Please contact one of our techs at tech@batterystuff.com. I’m doing a summer project and was wondering about deep cycle batteries. Proper temperature compensated float voltage should be used to achieve the best results. The next day one TM battery was like 80% and the other 90%…after 12 hours on the juice. I know you have higher quality chargers listed, which is great, but I don’t know what type of charger I can use at all. Most modern cell phones, laptop and tablet computers, and most electric vehicles use Lithium-ion batteries. 4. Use the link below to see our large selection of battery chargers and 12v/24v trickle chargers. Paul I have a 2 amp 12 volt battery sealed lead acid can I use a charger that have 4 amps 12 volt auto shut off.

All of this has me confused. Others require a fast and powerful charger to quickly restore a trolling motor battery or a wheelchair battery set. Smart chargers are the best type: they detect when cells are fully charged and will automatically switch to trickle mode. What does the charger do differently in AGM mode? We have also selected a 400w continuous use/800w peak power inverter to use. Some folks require a charger to keep their motorcycle, classic car, or aircraft battery charged during the offseason. In larger applications, the current of the battery charger is sufficient only to provide a maintenance or trickle current (trickle is commonly the last charging stage of most battery chargers). Fast chargers make use of control circuitry to rapidly charge the batteries without damaging any of the cells in the battery. Simple chargers. Jeremy Fear Yes a surge protector will be a good idea. You sell intelligent chargers, now until recently I‘d never seen intelligent chargers with high single digit AH rates let alone double digit AH rates. The normal consumption is probably only 600w. The reason this works is the charge is spread out among both batteries, and not just one. Not all chargers are compatible with all types of batteries. First if your going to use the inverter you will need the Calculator | DC to AC amperage conversion run through an Inverter to obtain your DC Amp Draw. Chargers normally incorporate some form of voltage regulation to control the charging voltage applied to the battery. BatteryStuff Tech Please keep in mind we only recommend interconnecting batteries that are of the same age, capacity, chemistry, and if you plan to employ them as a battery pack. is this ok ? Thanks, These batteries employ a sulfuric acid electrolyte and can generally be charged and discharged without exhibiting memory effect, though sulfation (a chemical reaction in the battery which deposits a layer of sulfates on the lead) will occur over time. Some smart chargers are designed to charge: The output current of a smart charger depends upon the battery's state. Great site by the way, we have nothing similar in the UK which is where w are based, but the electrical info is international! An intelligent charger may monitor the battery's voltage, temperature or time under charge to determine the optimum charge current and to terminate charging. BatteryStuff Tech Yes, that charger is in the recommended range of 10-25% capacity. I’m having a hard time knowing what type of charger to purchase, as I’m on a tight budget. Dave Bort hi my camper currently runs 2 100ah agm batteries and 1 110ah flooded battery .i have just installed a 100w solar pannel and 10a regultor how should i set the regulator …..for flooded or agm ? This will determine what I recommend as far as good charge rate goes. Patrick My battery charger (HP-1202B 24V2A) for my Phantom wheel chair does not work any more (I think it overheated). They can charge the batteries and at the same time supply a load to your applications up to the rated charge rate of the charger (in amps). You will most likely have to contact the CPAP manufacturer for a 12v accessory meant to run the machine directly off the battery, but it is far more efficient. A battery charger, or recharger, is a device used to put energy into a secondary cell or rechargeable battery by forcing an electric current through it. 50% depth of discharge per cycle is our recommendation because it‘s the most cost effective solution. So not only does it take an age to charge it never fully charges. I also don‘t want to wait 12-hours to have fully charged batteries. Such chargers are permanently installed and equipped with temperature compensation, supervisory alarms for various system faults, and often redundant independent power supplies and redundant rectifier systems. Tripp I had never seen this on your page before, well done! I have a electric van, batteries: 18 in series per row, 3 of those rows in parallel, mounting to 54 batteries. Open Circuit Voltage (fully charged): 13.1 volts Rapid charging results in even faster recharge times and is limited only by available AC power, battery type, and the type of charging system.[21]. Timer based chargers also had the drawback that charging batteries that were not fully discharged, even if those batteries were of the correct capacity for the particular timed charger, would result in over-charging. Now I may well use a low rated intelligent charger to keep my battery conditioned when at home but what about on site? 10%-35% of the battery capacity is safe range to charge with. Both these chargers are mountable chargers meant to be mounted in the boat with the battery, so they only come with ring connections to be mounted to the battery. These regulated taper chargers do not allow the voltage to reach more than a trickle charge. The starting battery was was obviously fully charged each day; however, depending on the TM battery, one may have been about 90% charged; the other in it‘s final stage (like 98%). On the 10 amp rate the regulated voltage is just over 16 volts near full charge. Herb Korn Very informative.
