Microtek Inverter not fully charging the batteries

I have a 6 months old Microtek 3KVA Inverter which is connected in series to 4 Brand New Exide IN 1500 Plus 150Ah rating Inverter Batteries (48 Volts system). Though the inverter charging LED indicates that the batteries are fully charged (battery charging indicator light stops flickering) none of the indicators in the four batteries show the typical green glow in the visual charge indicator. Upon connecting an ammeter in series to check for the charge current the ammeter registered only 2-3 amps initially and later dropped down to 0 Amps. What I understand from this test is that the Inverter circuitry has sensed that the battery does not require any further charging and therfore the charging amperes is zero. If this is an indication to show that the batteries are fully charged, why have the glow indicators in the battery failed to indicate green, typical color of a fully charged Exide IN 1500Plus inverter Battery.

2005 Mozda. Tribune. I put a new battery on it, drove it 150 miles, the gauge flicked, the car stalled and would not start. What would be the problems:


Have the battery tested. Even though the battery is "new" it may have been out dated, could have sat on a concrete floor wish drains the battery, could have a bad cell and so on.
Retailers should check dates on batteries and remove and replace once they are 6 months old. Unfortunately some places just don't do it or they do but some get missed.
If you look on the battery, depending on brand, they generally have 2 stickers on the side one is manufacture date and one is shipped date. If the shipped date is more than 6 months old the battery may not be fully charged.
I hope this helps.

My battery charges but only lasts about 20 minutes once it says it is fully charged. Just purchsed a new battery thinking it was old (laptop is about 3 years old) and the same thing happens.


From what you describe and assuming the new battery was "new", I'd say you have an internal short which is draining the battery over a short period of time. I'd also investigate the accuracy of the battery charge indicator. Download this free utility which will give you a more accurate picture of your battery:

I'm assuming you gave the battery a "commissioning charge" when you bought and used it?
If not, this is something you should do with all new LI batteries. This bit is reproduced from a website that sells batteries for the Toshiba satellite series:

"2. The new Toshiba Satellite a205-s4777 battery pack needs to be circled (fully discharged and recharged) three to five times to reach its optimum performance.
3. Toshiba Satellite a205-s4777 battery will undergo self-discharging when left unused for a long period of time. Thus, it should always be stored in a fully charged state and kept in a cool, dry and clean place.
4. It is normal if the new Toshiba Satellite a205-s4777 battery gets warm when being charged or used. However, please pay special attention if the battery pack becomes excessively hot. This may indicate there is a problem with the charging circuit of the electronic device. Please consult a qualified technician if necessary.
5. To maintain the optimum performance of Toshiba Satellite a205-s4777 battery pack, it is highly recommended to circle (fully discharging and recharging) it at least once a month.
6. New batteries are hard to be charged. Sometimes, your electronic device may indicate a fully charged condition about 10 to 15 minutes when Toshiba Satellite a205-s4777 battery pack is being charged for the first time. When this happens, remove the battery pack and let it cool down for about 10 to 15 minutes then repeat the charging procedure. Sometimes, the new Satellite a205-s4777 battery will suddenly refuse to be charged. If this happens, a suggested solution is trying to remove the battery from the device and insert it again. "

My 24v 1500w inverter cuts out when i use my 700w microwave?


Normal 0 MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman";} The starts up power for some appliances we use at home are sometimes higher than their actual power. For example a fridge will start with a power of 2 to 3kva then after start up it goes down to its normal power of 700va to 1kva .
Your inverter will continue to switch off if your if you battery is
  1. Low i.e. it is not fully charged
  2. Has a low ampere rating
The solution is to get a battery with a higher ampere rating like 200ampere/hour and above, connect it in parallel to the other battery i.e. the positive terminal to the positive terminal, the negative terminal to the negative terminal. This additional will accommodate the excess power needed for the microwave to start up.

Note that it is not advisable, to use this type of power appliance on a small inverter .Use a battery with the same volt rating i.e. a if you use a 24volts battery get another 24volts battery with a higher ampere rating

No power with a brand new battery, not even ignition lights


Did you check your brand new battery? Fully charged? Hydro was good? You are connected properly ( + = + and - = - ) Do a volt check yourselg between + and - (frame)

If yes to all, Id be looking at the ignition switch.
