Can you charge batteries with different mAh?
Using batteries in mixed configurations is ALWAYS a bad idea. Even if they are the same mAH, but from different brands or different ages they should not be used together. The issue is that you want all the cells to be depleted at about the same time so you take them all out.
How long does it take to charge a 7.2 V 1800mAh NiMH battery?
In the case of the later HPI charger with its 9.5v 330mA output, ‘fully charging’ a 7.2V 3300mAh battery would take 10 hours (thus this type of charger is often referred to as an ‘overnight’ one).
How long does a 450mah battery take to charge?
The battery unit shall be capable of supplying 440mA continuous discharge current for a minimum of 54 minutes to 1.0V end voltage within 1 hour after following process. Charge with 15 mA for 16 hours after discharged with 30 mA to 1.0V.
Does mAh matter for charging?
Most batteries will feature a number on the front that tells you the number of mAh or “milliamp-hours.” Common sizes range from 2000mAh up to 10,000 or even 12,000 mAh. Bigger numbers mean more power, which means more recharges for your smartphone, or charging for bigger devices that need more power, like a tablet.
Does the mAh matter on a rechargeable battery?
The mAh capacity rating refers to the storage capacity available for a particular battery. A battery with a capacity rating of 1800 mAh could deliver a current of 1800mA for one hour. Higher mAh ratings for the same battery type will generally mean longer run times.
How long does it take to charge an 1800mAh battery?

Do you get longer run times with higher mAh batteries?
A: Yes, the mAh rating will give you longer run times between recharges. The higher rated mAh of a battery has no effect on electronic devices other than they allow longer term use. Q: Why are AA and AAA batteries rated at 1.2 volts and alkaline batteries rated at 1.5 volts?
How many charges can you get from a battery charger?
Most of the new chargersuse a small computer chip to manage the charge and you should be getting at least 500 charges from your batteries. If not, buy a new charger. Some of the no name batteries sometimes have a short life.
