I have two local Batteries Plus stores, nearly equidistant, and so I drove to one without first price shopping, and frankly, was a little disappointed with their prices. Unfortunately, they seem to be using "house numbers" on the two models of cells that I bought, as well as for another model of cell I didn't purchase because they only had five in stock at that store but the pack I was replacing uses six, and while they did claim to have larger capacities than the cells they were replacing, their capacity values in those sizes were uncommon, making direct price comparisons impossible.
I needed eight cells for my Sencore 953i, and they measure about 16 x 48 mm and the original ones are rated as 1400 AH. Batteries Plus sold me eight 2700 AH cells for $6.79 each, loose with no tabs,, but I see that someone called Powerizer. at www.batteryspace.com
, can sell me two, ten cell packs of 2200 AH batteries that look like they are that physical size for just $39.95, which is $2 per cell, and while their capacity is about 20% less than the Batteries Plus cells, it is still over 50% greater than the original ones, and they are soldered together in a pack for that price. http://www.batteryspace.com/nimhbatterypacktwo12v2200mahnimhbatterypackswithtab.aspx
Similarly, I bought ten, sub C 2700 AH cells for $5.98 each, loose with no tabs, but Powerizer / www.batteryspace.com
will sell me two, ten cell packs of sub C cells with 1600 AH capacity, which is the same as my original equipment came with, for $28.95, or about $1.45 per cell. http://www.batteryspace.com/nimhbatterypacktwo160v1200mahnimh10x23abatterypackforminirobot.aspx
Actually, because the meter that uses that latter pack is a pig with a CRT, it might be a better value for me to pay four times as much for a roughly 70% increase in capacity, but I may look around for a better value on some sub C packs with maybe 2200 or 2500 AH capacities at better prices.Edited by AntAltMike - 6/25/13 at 9:33am
