Depends.
Batteries have two main features, their voltage and their capacity.
Both your batteries have the same voltage, 7.4 V, and that's a good start.
But they have different capacities.
If they were fuel tanks, they'd hold different amounts of fuel when filled.
The 2000 mAh (Milli Amp hours) is obviously bigger.
If the batteries are reasonably similar in their internal construction, whatever you're planning to run from the battery will probably do just fine with a bigger battery.
Just like a car or outboard engine won't mind being hooked up to a bigger tank.
There are two things that MIGHT happen though.
Batteries can also have different output currents.
Some, like a car battery, are good at delivering huge amounts of current for a short time.
They have to be, because it's what's needed to turn the starter motor.
Other batteries are better at delivering a small current over a longer time.
Back-up batteries for fire alarm systems and things like that do better with that kind of battery.
So if the 1200 battery is meant for a high-and-short discharge, replacing it with a low-and-long discharge unit probably won't work very well. That can cause damage to the battery.
The other way around - using a high-and-short discharge battery for a low-and-long discharge set-up doesn't damage anything, but the battery won't last as long between charges.
The other thing that can happen is that your charger might get upset.
Generally, the charge current a battery will (try to) pull from the charger is fairly dependent on the capacity of the battery. Bigger battery = bigger charge current.
If your charger is closely built only to deal with a 1200 mAh battery, it might not be entirely happy trying to charge a 2000 mAh battery. That's 2/3 bigger.
What else can I help you with?
Can the wrong size car battery damage the alternator?
No, not unless you installed a 6 volt battery instead of a 12 volt battery.
Does a 2000 Plymouth Neon take a 6 or 12 volt battery?
A Plmouth Neon uses a 12 volt battery.
Whats the difference of using 4.5 volt battery instead of 9 volt battery in electronic devices?
the device may not work
Is it safe to substitute a 6 volt 2000 mA adapter for a 9 volt 1200 mA adapter?
No, if you use a 6 volts adapter instead of a 9 volts adapter, you will be supplying 3 volts too little to the item that requires 9 volts. Either it may not work properly or it won't work at all. The fact that the 6 volt adapter can supply more current (2000 mA instead of only 1200 mA) won't help solve the problem of having insufficient voltage.
Can I use a 18 volt battery instead of 24 volt battery?
Using an 18-volt battery instead of a 24-volt battery is generally not advisable, as it may lead to inadequate power supply for the device designed for 24 volts. This can result in poor performance, malfunction, or potential damage to the equipment. Always check the manufacturer's specifications to ensure compatibility and safe operation.
How long do you charge a 9.6 volt 2000 mAh battery?
With a charger specifically designed to charge this battery.
What battery type is for a 2000 Saturn LS2?
The battery type foe a 2000 Saturn LS2 is a 12 volt side post. The group size of the battery is 75.
My Air soft rifle uses a 9.6 Volt 1100 mah battery can you use a 9.6Volt 2000 mah battery for a spare?
No
Can you jump a 6 volt battery with a 12 volt battery?
No
What is a 6 volt dry cell battery?
if it is any think over 1 volt it is not a cell battery it is just a 6 volt battery if you had a 1 volt then it would be a cell battery
Does using a 9.6 or 8.4 Mah volt battery instead of my 7.2 volt battery increase my dpms A17s rof?
yes it does. i used a 8.4 in the same gun and it works but don't use a 9.6 or your screwed.
If a battery has 100 amp hours at 12 volts dc how many amp hours will it have with a 120 volt ac inverter connected?
The amp hours capacity of a battery remains the same whether it is connected to a 12-volt DC load or a 120-volt AC inverter. So, the battery would still have 100 amp hours regardless of the inverter voltage.
