First, the battery is a Lenmar PBA50 found on ebay.
Second, place the amplifer onyour lap with the battery cover off and tap it on your leg, the battery should slide out the back.
Third. I have 2 of these amplifiers and both would not charge or play on battery. The problem is the metal spring contacts the make contact on the battery, they get out of shape and fail. I bent them around until I was able to make the work, but do not like that solution. Beside the left in of the battery is a small "pocket" if you will. I opened up the amplifier (BECAREFUL the handle come loose and there are nylon washers on each side total of 4 that will do what ever they can to escape.) With the amp opened I located the 2 wires going to the metal battery contacts and cut them off and removed the contacts. I then drilled a hole into the small "pocket" and routed the wires down thru the hole. I remove the battery and carefully soldered a wire on each battery contact. I then put a et of connectors on the wire end making sure I kept the polarities correct and plugged the into each other. I now have very good battry connection and all works well.

Should I Remove the Laptop Battery?


Question: Should I Remove the Laptop Battery?

I have a dell latitude d820 laptop at home which I use as a desktop replacement. As such, 99% of the time the laptop is being used it is plugged in. I wonder if I should remove the dell latitude d820 battery so that it is not permanently being charged, or does the laptop cut off the current to the battery once it is fully charged? I do unplug the laptop when I turn it off.

Answer: When using a laptop as a desktop replacement the battery should not be left in for long periods of time. The laptop will over time discharge the battery. Remove the battery – making sure that it is charged to 40% and store it in a dry, warm place. Ensure that it is wrapped protectively and nothing will be dropped on it.

The battery should be re-installed every 3-4 weeks and allowed to fully discharge. Leaving a battery in storage for longer than this without using could cause the battery to fully discharge as the circuitry of the battery itself consumes power.

Leaving a battery in a laptop while using an electrical outlet for long periods of time will keep the battery in a constant state of charging up and that will reduce the life cycle of the battery.

Remember that when you have removed the dell vostro 1500 battery from a laptop while using with an electrical outlet – the automatic battery backup is no longer functional. Make sure to plug your laptop into an uninterrupted power source (UPS) not directly into an outlet or surge protector.

Do you live in Europe> Typically power supply should only be 110 - 115V
Battery is simply no good any longer. If you can get 2 yrs from a battery you're doing good.

Hope this helps

I think my battery is dead. Do I try to charge it


To charge battery, use a trickle charger at 2 amp. Batteries usually only last about 3 years, so if battery is at that age it probably needs replaced. (Replaced my battery with a lawn mower battery that matched the original battery size.) I would try to get a charge on the battery before replacing it. Replacing the battery could be expensive. Battery could also be low on zinc, water, or acid.

Razor battrey


Did the phone show it was charging on the display? Was the charger firmly connected to the phone? The batteries will go bad after a period of time of recharge cycles. I have bought replacement batteries for my RAZR on eBay. Remove the battery and do a search on eBay for a NEW battery from a dealer using the battery P/N on the battery. I found a higher capacity battery for mine that lasts even longer on a charge than the original one that came with my RAZR. You can do a search on eBay for "RAZR battery". Look at the mAH rating on your battey, Try finding a replacement with the same or higher rating than your original. The higher the mAH rating, the longer it will last between recharge cycles.

Good luck!
