We've recently talked about these scoot batteries and how they only last so long before you need to replace them. The longest I've ever had a battery last on my scoot has been almost two yrs " two summers of riding" . this is the battery that is in my scoot right now . I bought the battery before the summer in 2013 and as of the end of this summer if the scoot sat for a day or two without starting I would have to jump it. After riding a couple miles the scoot would start just fine , but again after setting for a day or two it would not be strong enough to start the scoot. Since I decided to keep riding the scoot during the winter I was going to buy a new battery . before tossing it I decided to open it up and check the level of fluid in the cells. I couldn't see or hear any fluid in the cells so I decided to add some from a car battery I had laying around that still held a charge . to my surprise the scoot battery is holding a charge after adding the acid from the other battery . I tried that before with another scoot batt but without any good results. I only filled the cells up halfway and the battery will last a couple days in under 20 degree weather and still start the scoot . I'm going to fill the cells up the rest of the way and see how long this battery holds up. The problem I see happening is the charging systems on these scoots are drying up the cells on these small batteries. Not sure why ?

If you have to add to it make sure it is distilled water

Geh3333 what kills lots of bike batteries is heat , cramped into a small place with no real airflow . If a person could direct some outside air around the battery they would not loss water from evaporation , or one needs to add a battery water level check to his weekly maintenance check over, look at your scoot and see if you could get a scoop to direct air onto the battery , as I am not sure the layout on your style of bike. one other thing if you need to glue a plastic scoop to your scoot or any plastic body parts , use baking soda and crazy glue , just fit the parts , lay a line of baking soda along the two parts and use the glue to wet it , it will never break there again , great stuff these two things

I wouldn't think much heat would get to the battery where it sits but I can't say for sure . thanks I'll have to check on that . |

Heat is not really a issue with our batteries. How they sit they get cool air from the vents behind the front wheel and as you said its not that close to the motor. The prob is they are taxed pretty hard for a little battery. I keep a conditioner on mine even when it is run everyday. Still never got more than a little over 3 years out of one

Average battery life has become shorter as energy requirements have increased. Two phrases I hear most often are "my battery won't take a charge, and my battery won't hold a charge". Only 30% of batteries sold today reach the 48-month mark. In fact 80% of all battery failure is related to sulfation build-up. This build up occurs when the sulfur molecules in the electrolyte (battery acid) become so deeply discharged that they begin to coat the battery's lead plates. Before long the plates become so coated that the battery dies. The causes of sulfation are numerous. Let me list some for you. Batteries sit too long between charges. As little as 24 hours in hot weather and several days in cooler weather. Battery is stored without some type of energy input. "Deep cycling" an engine starting battery. Remember these batteries can't stand deep discharge. Undercharging of a battery to only  % of capacity will allow sulfation of the battery using the 10% of battery chemistry not reactivated by the incompleted charging cycle. Heat of 100 plus F., increases internal discharge. As temperatures increase so does internal discharge. A new fully charged battery left sitting 24 hours a day at 110 degrees F for 30 days would most likely not start an engine. Low electrolyte level - battery plates exposed to air will immediately sulfate. Incorrect charging levels and settings. Most cheap battery chargers can do more harm than good. See the section on battery charging. Cold weather is also hard on the battery. The chemistry does not make the same amount of energy as a warm battery. A deeply discharged battery can freeze solid in sub zero weather. Parasitic drain is a load put on a battery with the key off. Battery Charging - Remember you must put back the energy you use immediately. If you don't the battery sulfates and that affects performance and longevity. Battery Do's Do regular inspection and maintenance especially in hot weather. Do recharge batteries immediately after discharge. Do buy the highest RC reserve capacity or AH amp hour battery that will fit your configuration. Battery Don'ts Don't add new electrolyte (acid). Don't put off recharging batteries. Don't add tap water as it may contain minerals that will contaminate the electrolyte. Don't discharge a battery any deeper than you possibly have to. www.batterystuff.com/kb/articles/battery-articles/battery-basics.html |

When I bought my TOMOS Nitro 150 new it came with a 7BS battery, all I did was pour the electrolytes in the battery and it lasted 3 full years before I had to replace it at the beginning of winter.
Of course I ride my scoot year round so that probably made a difference. Most of the time I hear of people only getting 6 to 9 months on a battery

Is this the time to say that my battery is the original one from 2007?  I have always plugged it into the Battery Tender Jr whenever I wasn't riding the next day. So maybe that's made the difference? Or else that I just don't get to drive my scoot very much, so it's sitting there charging most of the time (when I'm not running my scoot parked, that is)? >'Kat |

Lol I've kept mine on a trickle charge also but have never had any luck . must be nice . lol |

The 9BS batteries cost $47 with tax in my area. I keep a battery for 1 year, buy a new one and give the old one to the first scooter rider I see who's going nuts trying to work the kickstart. I just don't think they have longevity.

I got a 9bs batt and I took a torch and melted the plastic where the battery sits to make it longer my scoot could only fit a 7bs and I was able to fit a 9in it you could really take the whole box out and make a big one for an even bigger battery as long as is not to big, before the 11 pole conversion I was going to run 2 batteries with an isolator and make a box under the scoot to fit everything down there but I thought it would cover the air that comes through there for the engine just something else you can think about
