To find the right battery, look at the old one. There will be a number of volts and a number of amp hours (AH) written on the battery. Sometimes the information is "encrypted" into the part number. Examples are UB12100 (12V 10AH),  BP12-12 (12V 12AH), DW1212 (12V 12AH), etc. You can verify your choice by checking the dimensions. If you order the wrong batteries, we will exchange them, but you are responsible for shipping.

D&D brand batteries (yellow background) are manufactured for ElectricRider to power our Phoenix, RoadRunner and Sparrow systems. They are built to deliver high current and long life - to the same specifications as their their B&B counterparts - but at a lower price. We offer Pre-Made packs for Phoenix, RoadRunner and Sparrow from our Parts page. Look alphabetically under part number beginning with X-SLAPack to find the one you need.

Vego SX600 and Vego IQ450 Batteries

As of March 2008, we do not have enough orders to have these batteries manufactured. The manufacturer requires a minimum, most of which would be discarded at the end of their shelf life.

Below are some alternative ways to power your Vego scooter. They do not restore its original capacity, but they bring it to 90% of its original range (distance per charge). Please be careful with batteries and associated wiring. You won't get shocked, but each battery has enough power to melt copper, aluminum, thin steel, etc. 

For SX600, you can squeeze four 12V 10AH batteries into the space. We've tried it.. it works, but you have to turn the scooter upside down to coax the batteries out. It is a tight fit. If your connectors are bad, replace them with something standard like Anderson 50A connectors (you need two to make a connection -- one on the scooter, one on the battery pack). 

For IQ450, you can get 10AH batteries into the space, but you have to use foam or some other material to hold the front battery in place to keep it from damaging the circuit breaker.

Be sure to observe the polarity of the old batteries and connect the new ones the same way. You'll find that battery 1 negative connects to the scooter, battery 1 positive connects to battery 2 negative, and battery 2 positive connects to the scooter.

These are the best solutions we have to offer. Since Vego has been out of business for so long, it is not likely the situation will improve. The only scooter we know of that is comparable in reliability and quality is the GoPed ESR750.

Warranty Information: B&B Batteries are guaranteed free from manufacturing defects for a period of one year from purchase. Repeated deep discharge of any lead acid battery will cause it to fail prematurely. This is not a manufacturing defect and will not be covered under warranty.

Making your batteries last

A sealed lead acid battery will survive about 300 discharge/recharge cycles under ideal conditions. Electric Vehicle (EV) use does not present ideal conditions. EVs can draw a tremendous amount of current, and many scooters and bikes will allow the batteries to be deeply discharged.

To get the maximum life from your battery:

• Do not discharge beyond 80% of capacity, generally around 10.5 volts. Better products have electronic controllers that prevent deep discharge. Low-end products can allow batteries to be drained completely, a condition from which they will never fully recover.

• Recharge immediately after each use. Do not allow them to sit in a discharged state.

• Recharge overnight every couple of months when not in use, or use a charger (such as Soneil) that is safe to leave on all the time. It is best if you can run the batteries down a bit before the charge. This will push the charger into a higher initial charge rate, which is good for the batteries.

• Dead batteries WILL freeze. Charged batteries will not.

• Use a charger rated at 1/2 or less the AH capacity of the battery pack. If you use a 6A charger on a 12AH battery pack, expect the life to shorten somewhat. This is the trade-off for quick-charging.

• If you use a fast charger that does not use multi-stage charging, do not leave the battery on the charger after the charge is completed. Low-end chargers left connected will ultimately destroy the batteries since they deliver more current than the batteries can handle once they are fully charged.

• If you choose to be "extreme", for the first 10 recharges, run the battery pack down about 25%, then recharge. This will condition the battery, setting it up for a longer life.

Battery Life Expectancy
Following is a post from a discussion group. The author did a good job explaining, and so many people ask about this, I copied it directly to this page for your convenience. We do not know the author, he/she has nothing to do with ElectricRider, and we have not done independent research to verify the information, but it is consistent with our experience.

Posted: Tue Dec 12, 2006 2:38 am    Post subject: Sealed Lead Acid Battery Information I gathered the informtion below from alot of different places on the internet and have put them together in a way I hope will be informative for the user at large. It should be noted that the cycle lifes stated are for general purpose batteries which are the ones commonly used because of low cost. Some batteries like the B&B Batteries EB Series of batteries are made for high cycle life with deep discharge and will provide more cycles then standard batteries when used for electric transportation needs. The voltages listed below are still valid for all SLA batteries. This Information is for Sealed Lead Acid (SLA) Batteries Only: 12 Volt batteries have 6 cells each 24 Volts = 12 cells 36 Volts = 18 cells 48 Volts = 24 cells Fully charged cell voltage = 2.1 Volts Nominal cell voltage = 2.0 Volts The recommended end-of-discharge voltage for sealed lead-acid is 1.75 Volts per cell. The discharge does not follow the preferred flat curve of nickel and lithium-based chemistries. Instead, Lead-acid has a gradual voltage drop with a rapid drop towards the end of discharge. The sealed lead-acid battery should not be discharged beyond 1.75 Volts per cell, nor should it be stored in a discharged state. The cells of a discharged lead-acid sulfate, a condition that renders the battery useless if left in that state for a few days. Always keep the open terminal voltage at 2.10 Volts and higher. The cycle life of sealed lead-acid is directly related to the depth of discharge. The typical number of discharge/charge cycles at 25°C (77°F) with respect to the depth of discharge is: * 50 - 100 cycles with 100% depth of discharge (full discharge) * 150 - 250 cycles with 70% depth of discharge (deep discharge) * 300 - 500 cycles with 50% depth of discharge (partial discharge) * 800 and more cycles with 30% depth of discharge (shallow discharge) Cycle life measured until 80% of original capacity can no longer be recovered by charging.
