NO, voltage of the charger must match the battery voltage.
No.
How long does it take for an 18v battery to charge
The best charging options for a Porter Cable 18V battery charger are to use the original charger that came with the battery or to purchase a compatible charger from the same brand to ensure optimal performance and safety.
It is not recommended to use a 12 volt 1200mah charger to charge a 9.6 volt Ni-MH 3500mah battery pack as the voltage and current ratings are different. Using a charger with a higher voltage may damage the battery pack and pose a safety risk. It is important to match the charger voltage and current ratings to the specifications of the battery pack.
This kit includes an 18V 2 speed drill/driver, 18V 7-1/4" circular saw, 18V reciprocating saw, 18V cordless flashlight, 2-18V batteries,and a charger.
To calculate the current (in amperes) needed to charge a battery at 18V in 4 hours, you first need to know the total capacity of the battery in ampere-hours (Ah). If you have the capacity, you can use the formula: Current (A) = Capacity (Ah) / Time (h). For example, if the battery capacity is 18Ah, you would need 4.5A to charge it in 4 hours (18Ah / 4h = 4.5A).
Batteryship is one website where you can buy a box of Makita 18v battery's refurbished.
You should contact the manufacture, they should offer replacement batteries. I have been in the same situation, I just purchased another tool that used the same battery. This provided 2 batteries plus I have 2 charger now and not to mention the new tool. Take the old battery and charger to Harbor Freight and see if they can match it. Make sure your charger will charge it.
I would say yes. Most electrical devices can tolerate a 10% variation in the power they're receiving.
NO! They work on either 120v (corded) or battery power. Will not charge a battery. It's one of the downfalls of the radio. Better keep a back-up battery handy. A fully charged battery (18v) will only last for 3.5 to 4.5 hours depending on volume levels.
Yes
An 18 volt Makita battery is used in power tools. These batteries are mainly used as a replacement for the Makita BL1830. They can reach a full charge in only 30 minutes.
