Author Topic: 12v 6ah lead acid battery replacement? (Read 1045 times)

akocdodong · « **on:** December 18, 2011, 05:34:55 PM »

Hi guys, ask ko lang po ano ang alternative ng lead acid battery? Kasi ang bigat po nitong lead acid na to, ang gamit lang naman po nya ay ilaw e.g cathode light n 12v mga 8pcs, amplifier, mp3 player at 2 x 2way speakers na i think 100-200watts...

Ok ang lead acid kasi tumatagal naman like umaabot ako ng 1 hour bago maubos ang kaso kasi ang bigat eh meron po ba kayong alam na alternative or replacement nito na mas magaan kahit di ganon kalakas?

thanks po in advance..

Lithium-Ion. Pero good luck na makakita ka dito sa Pinas. Ginagamit ito sa mga portable power tools gaya ng battery powered screwdriver. Pinakamabuti ito sa Power-to-Weight ratio.

Dodong, and lead acid batt mo ay 12V and 6ah. Pinakamaganda ay Lithium Ion. Marami sto dahil gamit sa Airsoft and RC models. Yung 2200 nasa P1500. 3 kailangan mo para equivalent sa6ah mo. 3s nga parqa 12V. ang mahal ay ang charger, P1800. But you can use just 2 packs. kapag mahina, replace and charge the other one.

Kung metal hydride, mayroon 2700mah or 2.7 ah yan. Again kahit 2 pack. One pack 10 piecs to get 12V. One very good brand is Sony Eneloop...2 may charger P700.

Pricey nga ang mga alternativos.

Ano po ung 2200? is it AH? so what i need is 3 lithium ion to get 6ah?

tsaka about doon sa sanyo po di sony ahehehe 1.2v po bawat isa so x 10 = 12v, right? pano po ung AH?

ano nga ba ang AH na yan? haha di ko gets eh the higher the better ba?

Ang (AH) o (Ah) ay Ampere-hour rating. For example kung 6 Ah ang battery, it has the energy to give you 6 Amps in 1 hour or 1 Amp in 6 hours. Mga Lithium-Ion ay mataas ang voltage per cell, hindi tulad ng NiMH na parang NiCd lang ang voltage per cell ~ 1.25Vdc.

ang mahal pala ng alternative abutin ng 3k pra lang makuha ko ung gusto ko huhu samantalang lead acid 450 lang meron na

oh well pde kaya ang cd-r king na rechargeable battery?

ahehehe tatanong lang nman 2400mAH naman so i'll be needing 10 pcs pra 12v then 2 set pra maging 4.8ah.. tama?

li-poly kaso mahal nga rin if yung mga high capacity

akocdodong · « **Reply #9 on:** December 20, 2011, 12:02:59 AM »

bakit po kaya isinusuggest ninyo eh Lithium-Ion or li-poly which is di naman divisible sa 12v.. kasi 3.7v sya then next is 7.4 next 11.1 then 14.8v, i need 12v po is this even possible?

kasi yan ang hanap mo. yung magaan at may power, pede na yung 3S na li-poly sa requirement mo.

ok if i go for li poly which is better 11.1v or 14.8v?

i found this 2 items

YKS 11.1v 4000MAH 30C
Size: 145mm x 52mm x 23mm
Max charge current: 6A
Lipo batt comes with either xt60 or deans
PRICE: P1,650

or x2 nito

TIGER 7.4v 5400MAH 35C
Size: 150mm x 40mm x 20mm
Discharge rate: 35C
Lipo batt comes with deans plug
PRICE: P1,750

the tiger has a better AH pero mas pricey, if voltage is not an issue and i could go for higher than 11.1v ill go for the expensive yong x2 ng 7.4v 5400MAH pero if 4ah is enough na mas ok ang inaalala ko kasi eh ung sound quality ng speaker kung magbabago ba sya sa lower or higher voltage since meron ding mga nakakabit na cathode light at ilang LED ang gamit ko kasi is 12v lead acid 6ah tumatagal ng 6-8 hours bago malobat pero kahit hanggang 2-3 hours lang solve na ako doon kasi nabibigatan talaga ako sa lead acid

salamat po ng marami sa mga nagsusuggest bobo lang kasi sa electicity eh haha

marce, tama ka bka ng Sanyo. nalito na ako sa brand. kabibili ko sa Chopwise at hinde sa Raon or Divisoriao=o to reduce the risk of peke. Galing. P700 , 2000+mah, with charger. Tumtagal sa camera ko.Dati energizer lang ang gumagana. nagtapon na ako ng pero sa 168 yung ibang brand. Buy with its orig na charger. tested yun..

AT WHAT I MEANT DUN SA TAAS AY LITHIUM POLYMER NOT LITHIUM ION...

safer ka sa 11.1V kung worried ka sa mga nakakabit. at full charge, roughly 4.xV per cell ang lithium, kaya nasa 12V din siya at full charge. with lead acid, nasa 13.5V to 14.5V ang full charge.

meron sa Raon, Sta. Cruz side na, store na puro battery ang tinda. check it out, lampas pa ng roks, katabi ata ng mga nagbebebenta ng mga CCTV. left side from avenida.

bravokilo · « **Reply #16 on:** December 21, 2011, 06:46:29 PM »

Hi eirol, the store you are referring to is probably "ELFOH". Doon siya c`orner ng Raon and F. Cruz, katapat ng Andelness. stga Cruz side yan. Go to Sta. C~ruz, may Chowking dun. Andun yung entrance ng Ongpin. Kung doon kayo papasok, turn ride Raon yun, next street is F. Cruz.Dun and Elfoh. Batteries are them!
