Ndrive g800r battery charging

If the recharageable battery is more than 3 - 4 years old then the battery could be worn out.Rechargeable batteries have a finite number of charge and discharge cycles andwill lose their charge capacity over time, i.e. won't charge to 100% and graduallythe charge reduces until the battery won't charge up at all. OR The batteryshows a 100% charge but when the adapter is disconnected the battery drops offto zero capacity in a very short time. If the battery drops to an unacceptablecharge level then the battery needs to be replaced.

A new battery should have approx 12.62 fully charged
It could be slightly more
If you ever see 13 volts, on an old battery, it is gone

You need a min of 12.5, to do any testing of your vehicle, or you charge it
It should hold 12.5 or more for 3 or 4 weeks,then charge, if you let the truck sit
unused.

1) faulty battery - you'd need to get a replacement from the manufacturer (should be free if still under warranty)
2) when you initially charged the battery after purchasing, if you used it at all before it was completely charged it won't hold a charge.
3) if you live or travel in mountain area, phones lose battery power quicker due to an increase in elevation and distance from nearest tower.
4) if phone has been exposed to moisture or direct sunlight for an extended amount of time, it can damage the phone's ability to hold a charge.

honestly, your best bet is to replace the battery & allow it to charge for 24 hours in "off mode". if the problem persists, then send it in to be repaired.

I found this battery and it works with my Ultimate Wall-e, even charged with the charger that came with Wall-e:

A few solutions for you:

1) The batteries that you are using may have reached their end of life.

2) You are using higher capacity batteries in a charger that was designed for lower capacity batteries. The charger may be a 1 hour charger that was designed for say, 1500 mAH. If your batteries are 2000 mAH, then after the same hour, the batteries may not have a full charge, and will be damaged if this were the case, and the practice continues.

3) You are using a combination of batteries and charger that isn't compatible. For example, NiCD chargers cannot charge (usually) NiMH batteries, and vice versa.

4) There is always some drain by the batteries themselves, just being rechargeables. Though, this is usually on the order of 5-10% per month, and probably is not the issue.

I would put my money on saying that the batteries are worn out. Try a new a new charger / battery combination. If that works, then either the old batteries or old charger are defective.

buy a new battery brother

if its 4/5 years old

sometimes less charging the battery damages its potential and u need new battery.
do charge battery daily even when not in use.

well 2 years is a long time, considering that battery has 500-600 charges lifetime I think you'll need new battery...

Possible that whoever replaced your battery sent you the defective one back. Note the serial and model numbers on the battery, then request another one. When you receive the replacement, do a full recharge. Most new batteries come already half charged. Even in this state, take time to fully charge it (between 4 and 8 hours depending on the type and model). Then try running it on battery power. If the charge holds more than 2 hours on a new battery, youre good; less than an hour new, its defective. If after all of this still not resolved, request the company honor their warranty (usually a limited one year with purchase).
