Most lead acid batteries can be charged with a boost, this can be 10 AMPs, but normally have a current sense circuit so when the battery reaches it knee it goes into a trickle charge.

CVO 1800cc will not turn over


Hi, Paula I have been turning wrenches on motorcycles, mostly Harleys, for the past 50 years and in those years I have run across all kinds of battery issues. In the beginning, I too believed in the myth that keeping a battery on a trickle charger 24/7 was the best way to keep it fully charged and prolong battery life. In 1982 I was working for Harley Davidson of Washington D.C. when a customer came in for a tire change after basic chit-chat I discovered that he had been building lead-acid batteries for the Excide Battery Company for the past 17 years and the battery he had in his Bagger was 11 years old, I was shocked, to put it mildly. For the next 45 minutes while I was changing his rear tire I got re-educated on the proper maintenance and care for lead-acid batteries. The following is what I gleaned from our conversation:
1. Choose a quality battery that has the most "CCA" Cold Cranking Amps for your application.
2. Always charge the battery to 100% capacity before installing in your motorcycle. The battery may be new but may have been sitting on the shelf for months or longer and has lost 20% or 30% of its maximum capacity charge if installed under these conditions, the first time you hit the starter button the amperage draw from the starter motor will "SET" the lead-acid plates to whatever percentage of charge the battery had at that exact moment and will never charge any higher. This situation will have a negative impact battery life.
3. Service and inspect your battery as per the owners or service manual schedule and only add "Distilled" water if necessary.
4. Always check your charging system after battery service and make sure the charging voltage back to the battery is 13.8 - 14.8 volts DC. any numbers higher replace the voltage regulator any numbers lower check the alternator/generator for proper output
5. During winter storage or months of non-use, the optimum operating/storage temperature for the lead-acid battery is 25*C (77*F). Elevated temperature reduces longevity. As a guideline, every 8°C (15°F) rise in temperature cuts the battery life in half. A maintenance-free sealed battery, which would last for 10 years at 25°C (77°F), would only be good for 5 years if operated at 33°C (92°F).
6. A long period of a low amp trickle charger for 24 hours is highly preferred over a short period high amp charger.
7. For battery life longevity during a non-use period use a trickle charger of .5 to 1 amp for 24 hours once monthly then remove the charger. Batteries like to be slowly charged and slowly discharged on their own. 24/7 charging causes the battery to heat up and it's acid to evaporate.

How to extend the battery life of Razor Scooter Batteries


You can extend the life of your scooter's battery if you take proper care of it. Most people report trouble in getting more than a year or two out of their razor scooter battery set. This is actually a common problem with vehicle batteries.

  • Keep your battery charged
It is recommended to keep your battery fully charged to avoid the build-up of sulfate-ion inside it. Sulfate-ion accumulates when the battery is in a discharged state for a long time.This is the most common reason of premature depletion of lead acid batteries. This can be easily avoided if the scooter battery is kept in a constantly charged state.

  • Charge you Razor Scooter Battery during the Off-Season
Even if not used Sealed Lead Acid Batteries will self discharge over long periods. This will leave the battery in a not fully charges state which will enable the sulfate-ions to build up inside the internal plates which will slowly deplete the battery's capacity. In order to prevent that, you should charge the razor scooter battery at least once every three months when it is not in service.

  • Use a Battery Tender
Battery Tender chargers are a great way extend the life of your SLA batteries as they are designed to fully charge and maintain a battery at proper storage voltage without the damaging effects caused by trickle chargers.

How do i change my wiring for my autogo 550 to adapt it to a trickle charger. it now has 4 wires , I need 2 wires?


this scooter uses lead acid batteries

this type of battery much like a car type
uses constant voltage

like 13,8v from a car alternator

so a trickle charger is no use and wont work
as it only provides a constant current and not a constant voltage type senario for the charge up


use a car battery charger

problem solved for about a fiver....
the scooter will need eather 12v or 24volts

so you need either a car charger or a truck battery charger

at least 15 amp @ 13.8volts...

Charging battery charger


Hi, Anonymous if you do not have a trickle charger adapter already connected to the battery you can connect the charger directly to the battery or if that is a lot of trouble you can connect the positive lead to the positive post on the starter solenoid and the negative lead to a frame or engine bolt, the best way to charge a battery is slowly. I like to use this analogy, would you rather be awakened from a deep sleep with gentle nudging or a violent kick in the rear.
1. Remove battery and check for corroded or damaged terminals clean any dirt, corrosion or electrolyte that is on top of the battery as this will cause premature battery drain, inspect for cracks and swollen/expanded sides which are a sign of overheating and replacement should be seriously considered.
2. Acid plate type batteries should be checked with a hydrometer with recorded readings for each cell to be compared with after charging readings and for sulfation, the cell will appear milky, and incorrect acid level. Fill low levels with distilled water to upper level and remove acid from over filled cells with hydrometer until the level is at upper mark and dispose of acid in the sink mixed with a quart/litre of water.
3. Connect a voltmeter set on the DC scale to the battery and record the reading for comparison after charging.
4. Attach a drain hose that is not pinched, kinked, or plugged to the nipple on acid plate type batteries and let the other end hang into a plastic or styrofoam cup.
5. Connect a 1-2 amp trickle charger that has automatic charge rate reduction if possible and let charge for 24 hours.
6. After charging recheck each cell with a hydrometer a 100% fully charged cell will have a specific gravity reading of 1.270-1.280 and 1.180-1.190 has only a 25% charge battery should be load tested and considered for replacement if necessary. Reconnect your voltmeter and
any readings in the 10-volt range means you have a dead cell and the battery needs to be replaced. Readings between any 2 cells of 50 points or more indicate the battery has failed and needs to be replaced.
7. No maintenance AGM or GEL batteries need to have a voltmeter reading of 12.8-13 volts for a full 100% charge and 12.2 volts is only a 25% charge and should be load tested and replaced if necessary.

What size wire is needed from transfer switch to generator


Most battery chargers are trickle type chargers - that is, they provide a constant low current (under an amp) output at 12 - 15 volts to keep the battery charge up. This small charging current is handled easily by a #14 or #12 wire which will pass up to 2 or 16 amps consistently, respectively (the larger cables off the battery are for the starter motor).

If you're having trouble maintaining a charge on the battery, a careful check of the charging circuit is required. Look for loose or corroded connections - at the battery in particular, open or blown fuses on the input (120 volt) side of the charger and the 12 volt output side (if provided). Battery acid is conductive. This means if there is a path of battery acid from one post to the other - no matter how long or short the path - the battery will discharge through this path. Neutralize (with baking soda) and clean any battery acid from the area to be sure the battery isn't discharging faster than the trickle charger can charge it. You can check the output of the charger with a DC voltmeter. Simply press the test leads to the battery posts and some value above 11.5 volts (11 - 12.75 volts may not be uncommon). Look at the chart below to get an idea of the charge of a lead acid battery

4_9_2012_7_36_01_pm.png

With the battery disconnect from the charger (or the charger powered off), the meter should show indicate 12 volts (even if practically dead) without a load. That's why it is important to load the battery when trying to get a voltage reading from it. Many auto parts stores sell and loan battery load / meters expressly for this purpose. They look like this:


4_9_2012_7_22_05_pm.jpg

If you have a battery that won't stand up under load, you may have a a problem with acid / distilled water level or even a dead cell. You can not check these variables in a maintenance free battery however. If you have removable caps on the battery, check and top off the level with distilled water only to a "full" or "high" level mark. A hydrometer can be used to determine the charge of each cell in the battery. These can be had for under $10 in most auto parts stores, too. They look like this:

4_9_2012_7_27_43_pm.jpg
Make sure you get one to check the specific gravity of battery acid - NOT to check anti-freeze level protection - they look similar.

Good luck!

I have the SSC-1500A battery charger and the yellow light keeps flashing. The yellow light is the charging light.not sure why


This unit will assume a battery voltage less than 1.5 volts means the battery is sulfated. The flashing yellow light means it has gone into 'desulfate' pulse mode using pulses of high voltage to try and convert the lead sulfate back into sulfuric acid and lead plating. It will do this for about 8 hours on the charger I have. If the voltage has not raised to a level that can can accept a normal charge it will abort the pulse mode and stop trying to charge it. You will need to unplug and replug in the charger to try again. Always check the temperature of the battery while charging it and especially if the charger is in pulse mode. Stop charging if the battery is hot. *always wear safety gear*

Yuasa np7-12 batterty has discharged after 7 yrs. Can I recharge using a std 12 v trickle charger?


Your Yuasa battery is of the sealed lead/acid type. These batteries are meant to be trickle charged at a voltage between 13.2 volts dc to 13.8. If the battery is dead it could take up to one day to completely recharge it. However, you mention it is 7 years old. The life of these batteries is generally 4-5 years. Their rated capacity (7 amp hour when new) diminishes over time. So there is a good possibility that your battery is getting too old to keep a charge and needs to be replaced.

DSealed Lead Acid Batteries: 12v 7ah; belongs in a Liftmaster LA400 gate control box. Can these batteries be charged using a trickle charger? I'm trying to find out if it's the battery not holding a charge...


Yes you can charge the 12 volt bttery on a trickle charger. You should use a 1 amp or less charger. Check the battery every 1/2 hour or so for heat. If it get's hot you should stop charging. Power packs that have a 12 volt rating will charge your battery safer and better but will take longer (like a cell phone charger) look at the voltage ratings on the charger. You will have to adapt the plug to hook it up and test for correct pos. and negative connections. The 7amp hour batery should be fully charged by a .5 amp (500ma) charger in about 14 hours (multiply the amps times hours of charge and do not go over the 7amp hours of the battery when deciding how long to charge). After charging check voltage, it should be around 12. Let the battery set for a few hours (overnight) and check the voltage again. It should be around 12 still. A fresh charge will usually show a higher reading (called a surface charge) than a battery sitting around. 4.5 v will not operate your device, 9.5 v or higher should.
