Problems with charging battery - AF54.10-P-6005A

MODEL 124, 126, 129, 140, 163, 168, 170, 201, 202, 203, 208, 209, 210, 215, 220, 230, 461, 463 with mat battery 

Damage code	Cause	Remedy
54 001	Risk of explosion  caused by oxyhydrogen gas. Risk of poisoning and caustic burns  caused by swallowing battery acid. Risk of injury  caused by burns to skin and eyes from battery acid or when handling damaged lead-acid batteries	No fire, sparks, open flames or smoking. Wear acid-resistant gloves, clothing and safety glasses. Pour battery acid only into suitable and appropriately marked containers.	AS54.10-Z-0001-01A
	Most workshop battery chargers require a counter voltage (>7 V) from the battery to be charged in order to start the charging operation. This allows the charger to recognize whether the polarity is connected properly.	Since mat batteries are not necessarily defective, even at such low voltages (<7 V), proceed as follows if you encounter the problems mentioned above when charging: ↓
	Discharge mat batteries with a voltage <7 V are not "recognized" depending on the type of charger and therefore not charged.	Before charging, connect a second "good (12 V)" battery in parallel with the mat battery.
		1 Connect battery in parallel to the mat battery.
		Model 129, 163, 168, 170, 202, 208, 210	AR54.10-P-1130Z
		Model 203, 209	AR54.10-P-1130P
		Model 215, 220, 230 As soon as the two batteries are connected in parallel, a compensating current can flow. Here, particular caution is required when connecting and disconnecting the cables (arcing).	AR54.10-P-1130I
		2 Start charging operation Charge for a maximum of 1 hour.
		3 Remove second battery
		If necessary: ↓ 4 Recharge second battery.
		5 Measure voltage of mat battery. At a value of > 7 V, a new attempt should be made to recharge the battery: ↓
		6 Charge battery again.
		Warranty will be recognized only when the above procedure is observed. Newer chargers can be recoded for voltages <7V.
