How do I charge my Motomaster battery pack 1200

These machines always suffer with neglect and failing internal batteries. Try charging it up.

Now people use capacitive smart boosters that have no batteries, just a capacitor. The voltage in the battery is stored up in the unit over the space of about 5 minutes and then boosted back to the battery when you turn the key.

It is supposed to have a Lithium battery and they aren't supposed to drain, but my guess is that the control circuit monitors the battery and depletes it very slowly. When was it last charged? I trickle charge my boat batteries for 24 hours once a month. The same should apply for the booster.

Many leads and even board sockets can be purchased at a good electronics store locally of via a company like RS Components.

no it can not

If booster is fully charged and the vehicle battery is almost discharged it is inevitable some battery charging will take place but it is likely to be a slow and incomplete process and could shorten the life of the booster which isn't built for such work.

It is also worth noting the car alternator is also not built for charging the battery and is often incapable of doing so. The purpose of the car alternator is to keep a fully charged battery fully charged and a discharged battery can even cause damage to an alternator.

Hi, You need to leave the switch on to charge any battery so leave it on. Please leave me feed back: Malcolm Campbell, Thanks.

Remove all the screws in the handle and any more that hold the front and back case halves together. Gently separate enough to expose the wires going to the battery. Disconnect the negative wire first to stop any chance of tools touching the positive connection.The battery can be lifted out and replaced.

Mark of the battery suggests that it's a 24V. You can't use 12V charger to charge it.

if there is a car fuse, under the cover, remove it.
most of the time, it is only use to activate the LOW Battery alarm.
Put the fuse back, when fully charge.
