Will it hurt my device? It"s a tennis ball an equipment and the charger is claimed to fee the battery in it. Thx

Will that hurt my device? It"s a tennis ball device and the charger is supposed to charge the battery in it. Thx
it wont fee them
it wont charge them

to fee a battery girlfriend need an ext voltage 보다 the voltage that the batteryso if you already have a 15 volt charger the points to a 12 volt battery thus12 volt charger will not fee it you require a distinction of volt to charge the battery

thx, find out something brand-new everyday. So my 15 volt 1 amp charger quit working, ns hooked increase a multimeter to it and it claims it"s 20 volt! What would cause this, and what space the opportunities I hosed my battery? So i bought this universal laptop charger also though I"m only charging a tennis ball machine because it"s 15v and has the 5.5mm 2.5mm tip I need. Commonly laptop chargers are 3+ amps however this charger doesn"t state anything. Are these smart chargers and also will lock auto adjust?http://www.amazon.com/gp/product/B00849BPFI/Thanks

you need a charger capable to take care of the batteries you havelead acid??lion??lifepo4??niCd??each battery has different volt in ~ which the is charged.and batteries have a maximum safe volt charged. A 12 volt lead mountain battery is take into consideration charged once it will 14,5 volt and also never must go past 15 volts.so what the charger is doing is measure the voltage of her batterie to know when come stopwrong charger and also the charger will store sharging and also kill your batterieif you fee them in ~ 20 voltwell pretty certain they room gone
hmm my understanding of this ingredient is quite laughablethe tennis ball device uses 2 of these batteries slahttp://www.azbatterystore.com/Tennis_Ball_Machine-12_Volt_9_Amp_Battery.htmlthey speak 12 volt.

You room confusing battery voltage with charging voltage. 12v lead acid is nominally 12.6v completely charged. Charging voltage is generally 13.8-14.4. Maintain charge needs something more in the 13ish range.One the is fee at 15v+ until death will still only read in the 13v range.edit: and also if that connect is correct, 15v would smoke the battery. Even if it"s actually 12v rather of 12.6, a car battery charger should work fine. If girlfriend wanna it is in ghetto, begin your car and hook the up favor you would if jump-starting. Just don"t reprimand me if you short something and also start a fire. Or blow up the battery.

If your initial charger was 15 volt that method you need that much electrical pressure to ingredient electrons right into that battery.
