Anybody out there know how ?

Experienced gardeners share their insights in answering this question :
Repairs on these are NOT really pratical and usually only temporary. The problem is caused when you continue to use the battery after the drill shows signs the battery is losing power. By continuing to use the battery, the remaining cells drive current in reverse through the cells that have collapsed. These cells OFTEN then short and are impossible to recharge once that occurs. Sometimes one can blow open the shorted cell by applying a higher voltage at reasonably high current for a few seconds but this is DANGEROUS. The only othe repair is to replace the cells and this is USUALLY not an economical fix.

In the future, as soon as you sense the drill is weakening, charge the battery. Best to have at least two and cycle them.

Note the OLD saying about completely discharging NICAD’s just didn’t take into account the shorting of the weakest cell.

How to Identify and Fix Common Gardening Problems ?

We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :

All is not lost because you can revive them. If you have a balance charger designed for charging LiPo batteries, chances are it will revive your lithium-ion cells too. Or, if you have a digital multicharger that has `revive` functionality, that will work too.
Rechargeable batteries have an expected lifespan given by the manufacturer. If your drill battery is losing power and in line with the expected lifespan, it`s probably time for a new battery. There are ways to extend your battery`s charge, and there are also more specific ways to examine your battery`s effective life.
The lithium battery will lose its ability to hold a charge over time, eventually leading to the battery being rendered useless. The main reasons are the power consumption of BMS (battery management system), as well as the battery overdischarge caused by the battery self-discharge.
If a battery is completely dead but has been revived by a jump start, there are ways to fully recharge your battery. The first is, as mentioned, by driving around. If that does not seem to work, however, car battery chargers can regenerate all of the charge into a battery.
Eventually all drill batteries lose their capacity to hold a charge and deliver optimal power. But reconditioning can revive and rejuvenate batteries that you thought were dead. What you have to do depends a lot on the chemistry of the battery. Never buy another replacement battery.
In any case, you will have to plug in the battery and wait until it is 100% full. Then wait until it is almost empty, about 5%. Then, plug it in again and recharge it again. Repeat the procedure several times, until you get a reconditioned battery.
If you need several, it`s almost cheaper to buy a new drill/battery combo. It is not uncommon for only one cell is bad in the battery pack. Getting a replacement cell makes economic sense. And at about $1 per cell, even replacing all of the cells in the pack is way cheaper than the alternatives.
Power tool batteries will die quickly if they`ve been stored improperly, if they are too old, and if they are low-quality. The battery may also be too small for the job. Also, if the battery has been damaged or improperly charged, you could see reduced charge times.
This can be caused by overcharging, undercharging, or leaving the battery in a discharged state for too long. A battery that doesn`t hold a charge is frustrating and can happen for many reasons. It could be an issue with the batteries themselves or a problem with the charging system.
Corroded Battery Connections

Electrolytes from the battery top can cause corrosion of the connections to the battery cables and prevent them from reaching a full charge, so the battery won`t hold a charge for long while driving along.

How long does a drill battery take to charge? For brand new batteries, charging it overnight will ensure you have a full charge on each individual cell. From that point on, future charges can take between three to six hours to achieve a full charge.

Battery?, wiring?? Had a recent problem with blades not engaging. I have had also had a slightly older issue of battery not holding charge so i have to boost or jump start mower. I went out and bought brand new battery and after one usage it would not hold charge and blades will still not engage. Would the issue related to the battery effect the engagement of the blades???
ANSWER : If your Alternator didn’t charging the battery, even though you brand new battery will not last. So there is two possible cause, 1) Your Alternator is not functioning. 2) there is a wiring problem that causing your battery to discharge easily, but you check it after you switch off the key remove the battery negative terminal then touch it back to batt term. and see if there is little blue spark, if does your wiring system got problem. If not, so your Alternator do not charge the battery.
