SLA charger

Started by Unknown January 25, 2018
What would be a good multi-stage charger for 12-15Ah 24v SLAs? I'm in UK. Thanks.

SLAs are similar enough to flooded batteries that any good lead-acid charger should work fine.

Google "Mean Well" I assume they offer worldwide distribution.

I've googled em, and they just don't provide enough information. https://www.tme.eu/gb/details/gc160a48-r7b/chargers/mean-well/?brutto=1&gclid=Cj0KCQiAwKvTBRC2ARIsAL0Dgk0LsorTg_dHHBo_QKvm8hxFdkvlo8XgMzXlsuCQ5exhFnjh0tqOsCcaAlJoEALw_wcB for example. Does it have temperature compensation? Who knows. I don't understand suppliers that just fail to provide the relevant info when retailing. NT

Informative, though their charger is little use. Input 9-36v dc, max 7Ah for some reason. NT

I've been looking again at this one, it never got solved. Meanwell: the only possible contender is https://www.tme.eu/gb/details/pb-230-24/chargers/mean-well/ but the charge & float voltages are too high for SLAs, so I think it's no go. I thought I'd look on ebay & amazon... mixed results, the main question being completely unknown quality from unknown chinese/hk sellers £27.99+0. 4 stage, for SLAs. Sounds good except all the customer reviews are all in Chinglish! I smell a fairly large rodent. https://www.amazon.co.uk/dp/B0776PZLXN/ref=sspa_dk_detail_3?psc=1&smid=AR43LS1X3DZXK This looks more interesting: £24.75+0 Anjing 12/24v https://www.amazon.co.uk/Espeedy-Electric-Battery-Intelligent-Automobile/dp/B0777P6B75/ref=sr_1_12?ie=UTF8&qid=1519333902&sr=8-12&keywords=24v+stage+battery+charger 4 stage charging plus 'pulse auto revive.' No idea if that approach works much, if it does I have a deadun as well I could try it on. quote... stopped automatic when charge full,pulse auto revive and maintenance battery ,include 5-stage mode:Idle mode,Constant curren,Constant Voltage,Floating charge mode,Trickle charge mode. cuts out at 105C! This product is applicable to the 12V/24V 200 AH lead acid battery ,including GEL,UPS,wet battery and maintenance-free battery.Advanced pulse width modulation (PWM) technology is used to automatically charge batteries through a 4-stage charging cycle Notice:The 12V input when automatic charging mode,Full electric voltage of 13.8V to 14.3V,about 16V input when manual charging mode,must be artificial monitoring in case of overcharge if manual mode charging,suggest stop charging when the battery beating. The V, I & % meter would also be a welcome plus, at least if reasonably functional. MBTF is anyone's guess. Any more ideas or feedback welcome NT
