If the unit is using a wet cell acid battery, it's possible that dirt mixed with hydrogen build up on top of the battery caused the second failure. The battery top should be kept clean and should be checked at least 4 times per year. Any stray ignition source can cause the hydrogen to explode, including lightning.

It's also possible that the battery float charger needs to be adjusted or possibly has a problem. Some float chargers are adjustable. The higher the charging rate the more off-gassing the battery will experience and increase the chance of a failure.

If the battery has exploded, the entire generator and housing should be cleaned (washed) thoroughly to remove any remaining battery electrolyte (acid).

Be careful - if you aren't comfortable working on this type of equipment, it's best to call a local dealer and find a service vendor.

B&S Model 040229 12kw has LCD display with 9999 code, what does it mean. It had a dead battery

Fault codes on this unit are usually 1 thru 8, or FC_1 thru FC_8.
You will need a usable battery installed for the control panel to operate. If you still get 9999 with a good battery, you will need to test it with a known good control panel, which may be the problem.

I left my Garmin 765t GPS in the car over a very cold night and since then the unit doesn't recharge. Please help Thank you Bill

While the rechargeable lithium-ion batteries inside the GPS can operate in a fairly wide temperature range, leaving the battery out in anything less than -10 weather will render the battery inoperable. Unfortunately your battery has probably been exposed to a lower temperature, and therefore will no longer take a charge. You will have to replace the battery. Depending on the retail source that you bought it from you should be able to purchase a replacement unit from them. On a side note, lithium batteries normally have a 3 year lifespan, and you would have to replace after that time-frame.

Thank you for the opportunity to assist you in resolving your issue. Should you need further information or assistance please do not hesitate to let us know.

My daughters IPOD Touch (2nd generation) only holds a charge now for about 1 hour. She has had it for 3 years. Do I need to replace the battery? How is this done?

The battery is sodered into the device, I would contact Apple although most likely you are out of warranty at 3 years. I believe the replacement price is around 150$?

I have a Bosch GWH 425 HN Tankless Hot Water Heater...On 2/28/2010, it began intermittant exploding when demand for hot water occurred. Local technicians worked on the unit several times, changed and...

I have the same problem with the same model. The problem has been identified by a friend of mine, correctly, I think.
This is a very dangerous problem involving Bosch's much touted safety feature, ironically enough. IT IS THE FLAME SENSOR IN THE GAS VALVE. The flame sensor is supposed to confirm that the pilot has lighted BEFORE the main gas line sends gas to the main burners, after which the pilot shuts off. The pilot light is not coming on, the sensor that shouldn't let gas fto the main burners is failing and the main gas is flowing and ignighting from the spark that is supposed to light only the pilot in a big explosion.
This is the 2nd unit of this model that has failed. I think Bosch should do a recall

Same problem, generator kicked in after power outage,

At the point the transfer switchis suppose to transfer put a dc volt meter across terminals 23 and 194 in the transfer if you do not show 12VDC. Then you have a relay hanging upon the PCB board in the generator, need to replace board. If you are showing 12VDC and the switch is not transferring the problem is in the switch itself.
