major differences in the usable capacity of a lead acid battery depending on the composition, the application, and the thickness of the plates. Most Lithium manufacturers, that use the "Lead Acid Equivalent" rating, compare their batteries to the lead acid batteries that their lithium battery would most likely be replacing. read more
  • Will I Need to Charge My Motorcycle, ATV, or Snowmobile Battery When it Arrives?
    When you order an AGM, maintenance free battery from BatteryStuff.com, it is first filled, charged, and load tested before it is shipped out. This process allows for you to receive your battery ready to install and ride! read more
  • Why is My 12 Volt Battery Reading as 13 Volts?
    All Lead acid batteries (Gel, AGM, Flooded, Drycell, etc) are made up of a series of 2.2 volt cells that are bridged together in series to reach their final desired voltage. read more
  • Does Starting My Motorcycle in the Winter Charge the Battery?
    While starting your bike every few weeks in the winter may be good for the mechanics of it, it could end up harming your battery. ou either need to keep it on a decent maintenance charger, such as a Battery Tender, or you need to suck it up and go for a 20+ mile ride every couple weeks! read more
  • What is the difference between Yuasa and Motocross batteries?
    Not much really. Motocross is manufactured in the same factory, the same assembly process, at the same time as the Yuasa. The only difference is the label applied at the end of the manufacturing process. Motocross came about as a way for Yuasa to enter the ever growing aftermarket, without disrupting their already established brick and mortar new bike dealerships. This allows them access to a much broader market share, at a much more reasonable price point. read more
  • What Is the Best Battery Charger for my Motorcycle Battery?
    That really depends on the size and voltage of your battery. If you have a small battery, under 6 amps storage, the Battery Tender Junior may be the best choice. If you have a larger battery, and may want to use your charger for other purposes, the Noco Genius G-1100 or the Battery Minder Plus would be a good way to go. read more
  • I Need to Find a Battery that Fits the Dimensions of a Custom Motorcycle Application
    If you have a custom application, and need to find a battery that will fit specific dimensions, you can have a look through a our complete list of powersports batteries we sell, listed by dimensions, polarity and capacity. read more
  • I Need a Gel Cell Battery. Why Do You Only Sell AGM Powersports Batteries?
    Gel battery technology was developed prior to AGM (Absorbed Glass Matt) battery technology and the term “Gel” is now often used generically, albeit incorrectly, to described sealed batteries. AGM is simply superior in this application. We've heard many times "But my dealer says...". In this one instance, your dealer is mistaken. AGM's rule! read more
  • How Often Should I Charge My Motorcycle, ATV or Boat Battery?
    Any type of lead acid battery should always be left in a fully charged condition. Having done that, you should either charge your battery every 30 days or so, or consider getting a smart charger to maintain your battery all the time. read more
  • Does My Motorcycle Have a Gel Cell battery?
    Except for a few European bikes such as limited BMW and Ducati models, AGM is the standard battery type. In almost all motorcycles that have sealed batteries, that sealed battery is an AGM, not a Gel. In fact, if you were to find a correctly sized Gel battery, it is very likely that using it in your snowmobile, ATV, or motorcycle will lead to early battery failure. read more
  • Did I Receive a Bad Battery?
    When you order a PowerSports battery from BatteryStuff, you always receive a fresh, ready to install battery. When we ship our maintenance free AGM powersports batteries, they are pre-filled, charged and ready to install. These batteries are sealed and considered “dry” batteries. Because our batteries are freshly activated you may occasionally see small acid stains on the packaging. read more
  • How Does the Powersports Battery Warranty Work?
    Batteries less than 30 days old will be replaced at no charge. For batteries over 30 days, the customer must pay for the shipping of the new replacement battery (typically $11.00). We will always work with the customer to avoid shipping charges whenever possible, which may require simple testing to be conducted by the customer at their location. The following test may be required in order to proceed with any warranty claims. read more
  • Do I Need a Special Battery for My ATV with a Winch?
    The short answer is that Powersports batteries are just not designed to handle the amp draw of a winch. They are not made for deep cycling, only for starting. That being said, in the real world we have winches. Having a higher CCA is a bit helpful, but what you really want is higher storage amps, and a battery capable of deep cycle. read more
  • Can I Use a Battery Tender on my Shorai Battery?
    While your typical Battery Tender charger is compatible with these LiFeP04 batteries, Shorai says you should use a Battery Tender "only if you really need to". The reality is, Shorai's powersports batteries have a much slower self-discharge rate than lead acid batteries. After the period of inactivity, it's okay to use the Battery Tender to charge them back to full capacity. Charge until the green light indicates "full", then take it off. read more
  • What Do I Do With My Old Dead Battery?
    Battery cores are important because not only is lead expensive, but it can be recycled and used again in the manufacturing of new batteries. As a matter of fact, approximately 97%* of lead content within lead acid batteries is recycled. That's not too shabby when you consider how aluminum, newspaper, and glass get recycled ~50% of the time or less. In a nutshell, battery recycling works, and it's a good idea to keep it up. read more

Large/RV/Marine Batteries FAQ

  • Can I Use a Solar Battery Charger to Keep My RV Battery Charged?
    Yes! You first must calculate how much power you used, so you know how much you need to replace. Your heater will be rated in watts or amps. Multiply that number by the estimated number of hours the heater ran, and you will have your baseline number. Once you have that you can calculate what size panel you need. You can use our solar calculator once you have that info. read more
  • Will a Small Charger Maintain a Large Bank of Batteries?
    Quick answer: No.
    We recommend that you should size a maintenance charger to be no smaller than about 1.5% of your battery packs full rated value. If you need to replace charge that has been drained by use, we recommend you go as close to 10-20% of the full value as possible. read more
  • How Do I Keep My RV Battery Charged When in Storage?
    If your starting battery is going dead in about a month while you vehicle is in storage, it would be fair to assume you are using about 60-75 amps(typical RV sized starting battery) in that period. To break it down further, we can assume 2-3 amps per day. read more
  • When Should I Add Extra Sulfuric Acid to my Battery?
    When you see your battery acid level begin to drop, you may wonder when and if it is appropriate to add acid, or just water. We recommend that unless a battery was tipped over and all the acid spilled out, that you add only distilled water. read more
  • Can I Store My Battery on a Concrete Floor?
    This one is an often heard ‘old wives tale’. It used to be that battery cases were made of inferior material such as hard rubber, or even tar. This material would develop micro cracks over time and become porous, and left on wet ground or damp concrete would begin to self discharge. Nowadays, battery cases are made of plastic that does not leak and can be stored on nearly any surface, even left in standing water with no ill effects. read more

  • OK, So What Size Panel Do I need?
    First, the notes: We hope this solar calculator will make sizing your panels and batteries a little less painful. Keep in mind that this is only a calculator, and it will directly reflect whatever you, the user, inputs into the fields. If your base calculations are off by even a little bit, the results reflected can be skewed by quite a bit, so view this as a guide, not an absolute. read more
