Can you use a 7.5 volt charger for a 6 volt battery?

No. The supply would not be able to provide enough current and would likely overheat.

Can you charge a 4ah battery on an 2ah charger?

Can i use the parkside plg 20 a1 charger to charge a 20v 4ah parkside battery, the original battery was a 2ah. Answer: Hi. Yes you can.

Can a 5v charger charge a 6V battery?

To charge a 6 V lead acid battery requires 6.9 to 7.1 V. 5 V will just not work.

Can I use a 6 volt charger on a 12 volt battery?

No, there is not enough voltage provided by 6 volt charger to be able to charge a 12 volt battery. No, there is not enough voltage provided by 6 volt charger to be able to charge a 12 volt battery.

Can I use 4Ah battery instead of 2.5 Ah?

As already stated above, yes you can use a 4Ah battery instead of a 2Ah one. But you must make sure the replacement battery is of the same voltage if you intend to do this.

Are trickle chargers bad for batteries?

Leaving an unattended trickle charger on for too long might lead to overheating, causing the battery to boil the electrolyte. The outcome would be a dead battery or a worse case scenario— a possible fire/explosion.

What is the best voltage to charge a 2nd Battery?

Second yours is a gel or AGM lead acid battery, charge must be limited when voltage reaches 14.3 – 14.5 volts to avoid gassification of the electrolyte, this is usually done by electronic circuitry in modern chargers. So, a 3 amp, 12 volts charger that is specifically designed for battery charging will do the job the fastest and safely.

How many amps do you charge a 7AH battery?

A 7AH battery is charged at various rates by different chargers; standard slow charge is C/10 or 7ah/10 or 0.7 amps. Lead acid battery don’t like to be charged too fast as they heat up but you can do it maybe 1 amp or 2 amps.

What size Charger do I need to charge a 12V battery?

So, a 3 amp, 12 volts charger that is specifically designed for battery charging will do the job the fastest and safely. What is the charging input of a 12V 7Ah battery?

What voltage to fully charge a Leand acide battery?

Assuming a high enough voltage isn’t available, you can use an electronic constant current source to do the same thing – I would suggest 12V or so for charging 7.2V from a constant current source. Not open for further replies. what voltage to fully charge a leand acide battery?
